LOCATION AND SERVICES REQUIRED: This section deals with the services that your cabinet will require to function properly, and advice on where to locate the cabinet. GENERAL: This equipment is designed to operate under the following ambient conditions:

Indoor use only.

Ambient temperature range: 10º to 35ºC

Ambient humidity range: Maximum relative humidity of 80% for ambient temperatures up to 25ºC.

Optimum performance of chamber is achieved when the ambient temperature is within a 20ºC to 25ºC range.

LOCATION: Place the cabinet in a well-ventilated area on a firm level surface. Allow sufficient space around the back and sides of the cabinet to provide adequate ventilation. Recommended space of 30cm on the sides and at least 10cm at the rear (Note: with spacers attached). Ensure that there is sufficient room to allow the doors to open. SERVICES: ELECTRICAL: Confirm that the power supply is suitable for this equipment. Refer to the equipment rating plate for details. Model: TRH-1250 15 Amp 240V 50Hz TRH-2000 15 Amp 240V 50Hz Note: This equipment requires a 15 amp power point (otherwise known as a general purpose outlet or gpo). You will notice that it has a large earth pin and will not plug into a standard power point. WARNING: Ensure that the electrical outlet is earthed and is of the correct voltage and is capable of carrying the stated current load. WATER: A water supply is required for the humidifier (steam generator). Since the water level in the humidifier tank is automatically regulated, the water supply can come from either mains water or from a gravity fed water reservoir. If the water supply is from the mains, we recommend that it should be filtered to prevent the build-up of mineral salts and residual deposits frequently found in town water. It is advisable that a Sediment filter and an Activated Charcoal filter be installed in the water supply line to help keep the total residual deposits down to a minimum. The humidifier is constantly “on the boil” to provide steam for humidity, and therefore evaporation will leave mineral deposits behind. Failure to keep the Total Residual Deposits to a minimum can result in premature failure of the Humidifier Tank. An alternative method to Mains water is to use a water supply from a gravity fed tank. Thermoline supply an optional 25 litre water tank complete with flexible hose and connection fittings. This should be elevated by at least 1 metre and filled with water, the 25 litres would last at least 2 ½ days even under the worst operating conditions. The gravity fed water supply has a number of advantages over mains water supply:

Firstly, the water in the tank can be “treated water” such as distilled water or deionised water. The deionised water does have the potential under certain conditions to corrode stainless steel (Refer to Caring for stainless steel on page 30). Using distilled water will not leave the mineral salt deposits behind that town water does, this will increase the life of the humidifier and reduce maintenance.

Secondly, if the automatic water level controls were to fail or if there was a water leak, the worst spillage will only be 25 litres of water instead of a potential flood.

It is advisable that the water to the Humidifier be filtered to prevent the build-up of residual solids. A Sediment Filter along with an Activated Charcoal Filter would be ideal.

6 | P a g e

DRAIN: Because we are controlling humidity levels inside the cabinet, there will always be water condensing and coming out of the drain inside the cabinet. There is also a drain valve on the humidifier tank for maintenance, and an overflow pipe in case of a malfunction. Therefore it is essential that the location for the cabinet has a floor drain for the water to flow into. Water from the cabinet will exit through a 19mm drain pipe at the rear of the cabinet, you will need to connect this drain pipe to the floor drain (see note below).

IT IS IMPORTANT THAT THE CHAMBER DRAIN OUTLET BE CONNECTED TO A SUITABLE WASTE OUTLET (DRAIN) AT ALL TIMES. MAKE SURE THAT THERE ARE NO RESTRICTIONS IN THE DRAIN PIPE, IT WILL NEED TO BE ABLE TO COPE WITH AN OVERFLOW OF 3 LITRES PER MINUTE IN THE CASE OF A FAULT.

WE ADVISE THAT THE WATER SUPPLY AND THE DRAIN PIPES SHOULD BE FLEXIBLE. THIS WILL ALLOW THE CABINET TO BE MOVED AWAY FROM THE WALL FOR ACCESS TO THE REAR OF THE CABINET DURING SERVICE.

ASSEMBLY & INSTALLATION: ASSEMBLY: SHELVES: 4 stainless steel clips are supplied for each shelf. Determine the space required between each shelf level, and simply hook the clips into the slotted strip attached to the walls. Place the shelves on top the stainless clips. PERSPEX HOLDER: This holder is provided so that the operating manual can be kept with the equipment. The operator can use the 2 x screws mounted on the left hand side of the cabinet to fix the Perspex holder to the cabinet. (See figure 1 for location). WALL SPACING RODS: 2 threaded rods are provided that screw into the rear of the cabinet to prevent it from being pushed too close to a wall. A minimum distance of 100mm is maintained with the use of these spacers. See Figure 1. Figure 1: Showing installation of wall spacing rods, location of drain and water-in connections, and location

for the instruction manual holder.

INSTALLATION:

Locate the cabinet in a well ventilated area on a firm level surface as described earlier. Make sure that the 2 x wall spacing rods are screwed into the frame at the rear of the cabinet (See figure 1). This will ensure that the air flow through the refrigeration condenser is not impeded.

Leave sufficient room at the rear and sides for air flow around the cabinet as previously described (30cm each side).

Leave enough room in front of the doors to allow them to open fully when loading the cabinet.

Connect the drain pipe at the rear of the cabinet (figure 1), to a suitable floor drain with flexible hose (drain pipe is 19mm diameter).

The cabinet is fitted with castor wheels so that it can easily be moved during installation. The castors also allow the cabinet to be moved for access to the rear during service. Once the cabinet is in place it can be immobilised by means of the adjustable feet at the two front corners of the base. Use a spanner to wind these feet out until they touch the floor.

Connect the water supply to the cabinet, either mains water or gravity fed, to the snap on connector located at the rear of the cabinet (figure 1).

Note: Gravity fed water tank should be at least 1 metre above the ground, to provide a suitable head for the water to flow properly.

Before turning on the water supply or the power, make sure that the drain valve on the humidifier is turned off. The humidifier is located in the area below the doors. Open the hinged panel below the doors to gain access to the humidifier (see photo below). The drain valve is shown in the closed position.

Plug the power cable into the power point. Note: this cabinet requires a 15 amp, 240 volt power point, a standard 10 amp power point is not adequate.

You are now ready to use the cabinet!

FUNCTION: This equipment is used to provide an economical and accurate temperature and humidity controlled environment for laboratory evaluation and long term storage of products, within the range shown below in the TRH control envelope.

WARNING: Do not use flammable solvents or combustible materials as fire or explosion may occur. This equipment uses components which may be a source of ignition.

PERFORMANCE

The operating range for this equipment is +10°C to 60C and 10% to 95% RH

MAXIMUM TEMPERATURE MAXIMUM HUMIDITY

For this product is 60C For this product is 95% RH. C-TICK The equipment referred to here complies with requirement of AS/NZS 1044:1995 electromagnetic interference (EMI). PRINCIPLE OF OPERATION: Read this section in conjunction with figure 2. This will give the operator a guide on how the cabinet actually controls the conditions within the workspace. CONTROLS: Temperature and Humidity is controlled by the STAR-700 touchscreen controller. This is mounted on the front door of the TRH cabinet. AIR CIRCULATION: In order to maintain close temperature and humidity tolerances, good air flow is required. Three centrifugal fan wheels driven by externally mounted motors, draw the air through a “conditioning area” below the false floor inside the cabinet. The fan wheels then force the air up the rear perforated panel to be evenly distributed horizontally across each shelf level. Air then returns to the “conditioning area” through slots in the floor, for the conditioning cycle to start again.

9 | P a g e

TEMPERATURE: The air is heated by means of an element below the false floor, and cooled by means of the bare pipe evaporator. The refrigeration unit is located in the area below the cabinet. The STAR-700 controller cycles the heating and cooling to maintain stable temperature. HUMIDITY: The air is humidified by steam from the steam generator located in the area below the main cabinet. We call the steam generator the “humidifier”. Steam from the humidifier enters the conditioning area by means of a steam pipe. The air is dehumidified by the same bare pipe evaporator used to cool the air temperature. The STAR-700 controller cycles between humidifying and dehumidifying to maintain stable humidity.

EXPLANATION OF CONTROLS Access: The STAR-700 Controller is located in the front door. On initial power up the STAR-700 displays the screensaver. See STAR-700 Operating Guidelines on how to exit screensaver mode.

Figure 3: Control Panel. Temperature/Humidity Control: The STAR-700 microprocessor controller allows accurate control of the Temperature and Humidity with in the cabinet. High & Low Temperature Alarm: The STAR-700 microprocessor controller has a High and Low temperature alarm which will become active if the actual temperature deviates the set value by +/-5.0degC. In the event of a High Temperature Alarm all sources of heating are electrically isolated. In the event of a Low Temperature Alarm the refrigeration compressor is isolated Humidity Trip Light: This is located on the Humidifier itself and can only be viewed through the access door at the front near the floor. This light should only be illuminated when a failure of the water supply to the humidifier occurs and the floats switch interlock fails, causing an over temperature condition in the humidifier. To Reset: First correct the water supply fault, then reset the manual reset safety thermostat at the front of the humidifier (small red button), located behind the hinged access door at the front of the cabinet. (See figure 4).

OPERATING THE CABINET

1) Ensure that the cabinet is located as previously described, refer to the index, LOCATION, Page 4.

2) Loading/Unloading the Cabinet Load Distribution

There is a direct relationship between the temperature/humidity uniformity throughout the workspace and the air distribution. If the air cannot freely circulate, then the controlled conditions cannot be maintained. The air enters the workspace through the rear perforated panel flowing in a forward direction through the stored product before entering the conditioning area via the perforations at the floor panels. Product under evaluation should not be placed against the rear perforated panel and side walls or over the return air grill at the floor of the chamber.

3) Door Opening

When the doors are open, the controlled conditions will begin to deteriorate. To minimise losses always close the doors as soon as practical. Should the doors be opened for a long time, then the control may extend the time to return to the set conditions beyond that normally expected.

‘STAR-700’ TOUCHSCREEN OPERATING GUIDELINES. Safe Operating Value (SOV).

On initial Power up the STAR-700 Touchscreen shows the Screen Saver page. See Below Image. On Initial power up cabinet controls the ‘Safe Operating Value’ only. The Touchscreen is fitted with a Security Screensaver to stop unauthorised access to the controlling parameters. This Security Screensaver becomes active if the Touchscreen has not been touched for more than 5minutes or if power is cycled.

To exit out of the Security Screensaver simply press the ‘Press to Log In & Exit Screensaver’ Button. The User Access window will appear. To exit out of the Security Screensaver and enter into the Main Menu Screen use the following passcodes: User Number: 1 Passcodes: 1111

These passcode should only be given to Authorised Personnel. To enter the User Number and/or the Passcode simply press the Numeric Window and the Numeric Keyboard will be displayed. Simply enter the User Number and/or the Password and press enter. Once you have pressed enter press the screen anywhere above the Login Button and the Main Menu screen will appear.

When in the Main Menu Screen you will notice that the indicator in the top right corner states that the Diurnal/Program Cycle is Off. The Values below the heading ‘Safe Operating Value’ are the current set values and the controller will start to control these values. During ‘Safe Operating Value’ control, the Lights can only be manually operated by using the drop down menu underneath the heading ‘Lights (SOV)’. The ‘Lights SOV’ is a manual operation of the Lights, in the ON mode they are continually on and in the OFF mode they are continually off. To operate the Lights on a Diurnal/Program Cycle the operator will need set up the Diurnal/Program Cycle. To change the ‘Safe Operating Value’ simply touch the ‘Operating Value’ box. A popup numeric keypad is displayed. Type in the new value and press enter. The cabinet will automatically control the new ‘Safe Operating Value’.

The ‘Safe Operating Value’ has been designed to be set by the operator to a safe condition that will not cause damage to any of the Research, Experimental and/or Plant Material within the cabinet, in the event of a power failure. If the controller is operating in ‘Diurnal/Program Cycle’ mode and there is a power failure, on resumption of power the ‘Diurnal/Program Cycle’ mode will stop and the cabinet will be controlled at the ‘Safe Operating Value’.

Each program can be set as an independent program or can be linked to create one large or multiple large programs. This is achieved by not using an End segment in a particular program. For example if your program requires the use of 15 segments we can use the 10 segments of Program 1 and the first 5 segments of Program 2 making Segment 15 (5th Segment of Program 2) an End Segment type. We would then star program 1 and as the program runs through the first 10 segments of program 1 and because there is no end segment in Program 1 it continues to run program 2 until it find the end segment at segment 15.

When linking multiple Programs, to use more than 10 segments, the programs need to be sequential. By pressing on Program 1 the following screen is displayed. The below example is a Diurnal cycle of 40degC and 40% day and 10degC and 80% Night. Assuming that 40degC is at midday this program has been written to start at 25degC and 60%RH assuming that the day condition of 40degC and 40%RH is Midday then this program would Start at 6am.

Program 1 Segment 1-5

Program 1 Segment 6-10

The following is a description of what each of the items in the Program are and what function they perform.

17 | P a g e

Segment Type: The segment type can either be a Time, Jump To, or End type. Time: This determines that the segment is a period of

time. The time is set in Hours, Minutes and Seconds.

Jump To: This allows the program to repeat a predetermined set of segments. By selecting the ‘Jump To’ parameter in segment type and then entering a segment value at the ‘Jump To’ parameter, will tell the program were to jump back to. At ‘Jump Cycle’ enter how many times it jumps back to or repeats the predetermined set of segments. See Example on next page.

End: This tells the program when to end. There has to be an end segment. Failure to enter an end segment will cause the controller to indefinitely dwell at the last segment.

Jump To: The operator would enter the segment number that the program will jump back to. This value is ignored if the segment is set to either a Time or End Segment.

Jump Cycle: The operator would enter a value here as to how many times the ‘Jump To’ repeats itself. A value of 0 will continually repeat the Jump To segments until the operator ends the Program Cycle manually. This value is ignored if the Segment Type is set to either a Time or End Segment.

Temperature: The operator would enter the Temperature they require the cabinet to achieve. This value is ignored if the segment’s Step Type is Jump To.

Humidity: The operator would enter the Humidity they require the cabinet to achieve. This value is ignored if the segment’s Step Type is Jump To.

Co2: The operator would enter the Co2 they require the cabinet to achieve. This value is ignored if the segment’s Step Type is Jump To.

Hours: The operator would enter the required length of time for the segment in Hours. This value is ignored if the segment Step Type is set to either Jump To or End.

Minutes: The operator would enter the required length of time for the segment in Minutes. This value is ignored if the segment Step Type is set to either Jump To or End.

Seconds: The operator would enter the required length of time for the segment in Seconds. This value is ignored if the segment Step Type is set to either Jump To or End.

End Action: This value determines what will happen when the program ends. It can be

set to SOV, which stops the program from operating and controls the Safe Operating Values. Or it can be set to dwell, in which case it will continue to control the Temperature, Humidity and Co2 of the last Time segment.

G’Soak Temp: This is the Guaranteed Soak Parameter and is only visible if the Guaranteed Soak is enabled. This parameter is generally not used on the Climatron range of Plant Growth Cabinets as it can extend the time of a Diurnal Program effectively making the Diurnal Cycle longer than 24hours. The Guaranteed Soak allows the Program to maintain its Programmed Temperature Value for the duration of the Segment Time by automatically placing the Program into a holding pattern and not allowing the program to proceed if the Actual Temperature Value deviates the Programmed Temperature Value by a predetermined value. Once the Actual Temperature Value is within the predetermine range then the Program will automatically continue.

G’Soak Humidity: This is the Guaranteed Soak Parameter and is only visible if the Guaranteed Soak is enabled. This parameter is generally not used on the Climatron range of Plant Growth Cabinets as it can extend the time of a Diurnal Program effectively making the Diurnal Cycle longer than 24hours. The Guaranteed Soak allows the Program to maintain its Programmed Humidity Value for the duration of the Segment Time by automatically placing the Program into a holding pattern and not allowing the program to proceed if the Actual Humidity Value deviates the Programmed Humidity Value by a predetermined value. Once the Actual Humidity Value is within the predetermine range then the Program will automatically continue.

G’Soak CO2: This is the Guaranteed Soak Parameter and is only visible if the Guaranteed Soak is enabled. This parameter is generally not used on the Climatron range of Plant Growth Cabinets as it can extend the time of a Diurnal Program effectively making the Diurnal Cycle longer than 24hours. The Guaranteed Soak allows the Program to maintain its Programmed CO2 Value for the duration of the Segment Time by automatically placing the Program into a holding pattern and not allowing the program to proceed if the Actual CO2 Value deviates the Programmed CO2 Value by a predetermined value. Once the Actual CO2 Value is within the predetermine range then the Program will automatically continue.

Lighting/Event Outputs.

At each segment page there is a Lighting/Events button. By pressing this button the display

shows Eight events that can be turned ON and OFF for each segment. The First Event which is generally labelled Lights is what turns the lights ON and/or Off. A total number of Eight Lighting/Event Outputs are available, however only the required hardware is fitted per cabinet.

Program Features. There are a few other features of the program that cannot be changed but are described below. Guaranteed Soak: This is a tolerance value, set at +/-2.0degC, and guarantees that the

Program Set Values for Temperature only are reached. If during a program cycle the Actual Temperature deviates the Program Set Value (PSV) by more than +/-2.0degC the program will be put into a hold mode until the Actual Temperature is within the PSV. There is no Guaranteed Soak on the Humidity Value or the Co2 value. These values can deviate without the program going into a hold mode.

Program Start Value: The Program starts at whatever the Actual Temperature, Humidity and Co2 are. If when starting the program the Actual Temperature is more than +/-2.0degC from Segment 1’s PSV the Guaranteed Soak value will hold the program until it reaches Segment 1’s target temperature.

Power Failure: In the event of a power failure the Program Cycle will end. On

resumption of power the cabinet will control the Safe Operating Values.

Starting the Diurnal/Program. The following screen shows the Diurnal/Program Set-Up screen. Once the desired program has been set up then the operator will need to enter the desired program number value into Start Program Number. Once the desire value has been entered the operator can then start the program by using the drop down menu. The following describes the item and the function of the parameters in the drop down menu. End The end parameter is what stops a current running program from operating Start The Start parameter is what starts the program that is entered into the Start

Program Number. Pause The Pause Parameter will simply pause the program at its present point. It

will hold this point until the resume parameters is selected. If the Start parameter is selected while a program is in pause it can restart the program from the beginning.

Resume The Resume parameter will resume a program after it has been paused.

Diurnal/Program Set Up Screen.

Note: The Program can be Started, Stopped, Paused and Resumed in the Main Menu Screen. However you cannot select the Program Number in the Main Menu Screen. When the program is operating the Start Program Number value disappears and the Program Number Running value appears. The Program Running Number is a read only value just to give the operator and understanding of which program is operating. To change the Program that is running the operator will need to End the program to change the Start Program Number. This can only be performed in the Program Set-Up page.

Diagnostics Screen.

The Diagnostics screen is simply a screen to help the operator when problems may occur. For example if the STAR-700 is operating a Program Cycle and there is a cycle of Power, the STAR-700 usually reverts back to SOV mode. However as power loss may occur due to storms and lighting strike and possibly construction work, the disruptive power supply may cause interference with the communication cable and cause the STAR-700 Controller to turn the control actions for Temperature, Humidity and CO2 Off. The Diagnostic screen allows the Authorised operator to turn the Temperature, Humidity and CO2 functions back on again. It also shows the percentage output of each control function. This is a good diagnostic tool if the cabinet is not operating correctly.

MAINTENANCE Apart from the normal levels of cleanliness, the cabinet should be regularly maintained to ensure trouble free operation. A “periodic inspection and maintenance” programme can be arrange in some Australian locations. Lubrication of moving parts is not necessary since all bearings are sealed, but there are one or two essential maintenance chores that should be performed regularly: CLEANING: The internal and external surfaces of the cabinet can be cleaned with a soft damp cloth. Always have in place a program of regular cleaning using a soft damp cloth with a mild solution of soap and water and allow to dry. CARING FOR STAINLESS STEEL Stainless steel is under most conditions extremely resistant to corrosion. This is in part due to the addition of chromium and nickel to the steel and the formation of a durable chromium oxide at the surface during the manufacturing process. There are several chemicals which will attack the surface of stainless steel, plus the lack of oxygen at the surface will cause rusting, corrosion and pitting. Note: Deionised water is particularly corrosive, to minimise, maintain a Neutral pH. CLEANING THE CONDENSER: The refrigeration system has a finned condenser where all of the heat removed from the cabinet is dissipated. To ensure efficient operation of the refrigeration system the condenser face should be kept clean. Failure to do so may result in premature compressor failure and loss of control. The condenser face is accessible from the rear of the cabinet (see figure 1). Use a stiff brush or low pressure air to clean the face. The interval between cleaning will depend on the location of the cabinet, the ambient conditions in which it is operating, and the temperature and humidity conditions that it is trying to control. In dusty hot locations, maintenance should be carried out every 3 months. HUMIDIFIER: The humidifier supplies steam to increase the humidity inside the cabinet. As explained earlier in the section dealing with services, mineral deposits can be left in the humidifier from the constant boiling of water (especially if town water is used). Regular draining of the humidifier will help to keep these deposits to a minimum. To drain the humidifier:

Turn the water supply off.

Open the drain valve and allow the tank to drain. The tank holds about 2.5 litres of water. (See photograph on page 7 for location of drain valve).

Close the drain valve and turn the water back on again. The tank will automatically fill with water and you will have effectively “flushed” the system.

After flushing the tank it will take a while for the water to heat back up again and for the temperature and humidity to stabilise.

You should perform this procedure every 3 months if town water is used, less often if distilled water is used.

WATER FLOW ADJUSTMENT: Water regulator: This valve is used to reduce water pressure and to stop float switch “bounce” when water is injected into the humidifier tank. Needle valve: This valve is designed to adjust the flow of water into the humidifier tank.

If the water pressure regulator or needle valve need to be adjusted use the following procedure below: When mains water is connected to the cabinet:

Pull the water regulator knob towards you and turn it clockwise as far as it can go. This will open the valve fully (there is still enough pressure reduction through the valve even when fully open to reduce “bounce”).

Turn the “lock ring” on the needle valve anti clockwise to allow adjustment of the valve.

With the needle valve fully open (fully anticlockwise), use a flat blade screwdriver to turn the needle valve knob 6 to 8 turns in a clockwise direction. This will allow a flow rate of 1 to 2 litres into the tank, the overflow pipe can cope with this flow rate as long as there are no restrictions in the drain.

Turn the “lock ring” back anticlockwise to stop the needle valve from moving after it has been adjusted.

When the water supply is gravity fed:

Pull the water regulator knob towards you and turn it clockwise as far as it can go. This will open the valve fully (there is still enough pressure reduction through the valve even when fully open to reduce “bounce”).

Turn the “lock ring” on the needle valve anti clockwise to allow adjustment of the valve.

Make sure that the needle valve is fully open (fully anticlockwise) to ensure no restriction to water flow.

Turn the “lock ring” back anticlockwise to stop the needle valve from moving after it has been adjusted.

Note: Both the needle valve and pressure regulator are factory set for a gravity fed water supply.
