6 Installation

6.1 Safety during assembly

WARNING! Risk of injury due to improper assembly! Improper assembly leads to serious personal injuries and property damages. Therefore: - Assembly and startup must take place by an autho-

rised heating and/or air conditioning professional. - Provide sufficient installation clearance before be-

ginning with the work. - Be careful with open components with sharp edges.



activities and secure against being turned on again.

6.2 Requirements on the erection location of the heat pump

Before doing the installation, make sure that the erection location meets the following requirements: - Operating temperature +5 °C to +30� - Dry, frost-proof, good air supply and ventilation - No heavy dust build-up - No high humidity - No air pollution through halogenated hydrocarbons (e.g. in sol-

vents, adhesives, spray cans) - No sulphur compounds - No vibrations and shocks - Stable, smooth and horizontal surface

NOTE! In case of existing systems, a dirt filter must be in-stalled on the heating side to protect the condenser.

Systems with above average temperature loads also require consultation with MHG Heiztechnik.

ThermSelect® 6. Assembly

37/100

WARNING! Risk of life through fire! Easily flammable materials or liquids can catch fire. Therefore: - Do not use or store explosive or easily flammable

substances (i.e. fuel, paints, paper, wood) in the area where the device is installed.

- Do not dry or store laundry or clothes in the area where the device is installed.

- Do not operate device in explosive atmosphere un-der any circumstances.

The following aspects must be taken into consideration already dur-ing the planning of the system, in addition to proper dimensioning: - Future location of the heat pump under the aspect of sound

transmission through air and structure-borne sound. The acoustics in the erection rooms with reverberating walls can increase the operating sound significantly. Countermeasure: acoustic insulation on one of the opposite wall or ceiling surfaces.

- To reduce the structure-borne sound transmission, create a sepa-rate pedestal (e.g. heavy concrete) in mounted in floating fashion (e.g. on rubber).

- A pedestal is recommended for easier maintenance and care.

NOTE! MHG Heiztechnik recommends the installation of an oil sump-pump especially if the condenser is located shut off in a room for several hours (below 12 °C) and it becomes colder than the evaporator. This condition can occur especially in combination with special so-lar systems.

NOTE! Thorough planning with adequately dimensioned heat source is especially important for reasons of operational reliability and improved working output.


38/100

Planning information for brine op-eration

The heat source for operation as a brine/water heat pump (horizon-tal absorber or vertical heating elements) must be configured in ac-cordance with the cooling capacity specified in the technical data. With the ThermSelect® version, the cooling capacity to be provided by the heat source can be reduced by up to 25%, as the source is not fully utilised over the entire heating period. With the ThermSelect® Pro version, the cooling capacity to be pro-vided by the heat source can be reduced by up to 50%, as the brine evaporator is exclusively operated in parallel with the air evaporator with outdoor temperatures of below approx. 5°C and the source is therefore utilised to a minor extent.

CAUTION! Freezing of the heat source due to incorrect operat-ing setting! Heat source becomes unusable for a long period of time. Therefore: - With this version, it is compulsory to exclusively

operate the brine evaporator in parallel with the air evaporator.

- A changeover to alternative mode, i.e. exclusive operation as a brine/water heat pump, overloads the heat source.

CAUTION! Freezing of the heat source due to incorrect dimen-sioning (overload)! Heat source becomes unusable for a long period of time. Therefore: - In case of doubt regarding the efficiency of the sur-

face, a geothermal response test must be carried out by an appropriate professional.

CAUTION! Damage to devices through freezing! The plate heat exchanger is destroyed on the source side, if the brine freezes. Therefore: - Monitor flow with safety devices (flow switch, pres-

sure switch). - The safety devices must be installed on site. The

regulations of the responsible authorities must be complied with.

Furthermore, dirt catchers, bubble separators and a rinsing device must be envisaged.

NOTE! Warranty becomes void if this information is disre-garded and damages can be traced to one of the listed causes.


39/100

Application limits Heating water 20-55°C with refrigerant R 407 C

Installation clearances

Minimum clearances according to Fig. 3 are to be complied with, so that all work (assembly, startup, maintenance) can be carried out unhindered. - Observe the lateral clearance to the heat pump (min. 20 cm) to al-

low access for service and inspection.

6.3 Assembly tools The assembly and maintenance of the heating system requires standard tools from the field of heating installations, cooling installa-tion technology and water systems installations.

6.4 Installation information

CAUTION! Environmental damage through substances hazard-ous to groundwater! Substances hazardous to groundwater, such as greases, oils, refrigerants, solvent-based cleaning agents and the like, can burden the ground or get in-to the sewage system. Therefore: - These substances must be collected, stored and

transported in suitable containers and be disposed off.

The regulations of the heating and plumbing trade (DVGW, DIN, etc.) and of electrotechnics (potential equalization, utility company connection conditions, DIN, VDE, etc.) must be followed in particu-lar.


40/100

Transport NOTE! The heat pump may only be transported standing and never horizontally.

The heat pump is delivered standing on a wooden pallet. It can be transported on the pallet to the installation site. The heat pump can also be transported by 2 persons with carrying straps or transport cart.

CAUTION! Device damage through improper handling! The copper pipes can be easily bent! Therefore: - Do not hold on to the insulated pipe (hot gas line)! - Apply force only to the base plate or the frame!

Refrigerant

The safety datasheet concerning refrigerant R 407 C is available for download at www.mhg.de\Download\Sicherheitsdatenblätter.

NOTE! in case of emergencies, ring the telephone number below: +44(0)208 762 83 22 [CareChem 24] (Europe)

WARNING! Danger to life through lack of oxygen! Vapours of the refrigerants R 407 C are heavier than air and may cause suffocation by displacing oxygen. Therefore: - Exercise special caution when entering lower lying

closed rooms. - Work on the refrigerant circulation may only be per-


- Do not smoke when handling refrigerant as its products of decomposition in the lit cigarette act as an irritant and a poison!




41/100

NOTE! For operators of equipment containing 3kg or more of refrigerant the following duties of documentation apply: - Amount and type of refrigerant - Any amounts of refrigerant refills - Any amounts of refrigerant retrieved during startup,

maintenance or final disposal - Details identifying the company or technical per-

sonnel that carried out the installation, startup, or any maintenance work

- Dates and results of all inspections The recorded information must be presented to the relevant authorities and the commission upon re-quest.

Welding work

NOTE! If any welding work is scheduled on the refrigerant line, a protective gas (i.e. nitrogen) will need to be passed through the pipe in order to prevent scale formation. Scale and other contamination impair the proper operation and lead to faults.

Split evaporator assembly



- The location of the evaporator must always be higher than the

heat pump unit (on slopes, pay attention to laying of the cooling line).

NOTE! Always install the split evaporator in flow direction parallel to the property boundary (not towards the neighbouring plot) in order to reduce noise transmis-sion to neighbouring properties.

NOTE! Ensure that no plants or objects are located in flow direction in order to guarantee efficient operation.


42/100

CAUTION! Device damage due to improper installation of cool-ing lines or improper positioning of the evaporator. Mechanical damage to the device can occur due to insufficient lubrication. Therefore: - Dimensioning and installation of cooling lines must

be carried out by technicians authorised by MHG. - The length of the cooling line may not exceed 15m

single distance. - The rise of the cooling line from the split evaporator

to the heat pump must not exceed 1.5 m. - The line dimensions are matched exactly to the capacity of the

heat pump (line length between heat pump and split evaporator 20 m). Altered line routing and clearances between heat pump and split evaporator must be agreed upon with MHG. Long line paths extend the duration of thawing and are to be avoided.

- The lines are insulated with diffusion-proof material. The gaps of the insulation must be glued.

CAUTION! Environmental damage due to improper assembly of the refrigerant line! Refrigerant and compressor oil can leak! Therefore: - Only use tools that are recommended for used in

the cooling unit: Bending wrench, pipe separator, deburrer and bordering tool

- Take note of bending radius to avoid bending or breaking of pipes.

- To avoid brittle or cracking pipes, do not bend the pipes repeatedly.

- In order to reduce loss of pressure and to ensure return of compressor oil, avoid unnecessary bend-ing of the pipes.

- Use appropriate fastening and insulation during refrigerant line installation.

- Use only non-cutting tools (special pipe cutting tools) to shorten refrigerant lines.


43/100

CAUTION! Device damage through dirt and humidity. Dirt and humidity can enter the pipes when installing them. Therefore: - Make sure that no dirt or humidity enters the pipes

while installing them. - When laying pipelines underground, the laying

depth must be a minimum of 25 cm (on passable routes, a minimum of 50 cm).

- The installation of the pipelines must be carried out using a protective DN 100 pipe.

- The ends of the protective pipe must be sealed and waterproofed.

- The wall duct must be watertight. - Do not let clipping particles get into the refrigerant

line as these cause the destruction of the compres-sor.

NOTE! The heating pump contains refrigerant for a 15m max. length cooling line. Any shortening or lengthening of the line may only be carried out by a certified technician. The refrige-rant dosage must be checked for line lengths exceed-ing 20m, and be adjusted where required (approx. dosage values are available in chap. 5.3).

NOTE! The split evaporator contains a protective gas (nitro-gen) and must be evacuated simultaneously with the refrigerant lines.

NOTE! The technician must check the installation and mountings of the pipe, and establish a proper con-nection with the heating pump and the split evapora-tor.

NOTE! Ball valves must remain shut (delivery condition)!

47/100

Fig. 13: Pre-assemble the enclosure ass seen in the image prior

to installing the hydraulic and cooling lines.

CAUTION! Water damage through condensation or humidity in the air! Extremely low temperatures at the refrigerant lines lead to condensation or humidity in the air and can cause water damage. Therefore: - The heat source lines are lined with diffusion-

resistant insulation which must not be damaged. - Installation-related damage must be closed again in

a diffusion-resistant manner with suitable refrige-rant pipelines.

- Contact between heat source lines carrying refrige-rant with ambient air, by ensuring insulation is sealed without any gaps and absolutely diffusion-resistant, must be ensured.

cable gland.


48/100

Connection of split evaporator with heat pump



- Connect the heat pump and the split evaporator with the refrige-

rant lines.

CAUTION! Environmental damage due to improper assembly of the refrigerant line! Refrigerant and compressor oil can leak! Therefore: - Only use tools that are recommended for used in

the cooling unit: Bending wrench, pipe separator, deburrer and bordering tool

- Take note of bending radius to avoid bending or breaking of pipes.

- To avoid brittle or cracking pipes, do not bend the pipes repeatedly.

- In order to reduce loss of pressure and to ensure return of compressor oil, avoid unnecessary bend-ing of the pipes.

- Use appropriate fastening and insulation during refrigerant line installation.

- Use only non-cutting tools (special pipe cutting tools) to shorten refrigerant lines.

NOTE! The heating pump contains refrigerant for a 20 m max. length cooling line. Any shortening or lengthening of the line may only be carried out by a certified technician. The refrige-rant dosage must then be checked accordingly.

NOTE! The technician must check the installation and mountings of the pipe, and establish a proper con-nection with the heating pump and the split evapora-tor.

NOTE! Ball valves must remain shut (delivery condition)!

- Evacuate the suction, liquid and hot-gas lines. To evacuate the

devices, connect to the Schrader valves (s. Fig. 9). - After the evacuation has been completed, open the ball valves to

allow the refrigerant to distribute. The system is operational after the hydraulic and electrical installation has been made.


50/100

6.5 Hydraulic connection

Requirements for the heat transfer liquid

The heat transfer liquid (brine) in the heat source should be set to frost protection of approx. -12°C. This is achieved with a water-glycol mixture with a share of 25% Tyfocor L (available as an acces-sory). The frost protection must be checked using a refractometer (availa-ble as an accessory) or similar testing device.

Requirements on the heating water

To prevent corrosion damage in the heating system, heating water in potable quality must be used under consideration of the require-ments according to VDI guideline 2035 "Preventing damage in warm water heating systems" / SWKI guideline 97-1 "Water quality for heating, steam, refrigeration and air conditioning systems".

CAUTION! Damage to devices/components from contamination! Partial clogging in the heat exchanger can lead to its destruction. Therefore: - For installations in older systems pre-filtration/silt

separation must be installed in order to protect the plate heat exchanger.

NOTE! Do not use any chemical additives!

Fig. 16: Hydraulic connections


51/100

Legend for Fig. 16:


1 Flow heat pump 2 Return heat pump 3 Inlet heat source brine 4 Outlet heat source brine

With the hydraulic connection, it must be ensure that the correct flow directions are adhered to. At the condenser, the in-flow is at the bot-tom (heating water return to heat pump). The temperature spread of 3-4 K at the heat source and 5- 10 K at the heat drop must be maintained under normal operating conditions while observing the application limits. This spread is nor-mally achieved when the volume flows specified in the technical da-ta are observed. In comparison to conventional combustion systems, heat pumps operate with larger mass flows. This results in larger pipe diameters and relevant pump configurations.

CAUTION! Device damage through improper system setup! Water and/or glycol mixture can leak. Therefore: - In the brine system, as well as on the heating side,

safety devices and expansion containers must be installed.


52/100

6.6 Electrical connection

DANGER! Risk to life through electrical current! Contact with live components can cause serious inju-ries. Therefore: - When working on the device, all supply lines must

be without current. - Make sure that all electrical parts are without cur-

rent. - The applicable VDE and utility company regulations

as well as the respective regulations and guidelines of the country of destinations must be complied with.

- The electrical connections must be inspected by a responsible technician before establishing the con-nection with the line supply.

- An external separator (e.g. main switch) must be envisaged for all electrical supply lines to the ma-chine.

- Only operate the heat pump within the implementa-tion frequency (s. chapter 5.3 Type of electricity for compressor) (in Germany 50 Hz).

CAUTION! Interferences through electrical fields! Supply lines (230 V) may interfere with sensor lines (electrical low voltage). Therefore: - Sensor and supply lines may not be routed in the

same cable conduit.

7 Commissioning

7.1 Safety during startup WARNING! Risk of injury through improper operation! Improper operation leads to serious personal injuries or property damages. Therefore: - Installation and assembly must be performed by a

heating systems dealer. - Work on the refrigerant circulation may only be per-


- Carry out all of the operating steps in accordance with the information in these instructions.

- Before starting with the work activities, make sure that electrical and hydraulic lines are shut off and secured against inadvertent opening.

- Use only suitable tools.

7.2 Inspection prior to startup Make sure of the following after proper assembly: - the electrical connection has been correctly installed. - the polarity of the line connection is correct - electrical voltage is applied - the heating system and possibly existing reservoir are correctly

filled and ventilated - the heat source system is correctly filled and ventilated - the correct installation of all required safety devices was made. - proper circulation of the heating water and hot water circuit exists - all refrigerant lines and valves are sealed intact - refrigerant lines are covered with diffusion-resistant insulation,

without any gaps - all attachments, suspensions, etc. are fastened properly and have

been verified as to their proper height

NOTE! After installation and prior to startup of the system, the protective earth resistance and the insulation re-sistance must be tested according to DIN VDE 0701 and DIN VDE 0702 and documented. These tests need to be repeated according to the applicable local time intervals or according to the DIN VDE - regulations, series DIN VDE 0701 and 0702 (repair, restarting, etc.).

7.3 Commissioning

NOTE! The customer / owner of the system must be present when starting up the system. A startup protocol is established on site.

NOTE! For operators of equipment containing 3kg or more of refrigerant, the following duties of documentation apply: - Amount and type of refrigerant - Any amounts of refrigerant refills - Any amounts of refrigerant retrieved during startup,




PRECAUTION! Risk of injury due to refrigerant! Refrigerant leakage damages the environment 100- 24,000 times more than carbon dioxide (CO2). Therefore: - Hermetically sealed systems that contain 6 kg of

refrigerant or more must not exceed a leakage rate of 1%.

CAUTION! Device damage through wrong direction of rotation of the condenser! A reverse run over several hours or days causes se-rious damage with a loss of guarantee. Therefore: - The use of the compressor requires the correct ro-

tational direction to be set and adhered to (clock-wise rotating field).

- When turning in the wrong direction, the condenser works much louder than usual and does not pro-duce any output (compressed gas neck remains cold). A brief reverse run of a few minutes is not harmful.

CAUTION! Device damage through dry pump running. If the brine circuit is not connected or not filled, the pump can be damaged. Therefore: - The device can only be started up with a filled heat-

ing and brine circuit. Refer also to the "Startup order form".

Switching on the device

After proper inspection of the installation, the power connection can be switched on. For this, activate the installed power switch and au-tomatic circuit breaker.

Refrigerant dosage

The quantity of refrigerant is determined during operation by mea-suring and comparing the refrigerant condensation temperature and the heat pump flow temperature. The heat pump / compressor must be activated for min. of 10 min. and a flow temperature of approx. 50°C must be reached before measurement or the results will not be reliable and the amount of refrigerant indicated will not be correct. The difference between both of these temperatures should be be-tween 0 and 3 K (condensation temperature - flow temperature).

Test for leak-tightness

Once operating, the refrigerant circuit must be rechecked for lea-kage using a sensitive leak detection device/substance.

ThermSelect® 9. Troubleshooting

73/100

9 Troubleshooting

9.1 Troubleshooting It is frequently noticeable that the heat pump heating systems are not operating properly because the heating circuit does not have the required volume flow. The consequence of this is the activation of safety devices on the heat pump. In case of insufficient or no flow in the heat exchange on the heating circuit side, this leads to a high-pressure disruption. It cannot be ruled out that the safety temperature limiter will also switch the sys-tem off with insufficient hot water flow. The causes of the listed faults have their origin in the periphery and in the rarest cases, in the heat pump itself. Incorrect settings on the controller can have similar effects. The activation of relevant sen-sors and the signalisation of a fault are for the protection of the sys-tem and are generally not an indication of a defective heat pump.

Faults and their removal

If the heat transfer is suddenly disrupted when the heat pump is running (e.g. due to standstill of circulating heat pump or closed valves), it can (due to the thermal inertia of the system) occur that the high-pressure safety limit switch in the heat pump is activated. The heat pump is thereby shut off and an automatic restart is pre-vented for safety reasons.

NOTE! Reduction of the service life of the high-pressure -safety limit switch, as well as the compressor, through excess wear and tear. Therefore: - If the high-pressure limit switch is activated, check

and rectify the cause. Another possible reason for triggering this high pressure safety limi-ter may also be related to the local conditions of the heat pump's in-stallation site which may necessitate the installation of an oil sump heater (strip heater on the condenser) or a "pump-down function".

Course of action for malfunctions

If electrical errors (e.g. defective sensors) can be ruled out, begin with checking the circulation pump and valves of the heating system and heat source.

NOTE! If all errors can be ruled out on the external system, the cooling cycle of the heat pump must be checked by an authorized technician.

Warranty claim for wearing parts

(See recommendation EHI European Heating Industry, information bulletin 14) The spare parts list also contains "spare parts" that must be re-placed when the device is used as intended within the warranty pe-riod. The warranty periods have been extended by law makers, however, this does not preclude possible wear and tear from operation. It is known that a device may operate up to 8,760 hours a year when used as intended if this is a permanent operation system. According to customary commercial treatment, the costs incurred in these con-ditions are not covered by the warranty obligation or commitment of the manufacturer. The components listed in the spare parts list have been divided into the following categories: 1. Spare parts Spare parts are used for the repair of products

a) Parts are replaced that have not reached the expected ser-vice life although the device was operated as intended.

b) Furthermore, parts that are replaced due to improper opera-tion or unintended use (e.g. wrong burner settings, water flow to low or too high, boiler scale through unsuitable filling water, use of incorrect refrigerant, etc.).


78/100

2. Wearing parts Wearing parts are such parts which must be replaced sever-

al times within the scope of service life while the product is used as intended (e.g. during maintenance).

3. Auxiliary materials Auxiliary materials are required with the repair and mainten-

ance of devices. Typical auxiliary materials are, for example, seals of all kinds,

hemp, lead oxide red or fuses. Auxiliary materials are not subject to any warranty claims, except

the necessary use in the context of replacing parts in the frame-work of an existing warranty claim.

Warranty certificate MHG provides warranty for compliance with explicitly promised properties, for non-defective construction and manufacturing as well as for flawless material in the manner that the parts which have become unusable as a result of such defects or where there usefulness was significantly compromised are delivers as new at their own costs and risk. MHG provides warranty for replaced parts to the same extent as for the original delivery item. The following warranty periods apply for the ThermSelect® heat pump:

- 2 years material warranty on all electrical and other components , as well as on the heat pump function.

The ordering party can only assert warranty claims from MHG if the startup of the delivered item was performed by staff of MHG, companies trained by MHG or a qualified refrigeration company, the order-ing party has observed the MHG regulations of the handling and maintenance of the delivered item, the prescribed inspections were done properly and no spare parts of third-party origin were installed.
