OVERVIEWThis manual is intended to provide general guidance for the installation of an SMT Pressure Cleaning System to an experienced equipment installer. Due to the wide variations of building structure and design into which the SMT system may be installed, as well as variations in the optional features of the system itself, it is not intended to be a comprehensive step-by-step installation procedure.

The standard SMT Pressure Cleaning System will include an SMT 2000WCY pump which will be wall mounted utilizing a mating wall mount bracket. The hi-pressure water discharge from the pump will be connected to each of various remote stations with interconnecting hi-pressure. Remote electronic control of the pump is facilitated by interconnecting 24 volt control cable between the pump and remotes. The system includes some cleaning accessories such as a portable hose reel, hi-pressure hose(s), spraygun(s), and an SMT Hummer Jet Sr. parking lot/surface cleaner and other optional equipment.

In all cases the pump and interconnecting hi-pressure lines must be installed such that they are not exposed to freezing temperatures to protect them from freeze damage. Remote stations may be installed surface mounted or recessed into the outside of an exterior wall as long as the plumbing to the remote station is run within the heated area of the building.

The pump must be installed at a location that is accessible for servicing. It should not be installed above any equipment or materials that will be damaged or pose a safety hazard by exposure to water.

Remote stations should be installed at convenient locations throughout the facility. The remote must be securely attached to the building structure to hold it in place as tension will be exerted on the remote station by the hi-pressure hose which will be connected to it during use.

The hi-pressure interconnecting hoses will be run from the pump, to overhead above the ceiling and down inside the walls to the remote station.

Some installation hardware is included. Additional hardware may be required that is not provided by the manufacturer.

The following is a list of typical tools required for installation of an SMT Central Pressure Cleaning System:

• Common hand-tools • 5/8”, 11/16” and assorted combination wrenches • Tubing cutter and tubing bender for 3/8” stainless steel tubing • Cable Cutter, wire stripper, wire terminal-crimper • Drill; drill-bits for masonry and/or wood; hole saws and driver bits • Grinder (hand-held) with masonry blades

Once the location of the pump unit has been established and electrical and water service requirements are available at the site, the pump unit may be installed. Use the appropriate figure as a guide to install the following components. Figure 1 shows a typical pump installation.


SMT 2000WCY SYSTEM COMPONENT IDENTIFICATION

Refer to Figure 2 for the identification of the components of particular interest during installation of the SMT2000WCY Wall Mount Pressure Cleaning System. These components may be referred to during the description of the installation procedures.

FIGURE 2 - SMT 2000WCY System Component Identification


FIGURE 3 - Wall Mount Bracket Installed (SMT 2000WCY)

Refer to Figure 3 for installation of the wall mount bracket. Proper orientation of the Wall Mount Bracket is essential. A decal is attached to the bracket identifying the top of the bracket when properly oriented. If the decal is not present, use the following description of the bracket to identify the top. Note that the top cross-member of the wall mount bracket is toward the back of the frame while the lower cross-member is located toward the front of the frame. This orientation is necessary to install the pump and to keep the pump frame assembly parallel to the wall.

The wall mount bracket must be secured to a wall that will support the weight of the pump - up to 200 pounds. Minimum 48” x 48” x ¾” plywood backing or equivalent is required in/on the wall at the desired height and location. The wall mount bracket will be attached to the wall with minimum ¼” hardware suitable for the wall construction type. Once the Wall Mount Bracket is installed, the Pump Frame Assembly can be mounted to it.

Allowing for the clearances shown in Figure 3 will ensure the unit can be easily installed and fully accessed for preventive maintenance and service.

WALL MOUNT BRACKET INSTALLATION-


Refer to Figure 4. The Pump Frame Assembly is heavy and should be lifted appropriately with lifting equipment or four-man lifting. The Pump Frame Assembly is equipped with u-channel cross-members that will nest over the cross-members of the Wall Mount Bracket previously installed on the wall.

1. Position the Pump Frame Assembly below the Wall Mount Bracket with the u-channel cross-members toward the wall.

2. Lift the Pump Frame Assembly into place so that the two u-channel cross-members of the Pump Frame Assembly nest over the two square tube cross-members of the Wall Mount Bracket. Align the holes in the u-channel cross-members with the holes in the square-tube cross-members of the wall mount bracket.

3. Install 1/4-20 x 1-1/2” bolts through the cross-members at four locations as shown in Figure 3. Install the washers and hex lock nuts to secure the bolts into place.

4. Attach the black water supply hose to the bulkhead fitting on the underside of the float tank support plate. Connect the other end of the water supply hose to the hose bib or to the optional water filter, if included.

5. Loosen one manifold plug on top of the unloader assembly discharge manifold for each remote station that will be connected. The plug will be removed and replaced with a hi-pressure remote station supply hose upon installation of the remote station.

6. Extend the chemical pickup tube down below the pump assembly for insertion into the chemical supply.

7. A qualified electrician may now connect the line power through the power service-disconnect to the Pump Assembly Master Control Panel. Note: The line service must be a dedicated circuit with a GFCI breaker in the main power panel.

Figure 5 shows the Pump Frame Assembly properly installed on the Wall Mount Bracket.

UTILITY SERVICE REQUIREMENTS-

Electrical Requirements:• Dedicated Circuit• 208V, 30 amp, 1 phase, 60Hz• GFCI Breaker in Main Panel• Service Disconnect at the Pump

Water Supply Requirements:• ¾” Garden Hose Bib• Minimum 5 GPM @ minimum 30PSI• Cold Water (maximum 120° F)

WATER SUPPLY FILTER ASSEMBLY INSTALLATION (OPTIONAL EQUIPMENT)- • Mount the water supply filter assembly to the wall below the unit in a location that will allow easy

replacement of the filter element. Note: High torque is sometime required to remove the filter bowl and will place stress on the mounting hardware. Secure the filter mount bracket to backing within the wall with hardware adequate to sustain the high torque required to remove the filter bowl.

• The Filter assembly must be located within the reach of the two six foot hoses from the hose bib supply and the pump input.

• Connect the black hose from the hose bib to the filter input labeled “IN”. • Connect the second black hose between the water filter “OUT “ port to the tank fitting on the underside

of the pump unit.

Remote stations may be installed for either outdoor or indoor use. For outdoor installation, the remote panels will be securely attached to the exterior wall of the facility. For indoor installation, the remote station may be securely attached to any interior wall that will permit easy access and connection of hi-pressure hose. Remote stations are typically installed at a height centered at 48” above the finished floor. Remotes may be installed at any height but recommended height is between 32” to 60” above finished floor (AFF).

The general location of each remote station within a facility was previously identified during the design of the system. The next step is to identify the specific location of the remote in the wall. Exact location can be affected by the type of wall construction and obstructions within the wall and local building codes. Where possible, avoid locations near electrical wiring, outlets and switched as well as other plumbing.

FOR NEW CONSTRUCTION; a single straight 2” PVC electrical conduit with a long sweep elbow should be installed in the wall as a chase within which to run the hi-pressure supply hose and control cable. The PVC conduit should be secured vertically within the wall extending above the finished ceiling, down to just above and aligned with the opening in the wall for the remote station connection. The hose extending from the bottom of the chase, will attach to the rear of the remote station. The top end of the PVC conduit must extend above the interior wall or exit the wall above the ceiling in a position that will allow insertion of the 3/8” high-pressure hose. Install a long sweep elbow at the top of the chase as necessary to exit the wall above the ceiling.

FOR EXISTING FACILITIES; hoses and control cable should be run above the ceiling and down to the rear of the remote station. Where possible install a 2” PVC electrical conduit as a chase as described in the previous paragraph. If a chase is not practical, attempt to run the hose and control cable within the wall without the chase taking care to protect the hose from sharp edges and corners that may chafe and damage the hose. If running within an exterior wall, run hoses on the heated side of the insulation within the wall to protect the line from freezing. In many cases this may require an access panel on the inside wall behind the remote station for connecting the hose and control cable and for future servicing.

If it is not possible to run the hose and control cable within the wall it will be necessary to run the hose and control cable on the surface of the back side of the wall from where the remote is located. Penetrate the wall

FIGURE 10 - SMT 2000WCY Pump ConnectionsHi Pressure Interconnecting Hose Installation

Refer to Figure 10. Hi-pressure water from the pump unit is distributed to the remote stations through 3/8” hi-pressure hose rated for 3000PSI or greater. Each remote station is connected directly to the pump discharge manifold using a dedicated hi-pressure supply hose. The hose must be installed and secured to the building structure so that it is not kinked or in contact with any sharp edges or corners. The hose will flex a small amount with fluctuating pressure and will be damaged if it is allowed to chafe against rough or sharp surfaces.

Low voltage multi-conductor cable is used to interconnect the remote stations to the pump which will provide remote operation of the pump from any remote station location. This low voltage control cable is run along with and typically strapped to the hi-pressure supply hose running to each remote station. This 24 Volt wiring typically does not require enclosure in conduit. Check local code for verification. The control cable may be run simultaneously with the hi-pressure hose by strapping the cable to the hose as it is pulled into place. Leave an extra 12 inches of cable at the remote station end of the hose for connection to the control panel.

HI-PRESSURE INTERCONNECTING HOSE AND CONTROL CABLE INSTALLATION


Your system is supplied with hi-pressure interconnecting hoses of a length suitable for the location and distance of each remote station from the pump. Verify the hose length is sufficient for the location and run path to each remote station. An extra 12 – 18 inches of hose slack at each end will make it easier to connect and service the remote station and the pump.

The control cable may be attached to the hi-pressure hose with electrical tape every few feet and pulled into place simultaneously with the hose. Leave an extra 12 – 18 inches or cable extending beyond the hose ends for ease of connection.

A typical hose installation is to feed the hose into the area above the ceiling beginning at the pump location. Carefully pull the hose along the predetermined path to the remote station while continuing to feed the hose up into the ceiling. Take care while pulling the hi-pressure hose and cable into place that the coverings are not damaged by dragging through pinch points or against sharp edges.

Feed the hose down into the wall to the location of the remote station. If a 2” PVC chase has been installed for this purpose, feed the hose and cable into it until the hose and cable exit through the opening in the wall for the remote station.

Connect the hi-pressure hose to the remote station fitting using several wraps of Teflon tape on the pipe thread of the hose fitting.

Connect the hi-pressure hose to the pump discharge manifold using several wraps of Teflon tape on the pipe thread of the hose fitting.

Attach the hi-pressure hose to the building structure using rubber coated straps, cable-ties or equivalent hardware that will secure the hose in place while protecting the hose from damage. Anchor the hose every two to four feet.

CONTROL CABLE INSTALLATION-

Run the control cable with the hi-pressure hose between the remote station and the pump. Attach the cable to the hose using the cable ties provided.

Connect a six-foot length of control cable into the Master Control Panel upper left corner to the 5-terminal strip using the pink crimp-on terminals shipped on the 5-terminal strip. Connect the control wires of the control cable to the appropriate terminal in accordance with the wiring diagram inside the front cover of the Master Control Panel and Figure 8 in this manual. When properly connected, all the wires connected to the terminal strip will match colors on each terminal.

In the ceiling above the pump, splice all conductors in the remote station cables to the control cable from the Master Control Panel. Match color to color (black to black, red to red, etc.) Match color and connect all colored wires even though only the red, black and green conductors may be used. This will provide the option to switch to one of the other color wires should wires become damaged. Secure each wire nut connector to the wires with electrical tape.

The control cable may have three to six conductor wires. If the cable is a shielded cable, splice the shield drain wires together as well.

At each remote station, connect the control cable to the wire leads of the remote station key switch with the wire nuts provided, matching color to color (black to black, red to red, and green to green). Secure the wire nuts to the wiring with electrical tape.

• Do not turn the key switch on without a hose and spraygun connected to the remote station. Hoses and sprayguns cannot be connected/disconnected when the system is pressurized.

• Squeeze the spraygun trigger to release pressure from the system BEFORE disconnection of hoses and sprayguns.

• If pressure is locked into the system without a spraygun connected, release pressure on the system at the pump by momentarily opening the pressure bleed valve on the pump discharge manifold. Close the pressure bleed valve immediately upon releasing the pressure.

• Ensure the chemical pickup tube is submersed in the chemical supply or a bucket of water to prevent pump cavitation when the remote station key switch is set to SOAP.

TESTING AND OPERATION-

Test and operate the system in accordance with the following instructions.

Preliminary Setup

• Set all Key Switches at each remote station to the OFF position and remove the keys.

• Check the oil level. Verify the oil level is at the middle of the sight glass on the right end of the pump. Add oil as necessary but do not over-fill.

• Submerse the chemical pickup tube into a chemical supply.

• Connect a hose and spraygun to any remote station.
