INSTALLATION

Assemble Pump and Motor:
Ensure key stock is in place on the motor's shaft. Place the pump's hollow shaft keyway in line with the key stock on the motor and slide the pump onto the shaft. Once the pump is flush with the motor turn it until the pump is level and the bolt holes line up with the holes on the motor. Thread the bolts into place and tighten in a diagonal pattern (see figure 1), make sure to use washers to avoid the bolt heads damaging the flange. Check that pump is filled with oil up to half way point on sight glass (see figure 2) and change the shipping cap for the vented oil cap tightened by hand and not with a wrench (see figure 3).

Figure 1 Figure 2 Figure 3

Attaching Unloader Valve:
Attach unloader valve to pump using the two banjo bolts with the pressure adjuster facing upward, ensure the 2 O-rings are in place at each end of the bolts (see figure 4 & 5). Ensure that you tighten the bolts at the same time so it stays aligned. The unloader valve comes with an inlet filter/mesh screen and quick connect female socket. Using thread tape, install the filer to the inlet and the socket to the outlet.

Mounting Wall Mount Frame:
Mount wall mount frame to concrete wall with the provided Concrete Sleeve Anchors. If the wall/structure is not concrete then use the appropriate heavy duty mounting bolts that can hold the total weight of the pressure washer. Use the wall mount frame as a template for the bolt locations (see figure 6,highlighted in red)

Figure 6

Mount Pressure Washer:
Lift the pressure washer onto the frame and place the bolts through the holes of the motor and frame using the holes in Figure 7 & 8 highlighted in red. You can use the two provided nuts & bolts or you can use any bolts that can fit through the holes. Be sure to have at least 1 washer in between the bolt had and motor as well as between the nut and frame. This will avoid causing damage to the parts and allow for a more secure hold.

Connecting Power:

The Remote Control module will have 2 power cord for power in & power out. Power in is the power cord with bare wires and power out is the cord with rings on the wires (see figure 9).

The power cable with the set of rings are to be connected directly into the motor via the grommet located on the top of the motor. The ground ring is to be connected to the ground screw and the two hot wires connected one on each terminal bridge underneath the nut (see figure 10).
When connecting the control box to your to your power source it will be specific to your facility, either hardwired or by installing a plug for your outlet (plug not included).

Make sure to reference the above system requirements prior to installation.

Remote-Control Power Cords:
Brown = Hot Blue = Hot Yellow/Green = Ground

Connecting Water:
Start by connecting the inlet garden hose (not included) to pump's inlet filter with mesh screen (see figure 11). Attach the accessories including high pressure hose, spray gun w/ built-in sensor, quick connect nozzle and other compatible parts to the outlet of the pump beginning with the high pressure hose (see figure 11)
Make sure water is running through the system prior to turning on the pressure washer to purge the lines of air. Avoid running the pressure washer without water at any time.

Figure 11

Operation:
Now that all is connected to power and water, hold the trigger down to let water flow out of the end, press the "ON" button on the RC Module and the pressure washer will power on. You will now have high pressure flowing from the end of the nozzle, the pressure is adjusted with the unloader valve/pressure regulator by turning the black knob counter clockwise (-) or clockwise (+) as shown on figure 12. DO NOT EXCEED THE PUMP'S RATED PRESSURE.

Figure 12

How does the Remote-Control Module work?

The Remote-Control (RC) automatic start/stop operates using a specially designed trigger to emit a wireless signal indicating that water is flowing and allowing the controller to power the electric motor of the pressure washer.

Trigger Pulled = Motor ON
Trigger Released = Motor OFF

When the trigger is released, the RC controller activates standby mode (indicated by the yellow light) which will power down the motor after 5 seconds. The controller is still active until the trigger is pressed again in which it will immediately power the motor on.

If the controller stays in standby mode with not trigger pull for 30 minutes, then the entire system will power down requiring the green "ON" button to be pressed again.

When pressing the "ON" the module powers the motor immediately stays on for 2-3 mins or until first trigger release, then it will go into standby mode. The system assumes that you will be operating the pressure washer and if no trigger pull is sensed then it powers down for the safety of the pump.
