Main Pump Installation (continued)
Hose reel connection
: If equipped with a hose reel, route the high-pressure pump hose behind the unit and connect to the fitting
on the hose reel swivel. Use several wraps of Teflon tape on threaded fitting.
GFCI power cord
: Route the GFCI power cord out the back of the pump unit and connect it to the dedicated power receptacle.
Cover installation
•
Install the four cover mounting screws into the side of the frame just far enough to support the cover while the cover is positioned
into place.
•
Position the cover over the unit taking care not to damage the chemical metering knobs or the ON/OFF switch.
•
Remove the two rear cover mount screws and lower the cover into position then replace the screws through the holes in the cover.
•
Remove the two front cover mount screws and lower the cover into position then replace the screws through the holes in the cover.
Ensure that the large washer inside the cover captures the top of the chemical selector mount bracket.
Accessory Installation
Water filter:
Install the water filter assembly on the wall within reach of the 6-foot hoses to the pump and the water supply hose bib.
Connect the braided hose from the pump to the filter fitting labeled "OUT". Connect the hose supplied with the filter to the hose
bib and to the filter fitting labeled "IN".
Chemical baskets:
Install the chemical baskets below or beside the pump unit within reach of the chemical pickup tubes. Locating
the chemical supply at or near pump level will enhance the chemical control function.
Spray gun hanger
: Attach the spray gun hanger to the side of the wall-mount bracket at a convenient location using the self-
drilling/self-tapping screws provided with the gun hanger.
Functional Test
Functional test the unit upon completion of the pump installation, to ensure that it has been installed properly and that there are
no leaks or malfunctions.
NOTE:
Set the ON/OFF switch to the "OFF" position before connecting the power cord to the receptacle.
Ensure the water supply hose is connected to the water supply bibb and the hose bibb valve is fully open.
Circuit Breaker (main):
Set the circuit breaker in the main panel to the on position.
GFCI:
Connect the unit GFCI power cord to the dedicated receptacle and press the "RESET" button on the GFCI. Press the "TEST" button
on the GFCI and verify that the GFCI trips to interrupt power to the unit. Press the "RESET" button and verify that the GFCI resets.
Hoses and spray gun:
The hose may be permanently attached to the wall-mounted hose reel or connected by a quick disconnect
fitting on the front underside of the pump unit. Connect the spray gun to the end of the hose. Direct the spray gun away from
persons or objects and ensure the trigger is in the released position prior to turning the machine ON.
ON/OFF:
Grasp the spray gun firmly and set the ON/OFF switch to "ON". The pump should be heard
to operate. The pressure gauge will momentarily show a high-pressure spike and then drop back to
near zero PSI. The pump will only show pressure on the gauge when the spray gun is in operation.
Low/high-pressure:
Position the spray gun to operate it on low-pressure and squeeze the spray
gun trigger. Note that the output is a low-pressure stream and that the pressure gauge indicates a
pressure near or below 400 PSI. Position the spray gun to operate it on high-pressure and squeeze
the spray gun trigger. Note that the output is a high-pressure stream and that the pressure gauge
indicates a pressure approximately 50 PSI below the pressure shown on the Maximum Pressure
label on the front of the pump.
Chemical injection:
While operating the spray gun on low pressure, set the chemical selector
valve to select one of the chemicals. Note that chemical is drawn up the chemical pick-up tubes
and is dispensed with the low-pressure output. Several seconds may be required for the chemical
to appear at the output. Repeat for the second chemical selector if so equipped. Adjust both
chemical selectors to FLUSH and operate the spray gun on low pressure until the spray output is
free of chemical. Set both chemical selectors to "OFF". Set the ON/OFF switch to "OFF". Squeeze
the spray gun trigger to release pressure. Disconnect and store all equipment.
