Installation Guide

a) For all grounded, cord-connected appliances:

GROUNDING INSTRUCTIONS
This appliance must be grounded. In the event of malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
If there is any doubt whether the outlet box is properly grounded a qualified electrician must be consulted.

DANGER – Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Check with a qualified electrician or serviceman if the grounding instructions are not completely
understood, or if in doubt as to whether the appliance is properly grounded. Do not modify the plug provided with the appliance – if it will not fit the outlet, have a proper outlet installed by a qualified electrician.
Exception: For products employing date code marking on power supply cord attachment plug blade in accordance with 70.1.19, the instructions above shall be replaced with the following:

DANGER – Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. Check with a qualified electrician or serviceman
if the grounding instructions are not completely understood, or if in doubt as to whether the appliance is properly grounded. Do not modify the plug provided with the appliance – if it will not fit the outlet, have a proper outlet installed by a qualified electrician.
b) For grounded, cord-connected appliances rated less than 15 A and intended for use on a nominal 120 V supply circuit:
This appliance is for use on a nominal 120 V circuit, and has a grounding plug that looks like the plug illustrated in sketch A in Figure 73.1. A temporary adaptor, which looks like the adaptor illustrated in sketches B and C, may be used to connect this plug to a 2-pole receptacle as shown in sketch B if a properly grounded outlet is not available. The temporary adaptor should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adaptor must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever
the adaptor is used, it must be held in place by the metal screw.
c) For grounded, cord-connected appliances other than as mentioned in (b)
To reduce the Risk of Electric Shock, this appliance has a polarized plug. This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.

Connecting the unit

Before the unit can be put into operation Water,
Cleaning products and Electricity must be connected
to the unit.

Connections

2. Pull the outlet to the desired length.
3. Connect the desired nozzle foam (white), rinse (blue).
4. Connecting the nozzle is done by pulling back the quick connector/coupler (Fig. 11). Connect the nozzle by pushing the nozzle into the opening of the quick connector.

NOTE: Make sure the nozzle is “clicked” properly into the coupling, you will hear a small click when the nozzle slips into place.

Testing the Rinse function:
Hold the ball valve/pistol over sink for testing.

1. Turn the selector knob on the unit to rinse position.
2. Connect the rinse nozzle to the ball valve/pistol.
3. Open the ball valve/pistol and the pump will start. It may take several seconds for the outlet hose to be filled completely with water.
4. The unit is now rinsing.
5. Close the ball valve/pistol to stop rinsing, the unit will automatically stop a few seconds after the ball valve/pistol is closed.

Testing the Foam function:
Hold the ball valve/pistol over sink for testing.

1. Turn the selector knob on the unit to foam position.
2. Connect the foam nozzle to the ball valve/pistol.
3. Open the ball valve/pistol. First the pump and then the compressor will start. It will take about 10-15 seconds for the outlet hose to be filled completely with foam.
4. The unit is now foaming.
5. Close the ball valve / pistol to stop foaming, the unit will automatically stop, it can take up to 10 – 20 seconds after the Ball valve / Pistol is closed
   before the unit stops.
   • We recommend maximum 20 min. continuous operation of the compressor (foam mode). After 20 min. operation a 20 min break must follow before foam operation is continued.

WARNING:
When opening the ball valve/pistol after the unit has stopped in foam position, a burst of Foam/Air/Water will come out. as the outlet hose is filled with foam. The burst will disappear after 3-5 seconds.
Point the ball valve towards the floor when opening.

Testing the Sanitise function:
Hold the ball valve/pistol over sink for testing.

1. Turn the selector knob on the unit to sanitise position.
2. Connect the blue sanitise nozzle to the ball valve/ pistol.
3. Open the ball valve/pistol and the pump will start. It may take several seconds for the outlet hose to be filled completely with sanitiser.
4. The unit is now sanitising.
5. Close the ball valve/pistol to stop sanitising. The unit will automatically stop a few seconds after the ball valve/pistol is closed.

If all 3 tests perform correctly the unit is ready for use.

Checking the unit for leaks

1. Remove the cover by loosening the 4 screws on both sides of the unit using a 4mm Allen key.
2. Check all connections and hoses for leaks.
3. Once you have determined that there are no leaks, remount the cover and tighten the 4 screws.
