Option 1: In-Line Pressure Switch Fitted With In-Line Electric Pump
Step 1 Disconnect power supply at the isolator switch.
Step 2 Open one cold tap fully.
Step 3 Ensure that the storage tank is fi lled to a level higher than the pump.
Step 4 Turn the power back on at the isolator switch and close the tap once water is running.
Option 2: In-Line Pressure Switch Fitted With Internal Submersible Pump
Step 1 Ensure that there is no air trapped in the pump. Air is released by gently shaking the pump under water while the pump is in the water tank is switched off .
Trapped air in the submersible will not allow the pump to prime.
Option 3: In-Line Pressure Switch Fitted With External Submersible Pump
Step 1 The pump must be placed in the water before connecting to the side of the vehicle.
Please note: At normal fl ow rates the pump should operate continuously - but at low rates the pressure switch will cycle on and off to maintain back pressure in the
pipework.
Please note: When battery voltage is stable, the pump will produce steady water fl ow. If battery voltage decreases or increases water fl ow will be intermittent and the
pressure switch will turn on and off to maintain pressure in pipework.
Whale recommends regular inspection with maintenance and replacement of components as necessary.
Replacement components are available (Whale Part Number: AK7209).
Setting the Pressure Switch
Your pressure switch is factory set and should not normally require adjustment. However, adjustment may be required if the power supply voltage has varied from the
previous setting, either due to battery drainage or higher voltage being supplied when the battery charger is operating. In the event that your pump doesn't switch off
when you close the taps, or it pulses on and off rapidly when the taps are fully open, follow these guidelines to re-adjust the pressure switch setting.
Step 1 Ensure the system, (including the Water Heater, if installed) is full of water and all taps are closed.
Step 2 Tighten the adjusting screw clockwise until the pump comes on (see Fig. 2).
Step 3 Open any tap until you have a smooth fl ow of water, then close the tap.
Step 4 Return to the pressure switch and turn the pressure switch adjustment screw slowly anti-clockwise until the pump has stopped. Turn the adjustment screw a
further half turn (180 degrees) anti-clockwise.
Step 5 Check for correct operation by opening and closing all taps individually. The pump should turn on when the cold tap is opened and switch off immediately when
the cold tap is closed. There will normally be some pulsations at low fl ows. Please note: The hot side (if applicable) may take up to 10 seconds to react.
Three Golden Rules:
1. Never allow the pump to run dry.
2. Never allow the pump to run continuously for more than 15 minutes.
3. The pump assembly must be unplugged before putting the pump back into the refi lled water container.
