Adjusting Pressure Switch
If the battery voltage is not constant, cycling may occur even at higher
flow rates. This can be minimised by adjusting the switch’s diaphragm
sensitivity as follows:
i. With the system properly primed, close all taps and showers.
ii. Leave the power supply turned on.
iii. Tighten the adjusting screw (clockwise). The pump should now be
running.
iv. Partly open one cold tap to allow water to flow.
v. Now slowly loosen the adjusting screw until the switch starts to click.
The switch will then be properly adjusted.
Onboard water supply (Senator)
This is located under the chest of drawers at the front of the caravan.
Firstly ensure that the over flow pipe is fully tightened into the base of
the water tank. (The overflow pipe is removed to drain the water tank).
This can be accessed by removing the lower drawer from the chest of
drawers, and pulling the bed slat leader board forward. The black
screwcap on the top of the in-board tank can then be taken off by reaching
throught the bed slats. The over flow pipe can then be seen.
To fill, place the submersible pump inside a filled water container before
inserting the hose in the external filler neck. Connect plug to the external
power socket.
Switching the pump switch, located on the control panel, to EXT position
can now fill the tank. When tank is full, water will flow from the overflow
pipe under floor. Alternatively, the tank can be filled direct from the site
supply using a hose.
