THE WATER SYSTEM
Water Supply
All models are supplied with a 12 volt submersible pump, controlled by a
pressure switch. The water inlet is located in the off-side exterior wall,
protected by a lift up lid.
The Submersible Pump
1. Operation
i. Raise watermaster housing lid, (it is advisable to liberally lubricate
inlet nipple ‘O’ rings with vegetable oil or Vaseline, this reduces the
friction between ‘O’ rings and plastic surface of the pump plug
assembly).
ii. Place pump into a full water container ensuring the pump is fully
submerged. (This helps to release any trapped air held within the
pump assembly).
iii. Plug the pump assembly into socket inserting plug shoulder into the
hinged lid recess. Lever lid to lock the plug assembly in place. (This
ensures the plug assembly is secure avoiding system leakage and air
getting into the system).
