Priming the System
i. Place pump into the container, submerging pump.
ii. Place pump plug assembly into inlet socket, close lid ensuring plug
assembly shoulder locates into lid recess.
iii. Open all kitchen and bathroom taps to release air from system.
iv. Adjust dust cover over opening in container (please note dust cover
should not be secured to water container as air must be allowed to
enter container to replace water being pumped out).
v. Switch on 12 volt supply at main panel (isolator switch).
vi. Water will flow from open taps expelling any trapped air within a
few seconds.
vii. Turn off tap, the system is now ready for use.
Warning: Care should be taken when turning on any of the hot taps
after the water heater has been switched on as steam can spurt from the
tap whilst the hot water system is filling.
Pressure switch
Operation
The pressure switch detects the opening or closing of any tap in the system
and switches the pump on or off accordingly.
At normal flow rate the pump should operate continuously - but at low
flow rates the pressure switch will cycle on and off to maintain back
pressure in the pipework.
