Filling with water and dispelling air from the system
At this stage the wiring to the hot water system should either
be disconnected at the switchboard or have the power
isolated to it (off). Once all plumbing connections have been
made to the hot water system, it will need to be filled with
water and pressurized in order to check for leaks and to
dispel air from the system.
Activate the lever on the relief valve located on the
storage tank.

Turn on the water supply to the premises and open the
isolation valve located on the inlet piping to the storage tank.
Water should begin flowing into the hot water system and
air will be dispelled from the relief valve piping. When water
begins flowing from the relief valve piping de-activate the
lever and wait for the hot water system to pressurise. Check
for any leaks in the hot water system and fix them as required.
Open the air bleed valve located on the circulating water
outlet connection of the heat pump. Wait until water is
flowing freely out of the air bleed valve and then close it. The
heat pump should now be primed with water.
