HEAT PUMP AND TANK ASSEMBLY
25
22.
Heat Pump Circuit:
Install the heat pump circuit flow and return pipes
between the heat pump module and the heat pump storage tank.
The pipe work between the storage tank and the heat pump module must
be fully insulated with closed cell polymer insulation or similar of a
minimum thickness of 13 mm. Thicker insulation may be required to
comply with the requirements of AS/NZS 3500.4. The insulation must be
weatherproof and UV resistant if exposed. The insulation must be fitted up
to the connections on both the storage tank and the heat pump module.
All compression fittings must use brass or copper olives.
Either DN15 copper pipe or
½” cross linked polyethylene (PEX) pipe
suitably rated for use with a hot water supply and pressures may be used.
Connect one end of the hot water flow pipe to
the ½” x ½” hex nipple
on the non return and air bleed valve assembly at the heat pump
storage
tank, using a ½” compression nut and olive provided.
Connect the other end of the hot water flow pipe to the flexible
braided hose connection, marked with a red collar, at the heat pump
module. A ½” male tube bush is provided for use with copper pipe.
Connect one end of the cold water return pipe to the ¾” x ½” hex
nipple at the heat pump cold return connection on the heat pump
storage
tank, using a ½” compression nut and olive provided.
Connect the other end of the pipe work to the flexible braided hose
connection, marked with a blue collar, at the heat pump module. A
½” male tube bush is provided for use with copper pipe.
Attach the insulated pipe work to the wall using pipe clips or saddles.
Slit the 150 mm x 35 mm diameter insulation provided and insulate
the non return and air bleed valve assembly, securing with the two
cable ties provided.
Ensure the slit of the insulation is on the underside of the assembly
and the air bleed valve spigot is accessible.
