PLUMBING CONNECTIONS
STORAGE TANK INSTALLATION
Install and connect the storage tank to the
household water reticulation system as per
local plumbing regulations and codes.
Install a condensation drain line in a
continuous fall away from the heat pump
to a safe and legal point of discharge.
Usually this would be a garden bed or
similar location.
PRESSURE & TEMPERATURE
RELIEF VALVE
The Pressure & Temperature relief valve is
supplied loose with the water heater. The
valve rating is:
• 250 Model - 1000kPa
The relief valve must be installed directly
into the top socket marked “RELIEF
VALVE”. The drain line from this valve
must run in a continuously downward
direction with the discharge end left permanently open to atmosphere. The
Pressure & Temperature Relief Valve supplied with the water heater is not
intended to enable connection of the water heater to supplementary energy
sources such as solar panels or slow combustion stoves (refer AS/NZS
3500.4.2 for guidance on these types of installations)
WARNING: A separate drain line must be run for this relief valve. It is not
permitted to couple drain lines from relief valves into a single common drain
line.
COLD WATER CONNECTION
An approved isolating valve, approved non-return valve, line strainer (optional
but recommended), and union must be fitted between the supply main and the
RP¾/20 socket in the water heater. All fittings must be approved by the
relevant installation Authority.
Note for S.A. and W.A.: It is a state requirement that a pressure relief valve
be fitted on the cold water supply line between the non return valve and the
water heater.
