PLUMBING CONNECTIONS

PLUMBING CONNECTIONS
COLD WATER SUPPLY OUTLET
• The cold water supply connection uses a G 3/4 female thread.
• To connect the cold water supply, use a G 3/4 socket.
• The cold water supply outlet can also serve as a drainage point for
emptying the system.
HOT WATER CONNECTION
• The hot water supply connection also uses a G 3/4 female thread.
• Connect the hot water supply using a G 3/4 socket.
• To ensure thermal e ciency, insulate all hot water lines and
connections with a minimum 13mm closed-cell insulation.
• All hot water supply components must be made of copper.
CONDENSATE DRAIN
• When heat is extracted from the atmosphere through evaporator
coils, it generates condensation in the form of water. In places with
higher humidity, this condensation occurs at a faster rate.
• To collect the water by-product, a condensate tray is placed at the
base of the heat pump. Any surplus water from this tray is chan-
neled through the condensate drain.
• The system comes with a pre-installed condensate drain connection
elbow. It is essential to route the condensate into the nearest storm
water drain using a drainage pipe. Failing to do so could lead to
issues like termite attraction and the growth of algae and moss.

10 Isolation switch (hardwired into 10 amp circuit)
* Supplied with system
• Ensure that the condensate line is free of kinks, and since the water
relies on gravity for flow, it should only run downward to facilitate
unobstructed water flow.
PRESSURE & TEMPERATURE RELIEF TPR VALVE
• The system comes with a TPR (Temperature and Pressure Relief)
valve that matches the water heater tank's pressure rating. If the
TPR valve is missing, please get in touch with your supplier.
The valve is rated with a capacity of 850kPa, 10kW, and a set
temperature range of 93-99°C.
• Install the provided TPR valve at Point 4, as indicated above.
• Ensure that the TPR valve is insulated with a minimum 13mm
closed-cell insulation to minimise heat loss.
• The TPR should be positioned in a way that the drain line always
points downward, and the discharge point remains open to the
atmosphere.
• When connecting a discharge pipe to the pressure relief valve,
make sure it runs continuously downward and is placed in a frost-
free environment. Do not connect any pressure relief device to the
condensate drain pipe, as water may drip from the pressure relief
device's discharge pipe. This pipe should always be left open to
the atmosphere. Additionally, regularly operate the pressure relief
device to remove lime deposits and confirm it is not blocked.
