TEMPERING VALVE
1. The systems are automatically programmed to produce hot water
in excess of 50°C. As such, in accordance with AS/NZS3500, it is
mandatory that a Tempering Valve is installed.
2. We recommend a high performance, or solar rated tempering valve
is used to ensure a more accurate hot water delivery temperature.
3. Your old hot water system may not have had a tempering valve
installed before and therefore you will notice a change in the
temperature of the hot water. This is normal and required under
new legislation. Should you have any concerns, please contact
your installer.
SELECTION OF THE WATER PIPES
Model No.
Inlet
Outlet
EE-HWS-SSHP-200
15mm
15mm
1. The pipe press and flow rate should be calculated before
the diameter selection, the range of pressure drop is
0.3 kgf/cm
2
- 0.5 kgf/cm
2
(3m - 5m) the range of head pipe
flow rate is 1.2m/s - 2.5m/s.
2. The hydraulic calculation should be made after the selection of
pipe diameter, if the resistance is more than pump head, then
need to choose a more powerful pump, or choose a bigger pipe.
WATER QUALITY
1. Poor water quality will produce more scale and sand, so this type
of water should be filtered.
2. The water quality should be analyzed before system running, to
measure the PH value, conductivity, Chloride ion concentration
and sulphate ion concentration.
3. Recommended filter meshes is approximately 40 meshes.
4. The acceptable water quality standard is showed as below table.

PLUMBING CONNECTION
PLUMBING CONNECTIONS
COLD WATER SUPPLY OUTLET
1. The cold water supply connection is a 20mm female thread.
2. The cold water supply should be connected to a 20mm socket.
3. The cold water supply outlet can also act as a drainage point
for emptying the system.
HOT WATER CONNECTION
1. The hot water supply connection is a 20mm female thread.
2. The hot water supply should be connected to a 20mm socket.
3. To ensure thermal efficiency all hot water lines and connections
must be insulated with a minimum 13mm closed cell insulation.
4. All hot water supply parts must be constructed from copper.
CONDENSATION DRAINAGE
1. The process of heat extraction from the atmosphere through
evaporator coils results in the production of water in the form of
condensation. More humid environments will produce higher rates
of condensation.
2. To collect this water by-product a condensation tray is located at
the bottom of the heat pump. Overflow from this tray flows out
through the condensation drain.
3. The system comes with a pre-installed condensation drainage con-
nection elbow. Condensation can be drained to the nearest storm
water via a drainage pipe. If not drained properly, the condensation
will attract termites as well produce algae and moss growth.
4. The condensation line is gravity fed and should run downwards
and be free of kinks to ensure the free flow of water.
TEMPERATURE & PRESSURE RELIEF (TPR) VALVE
1. This system is supplied with a loose TPR valve appropriate to
the pressure rating of the water heater tank. If the TPR valve is
missing please contact your supplier. The valve rated capacity:
850kPa; 10kW; Set temperature: 93 - 99°C.
2. The supplied TPR valve must be installed as per the water tank
schematic Connection Dimensions and Components under the
socket marked "RELIEF VALVE".
3. The TPR valve must be insulated with a minimum 13mm closed
coupled insulation, to minimise heat lost.
4. The TPR valve must be installed so that the drain line is facing
downwards at all times with the discharge point remaining open
to the atmosphere.
5. A discharge pipe connected to the pressure relief device is to be
installed in a continuously downward direction and in a frost-free
environment. Do not connect any pressure-relief device to the
condensation drain pipe. The water may drip from the discharge
pipe of the pressure-relief device. This pipe must be left open to
the atmosphere. The pressure-relief device is to be operated
regularly to remove lime deposits and to ensure it is not blocked.
