Domestic Hot Water (DHW) Storage Tank and Buffer Tank Installation
The DHW and Buffer tanks may be installed inside or outside.
Both tanks must stand vertically on a concrete plinth or firm structure that will support its weight
when full of water and not lean or be prone to fall over during its service life.
The DHW tank should be installed in accordance with Australian StandardAS/NZS3500.4 and
any local or other relevant Government regulations. It is best to install the DHW tank as close as
possible to the hot water outlet that has the greatest usage, such as the kitchen.
Some building codes require a seismic restraint. Consider using stainless steel bands to secure
the tank against the wall.
3.5. When filling the DHW tank, open the hot water taps in the laundry and kitchen to purge air from
the water lines.
3.6.When filling the Buffer Tank, use pure rain water with mould inhibitor, add Glycol if prone to
freezing conditions, and water pH should ideally be at 7.0.
3.7. An expansion tank amd bleeder valve must be included in the hydronic closed loop to allow the
heated water to expand and air to be easily purged from the system.

9. Trial operation by qualified installer
9.1 Pre-start-up checks:
· Check the whole pipe system. Ensure the water volume in the system is full and the air is
exhausted completely. Check whether the water valves are open throughout the system.
· Check the thermal insulation of the pipe work, make sure relevant pipes are appropriat-
ely lagged.
· Check the power supply and distribution system. Check whether the power supply volta-
ge is normal, the power distribution accessory screws are tight, supply power complies
with the wiring diagram and outdoor unit specifications and the wiring is properly grounded.
· Check the air cooled water chiller. Make sure all screws are tight. Check that the signal
indicator light (green) of the outdoor unit control panel is illuminated normally and the fault
indicating lamp (red) is illuminated.
· Connect pressure gauges to the suction Schrader valves in preparation for checking the
refrigerant pressure during operation. Disconnect them when testing is satisfactory.
9.2 Trial operation
· Press on/off on the remote controller, the water pump and fan should start immediately.
The compressor should start shortly after. Observe and determine if there is any abnormal
sound during operation. Stop to check the unit if there is abnormal sound. The outdoor unit
should continue to run only when there is no abnormal sound.
· Check whether the cooling system pressure is normal.
· Check whether the input power and current of the unit are within the parameters set out
in this manual. If not, stop the outdoor unit and check it.
· Observe whether the outlet water temperature is normal.
9.3 The parameters of the remote controller have been pre-set at the factory. We
recommend that you leave these parameters as set.

Cooling mode
Hot water mode, the temperature on the left side of the wire controller is the set
temperature of hot water tank, and on the right side is the actual temperature of
the hot water tank.
Air conditioning mode, the temperature on the left side of the wire controller is the
set temperature of water inlet (heating or cooling), and on the right side is the actual
temperature of water inlet.
Hot water mode and air conditioning mode, the unit default priority is hot water mode.
Therefore the unit will run in hot water mode first, and the number on the left side of the
wire controller is the set temperature of hot water tank, and on the right side is
the actual temperature of the hot water tank. When the hot water tank temperature
reaches the set temperature, the unit will run in air conditioning mode automatically.
This moment the temperature on the left side of the wire controller is the set temperature
of water inlet (heating or cooling), and on the right side is the actual temperature of
the water inlet.
3.3 Modify the set temperature
Under the hot water mode, press button and button to modify the set temperature of the hot water.
Under the air conditioning mode, press button and button to modify the set temperature of the
water inlet.
Under the hot water and air conditioning mode, press button and button to modify the set
temperature of the current operating mode. If the unit is running in hot water mode, and you want to
modify the set temperature of water inlet (heating or cooling), you can follow the steps below.
