Installation
Unit installation positioning !
•This appliance requires good air flow through the fin coils for maximum efficiency. Also, hotter outside
air temperature in cooling mode and colder outside air temperature in heating mode will reduce
performance of the unit. Therefore, the hot/cold discharged air in cooling/heating modes from the unit
should not be allowed to return back to the air inlet. !
Please keep enough space around the unit for repairs and maintenance. !
Installation considerations:
•The installation position should have good ventilation.!
•The installed unit should not make extraneous noises or rattling sounds.!
•Try to minimise direct sunlight onto the unit.!
•Water from rain or defrost mode will be discharged through a drain hole in the base plate. 2.5 The
outlet air position should not face into a prevailing wind direction or this will reduce performance
efficiency.!
•Try to site the unit so the outlet air does not discharge directly onto a fence or towards a neighbour.!
•The installation position should not be located next to flammable or explosive materials, or naked
flames.!
•The unit should be protected from oil (such as engine oil in a plant room), salt (such as sea spay or
salty air) and/or sulphides (that may be present in the air from a thermal spring). !
•The unit should ideally be installed on the ground, preferably on a concrete plinth. Alternately, the unit
can be installed on a balcony, ledge or roof provided there is a suitable load-bearing platform in place
capable of supporting the weight of the unit and not transmitting vibration noise. !

•There should be a drainpipe or channel from the unit to take the condensate water.!
•Do not install the control panel in a bathroom because the wet conditions may cause the control panel
to malfunction. !
Side fan type installation space requirements: !
Hot water storage tank and buffer tank installation site selection
•The hot water storage tank and buffer tank can be installed indoors or outdoors.!
•The storage and buffer tanks should be installed on a concrete plinth and comply with local Standard
so the tanks remain upright and cannot fall over.!
•Some building codes require seismic restraint. Consider restraining the storage and buffer tanks with
stainless steel bands. !
The storage tank and buffer tank installation
•Ensure the specification label is visible.!
•A pressure limiting valve must be fitted.!
•A cold water expansion control valve may be fitted.!
•A pressure limiting valve must be fitted to ensure the incoming water is no greater than 500 kPa.!
•A cold water expansion control valve may be required in areas with mineralised water. Check your
local plumbing code or check with your plumber. If required, this should be set at 700 kPa.!
•A pressure and temperature relief valve is supplied with the hot water storage and buffer tanks and is
set at 850 kPa.!
•A tempering valve set at 50 deg C is required by Australian regulations for hot water supply to
bathrooms.!
•A drain must be included to allow full and complete draining of the tank.!
•It is recommended that the hot water outlet pipes are fully insulated with weather proof insulation such
as Armaflex or equivalent.!
•The hot water outlet pipes should be angled down by 15 deg C minimum for the first 250mm after
exiting from the hot water storage or buffer tanks. This will create a heat trap that will avoid any
thermal siphoning from the tanks.!
•Fill the hot water storage tank by opening the hot water taps and opening the cold water inlet valve to
allow air in the water lines to be expelled. Close each hot water tap as the water flow becomes free of
air. Check all pipes for any signs of leaks. Power should not be turned on until the tank is completely
filled with water.!
•Fill the buffer tank and hydronic closed loop system with pure water (eg rainwater) and an inhibitor (eg
Gendex 100ml per 50 litres) to prevent mould. Glycol should be added if there is any likelihood of
freezing conditions. An alkaline treatment to rainwater is recommended to bring the pH level up to 7.0
such as dolomite. Such steps will give the longest life to the components of the hydronic system.
NOTE: Ensure all air is purged. !

Installation of indoor heating and cooling equipment
•Indoor heating and cooling equipment such as fan coils, radiator heating or floor heating, should be
installed in accordance with relevant regulatory requirements, engineering design drawings, and the
manufacturer's installation instructions.!
•Use soft connectors to connect the unit with the indoor heating and cooling equipment. !
•Install condensate water drain pipes to the indoor fan coil units with smooth drainage lines for the
condensate water to flow easily. !
Water pipe connections
•Water pipe material should be heat resistant and rust-proof. This can be stainless steel, copper,
aluminium, hot water PPR pipes, etc according to relevant standards.!
•The choice of pipe size should match the heat pump inlet and outlet with the pipework"
of the system, and follow the relevant standards. !
•The hot water storage and buffer tank drain port and pressure and temperature relief valve should be
installed to allow for proper drainage according to relevant standards. !
•The hot water storage and buffer tank must be installed with an isolating valve to allow for
maintenance. !
•The water pipes should be arranged with smooth bends to reduce pressure loss in the system.!
•The water main inlet should be fitted with a one-way valve and isolating valve, or Duo valve. !
•The water main inlet should be fitted with a water filter (note the Duo valve may have a water filter).!
•The water outlet of the unit should be connected to the solar flow port on the hot water storage tank
with solar return port connected to the water inlet of the unit. !
•The hydronic closed loop of the buffer tank should be connected to a manifold that is in turn
connected to the hydronic flow and return ports of the buffer tank. The buffer tank should be
connected to the unit via 3 way valves in the same way as the hot water storage tank is connected
(refer schematic diagrams in Section IV). !
•After the water flow and return pipes are connected to the hot water storage tank and buffer tank, the
system should be tested at water supply pressure to ensure that the system does not leak. If
satisfactory, then insulate all hot water fittings and complete the installation. 6.11 In order to discharge
all air from the hydronic water circuit, an automatic exhaust valve should be installed at the highest
point. !
•An expansion vessel and automatic stop valve should be installed into the hydronic system and
located indoors in areas with sub zero temperatures to prevent possible cracking of the water pipes
and valves when not in use in the winter.!
•It is recommended that a water thermometer and water pressure gauge be installed in the flow and
return lines to the unit to monitor key operational parameters. !
•Note: !
•The water pipes should be subjected to a pressure test before operation of the hydronic system.!
•The water pressure of the hot water and hydronic system should not exceed 500kPa. !
•The Monoblock unit allows for water temperature up to 60 deg C. !
•Water should drain from the pressure and temperature relief valve to a drainage pipe. !
•The pressure and temperature relief valve should be periodically exercised by gently pulling the lever
up. This will help to remove possible accumulation of calcium carbonate, and ensure that the valve is
working properly. !
•Install one-way valves, filters, pressure and temperature relief valves, and any other plumbing fittings
consistently with the marked flow direction and in accord with relevant standards. !
