Electrical Connection:
The installation of the iStore must strictly follow the AS/NZS 3000 wiring rules and local wiring
regulations, ensuring that a licensed electrician deems the circuit suitable. Adequate overload
protection and a residual current device of appropriate size should be installed. Opeak and
controlled load circuits are acceptable as long as there is a manual override option for maintenance
and support during business hours.
500kPa Pressure Reduction Valve:
Pressure Reduction Valve (PRV 500) - A pressure reduction valve of 500kPa maximum must be tted
immediately downstream of the cold water non-return isolation valve. Failure to install a pressure
reduction valve will void the warranty. Please note cold water supply line to the tempering valve must
be run after the PRV to ensure equal supply pressure to the tempering valve. This valve is not required
shall a 500kPa PRV be installed at the water main supply to the property.
Note: In SA, WA & QLD (and some other areas of other states subject to local authority regulations) it is a requirement that
an expansion control valve be tted between the non-return isolating valve and the water heater.
iStore Basics
How it works
1. A fan draws in air, containing heat energy,
across the evaporator.
2. The evaporator turns the liquid refrigerant
into a gas.
3. The compressor pressurises the refrigerant
into a hot gas.
4. The hot gas inside the condenser coil heats
the water inside the coil-wrapped tank.
5. The refrigerant reverts back to a liquid after
heating the water and continues to the
evaporator for the process to start again.
6. The cycle continues until the set target
temperature is achieved.
As water is used in the home, the cycle will
restart once the temperature in the
lower section of the tank has dropped
11 degrees below the target temperature.

Hot and Cold Water Connections
All plumbing connections must be performed by a licensed plumber in accordance with local authority regulations.
The cold water inlet connection to the storage tank is 3/4 FI. All pipes and valves must be insulated as per the current AS/NZ 3500.4 Section
8.2. The cold water inlet requires the following valve train please refer to system diagram page for correct installation.
• Approved isolating/non return valve
• 500 kPa Pressure Reduction Valve (PRV) valve
• 700 kPa Expansion Control Valve (ECV)
The maximum inlet water pressure rating is 750kPa. Cold water supply pressures exceeding 500kPa a 500kPa Pressure Reduction valve
shall be installed immediately downstream from the Duo valve.
The hot water outlet from the tank is ¾ inch FI. All hot water pipes must be insulated by UV stable & appropriately rated insulation.

Safety Features
To prevent unwanted changes to your iStore settings. The Smart Screen will automatically lock after 3 minutes.
If the unit stops and you restart the unit or turn it on by the manual switch, the unit will not start to run again for
approx. 3 minutes. This is a protection feature to safeguard the compressor.
In the heating mode the unit will defrost automatically, maximizing the heating eciency
(Lasting 2 - 10 minutes). The fan motor will stop running whilst the unit is defrosting.
In order to use the unit correctly, please operate the unit at ambient temperature of -7º ~ 50º Celsius.
If the water temperature reaches 85º C, the power of unit will be cut o (refer to manual to reset).
An 850kPa, 10kW and 99°C PTR valve is used on the iStore water tank, which is located on the side of the
water tank and is essential for its safe operation. The PTR valve is designed to allow 3-5% of total tank volume
to discharge during heating to allow for hot water expansion. Water may drip from the discharge pipe of the
pressure-relief valve. The discharge pipe must be left open to the atmosphere under all circumstances. PTR
Valve the discharge pipe shall be installed downwards and with discharge pipes in a frost free environment.
Refer page 12 for how to connect. Seal the thread with approved sealant such as Teon tape and screw the
valve into the correct opening and leave the valve outlet pointing downwards. The discharge pipe diameter is
permitted to be run in 15mm copper providing the length of discharge pipe does not exceed 9m.
During normal operation, condensation occurs from the transfer of air across across the evaporator coil. This
process is drawing humidity from the air and creates condensation/water droplets on the coils, which in turn is
captured in the fully moulded condensate tray and discharged through the condensate drain line. In locations
with humidity greater than 80%, up-to 5 litres per day can be expected under normal operating conditions.

DANGER: Failure to operate the relief valve easing gear at least once every six months may result in the water
