The unit CANNOT be installed near ammable gas.
Ensure that the position of the unit is level and in accordance with
AS/NZ 3500.4
This unit requires a circuit breaker and AC isolator. Failure to do so
could result in an electrical shock or re.
Do not put ngers or any other objects into the fans. Children
should be kept clear of this appliance.
In the event the iStore has a major malfunction, please shut the
power o and contact your iStore installer or iStore directly.
If the iStore needs to be relocated or installed again, only use an
authorised dealer or qualied persons.
It is prohibited for the end user to repair the unit themselves,
unless qualied. Failure to do so may lead to serious injury or, and
damage to the unit.
Should the iStore need to be repaired, only use an authorised
dealer or qualied persons.
Under no circumstances should water be sprayed directly into the

Electrical Connection:
Please check the electrical specication table. Under no circumstances shall the electrical lead be
converted to a 3 pin plug and connected to a General Power Outlet (GPO). An approved AC Isolator
shall be installed within 1m of the unit.
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.
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.
7. As water is used in the home, the cycle will restart once
the temperature in 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 15 seconds.
If the unit stops and you re start 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 eciency
(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 Teon 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
