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 efficiency
(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 off (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 Teflon 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
heater exploding. Continuous leakage of water from the valve may indicate a problem with the water heater.
