How Does The iStore Work?
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 12 degrees below the target
temperature.

HOT WATER CAN CAUSE SERIOUS INJURY
WARNING – Hot water is dangerous! As a safety precaution, young children
should always be supervised around hot water fixtures
THIS WATER HEATER IS ONLY INTENDED TO BE OPERATED BY PERSONS WHO HAVE THE
EXPERIENCE OR THE KNOWLEDGE AND THE CAPABILITIES TO DO SO. THIS WATER HEATER
IS NOT INTENDED TO BE OPERATED BY PERSONS WITH REDUCED PHYSICAL, SENSORY OR
MENTAL CAPABILITIES I.E. THE INFIRM AND CHILDREN.
As solar water heaters can generate water temperature in excess of 50o C,
regulations require that an approved solar rated tempering valve shall be
installed in accordance with the valve manufacturer’s instructions. This is
required to prevent water temperatures supplied to the house exceeding a
preset safe maximum. The tempering valve is connected to the hot water outlet
lines. The valve must be fitted by an authorised plumber at the time of
installation or in retrofitting to existing systems.
CHECK THE WATER TEMPERATURE BEFORE USE, SUCH AS WHEN ENTERING A SHOWER OR
FILLING A BATH OR BASIN, TO ENSURE IT SUITABLE FOR THE APPLICATION AND WILL
NOT CAUSE SCALD INJURY.
Hot water systems can store water at temperatures that can cause scalding.
Water temperatures over 50oC can scald and care needs to be taken to ensure
that injuries do not occur through incorrect use of your water heater.
If the water heater is left unused for two weeks or more, a small quantity of
hydrogen gas (which is HIGHLY flammable) may accumulate in the top water
cylinder. To dissipate this gas safely it is recommended that a sink or bath
hot tap be turned on to dispel a couple of litres of water. During this
procedure there should be no smoking, open flames or any electrical appliances
such as washing machines or dish washers operating nearby. If Hydrogen is
discharged through the tap, it will make a sound like air escaping.
GENERAL SAFETY INSTRUCTIONS
The installation of the iStore solar hot water systems requires the expertise
of a licensed professional. The installation process must adhere to the
guidelines set forth in the National Plumbing code (AS/NZS 3500.4), Australian
Electrical Wiring Rules (AS/NZS 3000), as well as all applicable local
plumbing and electrical regulations.
The electrically operated components of this water heater operate on 240v AC
power. The removal or attempted alteration of any electrical component must be
conducted by a qualified electrical service person.
Care should be taken to avoid coming into contact with any pipe work or
fixtures associated with the water heater. For continued safety of this
appliance, it must be installed, operated and maintained in accordance with
the manufacturers instructions.
This appliance uses R290 (Propane) refrigerant, a flammable gas class 3
according to AS1677. WARNING: Risk of fire/flammable material. If the
refrigerant is leaking together with an external ignition source
WARNING there is a possibility of ignition.
Compliance with AS/NZS 5601 must be observed during storage. If a refrigerant
leak is detected, switch the unit off at the mains and contact your iStore
service agent. End of life recycling: The refrigerant must not enter the
atmosphere and can only be removed by a qualified technician.

General Operation
To prevent unwanted changes to your iStore settings. The Smart Screen will
automatically lock after 3 minutes of inactivity.
The iStore has an inbuilt controller which monitors the temperature in the
tank, when
the preset lower thermostat temperature range is reached the iStore will
commence heating and continue until the target temperature is reached.
The iStore will keep its settings and timers during a power outage but note
extended
power loss may have caused the iStore to miss its normal schedule start or
stop times, the schedule will continue as normal the following day or can be
forced ON/OFF via the LCD.
If the power to the unit is interrupted the unit will not start to run again
for approx. 3
minutes as a protection feature to safeguard the compressor.
The fan and compressor will operate continually during the heat cycle only.
The LCD will display OFF if you visit the iStore outside of its timer(s).
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 discharged
through the condensate drain line.
To manage tank pressures discharge from the Pressure and Temperature Relief
valve (PTR) and Expansion Control Valve (ECV) may occur during the heat cycle.
Heating Cycle
The Federal Government mandates a thermostat range of 12 degrees for the
iStore, this is measured in the lower region of the tank displayed in the top
left corner of the LCD.
As water is used in the home, the cycle will restart once the temperature in
the lower section of the tank has dropped 12 degrees below the target
temperature.
Note – The fan will operate only while the heat cycle is operating.

Home Owner Maintenance
Temperature and Pressure Relief valve PTV/PTR (all tanks)
The iStore Hot Water system is fitted with an 850kPa PTR Valve, which is
located on the side of the cylinder and is essential for its safe operation.
It is important that you operate the lever on the PTR valve for a few seconds
once every 6 months. It is important you release the lever gently so the valve
seat is not damaged.
Expansion Control Valve (ECV) (if applicable)
In some states and local councils, the installation of an Expansion Control
Valve (commonly referred to a coldwater expansion valve) is required to be
installed. If this valve is fitted, follow the same procedure for PTR valve as
explained above.
Condensation line
Regularly inspect the condensation line to ensure water is dripping freely for
the line. If the condensate drain is blocked at the discharge end, clear any
debris that may have collected in the line. 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.
Obstructions
Regularly check the no obstructions are interfering with the air in-take or
air discharge. If unit is installed near shrubs or trees, keep them trimmed so
they do not interfere with air flow.
Recommended iStore Servicing
2 Year Service
The recommended two-yearly service should be carried out by a licensed
tradesperson. It is recommended that this service be carried out by your local
iStore installer. The service should include the following:
1. Replace the anode (anodes should be replaced more frequently if subjected
to hard water conditions, refer table in the warranty exclusions, iStore must
be consulted regarding the replacement anode if not a genuine iStore anode).
If the TDS is greater than 600PPM, the anode shall be inspected every year and
replaced at intervals not greater than every 12 months
5 Year Service
1. Replace the anode (anodes should be replaced more frequently if subjected
to hard water conditions, refer table in the warranty exclusions, iStore must
be consulted regarding the replacement anode if not a genuine iStore anode).
If the TDS is greater than 600PPM, the anode shall be inspected every year and
replaced at intervals not greater than every 12 months
2. Replace the pressure & temperature relief valve. (PTR Valve) 3. Flush the
water heater 4. Check and clean tempering valve filters and operation

Pressure Temperature Relief Valve (PTR) / Expansion Control Valve (ECV) where applicable.
An 850kPa 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 / ECV valves are designed to allow approx. 3-5% of total tank volume to discharge during heating to cater for hot water expansion
Water pressure is slightly lower than previous hot water system
Pressure Reduction Valve (PRV)
A pressure reduction valve has been installed to limit the inlet pressure to your new iStore Water Heater. This device regulates the incoming pressure & increases life of the cylinder. This device will also protect your cylinder if the mains pressure is increased by the local water authority.
