iStore Basics

The iStore utilizes an ingenious technology to efficiently transfer thermal energy directly from the surrounding air and into water, without dependence of the sun or fossil fuels to provide an energy source.

Characteristics

Smart and efficient unit
The operational costs can be up to 75% less than that of an electric water heater, and can be installed in locations which are unsuitable for solar hot water heating.
Safe and environmentally friendly
Produces no harmful gases along with no open flame, making the unit safe to work with when installing.
Easy to operate
Featuring an easy to use timer for both start and stop operations, with a controller to set the desired water temperature.

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 pressurizes 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 liquidate 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 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 presetsafe 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.

Intelligent Operating Modes

The Federal Government Clean Energy Regulator specifies how the iStore compressor hot water systems must operate in Australia and as such how the computer control operates.
Intelligent and Hybrid modes are for overseas models and effectively overridden to Economic (ECO) mode in Australia.

Economic Heating Mode (ECO)
For Australian conditions ECO mode is the most appropriate, the onboard computer always monitors the surrounding temperature, incoming water and outgoing water, heat transfer capabilities and adjusts its operation to suit.

Vacation Mode
For use when away on holidays, enter the date of your return and the smart iStore will reduce usage to the government mandated weekly disinfect cycle only. Vacation mode reduces energy consumption while you are away.

Electric Element Heating Mode
The electric element will heat the water to the pre-set temperature and turn off once this is reached. The electric element heating mode is classified as a one-shot boost and will automatically turn off once the target temperature is reached.

Intelligent Mode – (overseas models)

Hybrid Heating Mode – (overseas models)

Did you know?

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 easing knob or lift the lever on the PTR valve once every 6 months. It is important you rotate the knob or lever gently so 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 cold-water 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 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.

Insulation
Your installation by a licensed plumber should’ve included UV stable insulation. Periodically inspect the insulation to ensure that no deterioration or damage by external influence has occurred.

Note: Up to 60% heat loss can occur if the insulation is non-existent or substandard. Therefore, please pay particular attention to making sure the system is properly insulated and any external insulation is UV Protected.

iStore hot water tank – 5 year service – Authorised/licensed plumber
The five-yearly service should be carried out by a licensed tradesperson. It is recommended that this service be carried out by your local iStore agent. The service should include the following:

1. Replace the pressure & temperature relief valve.
2. 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 2 yrs.
3. Flush the water heater.
4. Replace tempering valve if specified by valve manufacturer.

Trouble Shooting

tempering valve must be installed on every solar hot water system. Tempering valves will mix water down to 50°C.
No Power at Screen| Circuit breaker turned off AC Isolator Turned Off Power surge| Check Circuit breaker in meter box. Check AC Isolator in on position.

Contact iStore.

No Hot Water – 1| Faulty Tempering Valve| Pull PTR lever and check if water is hot. If water is hot, contact a licensed plumber to replace tempering valve.
No Hot Water – 2| Off-Peak Tariff| Check screen to see if power is available during your nominated off-peak tariff heating times. Refer to your electricity distributor should power not be available from off-peak supply.
No Hot Water – 3| Timer not set correctly| Ensure that timer is set to heat to your hot water demands. A secondary heating cycle maybe required if large hot water demand is used

twice per day. Refer above instructions for timer settings.

Luke Warm Hot Water – 1| Tempering Valve| Tempering valve not mixing water correctly. Contact a licensed plumber to inspect / replace the valve.
Luke Warm Hot Water – 2| Excessive Hot Water load| Unexpected additional hot water load. Plan hot water usage to be staggered, not continuous consumption. Wait for system to re-heat.

Increase timer setting if in use. Utilise Hybrid Mode to decrease re-heating time.

Overflow pipe is dripping| Pressure Temperature Relief Valve (PTR) / Expand- scion 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 is designed to allow 3-5% of total tank volume to discharge during heating to allow 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.
