iStore Basics

The iStore utilizes advanced technology to efficiently transfer thermal energy from the surrounding air directly into water, independent of the sun or fossil fuels.

Characteristics

• Smart and Efficient: Operational costs can be up to 75% less than electric water heaters. Suitable for locations not ideal for solar hot water heating.
• Safe and Environmentally Friendly: Produces no harmful gases and has no open flame, making it safe for installation and use.
• Easy to Operate: Features an intuitive timer for start and stop operations.

How Does The iStore Work?

The iStore operates on a heat pump principle:

1. A fan draws in air containing heat energy across the evaporator.
2. The evaporator converts the liquid refrigerant into a gas.
3. The compressor pressurizes the refrigerant, turning it into a hot gas.
4. This hot gas heats the water inside the coil-wrapped tank via the condenser coil.
5. The refrigerant reverts to a liquid after heating the water and returns to the evaporator to repeat the process.
6. The cycle continues until the set target temperature is achieved.

As water is used, the cycle restarts when the temperature in the lower section of the tank drops 5 degrees Celsius below the target temperature.

Diagram Description: A visual representation of the iStore heat pump cycle shows air being drawn in (1), passing over an evaporator (2), compressed (3), heating water in a tank via a condenser (4), with refrigerant returning to liquid (5) and repeating the cycle (6) until the target temperature is met.

Safety Precautions

⚠️ HOT WATER CAN CAUSE SERIOUS INJURY!

Hot Water Warning:

• Hot water is dangerous. Young children should always be supervised around hot water fixtures.
• This water heater is intended for operation by persons with experience, knowledge, and capabilities. It is not intended for persons with reduced physical, sensory, or mental capabilities, including the infirm and children.
• As solar water heaters can generate temperatures exceeding 50°C, regulations require an approved solar-rated tempering valve to prevent scalding. This valve must be installed by an authorized plumber.
• Always check water temperature before use (e.g., showering, bathing) to ensure it is suitable and will not cause scalding.
• Water temperatures over 50°C can scald. Exercise care to prevent injuries.
• If the unit is left unused for two weeks or more, flammable hydrogen gas may accumulate. To dissipate safely, turn on a hot tap for a few liters of water. Ensure no smoking, open flames, or operating electrical appliances are nearby during this procedure. Hydrogen discharge may sound like escaping air.

General Safety Instructions

• Installation requires a licensed professional and must comply with AS/NZS 3500.4, AS/NZS 3000, and all applicable local regulations.
• Electrically operated components run on 240v AC. Removal or alteration of electrical components must be done by a qualified service person.
• Avoid contact with pipework or fixtures associated with the water heater.
• For continued safety, install, operate, and maintain according to manufacturer instructions.
• This appliance uses R290 (Propane) refrigerant, a Class 3 flammable gas.

⚠️ WARNING: Risk of fire/flammable material. Refrigerant leaks with an external ignition source can cause ignition.

Compliance with AS/NZS 5601 is required. If a refrigerant leak is detected, switch off the unit at the mains and contact your iStore service agent. Refrigerant must be removed by a qualified technician at end-of-life.

General Operation

• The Smart Screen automatically locks after 3 minutes of inactivity to prevent unwanted changes.
• The iStore controller monitors tank temperature. Heating commences when the lower thermostat range is reached and continues until the target temperature is met.
• Settings and timers are retained during power outages. Extended outages may cause missed schedules; the schedule resumes the next day or can be manually forced ON/OFF via the LCD.
• If power is interrupted, the unit will delay starting for approximately 3 minutes to protect the compressor.
• The fan and compressor operate only during the heat cycle.
• The LCD displays "OFF" if visited outside of programmed timer(s).
• Condensation occurs during the heat cycle as humidity is drawn from the air and discharged via the condensate drain line.
• Pressure and Temperature Relief (PTR) valve and Expansion Control Valve (ECV) may discharge during the heat cycle to manage tank pressures.

Heating Cycle

The Federal Government mandates a 5°C thermostat range for the iStore, measured in the lower tank region (displayed on the LCD). The cycle restarts when the lower tank temperature drops 5°C below the target. The fan operates only during the heat cycle.

Home Owner Maintenance

• Temperature and Pressure Relief (PTR) Valve: The iStore is fitted with an 850kPa PTR Valve. Operate the lever for a few seconds every 6 months, releasing it gently to avoid damaging the valve seat.
• Expansion Control Valve (ECV) (if applicable): If fitted, follow the same procedure as the PTR valve.
• Condensation Line: Regularly inspect the line to ensure water drips freely. Clear any blockages at the discharge end. Condensation is normal during operation and is discharged via the drain line. Up to 5 litres per day may be expected in high humidity (>80%).
• Obstructions: Ensure air intake and discharge are clear. Trim nearby shrubs or trees if they obstruct airflow.

Recommended iStore Servicing

• 2 Year Service: Recommended to be carried out by a licensed tradesperson, preferably your iStore installer. Includes:
• Replace the anode (more frequently if hard water; consult iStore if not genuine). If TDS > 600PPM, inspect anode annually and replace every 12 months.
• Replace the Pressure & Temperature Relief valve (PTR Valve).
• Flush the water heater.
• Check and clean tempering valve filters and operation.
• 5 Year Service: Includes all 2-year service items plus:
• Replace the anode (as per 2-year service conditions).
• Replace the Pressure & Temperature Relief valve (PTR Valve).
• Flush the water heater.
• Check and clean tempering valve filters and operation.
