HOW TO USE STORAGE WATER HEATER

Note:

• Ensure the appliance is filled with water before switching on the power supply. Failure to do so will damage the heating element.
• Always turn on the Cold Water Faucet first and then adjust the Hot Water Faucet to get the desired water temperature. So as to avoid the danger of scalding when operating this appliance.
• The Safety Valve is for protection against excessive pressure in the appliance and must not be removed or replaced with non-genuine parts.
• When the heating element operates, it is normal for water to drip from the Drain Valve End. The Drain Valve End must not be closed or blocked to prevent serious damage to the appliance.
• Operate the Safety Valve at least once a month to prevent blockage at the Drain Valve End. Please refer to "Test Operation" at page EN12. Closed or blocked the Drain Valve End may cause serious damage to the appliance.
• Beware that the inlet pipe might become hot during heating process.

HOW TO USE

① Before switching on the electrical supply, turn on Hot Water Faucet at the Mixer Tap and ensure the water is in steady flow. This indicates that the Storage Tank already full with water. Then turn off the Hot Water Faucet.
② Switch on the Miniature Circuit Breaker (MCB) and the ON/OFF DP (Double Pole) Switch.

CAUTION

Press the ON/OFF DP (Double Pole) Switch before and after each usage.

③ Both ELB LED (red) and 75°C LED (orange) will light up. This indicates that the electrical supply and the heating process is going on.

④ The 75°C LED (orange) remains on until water reaches the setting temperature approximately 75°C. When the 75°C LED (orange) is turned off, it indicated that the appliance is ready to use.

Model No. T	Time required to reach a temperature of 75 °C (Approx.)
RG30AHM1	60 minutes
RG20AHM1	40 minutes

⑤ Turn on the Cold Water Faucet.
⑥ Gradually turn on the Hot Water Faucet to get the desired water temperature.

CAUTION

Always turn on the Cold Water Faucet fi rst and then adjust the Hot Water Faucet to get the desired water temperature. So as to avoid the danger of scalding when operating this appliance.

CAUTION

Note:

• After using the appliance for some time and find the water temperature is decreasing, wait for the water inside the Storage Tank to be heated up again until the 75^ LED (orange) is turned off. (This may take up some time)
• If the appliance does not operate for long time, the water inside the appliance must be drained. Refer to "MAINTENANCE" at page EN6.

MAINTENANCE

1. Enclosure cleaning

Be sure to switch off the Miniature Circuit Breaker (MCB) beforehand.

• Clean it with moist cloth.
• Never use benzene, thinner, detergent, bleach and such for cleaning purpose.
• Do not spray water to the appliance, nor put wet towels on it.
• Make sure to use suitable cloth to clean the Enclosure surface to avoid scratch.

Note:

- Do not place any material on the appliance.

2. Storage Tank cleaning

Under high temperature condition, most water deposits lime scale (white deposit). To prevent accumulation of lime scale at Storage Tank and Drain Valve End, operate the Safety Valve once a month to drain the water. Follow the instructions below:

Note:

• Safety Valve is incorporated to prevent excessive water pressure inside the appliance. In the event the pressure is exceeding 0.75 ± 0.1 MPa ( 7.5 ± 1 Bar), the Safety Valve will automatically operate and vent the water through the Drain Valve End which shall not be closed or blocked.
• When using booster pump or one-way valve at the water inlet, it is normal for water to drip from the Drain Valve End due to the excessive water pressure which will activated the Safety Valve.
• Operate the Safety Valve once a month to prevent accumulation of lime scale at the Storage Tank and Drain Valve End. Close or block the Drain Valve End may cause serious damage to the appliance.
• Storage Water Heater must use water that complies with local water quality standard to avoid contaminants and other impurities which may cause corrosion to the heater and its components thus can create hazardous condition. Failure to follow will void the warranty.

How to drain the water:

① Switch off the electrical supply.
② Turn on Hot Water Faucet of the Mixer Tap to release hot water and allow cold water to fill in the Storage Tank. Release large amount of hot water until the water temperature gradually turns cold.

WARNING

Beware of hot water release from the appliance.

③ Turn off the Main Water Valve of the main water supply.
④ Lift up the lever on the Safety Valve to start draining the water. Water must be flowing at the Drain Valve End.

WARNING	Beware that the water come out from the Drain Valve End may be hot.
CAUTION	Do not close or block the Drain Valve End of Safety Valve to prevent serious damage to the appliance.

⑤ After the water in the Storage Tank is fully discharged, push down the lever on the Safety Valve.

Note:

• Make sure to empty the Storage Tank if need to remove the appliance from its mounting.
• After maintenance, make sure the Storage Tank is completely refilled with water before switching on the electrical supply. Heating element will be damaged if electrical supply is switched on even for a short time while the appliance is dry or during filling up the Storage Tank with water. Please refer to item no.4 "Fill the Storage Tank" at page EN11.

3. Inspection on the built-in ELB

Inspect the built-in ELB (once a month) to avoid a hazard to users such as damage to property, serious injury or death.

• Make sure the appliance is in on condition.
• Press the ELB Test Button. If the ELB is in normal condition, ELB Reset Knob will slide down.
• Push up the ELB Reset Knob to reset the ELB.

4. Periodical Maintenance

Please call the service centre or similarly qualified persons once every two years to inspect the overall functions of the product.
