6. The electric supply must comply with the specifications in the technical table.
7. The storage water heater must be permanetly connected to the electricity supply through a double-pole linked switch having a contact separation of at least 3mm in all poles incorporated in the circuit.
8. It is recommented to install an approved residual current device(RCD) of 10mA sensitivity and higher than heater rated current.
9. The pressure relief valve supplied with the heater must not be tampered with or replaced.
10. Slight dripping of water from pressure relief valve is normal during the heating process.
11. The overflow tube connected to the drain nozzle of pressure relief valve must be kept slopine downwards & unblocked.
12. For the first use of the heater or after maintenance or clean, ensure the heater is fully filled with water & air inside the tank has cleared befored swithing on the heater.

Remark: 1 Liter of water=1 kg
IMPORTANT
a. Thermal cut-out will break the circuit to the heating element in any event the water temperture in the storage tank becomes high(83℃±5℃).
Should this happen, switch off the heater electrical supply point and contact our nearest service centre.
b. Thermal cut-off helps to prevent the heating element from being damaged in any event the heater operates without water.

MOUNTING POSITION DIAGRAM

Ensure that the heater Hot outlet is always parallel above the Cold inlet after each installation.

INSTALLATION GUIDE

1. The heater must be installed on a solid wall and near to the point of use for convenience of water and electrical supply as well as easier for future maintenance to make sure the location is free from water flash. The selected location must support a weight two times that of the total weight of the heater fully filled with water.
Please ensure to use the mounting kits supplied with the heater. (refer to fig.1)2. According to site requirements, you may regulate the position of the flexible mounting bracket to floor, ceiling or wall mounting configuration. Once the position is confirmed, please ensure to secure the explosive bolts onto the heater and note that always tighten the supporting screws at the bottom part of the heater.
2a. Floor Type Mounting
Tighten the supporting screws at the bottom part of the heater without installing explosive bolts(refer to fig.2)2b. Wall Mounting(Left or Right)
For mounting of heater on wall, drill two holes of distance(L) on the wall depending on models and tighten the explosive bolts till 7-10mm from wall. Slowly lay the heater onto the explosive bolts both of the flexible mounting bracket holes coupled with the hooks. Pull the heater downwards to ensure that it has securely held by these explosive bolts.(refer to fig.3)

2c. Ceiling Mounting
For mounting of heater on celing, drill four holes of distance(A,B) on the ceiling and use expansive screws to fasten the heater to the ceiling.(refer to fig.4)

3. For easy maintenance of the heater, leave a space of 30cm between the front and side(control panel) and the wall.

WATER CONNECTION

IMPORTANT
Make sure the heater tank is FULLY FILLED with water before swithching on the electrical supply.

1. The diameter of inlet(BLUE) and outlet(RED) pipes is G1/2”. Before connecting external fittings to the heater, please ensure that they are resistant to the working pressure and able to withstand the maximum temperature setting of the heater.

2. Isolation Barrier
   Electric storage water heater with islation barrier can protect people from bathing in an unsafe electricity environment effectively. It is to form a permanent resistance inside the electric storage water heater, thereby reducing the electric current through the human body under abnormal conditions, eg: get electric shocks.

3. Pressure Relief Valve
   The pressure relief valve prevents excessive pressure built-up in the heater tank, and must not be removed or replaced. In the event the pressure in the tank exceeds 0.8MPa, the drain valve will operate and vent the water through the overlow tube which must not be closed or blocked. Closed or blocked the drain nozzle of the pressure relief valve may cause serious damage to the heater tank and void the warranty.

4. During the heating process, slight dripping of water from the pressure relief valve is normal. For this very reason, we recommend you to connected an overflow tube to the drain nozzle of the pressure relief valve, leaving the other end of the tube always open, and sloping it downwards pointing towards the floor trap. (refer to fig.5)

ELECTRICAL CONNECTION

This electric storage water heater is completely factory wired to 3-way connector with L(LIVE), N(NEUTRAL) and E(EARTH) marking.

1. Switch off the electrical power.

2. Remove all 4 cover screws(A,B,C,D) of the heater. (refer to fig.6)

3. Refer to fig.7 connect electrical wire as follow:
   Brown to L(LIVE)
   Blue to N(NEUTRAL)
   Green/Yellow to E(EARTH)

4. Ensure that the copper wires are properly tightened on the 3-way connector.

5. Replace the front cover.

SCHEMATIC WIRING DIAGRAM

METHODS OF USE

1. Before turning on the electrical power, ensure you have FULLY FILLED up the heater with water. To do it; open one of the hot water tap, then turn on the main water inlet in your house. Once the water flowing out from the hot water tap is normal with no choking noise, the tank is filled with water and the air inside has cleared.
2. Check for any water leaks on all the pipe fittings and the heater body.
3. Turn on the power supply to the heater, the HEATING indicator at the heater front panel will light up and the heater is in the process of heating up the water in tank to your pre-set temperature.
4. During operation, you can adjust the control knob at the front panel of the heater to make changes to the temperature. Clockwise direction is to increase the temperature and anticlockwise is to decrease the temperature.

MAINTENANCE

All repairs and maintenance work must be carried out by our technical staff or any qualified electrician.

1. Please perform a simple check on the heater before calling our Service Centre. This is to ensure that the fault is not due to lack of water or no power supply.
2. To ensure the heater operates efficently, it is recommended to clean the inner container and the deposits on the heating element once every two years.
3. Suggest to examine the aluminum anode yearly or replace it every two years. To do so, dismantle the heating element from the heater and unscrew the anode from the supporting bracket.
4. In order to drain water out, it is important to check that the water heater has been switched off long enough for the water inside to cool down before removing the pressure relief valve. Flush the valve with water to remove any deposit of salts. The valve can be removed and reattached by use of a wrench.
5. Disconnection of the water heater must be incoporated in the fixed wiring in accordance with the wiring rules.
6. Check on a regular basis that pressure relief valve is operating correctly.

TROUBLESHOOTING

Check whether the water supply is there.
Check whether the pressure relief valve over tighten. Check whether inlet water supply connected to Pressure relief valve
B.Water heater is not working| Check whether power supply is ON. Is the main lamp ON.
Is the heater lamp ON.
Is the adjustable temp.control ON. Is the mixer tap connected correctly.
C.Water not hot enough| Is the adjustable temp.control turn to maximum. Is the mixer tap adjusted correctly.
Is the water heater given enough time to heat up.(if the temp.reaches the preset temp.,the red heater lamp will go OFF automatically).
Is the water heater capacity enough for the purpose.

If any of the following abnormalities are present during usage, contact our service centres nearest to you or your sales agent immediately:
