3. For the correct size of wire conductor corresponding to different electrical

loading. Please refer to Table 1.

4. This heater operates at a minimum water flow rate of 3.0 ltr/min and

maximum water pressure of 6 bar (Multi-Point). For direct connection to the

water tank, the heater must have a minimum of 1.0m below the water tank.

5. This heater will not function if there insufficient water flow (min. 3.0ltr/min)

to trigger the flow switch.

6. In time of thunder, turn off the electric current breaker in advance to protect

the heater.

7. The built-in ELCB will automatic cut off the power supply in case there is a

current leakage as low as 15mA.

8. The thermostat will automatic cut off the power supply if it has sensed an

abnormal rise in showering water temperature.Only qualified technicians are

allowed to reset the thermal cut-out built inside the appliances.

9. (Model Multi-Point) Pressure Relief Valve is to prevents excessive built-up

of water pressure to over 0.65 MPa (6.5bars). The excess will be discharged

through the discharge nozzle, so it should not be removed from the heater. It

is recommended to service the Pressure Relief Valve at least once a year to

prevent blockage.

connection

1. Connect the Stop Valve to the Water Inlet with rubber washer. Use correct

tools to tighten and be careful not to break the plastic nut.

2. Insert Mesh Filter washer then connect the incoming water piping end to

the Stop Valve (1/2" BSP).

3. Connect the PVC Hose and Hand Shower to the outlet of the Heater, be

sure to put in the rubber washer.

4. Hook the Handshower to the Slider Rail Shower Holder and adjust to your

ideal position.

Important: The 'Water Outlet' can only be fitted to the PVC Hose and

Handshower set provided. NO CONTROL VALVE OR FITTING CAN BE

FITTED TO THE WATER OUTLET.

(For model Multi-Point)

1. Connect Pressure Relief Valve to INLET of water heater (if available). Use

sealing tape for the connection to prevent water leakage. DO NOT apply

excessive force when tightening the Pressure Relief Valve.

2. Insert Mesh Filter washer before connecting the incoming water supply to

Pressure Relief Valve.

Note :

- When connect the Pressure Relief Valve to the water inlet, please make

sure the discharge nozzle facing downward. Connect a discharge pipe (PVC

tube of dia. 8.0mm) to the discharge nozzle in a continuously downward

direction and this pipe must be left open to the atmosphere. In abnormal

condition where pressure gets higher than 6.5 bar, water will drip from this

discharge pipe.

- Connections to the Multi-point hot water system should be limited to 2 or at

the most 3 outlet usage points and they should be near to each other, e.g. in

the same bathroom but only ONE OUTLET POINTS IS TO BE USED AT ANY

ONE TIME. Extensive distance between the appliance and usage point(s) will

result not only loss but also slow response of obtaining the hot water at the

point(s) (fig.2a).

Testing

* THE WATER INLET AND OUTLET MUST BE INSTALLED CORRECTLY,

connection

OTHERWISE THE HEATER CAN NOT FUNCTION.

* DO NOT USE PLUMBING CEMENT ON CONNECTION. IF NECESSARY,

USE ONLY THREAD OR SEALING TAPE..

Turn on the water mains to drain out all plumbing dirts and to fill up the heater

tank Check for any water leakage. ( Important:This step will prevent

damage to the heating element ).
