PERKAKAS INI MESTI DIBUMIKAN
1. All plumbing work should be completed before proceeding to electrical wiring connection. (Table 1)
2. Installation must be carried out by qualified electrician with close reference to this manual and in
compliance with the local regulations.
3. The unit works at minimum water flow rate of 2 liter/min, which would trigger the built-in pump
(only for pump model), boostering a stronger shower spray.
4. The built-in electronic Earth Leakage Circuit Breaker (ELCB) would cut-off the power supply to heater
in the event of current leakage of as low as 15mA.
5. The Thermal Cut-Off would automatically shut off the power supply shall there is any abnormal rise
of showering temperature.
6. The unit only operates when there is sufficient water flow to trigger the flow switch.

1. All the plumbing works should be completed before proceeding
to electrical wiring connection.
2. INLET and OUTLET connection of the heater unit should not be
reversed, with stop valve installed on INLET. (Diagram 1)
3. It is recommended to mount the unit at 1.5mm above the
floor to bottom of the hater.
4. Mounting position (Refer Diagram 2)
• Remove screw from the bottom of the heater
• Lift the plastic cover upward
• Mark mounting position on the wall for all
4 screws
• Drill the holes with 5.0mm diameter drill bit
(Refer Diagram 3)
• Install the unit to the wall with plug
5 Installation of Heater INLET and OUTLET connection.
a) Connect the stop valve to INLET, and be sure to put a
gasket to prevent water leakage.
b) Connect the pipe from the stop valve to incoming
water supply. If necessary make use of sealing tape
for the connection to prevent water leakage.
