CAUTION:
THIS APPLIANCE MUST BE EARTHED
INSTALLATION
1. All plumbing work should be completed before proceeding to electrical wiring connection.
(Table 1)
2. Installation must be carried out by a qualified electrician with close reference to this manual
and in compliance with the local regulations.
3. The unit works at a minimum water flow rate of 2.0 litre/min, which then 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 a current leakage as low as 15mA.
5. The Thermal Cut-Off would automatically shut off the power supply shall there be any
abnormal rise of showering temperature.
6. The unit only operates when there is sufficient water flow to trigger the flow switch.
