WATER:

1. The heater works at a minimum water flow rate of 3 litres/min. Note that for heater model without built-in pump an incoming water with consistently flow rate of 5 liters/min and above would excel its performance.
2. A typical plumbing connection is shown in diagram 2.

SAFETY:
Note: An approved type of Residual Current Device (RCD) of 10rnA sensitivity shall be installed in conjunction with the heater.

1. The built-in Earth Leakage Sensing Device (ELSD) will cut off the power supply to the heater in the event of current leakage of as low as 15mA.
2. The heater operates when there is sufficient water to trigger the Flow Switch.
3. The Thermal Cut-out would automatically cut-off the power supply if there is abnormal rise in the water temperature during shower.
4. Heater casing designed to a high degree of protection (IP25), it prevents water from entering into the heater during shower.

IMPORTANT NOTE:

1. This heater is tested suitable for use in shower cubicles. However, do not install the heater unit where is consistent spray directly over the unit.
2. If the heater’s ELSD trips during normal operation, switch off the mains supply and contact the service centre for repair(s).
3. In the event if the heater malfunctioned, never attempt to repair the unit by yourself.
4. The outlet point of this heater, hose and hand shower act as a vent. They must not be blocked, obstructed or modified in any way. Fittings not recommended by manufacturer must not be connected. The use of unapproved accessories may not only affect its performance and safety of the user but also voids its warranty.
5. If there is a sudden reduction of incoming water, the shower temperature will increase. This does not indicate the fault of the heater. Adjust the Temperature Control Knob (to reduce heating power) or Water Regulator (to increase flow) in order to get the desired shower temperature.
6. Always test the water spray temperature with your hand before stepping into the shower.
7. This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
8. Children should be supervised to ensure that they do not play with the appliance.

INSTALLATION PROCEDURES

IMPORTANT:

• All plumbing work shall be completed before proceeding to electrical wiring connection.

   • b) Connect cable to Terminal Block and fully tighten them as follows:
   • RED or BROWN . . .. .. . .. LIVE (L)
   • BLACK or BLUE ………. NEUTRAL (N)
   • GREEN/YELLOW or YELLOW/GREEN …….. EARTH
   • c) Replace the Heater Cover:
   • To ensure correct position, turn the Electronic Control Unit and Pump Control Unit (at Heater Base) to the off position (as shown in picture).
   • Install the heater cover and ensure that the Temperature Control Knob is aligned (point to ‘OFF’) to its control unit accordingly.
   • Secure the screw as shown.

6. Test Run Of Heater:

   • a) Turn on Stop Valve.
   • c) Turn on the Temperature Control Knob. The ‘HEATER’ indicator will light up. The water should be warm in a few seconds.
   • d) The water would get warmer as the Temperature Control Knob is turned clockwise.
   • e) Check the built-in ELSD as follow:
   • Press ‘TEST’ button: unit should trip and cut off power supply.
   • Press ‘RESET’ button: unit should resume normal function.
     If the above-mentioned steps prevail, the ELSD is functioning normally.

OPERATING PROCEDURES

1. Switch on the heater switch outside the bathroom. The ‘ELSD’ indicator would light up.
2. Turn on the Stop Valve. Adjust the Water Regulator for suitable water shower volume.
3. Turn on Temperature Control Knob. The ‘HEATER’ indicator would light up. The shower water would get warmer as the knob is turned clockwise from ‘ON’ to ‘MAX’.
4. Normal cold water can be selected by setting the Temperature Control Knob to ‘OFF’ position.
5. Switch off the heater switch when not in use.

Note:

• The shower water may not be hot enough even at ‘MAX’ in areas whereby the water pressure is exceptionally high and cold. This can be remedied by reducing the water inflow or replacing the unit with one that is of higher power (if it is approved by relevant authorities).
• The built-in Pump can be independently controlled by using the Pump Control Knob. In low-pressure areas (below 15 p.s.i.), adjust pump speed to obtain desired spray of water. If water pressure is high (over 15 p.s.i.), turn “OFF” the Pump Control Knob to achieve hotter shower. (Model FX-i)
• The Pump Activator is specially designed for low-pressure areas whereby the water pressure is too weak to trigger the Built-in shower Pump. Just press the Pump Activator Button and the Shower Pump will spring into action. (Model FX-i)
• It is recommended that the pump be operated at intervals of 30 minutes with 30 minutes rest in between. (Model FX-i)
