General Plumbing Connection

WATER:

1. Heater with built-in Shower Pump works at minimum flow rate of 1.5 liters/min. Heater without built-in Shower Pump works at minimum flow rate of 2 liters/min. Note that heater model without built-in Shower 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 10mA 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. Upon power on at mains, the heater will perform 10 seconds ‘self-test’ routine. If the ELSD is in proper working condition after the ‘self-test’, the AUTO TEST indicators will light up GREEN and heater will be in power. If ELSD is faulty, its AUTO TEST indicators will blink RED and power will be cut off from heater.
3. The built-in Line Fault Detector will indicate ‘GREEN’ light if wiring is done correctly or ‘RED’ light if improper electrical wiring is detected.
4. The heater operates when there is sufficient water to trigger the Flow Switch.
5. The Thermal Cut-out will automatically cut-off the power supply if there is abnormal rise in the water temperature during shower.
6. 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 the 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 center for repair(s).
3. If the Auto Test and Line Fault Indicator indicate RED light, switch off the mains supply and contact a qualified electrician to check the electrical supply line (refer Page 11 for possible cause(s)).
4. In the event if the heater malfunctioned, never attempt to repair the unit by yourself.
5. The water inlet of this appliance shall not be connected to inlet water obtained from any other water heating system.
6. 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.
7. 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.
8. Always test the water spray temperature with your hand before stepping into the shower. 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.
9. Children should be supervised to ensure that they do not play with the appliance.
10. The new hose-sets supplied with the appliance are to be used and that old hose-sets should not be reused.
11. The new hose-sets supplied with the appliance are to be used and that old hose-sets should not be reused.

4. Connection of heater Inlet and Outlet:** a)Connect Stop Valve to heater Inlet with use of the rubber seal provided. b) Connect incoming water supply to Stop Valve. If necessary make use of the sealing tape to prevent water leaking.
   c)** Connect Flexible Hose to heater Outlet. (Do not connect the other end of flexible hose to hand shower at this stage).

d) Turn on the water supply to drain out all the plumbing dirt and to fill up the heater tank. (This step will prevent damage to Heating Element.)

e) Connect the other end of flexible hose to hand shower – be sure to put in the Filter Mesh Washer in order to prevent dirt from entering the hand shower.
Note:

  * Do not apply excessive force to tighten any of the connections.
  * Excessive force may cause damage to the connector.
  * Do not bend the Flexible Hose or install any accessories which can block the water flow at heater outlet.

5. Electrical Connection:
   CAUTION:
   

   • Make sure the electrical mains is off before carrying on the electrical work.
     

   • Plug, socket and undersize cable shall not be used.
     a) Insert electrical cable through the rubber grommet for Side Entry or Wall Embedded Entry.
     
     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:

i) To ensure correct position, turn the Electronic Control Unit and Pump Control Unit (at Heater Base) to the off position (as shown in picture).
ii) Install the heater cover and ensure that the Temperature Control Knob and Pump Control Knob are aligned (point to ‘OFF’) to their control unit accordingly.
iii) Secure the screw as shown.

6. Test Run Of Heater:
   

a) Turn on Stop Valve.

b) Switch on heater switch. The ‘AUTO TEST’ and ‘LINE FAULT INDICATOR’ will light up.

Proceed to step (c) if ‘AUTO TEST’ and ‘LINE FAULT INDICATOR’ displays green light.

CAUTION:
Stop using the heater and check the wiring if ‘AUTO TEST’ and ‘LINE ° FAULT INDICATOR’ displays RED light (refer page 11 for possible causes).

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:

1. Press ‘TEST’ button: unit should trip and cut off power supply.
2. 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 ‘AUTO TEST’ and ‘LINE FAULT’ indicator would light up.
   CAUTION:
   ‘AUTO TEST’ and ‘LINE FAULT INDICATOR’ must indicate green.
   Otherwise the unit must not in use and contact agent for repair.

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 would get warmer as the Temperature Control Knob is turned clockwise from ‘ON’ to ‘MAX’.

4. Normal cold shower 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 shower 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 Smart 18EP/18i)

   • 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 built-in shower Pump will spring into action. (Model Smart 18EP/18i)

   • It is recommended that the built-in shower Pump be operated at intervals of 30 minutes with 30 minutes rest in between. (Model Smart 18EP/18i)

CUSTOMER GUIDANCE
