ELECTRICAL
-
a. The installation shall comply with GP/ST/No.6/2016, Guideline for the Design, Installation, Inspection, Testing, Operation and Maintenance of the Water Heater Systems by Energy Commission.
-
b. Installation shall be done by competent person recommended by the manufacturer (MS 1957-2-35:2019).
-
c. The heater must be permanently connected to the electricity supply through a double pole linked switch having a contact separation of least 3mm in all poles incorporated in the circuit, and out of reach from the person using the shower.
d. Only fixed and permanent connection is allowed, plug and socket shall not be used. In the case where a direct connection cannot be made to the water heater, only correctly sized approved connector and connection box shall be used.
For connection within the shower cubicle and below the ceiling, the connection box shall be IPX5 rated.
An approved and correct size of PVC Cable / PVC Insulated Flexible Cables with maximum 1.5m length shall be used to connect the water heater to the connection box.
Minimum cable size must be not less than 4mm°. -
h. RCD at the main switch board of the premise need to test at least once a month.
SAFETY
Note: An approved type of Residual Current Device (RCD) of 10mA
sensitivity shall be installed in conjunction with the heater.
- a. The built-in Earth Leaking Sensing Device (ELSD) will cut off the power supply to the heater in the event of current leakage of as low as 15mA.
- b. The heater only operates when there is sufficient water flow to trigger the Flow Switch.
- c. The Thermal Cut-out will automatically cut-off the power supply if there is abnormal rise in the water temperature during shower.
INSTALLATION PROCEDURES
PLUMBING
WARNING
- a) All plumbing works shall be completed before proceeding to electrical wiring connection.
- b) Metalic / Chromed hose and conductive control valve shall not be used (in Malaysia only – Malaysian government’s regulations. Optional for others).
- c) Heater outlet shall not be connected to any form of tap or fittings not recommended b manufacturer
- a. Turn off the water source.
- b. Remove screw marked ‘A’ with a screw driver.
- c. Remove cover by lifting the bottom upward until clear.
- d. Mark out all the (4) screw points of the heater base on the wall. It is recommended that the bottom of the heater be 1.50 meters/ 5 feet above the floor of the bathroom.
- e. Drill the (4) holes with 5.0mm diameter drill bit.
- f. Mount and secure the heater with the wall plugs and screws provided.
- g. Connect the Stop Valve assembly to the INLET ‘B’. A rubber washer is provided for this connection to prevent water leakage.
- h. Connect the piping from the Stop Valve to the incoming water supply. If necessary, make use of sealing tape for the connection to prevent water leakage. Do not apply excessive force to tighten the connectors.
- i. Turn on the water mains to drain out all plumbing dirt and to fill up the heater tank.
(Note: This step will prevent damage to the heating element).
SHOWER SET FITTING (Refer to Fig. 4)
- a. Mark the positions of the two holes of the sliding rail set beside the heater – be sure that the top portion is in level with the top of the heater. Mount it with the plugs and screws provided.
- b. Connect the flexible hose and handshower to the OUTLET ‘D’ of the heater – be sure to put in the rubber washer.
- c. Connect the other end of flexible hose to handshower – be sure to put in the Filter Mesh.
ELECTRICAL CONNECTION (Refer to Fig. 5)
WARNING:
Make sure the electrical mains is off before carrying on the electrical work.
Plug, socket and undersize cable shall not be used.
- a. Switch off the electrical mains.
- b. Insert the electrical cable through the rubber grommet marked ‘E’.
- c. Connect the cable to the Terminal Block as follows:
- RED OR BROWN L…………………………………………………. LIVE (L)
- BLACK OR BLUE …..NEUTRAL (N)
- YELLOW/GREEN OR GREEN/YELLOW …………….. EARTH ( )
- d. Replace the cover and secure screw marked ‘A’ as in Fig.
TESTING
- a. Turn on the water supply at the Stop Valve. Water should spray out from the handshower.
- b. Switch on the heater switch outside the bathroom. Turn the Temperature Control Knob of the heater to the ‘ON’ position. The indicator lights would light up. The shower should be warm in a few seconds.
- c. You may proceed to ‘Operating Instructions’ before using the heater.
OPERATING INSTRUCTIONS
The heater comes with an Electronic Variable Temperature Control for a wide range of power selections. Normal cold shower can be selected by just turning the Temperature Control Knob to ‘OFF’ position.
To have a warm shower, take note of the following steps:-
- a. Switch on the heater switch located outside the bathroom. The ‘ELSD’ indicator would light up.
- b. Turn on the water supply at the Stop Valve.
- C. Turn ON the 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’. It is not necessary to return the Temperature
- Control Knob to the ‘OFF’ position when the heater is not in use.
- d. Switch off the heater switch outside the bathroom when the heater is not in use.
Note:
- The shower 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. It water pressure is high (over 15 p.s.i.), turn “OFF” the Pump Control Knob to achieve hotter shower. (Model EVO-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 EVO-i)
- It is recommended that the built-in Shower Pump be operated at intervals of 30 minutes with 30 minutes rest in between. (Model EVO-i)

gently pressing the ELSD ‘TEST’ button. The ‘ELSD* indicator light and the
‘HEATER’ light must go off. Press the ‘RESET’ button to resume power.
ADJUSTMENT OF WATER REGULATOR
Turn the knob anticlockwise to have the maximum water volume in low water
pressure areas. In high water pressure areas, turn the knob clockwise until
the desired shower temperature is attained.
CLEAN THE FILTER REGULARLY
The filter should be cleaned whenever there is a sign of inlet water blockage.
- a) Stop Valve
- Remove Filter Mesh Cap. Pull out Filter Mesh and flush it with water to remove any trapped sediments.
- Slot it back to its original position before securing it with Filter Mesh Cap.
- b) Handshower
- Handshower need to be descaled regularly.
Disconnect the handshower from the hose. Remove Filter
Mesh Washer and flush it with water to remove any trapped ver sediments.
Reconnect the handshower to the hose in its original position.
- Handshower need to be descaled regularly.
