ELECTRICAL:
IMPORTANT: THIS APPLIANCE MUST BE EARTHED.
1. All wiring MUST conform to local regulations. If in doubt, always consult a qualified
electrician.
2. Installation must be carried out by a qualified electrician.
3. The heater must be permanently connected to the electricity supply through a double
pole linked switch having a contact separation of at least 3mm in all poles incorpo-
rated in the circuit, and out of reach from the person using the shower.
4. The use of plug and socket is not recommended.
5.
Correct size of wire conductor corresponding to different electrical loading should be
used. Table below provides a reference for selecting the correct type of wire conductor.
6. A typical electrical wiring connection is shown in diagram 1.

GENERAL INFORMATION
GENERAL INFORMATION
WATER:
1. The heater works at a minimum water flow rate of 3 liters/min. Note that an
incoming water flow rate of 5 liters/min and above would excel its performance.
2. A typical plumbing connection is shown in diagram 2.
SAFETY:
1. The built-in Earth Leakage Sensing Device (ELSD) would cut off the power supply
to the heater in the event of current leakage of as low as 15mA.
2. The built-in Line Fault Detector will indicate ‘Green’ light if wiring is done correctly
or ‘Red’ light if improper electrical wiring is detected.
3. The heater operates when there is sufficient water to trigger the Flow Switch
.
4. The Thermal cut-out would automatically breaks off the power supply if there is
abnormal rise in shower temperature.
5. Heater casing designed to high degree of protection IP25 prevents water from enter-
ing 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 sales agent for repair(s).
3. If the Line Fault Indicator indicate RED light, switch off the mains supply and
contact a qualified electrician to check the electrical supply line (refer Page 9
for possible cause(s)).
4. In the event the heater malfunctions, never attempt to repair the unit yourself.
5.
The outlet point of this heater, hose and handshower act as a vent. They must not be
blocked, obstructed or modified in any way. Fittings not recommended by manufac-
turer must not be connected. The use of unapproved accessories may not only affect
its performance and safety of the user but also invalidate its guarantee.
6.
If there is a sudden reduction of incoming water, the shower temperature will increa-
se. This does not indicate the fault of the heater. Adjust the Temperature Control
Knob (to reduce heating power) or Regulator Unit (to increase flow) in order to get
the desired shower temperature.
7. Always test the water spray temperature with your hand before stepping into the
shower.
8. 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.
Important: An approved type of Residual Current Device (RCD) of 10mA sensitivity
should be installed in conjunction with the heater.
* Line Fault Indicator is optional device in accordance with each country’s requirement.

INSTALLATION PROCEDURES
INSTALLATION PROCEDURES
1 Decide the mounting position:
a) Turn off the water source.
b) Remove screw at the bottom of the
heater.
c) Remove Heater Cover by lifting the
bottom upward.
d) Mark out 4 mounting points on the
wall.
Note: It is recommedded that mount the
bottom of the heater be 1.50 meters
/ 5 feet above the floor of the bath-
room. However the height of the in-
stallation level is at the discretion of
the user.
2 Mounting of the heater:
a) Drill the 4 holes with 5.0mm dia-
meter drill bit.
b) Put in the wall plugs and install the
heater to the wall with screws pro-
vided.
3 Shower Accessories Installation:
a) Fix the Rotatable Soap Dish, Sho-
wer Holder and Rail Supports (Top
and Bottom) on to the Sliding Rail.
b) Mark the positions of the 2 holes of
the Rail Supports - be sure that the
top portion is in level or not higher
than the top of the heater.
c) Drill the holes and mount the Sho-
wer Accessories with wall plugs and
screws provided. Insert the Rail Sup-
port Caps on to the Rail Supports.

IMPORTANT:
• All plumbing work should be completed before proceeding to electrical wiring
connection.
• Metalic / Chromed hose and conductive control valve shall not be used (in Malaysia
only- Malaysian government’s regulations. Optional for others).
• Heater outlet shall not be connected to any tap or fittings not recommended by
manufacturer.
• The heater unit must be installed on solid wall to avoid the possibility of distorting the
unit.
• Inlet and Outlet connections of the heater should not be reversed.

4 Connection of heater Inlet and Outlet:
a) Connect Stop Valve to heater Inlet
with use of the rubber seal provi-
ded.
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 handshower 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 handshower - be sure to
put in the Filter Mesh Washer in
order to prevent dirt from entering
the handshower.
Do not apply excessive force to
tighten any of the connections.
Excessive force may cause dama-
ge to the connector.
Do not bend the Flexible Hose or
install any accessories which can
block the water flow at heater out-
let.

5 Electrical Connection:
Important: Make sure the electrical mains is off
before carrying on the electrical work.
a) Insert electrical cable through the rub ber
gromment for side entry or rear cable
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 to the off position
(as shown in picture).
ii) Install the heater cover and ensure
that the
Temperature Control Knob
is aligned (point
to ‘OFF’) to its control unit
accordingly.
iii) Secure the screw as shown.
6 Test run of heater:
a) Turn on water supply at the Stop Valve.
Turn on all the faucets connected to the
hot water piping system until a consistant
flow of water is obtained from all the
faucet outlet (For Close Outlet heater only).
(This step will ensure that the heater tank
is filled with water and this will prevent
damage to the heating element).
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 water should be warm in a few seconds. The built-in flow switch will
cut off the heater power if all the faucet points had turned off.
c) Test the ELSD by pressing the ‘TEST’ button. The ‘ELSD’ and ‘HEATER’ indicator
lights should go off. Press the ‘RESET’ button to switch on the heater again.
If the above mentioned steps prevail, the ELSD is functioning normally.

would light up.
b. Turn on the water supply at the top valve.
c. Turn ‘ON’ the Temperature Control Knob. The ‘HEATER’ indicator would light up.
The shower would get warmer as the control knob is turned clockwise from ‘ON’ to
‘MAX’. It is not necessary to turn back the 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 water may not be not enough even at ‘MAX’ in areas where 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.
