• To mount the shower accessory, mark 2 screws points
for positioning the slider rail set beside the heater. It is
recommended the top of the portion with the top of the heater.
Remove the terminal cover from the mounting terminal and
screw the mounting to position. Close the cover.
Insert the shower holder and soap Tray.
Close the cover.
1. For the correct size of wire conductor corresponding to
different electrical loading, please refer to table 1.
2. The built – in ELSD will automatic cut off the power supply in
case there is a current leakage as low as 15mA. To ensure
correct operation of the ELSD, DO NOT installs this product if
the line voltage is lower than 175V.
3. The thermostat will automatic cut off the power if it has sensed
an abnormal rise in showing water temperature. Only qualied
technicians are allowed to reset the thermal cut- out built
inside the appliances.

Use correct tools to tighten and be careful not to break the
plastic nut.
2. Insert Mesh lter washer then connect the incoming water
piping end to the stop valve (1/2” BSP).
3. Connect the PVC hose and hand shower to the outlet of the
heater; be sure to put in the rubber washer.
4. Hook the hand shower to the slider Rail Holder and adjust to
your ideal position.
• THE WATER INLET AND OUTLET MUST BE INSTALLED
CORRECTLY, OTHERWISE THE HEATER CAN NOT
FUNCTION.
• DO NOT USE PLUMBING CEMENT ON CONNECTION. IF
NECESSARY, USE ONLY THREAD OR SEALING TAPE.

installation must be effectively connected electrically
to all exposed metal parts of other appliances in the
room in Which the heater installed.
SWITCH OFF at mains before carrying out any electrical work.
Refer to the Electrical Loading Table (Table 1) for the correct
cable size.
DO NOT install this product if the line voltage is lower than 175V.
1. Use double coated exible cable having nominal cross-
sectional area between 4 and 6 mm
2
. (IEC/EN 60335-1).
2. Lead the power cable from the circuit breaker to a “ON/OFF”
double bipolar switch outside the bathroom, then lead a cable
connected to terminal block inside the unit (g.5).
Note: Conduit entry can only from rear.
3. Connect the cable to terminal block and fully
tighten them
(insure no cable insulation is trapped under the screws) as
follow: (g.5) BROWN or RED FOR LIVE (L)
BLUE or BLACK for NEUTRAL (N)
GREEN or Green/ Yellow for EARTH ( ).
The cable clamp must be used to secure the cable. (g.6)

through the Hand shower.
2. Switch on the electrical supply and the Green Led (ELSD) lamp
will turn on (F).
3. Turn on the temperature control knob (E) to ‘ON’, the red LED
(Heater) lamp will turn on; the hot water will come out in a few
seconds. The higher the temperature indicator position, the
hotter is the shower.
4. The shower might not be enough even at the maximum position
if the incoming water supply from the mains is too cold or the
ow too high. In this case, you can adjust the water inow in
order to get the desired showering temperature.
5. Check the Built-in ELSD as follow:
• Press the “TEST” button (B), the unit should trip and cut off
the power supply,
• All leds lamps should light off.
6. Press the “RESET” button (C), the unit should resume normal
function, Green LED lamp should light on. If the above
mentioned procedures prevail, the ELSD is functioning in
normal condition.

For pump model:
8. Turn on the pump control knob (D) to test run the pump.
If the shower is not hot enough, you can adjust the knob (A)
to reduce the pump speed until you get the desired shower
temperature.
For power ON/OFF model:
9. After turn ON supply (J) and press power ON/OFF button (G)
