IMPORTANT SAFETY INFORMATION
THIS APPLIANCE MUST BE EARTHED, TO MAKE SURE EARTH WIRE AND
HEATER UNIT HAVE PROPER GROUNDING IN HOUSEHOLD.
Earthing requirements
The earthing installation should be carried out in accordance with the local
wiring regulation. Where EARTHING of the premises is not evident, it is
necessary to run an EARTH CONDUCTOR and solidly connect an earth rod local
to the installation. As it's a safety factor, earthing is essential and mandatory.
It's an electrical connection between the exposed metallic parts of an electrical
appliance or installation and the earth, regarded to have zero potential. Proper
earthing provides an alternative and easy path for leakage or faulty current to
ow. It ensures that any exposed conductive part of the appliance does not
reach a dangerous level of potential or voltage that endangers the user's life. A
proper earthing system should have least electrical resistance, good corrosion
resistance and ability of dissipating high faulty current.
Consideration should be given by the young, the elderly, the inrm or anyone
inexperienced in the correct operation of the control as well as children should
be supervised to ensure that they do not play with the appliances.
When the Shower is used by someone such as child, elderly person, sick person
and physically handicapped person, the concern person is kindly requested to
pay attention and check the shower temperature by using hand from time to
time. User is advised to test and adjust the water temperature before bathing.
WARNING: Metallic / chromed hose and conductive control valve shall not be
used.
Test the build-in RCD at least once a month.
The spray head shall be descaled regularly.
WARNING: Do not switch on the heater if there is a possibility that water in the
heater is frozen.
WARNING: Whenever there’s a trip, switch OFF the incoming supply and turn ON
again than press the reset button for returning to normal operation.

2) The shower heater unit must be connected to its own independent electrical circuit.
3) Before beginning any work on the electric installation be sure that main breaker
panel switch is“O”to avoid any danger of electric shock. All mounting and
plumbing must be completed before proceeding with electrical hook-up. Lead the
power cable from the indoor fuse distributor board or Miniature Circuit Breaker
(MCB) to a 10mA RCD and from RCD to ON/OFF Double-Pole switch outside the
bathroom.
Recommended MCB rating:
Model MCB rating
F23HT 20A
R23RT 20A
4) The unit must be permanently connected to the electricity supply through a
double-pole linked. Switch having a contact of separation of at least 3mm in all
poles incorporated in xed wiring.
5) This switch must be out of reach of a person using a shower.
6) The use of a plug and socket is not recommended.
7) Correct size of wire conductor corresponding to dierent electrical loading should
be used.
Recommended power cable size:
Model Cable size
F23HT 4mm²
R23RT 4mm²
8) In order to avoid a hazard due to inadvertent resetting of the thermal cutout, this
appliances must not be supplied through an external switching device, such as a
timer, or connected to a circuit that is regularly switched on and o by the utility.
9) For ease of servicing, the unit must always be mounted on the surface of tiled walls.
Never conseal the unit and MUST be positioned vertically.
10) The unit operates at a minimum water ow rate of 2.0 litre/min and maximum
working pressure of 4 bar. For direct connection from the water storage water tank,
the unit must have an installation minimum 1.5m below the water storage tank.
11) The unit shall not be connected to any tap or tting and those not specied.
