Installation of wired remote controller
For convenience of operation, please install the wired remote controller in an easily accessible
location on the wall near the water heater. The length of the wire for wired remote controller is
approximately 8 feet. Please ensure that the wired remote controller is neither immersed in
water nor installed in a place where it gets into direct water contact.
1. Drill two holes on the wall by using an electric impact drill with 5mm bit.
2. The holes must be aligned vertically (Fig. 7). Space between two holes should be 24mm (Fig. 8).
3. Fix the bracket on the wall by expansion tubes and screws attached.

Caution:
• Once the mounting, plumbing, discharge tube, power connection and water filling
is completed, then only the power supply should be given.
• During repair or periodic maintenance, if necessary, the power cord or Internal
electrical wiring should be replaced by authorised service personnel only.
• It is not permitted for the power supply plug and cord to be replaced or altered by
unauthorised people or by the users themselves. This will make the warranty null and
void and may cause the water heater operation hazardous.
