HOW TO INSTALL ELECTRIC HOME SHOWER

• Proper size of Flexible Cord and electric wiring must be installed to avoid smoke emission and fire hazards.
• During installation process make sure electric and water supply are turned "OFF".
• The home shower must be permanently connected to the electric supply through the ON/OFF DP (double
pole) Switch having a contact separation of at least 3 mm in all poles incorporated in the fixed wiring. This
switch must be clearly identifiable but out of reach of a person using a fixed bath or shower.
The Unit must be earthed.
Improper grounding could cause electric shock.
• Never install Filter Body Assembly at the outlet, inlet water cannot be filtered and allows
foreign particles to enter the Unit. It will cause Heater Unit and Shower Head to clog up.
• Do not install, remove and reinstall the Unit by yourself.
Improper installation will cause leakage, electric shock or fire. Installation and wiring must be
done by competent personnel.
• Do not share the inlet and outlet pipe of the Home Shower Unit with other outlets.
The pressure may drop due to water being drawn off at other point. The shower temperature
may become very hot.
• Flexible Cord must enter the Unit thru designated point only (do not make additional holes).
