(1) Make sure the water flow pressure.
Min. water pressure 9.8 kPa / 0.1 kgf/cm² / 1.42 psi (DH-3RL1)
4.9 kPa / 0.05 kgf/cm² / 0.71 psi (DH-3RP1)
Max. water pressure 380 kPa / 3.87 kgf/cm² / 55 psi
• How to measure the water pressure as illustrated. Water should
flow out of the Hose 2.0 m above the Main Water Valve.
Note (model DH-3RP1)
Ensure that the water feeding
into the inlet connection is
drawn from the household
gravity water storage tank and
not from the main water supply.
1. BEFORE INSTALLATION
Note: When removing the Unit from package, some water may be found inside.
This is normal as the Unit is tested during the manufacturing process.
HOW TO INSTALL ELECTRIC HOME SHOWER
Flexible Cord must enter the Unit thru designated point only (do not make additional holes).
• Proper size of the Flexible Cord and electric wiring must be installed to avoid smoke emission and fire hazards.
• Make sure to turn off electric and water supply during installation process.
• 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 the Filter Body Assembly at the outlet, inlet water cannot be filtered and allows
foreign particles to enter the Unit. It will cause the Heater Unit and the 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.
