1. How to adjust to maximum water flow rate.
Step 1 : Push the Push On-Off Button and select Wide Shower type on the Shower Head using the Shower Select
Lever (refer Figure 1).

It is recomended to adjust the water splashing height (H) at 35 cm ~ 45 cm (approximately 3 L/min).
(If splashing height (H) is too high, hot water temperature will drop because of an excessive flow rate).
Note: 1. Pay attention to shower temperature when reducing the volume of water.
The shower temperature will become very hot if the water flow rate is too low.
2. Water Volume Knob is at maximum position at this stage (refer Step 4).
Please adjust it to suitable flow rate using the Water Volume Knob by turning it anticlockwise.

●Do not install, remove or 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.
CAUTION
●Flexible Cord must enter the Unit thru designated point only (do not make additional holes).
BEFORE INSTALLATION
1. Make sure water flow pressure.
Min. water pressure : 9.8 kPa / 0.1 kgf/cm² / 1.42 psi
Max. water pressure : 380 kPa / 3.87 kgf/cm² / 55 psi
• How to measure the water pressure is as illustrated. Water should flow out of the Hose 2.0 m
above the Main Water Valve.
2.0 m
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.

• Connect the wires in wrong polarity (L,N) causes an abnormal condition which may lead
to electric leaking, burning, etc.
• Before wiring, please check polarity (L,N) with voltage range of a tester or voltmeter by
connecting one terminal of the meter to earth while the other to one of the Power Supply
terminals.
• When the needle of the meter deflects greatly, the polarity of the Power Supply terminal is ‘L’.

TEST OPERATION
1. • Before switch “ON” electricity supply check the wiring.
• Switch “ON” the Miniature Circuit Breaker (MCB) and ON/OFF DP (double pole) Switch.
• Set the ELB of the Unit to “On”. (Push up the ELB Reset Lever if it is down)
• Push the ELB Test Button.
• It is normal if the ELB turns “Off” (the ELB Reset Lever falls) and push the ELB Reset Lever
up. Refer figure as shown.
• Inspection on the built-in ELB (once a month) to avoid a hazard to users such as damage to
property, serious injury or death.
WARNING
If the ELB Reset Lever cannot be reset even if you push it up or if it soon slides
down during operation, please do not use the Unit and contact the authorized dealer
immediately to avoid a hazard to users such as damage to property, serious injury or
death. Never fix the ELB Reset Lever forcibly with tape, etc.
