Frequently Asked Questions - DH-3PL1 PANASONIC

Why is no hot water coming out?

Check that the Main Switch Knob is set to 'On' and the ELB Reset Lever is pushed up. Ensure the ON/OFF DP switch and Miniature Circuit Breaker (MCB) are switched on. See TEST OPERATION for ELB reset.

Why is the water not hot enough?

Adjust the water flow rate: turn the Water Volume Knob anticlockwise to reduce flow, which increases temperature. Also check the Power Control Knob is set to a higher setting. Refer to WATER FLOW RATE ADJUSTMENT.

What should I do if the ELB Reset Lever cannot be reset?

If the ELB Reset Lever cannot be pushed up or slides down immediately, stop using the unit and contact an authorized dealer. Never force it or use tape. This indicates a fault that could cause serious injury or death.

How often should I clean the shower head and filter?

Clean the shower head holes weekly using a soft brush. Clean the filter unit weekly by removing and rinsing with water. If hot water flow is poor, check and clean the filter immediately.

What is the correct installation height?

The unit must be installed vertically at 1.5 m - 1.7 m above the floor, with the water fittings pointing downward. The shower hanger should be placed so the shower head top is not higher than the unit top.

Can I use any shower hose or head with this unit?

No, only use genuine Panasonic replacement parts. Other models may not fit and could cause hazards. The unit comes with a specific shower head and hose.

Why does the water temperature fluctuate?

If the water flow rate is too low, the temperature can become very hot. Conversely, high flow reduces temperature. Also, during continuous high-temperature use, the device may temporarily reduce temperature as a safety measure.

What should I do if water leaks from the unit?

Stop using the unit, turn off the MCB, and contact an authorized dealer immediately. Leakage can indicate a serious problem. Ensure O-rings are properly seated during installation.

Is the unit suitable for use with a timer or external switch?

No, to avoid hazard due to inadvertent resetting of the thermal cut-out, the appliance must not be supplied through an external switching device like a timer or connected to a circuit that is regularly switched on and off by the utility.

What is the recommended water flow rate?

Set the main water valve so that the water splashing height (H) from the shower head is 100 cm - 110 cm, approximately 3 L/min. Adjust using the WATER FLOW RATE ADJUSTMENT procedure.

4. Turn the Main Switch Knob to "On" (ELB Lamp will light).
5. The shower temperature can be gradually controlled by turning the Power Control Knob.
   If the Power Control Knob is turned clockwise, the shower temperature will increase, reaching the highest temperature at 'High'.

- If the Water Volume Knob is turned clockwise, the volume of water will increase thus the water temperature will decrease.

- If the Water Volume Knob is turned anticlockwise, the volume of water will decrease thus the water temperature will increase. (Please refer WATER FLOW RATE ADJUSTMENT below).

1. After using this Unit, please turn off the Main Switch Knob and turn off the water supply by turning the Water Volume Knob anticlockwise until water flow is completely stop.

Note: In case of no water supply, close the Water Volume Knob by turning it anticlockwise and make sure the Main Switch Knob and the Power Control Knob are in "Off" condition (ELB light is off). This is to prevent unnecessary water flow from Shower Head after the water supply recovered.

ELB: On condition

ELB: Off condition

CAUTION

Do not block the Shower Head with hand, towel or bend the Shower Hose. The water flow rate will drop and water temperature may become very hot.

HOW TO INSTALL ELECTRIC HOME SHOWER

WARNING

• 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 is turn "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.

CAUTION

Flexible Cord must enter the Unit thru designated point only (do not make additional holes).

CAUTION

Flexible Cord must enter the Unit thru designated point only (do not make additional holes).

⑤ • Mount the Unit on the wall with 4 screws.

• Drive each Screw into the two upper Wall Plugs through the screw holes on the Back Plate.
  • After tighten up the two upper Screws, tighten up the remaining two Screws.

⑥ Please ensure the set fixed tightly on the wall by shaking it left and right.

Note: The Back Plate must be mounted with 4 Screws.

4. Electric wiring

WARNING

Proper size of Flexible Cord and electric wiring must be installed to avoid smoke emission and fire hazards.

WARNING

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.

① Lead the Flexible Cord connected to ELB terminal inside the unit: 2.5 mm², 3 core Flexible Cord.
② Unscrew the Cord Holder and fix the Flexible Cord. Strip the lead wire (coating). Fasten the life wire (L) and neutral wire (N) to the ELB (L,N) and earth wire to the Ground Point with 1 N·m (10 kgf.cm) torque. Fix back the Cord Holder to its position to clamp the Flexible Cord.

③ Connect wires in correct polarity (L,N).

• Connecting the wires in wrong polarity (L,N) causes an abnormal condition which may lead to electric leaking, burning and such.
• 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. | Main Power
• When the needle of the meter deflects greatly, the polarity of the Power-Supply Terminals is 'L'.
