PANASONIC WH-UDZ09KE5 (01) PDF Document

Read the “SAFETY PRECAUTIONS” carefully before installation. Electrical and water installation works must be done by a licensed electrician and a licensed water system installer, respectively. Use the correct rating and main circuit for the model. The caution items must be followed as they are related to safety. Incorrect installation can cause harm or damage.

WARNINGS:

1. Do not use un-recommended means to accelerate the defrosting process or to clean. Unfit methods or incompatible materials may cause product damage, burst, and serious injury.

2. Do not install the outdoor unit near a handrail of a veranda to prevent accidents.

3. Do not use unspecified, modified, joint, or extension cords for the power supply. Do not share the outlet with other appliances.

4. Do not tie the power supply cord into a bundle. An abnormal temperature rise may occur.

5. Do not insert fingers or other objects into the unit; the high-speed rotating fan may cause injury.

6. Do not sit or step on the unit, as you may fall.

7. Keep plastic packaging material away from children to prevent suffocation.

8. When installing or relocating the outdoor unit, do not let any substance other than the specified refrigerant (e.g., air) mix into the refrigerant cycle.

9. Do not use a pipe wrench to install refrigerant piping; it might deform the piping.

10. Do not purchase unauthorized electrical parts for installation or service.

11. Do not modify the wiring of the outdoor unit for other components (e.g., heater).

12. Do not pierce or burn the appliance as it is pressurized. Do not expose it to heat, flame, sparks, or other ignition sources.

13. Do not add or replace refrigerant other than the specified type.

14. Do not place containers with liquids on top of the Tank Unit.

15. Use specified connection cables for the Tank Unit / Outdoor Unit and connect them tightly. Clamp the cable so no external force acts on the terminal.

16. Do not use a joint cable for the outdoor connection cable. Use the specified cable and connect it tightly.

17. Wire routing must be properly arranged so that the control board cover is fixed properly.

18. For electrical work, follow national regulations and use an independent circuit and single outlet.

19. Follow local wiring standards and regulations for electrical work.

20. For water circuit installation, follow relevant European and national regulations (including EN61770) and local codes.

21. Engage an authorized dealer or specialist for installation.

22. This is an R32 model. Use piping, flare nuts, and tools specified for R32 refrigerant. Copper pipes must be thicker than 0.8 mm.

23. Install the refrigerant piping properly before running the compressor.

24. During pump down, stop the compressor before removing refrigeration piping.

25. Tighten the flare nut with a torque wrench to the specified method.

26. After installation, confirm there is no leakage of refrigerant gas.

27. Ventilate if there is refrigerant gas leakage during operation.

28. Use attached accessories and specified parts for installation.

29. This equipment must be properly earthed. Do not connect the earth line to a gas pipe, water pipe, lightning rod, or telephone line.

CAUTIONS:

1. Do not install the Tank Unit where flammable gas leakage may occur.

2. Do not release refrigerant during piping work, re-installation, or repair. Liquid refrigerant may cause frostbite.

3. Do not install this appliance in a laundry room or other high humidity locations.

4. Ensure the insulation of the power supply cord does not contact hot parts.

5. Do not touch the sharp aluminum fin; sharp parts may cause injury.

6. Do not apply excessive force to water pipes.

7. Carry out drainage piping as mentioned in installation instructions.

8. Select an installation location that is easy for maintenance.

The basic installation procedures are the same as for conventional refrigerants (R410A, R22), but pay careful attention to the following points:

WARNINGS:

1. The working pressure is higher than R22 models, so some piping, installation, and service tools are special. When replacing an R22 model with a new R32 model, always replace the conventional piping and flare nuts.

2. Mixing different refrigerants is prohibited. R32 and R410A models have a different charging port thread diameter to prevent erroneous charging.

3. Ensure foreign matter (oil, water, etc.) does not enter the piping. Securely seal the opening when storing piping.

4. Operation, maintenance, repair, and refrigerant recovery should be carried out by trained and certified personnel.

5. Any part of the refrigerating circuit or piping should not be located near heat sources, open flames, or operating gas/electric appliances.

6. Regularly check alarms, mechanical ventilation, and detectors at least once a year as required by national regulations.

7. A logbook of checks must be maintained.

8. For ventilations in occupied spaces, check to confirm no obstruction.

9. Before a new system is put into service, ensure operating personnel are instructed on its construction, supervision, operation, and maintenance.

10. Trained and certified personnel must have knowledge of legislation, regulations, standards, and skills in handling flammable refrigerants, PPE, leakage prevention, charging, leak detection, recovery, and disposal.

11. Piping in the occupied space must be installed to protect against accidental damage.

12. Precautions must be taken to avoid excessive vibration or pulsation to refrigerating piping.

13. Ensure protection devices and fittings are well-protected against adverse environmental effects.

14. Expansion and contraction of long piping runs must be designed and installed securely.

15. Protect the refrigerating system from accidental rupture due to moving furniture or reconstruction activities.

16. To ensure no leaking, field-made refrigerant joints indoors shall be tightness tested. The test method must have a sensitivity of 5 grams per year of refrigerant or better. No leak shall be detected.

b) Electric cable connecting work is properly done.

c) The Tank Unit is filled with water and trapped air is released.

d) Power is supplied to the tank and it is full.

2. Switch ON the power supply to the Tank Unit. Set the Tank Unit RCCB/ELCB to the “ON” condition. Then, refer to the Operation Instruction for the operation of the Remote Controller.

Note: During winter, turn on the power supply and standby the unit for at least 15 minutes before the test run to allow sufficient time for the refrigerant to warm up and prevent wrong error code judgment.

3. For normal operation, the Water Pressure reading should be between 0.05 MPa and 0.3 MPa (0.5 bar and 3 bar). If necessary, adjust the Water Pump SPEED to obtain the normal water pressure operating range. If adjusting the pump speed does not solve the problem, contact your local authorized dealer.

4. After the test run, clean the Magnetic Water Filter Set and Water Filter Set, then reinstall them.

To open and close the Front Plate:

1. Remove the 2 mounting screws from the Bottom Front Plate.

2. Slide it upwards to unhook the Bottom Front Plate hook.

When an abnormality occurs during operation, the PANASONIC WH-UDZ09KE5 system will stop, and the OFF/ON control panel LED will blink, displaying a three-digit alphanumeric error code on the control panel.

• Even if the error code is reset by turning the power OFF or selecting ERROR RESET, the system will stop again and display the error code if the abnormality is not repaired.

• The error code is stored in the IC memory.

To check the error code, observe the display on the control panel when the system stops and the LED blinks. Refer to the error code table to understand the description of the abnormality. You can also view past error codes through the “Error history” menu in “System check”.
