PANASONIC WH-ADC0309K6E5 (01) PDF Document

Before installing your PANASONIC WH-ADC0309K6E5, carefully read the “SAFETY PRECAUTIONS”. Electrical and water installation work must be performed by licensed professionals. These precautions are crucial for safety.

WARNINGS (Possibility of causing death or serious injury):

• Do not use unapproved methods to accelerate defrosting or to clean the unit.

• Do not install the outdoor unit near a veranda handrail where a child might climb it.

• Use dedicated power cords; do not use unspecified, modified, joint, or extension cords. Do not share the outlet.

• Do not insert fingers or objects into the unit; the high-speed rotating fan can cause injury.

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

• Keep plastic packaging away from children to prevent suffocation.

• When installing or relocating, do not allow substances like air to mix into the refrigerant cycle.

• Do not pierce or burn the appliance as it is pressurized. Keep it away from heat, flames, and sparks.

• Do not add or replace refrigerant other than the specified R32 type.

• Do not use joint cables for connections between the Tank Unit and Outdoor Unit. Use specified cables and connect them tightly.

• Arrange wiring so that the control board cover can be fixed properly to prevent fire or electrical shock.

• This equipment must be properly earthed. Do not connect the earth line to gas pipes, water pipes, or telephone lines.

CAUTIONS (Possibility of causing injury or property damage):

• Do not install the unit where flammable gas may leak.

• Do not release refrigerant during piping work; it can cause frostbite.

• Do not install in a laundry room or other high humidity locations to prevent rust and damage.

• Do not touch the sharp aluminum fins.

• Carry out drainage piping correctly to prevent water from entering the room and damaging furniture.

The basic installation procedures for the PANASONIC WH-ADC0309K6E5 are similar to conventional refrigerant models (R410A, R22), but you must pay careful attention to the following points due to the properties of R32 refrigerant.

Equipment and Tools:

• The working pressure of R32 is higher than R22, so some piping, installation, and service tools are special. When replacing an R22 model, you must replace the conventional piping and flare nuts with those specified for R32/R410A.

• Models using R32 have a different charging port thread diameter (12.7 mm or 1/2 inch) to prevent accidental charging with other refrigerants.

Handling and Installation:

• Ensure foreign matter (oil, water, etc.) does not enter the piping. Securely seal piping openings when storing them.

• Operation, maintenance, and refrigerant recovery must be carried out by trained and certified personnel.

• Do not locate any part of the refrigerating circuit or piping near heat sources, open flames, or operating gas/electric appliances.

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

• Piping in occupied spaces should be installed to protect against accidental damage.

• Avoid excessive vibration or pulsation to refrigerating piping.

• Field-made refrigerant joints indoors must be tightness tested. The test method must have a sensitivity of 5 grams per year of refrigerant or better under a pressure of at least 0.25 times the maximum allowable pressure.

Servicing:

• Any qualified person working on a refrigerant circuit must hold a current valid certificate from an industry-accredited assessment authority.

• Servicing should only be performed as recommended by the manufacturer.

• Before working on systems with flammable refrigerants, safety checks are necessary to minimize the risk of ignition. This includes working under a controlled procedure, avoiding confined spaces, wearing appropriate protective equipment, and keeping all ignition sources away.

• The work area must be checked with an appropriate refrigerant detector before and during work.

• Ensure leak detection equipment is suitable for flammable refrigerants (non-sparking, adequately sealed, or intrinsically safe).

• Keep a dry powder or CO2 fire extinguisher adjacent to the charging area.

• Ensure the area is well-ventilated before and during any work on the system.
