WARNING
General
• Models that use refrigerant R32 and R410A have a different
charging port thread diameter to prevent erroneous charging with
refrigerant R22 and for safety
• Do not use means to accelerate the defrosting process or to
clean, other than those recommended by the manufacturer.
• The appliance shall be stored in a room without continuously
operating ignition sources.
(For example: open flames, an operating gas appliance or an
operating electric heater.)
• Do not pierce or burn.

charged with refrigerant at the manufacturing location or charged
on site as recommended by the manufacturer.
A part of an appliance that is charged on site, which requires
brazing or welding in the installation shall not be shipped with a
flammable refrigerant charge. Joints made in the installation
between parts of the refrigerating system, with at least one part
charged, shall be made in accordance with the following.
- A brazed, welded, or mechanical connection shall be made
before opening the valves to permit refrigerant to flow between
the refrigerating system parts. A vacuum valve shall be provided
to evacuate the interconnecting pipe and/or any uncharged
refrigerating system part.
