result in fire, or the formation of a
harmful gas.
Turn off any combustible heating
devices, ventilate the room, and
contact the dealer where you
purchased the unit.
Do NOT use the unit until a service
person confirms that the part from
which the refrigerant leaked has been
repaired.

means to accelerate the defrosting
process other than those
recommended by the manufacturer.
