WARNING: Do not attempt to loosen connections
in air conditioning circuit when the air conditioner
malfunctions. Doing so may cause high pressure gas
to spout, resulting in serious injury. Consult your
authorized dealer immediately.
1. Preseason maintenance
Prior to the season, consult your authorized dealer for
maintenance of the air conditioner in order to operate it
in good condition during the season.
This maintenance includes replenishment of refrigerant,
inspection and replacing (if necessary) of circulating and
fresh air filters, line connections, pressure switches and
inspection and cleaning of evaporator.
2. Off-season maintenance
(1) Operate the compressor once a week at low speed
for several minutes in order to maintain its parts in
well lubricated condition. Be sure to run the engine
at slow idle and place the temperature control switch
in MEDIUM COOL. This operation also prevents
refrigerant leakage caused by dried up shaft seal.
(2) Check for refrigerant leakage. If the refrigerant level
is low during off-season, rust will be formed inside
the circuit.
IMPORTANT: Do not remove V-belt from the compressor
during off-season.
