WARNING: DO NOT allow liquid refrigerant to contact
eye or skin. Liquid refrigerant will freeze eye or skin
on contact. Be careful not to loosen connections in
the air conditioning circuit.
Insufficient refrigerant quantity will reduce cooling capacity of
the air conditioner. Check quantity via sight glass (2) provided
on receiver tank (1).
Inspection Procedure
1. Start the engine and run at approximately 1500 min
(rpm).
2. Turn the air conditioner switch to ON.
3. Set the blower switch to HI.
4. Set the temperature control switch to the coolest
position.
5. Check refrigerant quantity through a sight glass on the
receiver tank.
IMPORTANT: If a sign of oil oozing out of the pipe joint is
found, the refrigerant may be leaking.
If the refrigerant level is low, consult your authorized dealer.
