PROCEDURE FOR REPLACING RECEIVER
Replace the receiver once every two years.
After replacing the receiver, add compressor oil. Turn the receiver at an angle and measure the oil remaining
inside the receiver, then add the same amount of oil (Denso Oil 6) to fill the receiver.
REMARK
● Depending on the condition of use, the replacement interval may be shorter.
● If the receiver is used when the desiccant has exceeded the water absorption limit, the refrigerant circuit may
become clogged and cause failure of the compressor.
PRECAUTIONS WHEN REPLACEING RECEIVER
● If the receiver is left for more than 15 minutes with the blind cover removed, the moisture in the air will be
absorbed, and this will reduce the life of the desiccant. If you remove the blind cover, connect the piping
quickly, evacuate the system and fill with refrigerant.
● When removing the refrigerant from the refrigerant circuit, release it gradually from the low pressure side to
prevent oil from flowing out.
CREANING AIR FILTER
If the air filter for the FRESH or RECIRC air intake becomes clogged, the cooling or heating capacity will drop. In
places where there is a lot of dust, clean the air with compressed air once a week. For details of the cleaning
method, see "CLEAN AIR CONDITIONER AIR FILTER (FRESH/RECIRC FILTER) (PAGE 4-48)".
