EXPLANATION OF COMPONENTS OPERATION
3-52
REMARK
The replacement interval may become shorter depending on the conditions during use.
If the receiver is used when the moisture absorption limit of the desiccant has been exceeded, the refrigerant cir-
cuit may become blocked and cause the compressor to break down.
PRECAUTIONS WHEN REPLACING RECEIVER
q 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.
q When removing the refrigerant from the refrigerant circuit, release it gradually from the low pressure side to
prevent oil from flowing out.
CHECK COMPRESSOR BELT TENSION AND REFRIGERANT (GAS) LEVEL 3
If the compressor belt is loose, or the refrigerant level is low, cooling is not carried out efficiently.
For details, see “WHEN REQUIRED (4-21)“.
CLEANING AIR FILTER 3
If the air filter for the FRESH or RECIRC air intake becomes clogged, the cooling or heating capacity will drop.
To prevent this, clean the air filter with compressed air once a week.
For details of the cleaning method, see “WHEN REQUIRED (4-21)“.
