[8] CHECKING AND SERVICING AIR-CONDITONER
[INSPECTING THE AIR-CONDITIONING UNITS]
Users (possessors) of the Machine are obligated to conduct periodic inspections by the
Fluorocarbon Refrigerants Emission Regulating Act.
Inspect once every three months. Even when the air-conditioner is not used during off season,
the inspection is required.
Check Item
・
Abnormal vibration and abnormal operation noise of the compressor
・
Oil oozing out on and around the compressor
・
Scratches, corrosion, rust and other blemishes on the compressor
・
Frosting of air-conditioner heat-exchanger in the cabin.
[CHECKING THE QUANTITY OF REFRIGERANT (GAS)]
·
If the refrigerant of air-conditioner gets into the eyes, loss of sight may occur and if it
comes into contact with skin, it gives rise to a frostbite. Never touch the refrigerant. Do
not loosen any parts within the refrigerant circuit.
·
In an area where refrigerant is leaking, never bring fire into the area.
If any shortage of refrigerant (gas) is found, be sure to identify the spot of its leakage
and repair it. Also, when replenishing refrigerant, the replenishing work must be
consigned to a Class 1 fluorocarbon refrigerants filling and recovering contractor
registered by the competent authorities in accordance with the Fluorocarbon
Refrigerants Emission Regulating Act, and have a replenishment certificate issued by
the contractor and file it at the user's office.
Shortage of the refrigerant (gas) affects the cooling
performance.
While the engine is running at full revolution speed for
operating the air-conditioner at a high speed, check the
state of refrigerant gas (R134a) flowing in the refrigerant
circuit by viewing it through sight glass (1) (inspection
window).
・
(A) No air bubble is included in the flow: Normal
・
(B) Air bubbles are included in the flow (air bubbles
pass continuously): The refrigerant is insufficient.
・
(C) Colorless and transparent: No refrigerant
NOTES
When air bubbles are generated, the refrigerant is
insufficient and thus needs repair. Refill the refrigerant.
Consign the refilling to a Class 1 fluorocarbon refrigerants
filling and recovering contractor registered by the
competent authorities.
[KEEPING THE MAINTENANCE RECORD]
Keep the records of administrator's name, location of the machine, initial amount of Freon filled,
and dates of inspection, repair, refrigerant recovery, and refrigerant filling until the machine is
disposed of.
