If there is a lack of refrigerant, the cooling performance will be
poor.
When operating the cooler at high speed, there should be no
bubbles in the sight glass (inspection window) mounted on the
condenser unit receiver.
If there are any bubbles, there is a lack of gas, so have to add
refrigerant at a shop.

The refrigerant used in the cooler is colorless and odorless, and
However if it
gets in the eyes or on the hands, it will be cause of frostbite or
loss of sight, so never loosen any part of the refrigerant circuit.
Check during off-season
When the air conditioner is not being used, run the compressor
at low speed for a few minutes every week to avoid loss of oil. (Run
the engine at low speed with the cooler temperature regulator knob
at LOW COOL.)
In cold weather, do not run the compressor suddenly at high
speed. This may cause failure in the compressor. When the
temperature is below 2 to 6.5”C, the low pressure cut-off switch
functions to stop the compressor from running even when the air
conditioner switch is pressed.
