3. Checking the air conditioning system.
①
Economic friendly refrigerant : R134a 0.7
∼
0.85Kg.
The presence of air and water in the system could jeopardize its efficiency.
-The air is uselessly compressed by the compressor and no cooling effect is produced.
-The moisture has a tendency rise to obstructions which prevent the cooling efficiency.
②
Check belt tension ; when finger pressure is applied to the mid-point between both pulleys.
③
Condenser fins must always be duly clean using water or an air set.
4. Checking the air conditioning system charge
(1) Check the refrigerant charge.
A.Run the engine at 1500rpm
B. Set the air conditioning system in the coldest for 5 minutes.
C. Check sight glass for clear sight or cloudy
Caution
If the air conditioning system is operated without being charged, The lubrication in the
compressor can cause damage.
(2) Check the refrigerant with receive drier sight glass
Bubbles or foam visible
