PERFORMANCE ORDER
1. Check condenser plates on lack of a contamination and damage. If plates are hammered, clear them a water stream under pressure.
Prevention

Be careful not to damage a plate.
2. Be convinced that the belt of a drive of the compressor of the conditioner is established correctly.
3. Check a tension of a belt of a drive of the compressor of the conditioner. If the belt slips on pulleys, productivity of central air of air and belt service life will decrease.
To avoid it, it is necessary to observe the following procedure of service of a belt:

– any belt which worked not less than 30 mines, is considered the used belt;
– check a belt tension in the ordered intervals of service.

Check a belt tension, having pressed on it effort of 98 N in a place located on identical removal from pulleys, and measure a belt deflection.

Deflection of a belt of a drive of the compressor of the conditioner at tension check:
After belt work: 8 mm
The used belt: 6–7 mm
New belt: 5–5,5 mm
4. Start the engine.
5. Include air central air, having pressed the A/C switch. Check work of central air of air in all positions of the switch of operating modes of the fan.
6. Check operation of the electromagnetic coupling.
7. Check frequency of rotation of a cranked shaft of the engine idling. At turning on of the electromagnetic coupling frequency of rotation of a cranked shaft of the engine should increase.
8. Check operation of the fan of the condenser.
9. If cooling is absent or it is not enough of it, check air central air on leaks.
