wheel' and the excess pressure will be dissipated through the
expansion valve. When the pressure drops below 27.6 bar,
the safety valve will close again and the compressor will be
operative.
The terms ‘high’ and ‘low’ pressure (or side) refer to the
pressure differential between the compressor and expansion
valve ports. This differential is critical to system fault
diagnosis and efficiency checks.
The high side starts at the compressor and includes the
trinary switch, condenser, receiver drier and expansion
valve.
The low side starts at the expansion valve outlet and includes
the evaporator and all connectio ns back to the compressor.
The trinary switch (6) monitors system pressure between the
compressor and condenser. If the pressure rises above 30
bar or falls below 2 bar the compressor clutch is
de-energised to prevent damage to system components.

Leaks
Faults associated with low refrigerant charge weight and low pressure may be caused by leakage. Leaks traced to
mechanical connections may be caused by torque relaxation or joint face contamination. Evidence of oil around such
areas is an indicator of leakage.
Leak Detection
Fluorescent Tracer Dye - A fluorescent tracer dye is incorporated into th e refrigeration system and can be checked for
non-apparent leaks by scanning with a high intensity ultraviolet lamp. The location of leaks can be pinpointed by the bright
yellow glow of the tracer dye.
Automatic Refrigerant Leak Detector - (various manufacturers) Hand-held, portable, battery operated leak detector.
Place in and around A/C system to detect refrigerant leaks.
System Pressure Fault Classification
This table should be used in conjunction with the graphical representations of 'High side' pressure / ambient temperature
and 'Low side' pressure / evaporator temperature. Caution
Observe ALL safety precautions associ ated with ultraviolet equipment.
If erratic or unusual gauge movements occur, check the equipment against known Recovery / Recycling / Recharging unit
gauges.
