HVAC 37 Following table illustrates the amount of oil to be replenished for respective HVAC/AC com- ponents Replaced part Amount of compressor oil to be replenished (in CC) Evaporator 25 Condenser 40 Hoses 10 Pipes 10 NOTE When only charging refrigerant without replacing any component, replenish the same amount of measured oil when recovering refrigerant, if not measured, re- plenish 30cc oil. iv. PRESSURE TEST USING MANIFOLDGAUGES This is a method where trouble is detected and re- paired by using manifold gauge. The manifold gauge indicates the refrigeration cycle high and low pres- sure side pressures on the respective gauge. NOTE Make sure following conditions are fulfilled before getting the correct gauge readings (after engine has warmed –up ) Engine speed 1500 rpm A/C inlet temperature (Ambient Temperature) 30° - 35° C (86° - 95° F) Blower speed High Temperature Control Full cold Reference value be- fore AC operation at both high and low pressure sides 5-8 kg / cm 2 (0.5 - 0.8 MPa)
