Products, Inc. CR-182-10 System Service Manual 21-50-03 Page 1 April 5, 2002 COMPRESSOR DESCRIPTION AND OPERATION 1. GENERAL The compressor is mounted on brackets in the engine compartment and is driven by a belt running to the starter ring-gear pulley. The compressor compresses the refrigerant gas for condensing at ambient temperatures and pumps the refrigerant through the system. The compressor clutch is powered by 28 VDC. This section of the maintenance manual discusses maintenance practices used for the compressor assembly portion of the air-conditioning system. COMPRESSOR INSTALLATION
Products, Inc. CR-182-10 System Service Manual 21-50-03 Page 201 April 5, 2002 COMPRESSOR MAINTENANCE PRACTICES 1. GENERAL The following procedures are used to perform typical maintenance on the compressor assembly. 2. TOOLS AND EQUIPMENT DESIGNATION REF. NO. QTY. REMARKS Polyolester oil Comm Avail A/R Viscosity ISO 68 3. COMPRESSOR ASSEMBLY MAINTENANCE PROCEDURES A. Compressor drive belt adjustment: 1. Adjust belt for moderate tension and then rotate large pulley through 2 revolutions. 2. Tension belt to deflect 0.25 inch with a 10 lb. force applied at mid- span location. The belt should deflect .5 inches with a 22 lb force applied at the mid-span location. 3. Rotate belt 5 revolutions. Re-tension as required. 4. Cessna alternator belt adjustment procedures should always take precedence over any recommendations here within. B. Compressor oil level check: NOTE: It is not necessary to check the compressor oil level at any time during routine maintenance as long as servicing instructions are properly followed. The compressor comes equipped with 5 oz. of polyolester oil viscosity grade ISO 68. If the amount of oil removed during system discharging and vacuuming is always added before charging, oil never needs to be added to the compressor.
Products, Inc. CR-182-10 System Service Manual 21-50-04 Page 1 April 5, 2002 CONDENSER DESCRIPTION AND OPERATION 1. GENERAL The condenser assembly is located in the tailcone and is attached to support structure mounted to frames in the aircraft. The assembly consists of a condenser coil unit and shroud with associated brackets. The condenser converts the refrigerant from a gas to a liquid. The receiver/drier bottle removes moisture from the refrigerant. The condenser fan draws in cool (ambient) air from the intake duct on the left side of the aircraft and blows this air through the condenser coil where the refrigerant gas can be condensed to a liquid. The air is then exhausted overboard through the exhaust duct on the right side of the tailcone. This section of the maintenance manual discusses maintenance practices used for the condenser assembly portion of the air-conditioning system.
Products, Inc. CR-182-10 System Service Manual 21-50-04 Page 201 April 5, 2002 CONDENSER MAINTENANCE PRACTICES 1. GENERAL The following procedures are used to perform typical maintenance on the condenser assembly. 2. TOOLS AND EQUIPMENT DESIGNATION REF. NO. QTY. REMARKS Vacuum Cleaner Comm Avail 1 None Coil Cleaner Comm Avail A/R Non-acid based 3. CONDENSER ASSEMBLY MAINTENANCE PROCEDURES A. Condenser coil cleaning procedure: 1. Remove condenser coil from aircraft and use vacuum cleaner to remove large debris from upstream and downstream coil faces. 2. Spray coil cleaner on both coil faces. Wash off with water (ends capped if not installed). 3. Allow coil to dry thoroughly prior to additional maintenance.
Products, Inc. CR-182-10 System Service Manual 21-50-05 Page 1 April 5, 2002 EVAPORATOR DESCRIPTION AND OPERATION 1. GENERAL The evaporator assemblies are mounted aft of the cabin on the right side of the aircraft. The evaporator assemblies are made up of an evaporator coil, and blower. Cabin air is pulled through the evaporator coil, cooled and then distributed back to the cabin. This section of the maintenance manual discusses maintenance practices used for the evaporator assembly portion of the air-conditioning system.
