Section 6 Sealed System IMPORTANT The purpose of this service manual is to give the service technician an understanding of the changes in refrigerants and sealed system service. Persons attempting to use this service manual to make repairs to sealed system refrigeration systems should have electrical training as well as training in sealed system repairs. The person making the repairs must know and understand all laws (Local and International) governing handling of all refrigerants.
Section 6 Sealed System Service Diagnostic Tips A prime requisite on the initial contact is: Always allow the customer to explain the problem. Many times the trouble can be diagnosed more quickly, based on the customer’s explanation. Most of all, do not jump to conclusions until you have heard the full story and have evaluated the information obtained from the customer. Then proceed with your diagnosis.
Section 6 Sealed System Safety Warnings Wear approved safety glasses when working with or on any pressurized system or equipment. have an approved dry type fire extinguisher handy when using any type of gas operated torch. Soldering 1. All joints to be soldered must have a proper fit. Clearance between tubes to be soldered should be from .001” to .006”. It is not practical to actually measure this; however, you do not want a dry fit or loose fit.
Section 6 Sealed System Basic Components The basic components of an air conditioner are a compressor, condenser, evaporator and heat exchanger (capillary tube and suction line).
Section 6 Sealed System Compressor High pressure superheated gas Low pressure saturated gas plus absorbed heat Oil level Bulkhead Cooler drier air Inside Outside Condenser Fan Evaporator Blower Wheel Fan Motor Outside air plus rejected heat Warm moist air Evaporator Low pressure liquid minus absorbed heat Outside air at ambient temperature Condenser Restrictor Tube High pressure liquid minus absorbed heat Figure 6-2.
Section 6 Sealed System Testing for Refrigerant Leaks NOTE The line piercing valve (clamp-on type) should be used for test purposes only. It must be removed from system after it has served its purpose. If the system is diagnosed as short of refrigerant and the system has not been recently opened, there is probably a leak in the system. Adding refrigerant without first locating and repairing the leak or replacing the component will not permanently correct the difficulty. The leak must be found.
Section 6 Sealed System Installing a New Compressor Replacement of the compressor must be done in a continuous sequence so the system is exposed to the atmosphere no longer than necessary. All replacement compressors are shipped with rubber plugs in the suction and discharge tubes and contain the correct oil charge and a holding charge of inert gas. Before installing the replacement compressor, remove the discharge plug and check for the pop sound of the inert gas leaving the compressor.
Section 6 Sealed System Evaporator and Suction Line Replacement Final Leak Test 1. Disconnect electrical supply to unit. 2. Disassemble the product enough to get access to the compressor (refer to Component Removal Section). 3. Attach an approved self tapping line tap valve to the process tube. Connect refrigerant recovery system to tap valve. Turn on recovery system, open the line tap valve, and allow refrigerant to flow into an approved tank. 1.
Section 6 Sealed System To Flush The System CAUTION Use extreme care when using Dry Nitrogen to flush systems. Pressure in nitrogen cylinder could be as high as 2000 psi. Nitrogen cylinder must be equipped with approved pressure regulator and pressure relief valve. Ensure that your hoses have adequate ratings for pressure involved and that all of your equipment is in good condition. The end of the flushing hose on this tank regulator must be equipped with a hand shut-off valve (Robinair No. 40380).

Section 6 Sealed System Installing Evacuation and Recharging Equipment For Reciprocating Compressors 1. Disconnect electrical supply to unit. 2. Attach an approved self tapping line tap valve to the process tube. Connect refrigerant recovery system to tap valve. Turn on recovery system, open the line tap valve, and allow refrigerant to flow into an approved tank. 3. If compressor was replaced, install correct sized process tube adapter on process tube.
Section 6 Sealed System Charging The System CAUTION Check the serial plate for the correct refrigerant type. It is extremely important to verify the type of refrigerant in the system before starting any sealed system repairs. If a filter-drier has been added to the system, add .78 ounces of refrigerant to allow for the additional volume of the sealed system.
Section 6 Sealed System Vacuum Pump Maintenance It is absolutely essential to maintain your vacuum pump according to the manufacturer’s instructions, including required oil changes at the recommended intervals. Vacuum pump oil should always be changed after evacuating a contaminated system. Vacuum pump performance should be checked periodically with a micron gauge. Vacuum pump suppliers may or may not recommend changing the vacuum pump oil to the same type that’s in the system being evacuated.
