Carlyle Compressor Reciprocating Compressor 06DA8182

Warning: This inspection requires trained personnel with PPE!

After 2 to 4 hours of operation, inspect compressor oil for discoloration and/or acidity.

Does the oil show signs of contamination?

If oil shows signs of contamination, replace oil and filter-driers and clean the suction strainer.

NOTE: When testing for moisture and acidity, be sure the test kit used is appropriate for the refrigerant (CFC, HCFC, or HFC) and the oil (mineral, alkylbenzene, or POE) in the system.

Select the type of refrigerant used

Carrier’s Total Test Kit is accurate for CFC and HCFC air-conditioning applications. If used with POE oils, Total Test Kit will indicate acid, but is not an accurate indicator of moisture.

Sign off on the initial 2 hours motor inspection

Warning: This procedure requires trained personnel with PPE!

Does the oil pump require replacement?

Does the bearing require replacement?

Enter the part number for replacement

Note: The above pump end bearing head packages include a bearing head with the high side oil safety switch connection. This pump is recommended for all CFC, HCFC, and HFC refrigeration applications.

REMOVE, INSPECT AND REPLACE CYLINDER HEAD AND VALVE PLATE ASSEMBLY

Observe suction and discharge pressure equalization.

If valves are leaking or a gasket is blown, the pressure will equalize rapidly.

Maximum allowable discharge pressure drop is 3 psi per minute after initial drop of 10 to 15 psi in first half minute.

New reed valves may require 24 to 48 hour run-in time to seat completely.

A compressor bank (head) with a blown gasket can also usually be detected by touch since the head temperature will normally be much hotter than a bank with good gaskets.

If there is an indication of loss of capacity and discharge valves are functioning properly, remove valve plate assembly and inspect suction valves.

NOTE: This test procedure is not applicable to compressors equipped with pressure actuated unloader valves due to rapid pressure equalization rate. Inspect suction and discharge valves by disassembling valve plate.

Warning: This procedure requires trained personnel with PPE!

Is the application high compression ratio?

If not, skip the re-torque procedure

Are new fiber gaskets installed?

If not, skip the re-torque procedure

Does the compressor have metal core gaskets?

If yes, skip the re-torque procedure

Did the gear cap screws hold down torque after 24 hours?

Sign off on the gear cap screws maintenance

Warning: This maintenance check requires trained personnel with PPE!
