1.4 — Carlyle OEM Compressor Warranty Original OEM compressors are warranted to be free from defects in material and workmanship for a period of 12 months from the date of original installation, or 20 months from the date of manufacture, whichever comes first. When a service compressor is used to replace an original compressor, the remaining portion of the first-year OEM warranty is transferred to the service compressor (within the United States and Canada).
1.5 — Service Billing and Credit Returns of in-warranty parts should be made to the same Local Carlyle Distributor who supplies these replacement parts. Local Carlyle Distributors will sell parts and service compressors only to credit-approved accounts (except for cash sales). 1.6 — Green Carpet Program, Parts and Stocking Policy The Carlyle Green Carpet program is a free service created to assist users in obtaining service replacements.
on the entire system, including the Carlyle compressor. All system or compressor questions should be directed first to the OEM or the OEM’s local representative. If questions cannot be answered by the OEM or this Service Guide, please contact the Carlyle engineering group. The following recommended start-up procedure for Carlyle 06D, 06E, and 06CC compressors will help eliminate initial compressor failures caused by flooded start, floodback, and running out of oil.
BEFORE START-UP 1. Verify that the compressor nameplate indicates proper model and voltage. Do the values agree with system needs and available power? 2. Verify that there is oil in the system. Since different refrigerants (CFC, HCFC, or HFC) require specific oils (mineral, alkylbenzene, or polyolester [POE]), Carlyle ships most new and service compressors without oil. The oil level for 06CC size 16 to 37 Cfm compressors and all 06D compressors should be at 1/4 to 3/4 of the sight glass.
CAUTION CAUTION Do not add excess oil. It is especially important on the 06E and 06CC (50 to 99 Cfm) compressors that excess oil not be added to the system. Laboratory tests and field experience indicate excessive oil levels can cause blown valve plate and cylinder head gaskets, increase compressor operating temperatures, and cause oil equalization problems. !! NOTE: All 06D compressors and 06CC (16 to 37 Cfm) compressors have one sight glass on the side of the crankcase.
compressor unit configurations. This system prevents oil from building up in an 06E motor barrel during the off cycle, thereby preventing an oil slug on start-up. The line is either 1/4 in. (6 mm) or 3/8 in.(8 mm) tubing interconnecting to fittings located in the bottom of the 06E crankcases. To connect to the 06E compressor motor barrel, fitting P/N 5F20-1311 (5/8 in.-18 x 1/4 in. MPT) is recommended. Some 50 cfm compressors have a 1/4 in. NPT connection and do not require the 5F201311 fitting.
Use only Carlyle approved oil appropriate for the refrigerant being used. Sections 3.6 and 3.7 on pages 69-72 list all the approved oils. Section 3.11 on page 73 notes the correct oil pump pressure in relation to age of the compressor. 3. Leak test, evacuate, and dehydrate the system. 4. Charge the system. When initially charging the high side of the system with liquid refrigerant, all service valves should be closed (front seated).
COMPRESSOR START-UP 1. After circuit breaker and control circuit switches are placed in the ON position and the compressor starts, listen for unusual sounds. If unusual sounds are heard, shut down the compressor, investigate the cause, and correct. Possible problems are: • excessive vibration • excessive oil • liquid slugging • low oil 2. After the compressor has run 10 to 15 minutes and no liquid floodback is evident, completely open suction service valve.
(liter) of additional oil per compressor. The amount to be added will vary depending on the system, but keeping the oil level between 1/8 and 3/8 level in the sight glass will eliminate the chance of excessive oil charges. CAUTION Adding excessive oil to the 06E and 06CC (50 to 99 cfm) compressors can cause blown gasket problems.

2.3 — Troubleshooting Procedures ! DANGER Before attempting service work on the compressor, the following safety precautions must be strictly observed. Failure to follow these instructions could result in serious personal injury or death. See Warning Label. Follow recognized safety practices and wear protective goggles. Do not operate compressor or provide electric power to this unit unless the compressor terminal box cover is in place and secured.
COMPRESSOR ISOLATION If you have determined there is no refrigerant leak around the terminals and the compressor must be replaced, proceed beginning with Step 1: 1. Shut off suction and discharge service valves to isolate compressor and slowly remove all refrigerant in compressor. Appropriate service practices should be followed to properly reclaim refrigerant removed from the compressor. 2. Disconnect all electrical wiring to compressor. 3. Unbolt suction and discharge service valves from compressor.

2.4 — Service Procedures The service section covers replacement of valve plates and gaskets, service to the bearing head assembly containing the oil pump, and a clean-up procedure to follow in case of motor burn out. Most other internal service requires replacement of the compressor. REMOVE, INSPECT AND REPLACE CYLINDER HEAD AND VALVE PLATE ASSEMBLY To test for leaking discharge valves or blown cylinder head or valve plate gaskets: 1. Pump compressor down. 2.
DISASSEMBLY 1. Disassemble cylinder heads by first loosening cylinder head bolts. Leave at least 2 bolts partially threaded to prevent any problems if refrigerant is accidentally left in the compressor under pressure. To separate the cylinder head from the valve plate, pry up between the head and valve plate. When the cylinder head is separated from the compressor body remove the last threaded bolts. ! CAUTION Do not hit the cylinder head to break it free of the valve plate.
Fig. 2 –– Disassembly of Valve Plate (Standard Efficiency Valve Plate Shown) 4. Pry up along sides of valve plate to remove valve plate from crankcase. This provides access to suction reed valves (see Fig. 3). Remove suction valves from dowel pins. On 06D and 06CC (16 to 37 Cfm) compressors, also remove the suction valve positioning springs (see Fig. 4). 5. Inspect components for wear or damage. If replacement is necessary, replace as a complete assembly. Individual parts must not be interchanged.
Fig. 3 –– Valve Plate Removed (06E Refrigeration Valve Plate Shown) Fig.
REASSEMBLY 1. If reassembling existing components, do not interchange valves or turn them over. They must be reassembled in their original position. Install the suction valve positioning springs (06CC size 16 to 37 Cfm and 06D compressors only) on dowel pins. Assemble positioning springs with spring ends bearing against cylinder deck (Fig. 4), spring bow upward. 2. Install suction valve on dowel pins as follows: a.
3. Install new valve plate gasket. Using proper hold-down torque will prevent leaks. a. Fiber gaskets can be installed dry or lightly oiled. Do not soak gaskets in oil. If an oil-soaked gasket is overheated, it will bind to the metal, making the valve plate and/or the head difficult to remove. b. Metal gaskets must be installed dry. 4. Place valve plate on cylinder deck. 5. Install cylinder head gasket.
7. Certain high compression ratio applications develop high discharge gas temperatures which may cause the cylinder head and fiber valve plate gaskets to develop a set. Under these conditions the cap screws may lose hold-down torque. It is recommended that all gear cap screws be re-torqued 24 hours after new fiber gaskets are installed. NOTE: Compressors with metal core gaskets do not require re-torque.
Fig. 6 –– Removing Pump End Bearing Head (06D Compressor) 1. a. To disassemble, first remove four (4) cap screws from the bearing head cover plate and remove the oil feed guide vane and spring. b. Remove the two (2) drive segment cap screws from the end of the crankshaft (see Fig. 6 and Fig. 7). These screws must be removed before the bearing head can be removed. 2. Remove the eight (8) cap screws holding the bearing head assembly to the crankcase. Remove the bearing head assembly by pulling forward.
Fig. 7 –– Removing Pump End Bearing Head (06E Compressor) 3. Inspect the bearing surfaces for evidence of wear or damage. If bearing surface is worn or scored, or if the oil pump is defective, the complete bearing head must be replaced (see replacement bearing head package listed below).
4. To reassemble, bolt the bearing head to the crankcase. Bolt torque: • 06CC, 16 to 37 Cfm, and all 06D: 30 to 35 ft-lb. (40 to 48 Nm) • 06CC, 50 to 99 Cfm, and all 06E: 55 to 60 ft-lb. (75 to 81 Nm) 5. Bolt the drive segment (replace if worn) to the crankshaft. Bolt torque: • No. 10 Screw: 4 to 6 ft-lb. (5 to 8 Nm) • 1.4 in. (6 mm) screw: 12 to 15 ft-lb. (16 to 20 Nm) IMPORTANT: The 1/4 in. snorkle tube should face away from the crankshaft (Fig. 6). 6.
MOTOR BURNOUT CLEAN-UP PROCEDURE When a hermetic motor burns out, the stator winding decomposes and forms carbon, water, and acid, which contaminate refrigerant systems. These contaminants must be removed from the system to prevent repeat motor failures. See Carlyle/Carrier recommendation procedures for cleanup after burnout in semi-hermetic compressors - form #06DA604782. ! WARNING Before attempting service work on the compressor, see safety precautions listed in Section 2.
should be thoroughly cleaned or replaced before connecting to replacement compressor. 4. Install new liquid line filter-drier. If the system has a suction line filter-drier, replace the core. 5. Evacuate and dehydrate replacement compressor. Ensure oil in compressor is at the proper level. NOTE: Since most new and service compressors are now shipped without oil in the crankcase, you must check to see if there is oil. Adding or charging oil is usually easier prior to installing the compressor.

3.4 — 06D, E High Efficiency (H.E.) Compressors High efficiency compressors were phased in between 1985 and 1987. A high efficiency compressor can be identified as follows: All 06D H.E. compressors (new or service replacement) have the number “3” in the 11th digit of the model number. See page 3 for examples. The 06E compressor model numbers did not change. To determine if a 06E compressor is high efficiency, check the serial number.
from the air) and should be added just prior to system start-up only. See Section 2.2, page 11 for Carlyle approved system start-up instructions and Section 3.6 below for the proper refrigerant oils. 3.6 — Refrigerants and Oils for 06D, E Compressors The introduction of HFC/POE systems has led to confusion as to what refrigerants and oils are approved for use in Carlyle compressors. For 06CC compressors, see Section 3.7, page 72.
FOR HCFC BLENDS: Carlyle’s engineering efforts were directed toward testing the new HFC refrigerants, not the interim HCFC blends. Carlyle provides tentative approvals of the following blends based on tests by the refrigerant manufacturer and feedback from field applications, not on testing undertaken by Carlyle: • For Low Temperature applications: R-402A (HP-80) and R408A (FX10). • For Medium Temperature applications: R-401A (MP-39), R-402B (HP-81) and R409A (FX56).
FOR HFCs: Carlyle has approved R-134a, R404A, R-507, and R-407C. The following POLYOL-ESTER (POE) are approved oils for HFCs: Totaline® (see Note 5).......P903-1001, 1701 Castrol..(see Note 5) ............................

3.7 — Refrigerants and Oils for 06CC Compressors All 06CC compressors are approved for R-22, R-404A and R-507 except compressors in the 16 to 37 Cfm range. Compressors in this size range cannot be used with R-404A and R-507 prior to Serial No. 2099J ---without installing a retrofit compressor valveplate (Part No. 06CY660-002) kit. See Section 3.6 on page 69 for further information about refrigerants and oils. See Section 3.6 on page 71 for the correct oil for each refrigerant.
3.10 — Oil Additives No oil additive is allowed without written approval from the Carlyle Engineering Department. The use of any unauthorized additive will void the warranty. 3.11 — Oil Pressure All new 06D, E, CC compressors are supplied with oil safety switch connections. Carlyle has introduced a new high flow oil pump and changed oil pressure specifications due to changes in lubricants and refrigerants.
3.12 — High Flow Oil Pump (Bearing Head) Carlyle introduced a new high flow oil pump to provide improved lubrication with the new HFC refrigerants and POE lubricants. The pump is a durable, automatically reversible, high flow design. The high flow design improves lubrication, especially with the new HFC/POE combination, and provides improved lubrication in the case of a flooded start. This oil pump is standard on all new and service compressors. See Section 3.11 above for details on oil pressure.
3.14 — Oil Safety Switch Carlyle uses as standard the 120-second time delay oil safety switch, as this time period is preferred for HFC/ POE systems. This is a change from the 45 to 60-second time delay used previously with CFC and HCFC systems. It is not necessary to change out the older, shorter time delay switch unless the unit is converted to an HFC/POE system. The oil safety switch protects the compressor when lubrication is lost for more than 120 seconds.
Use of an oil safety switch is recommended/required by Carlyle as noted in the chart below: TYPE OF SYSTEM USING 06D COMPRESSORS USING 06E COMPRESSORS USING 06CC COMPRESSORS Single Compressor without Unloading Recommended Required Required Single Compressor with Unloading Recommended Required N/A Multiple Compressors without Unloading Required Required Required Multiple Compressors with Unloading Required Required N/A 3.
When the discharge gas temperature in the cylinder head exceeds the sensor trip setting (see below), the sensor will open the control circuit and shut off the compressor. The head sensor must be wired into the control circuit by the OEM and is pilot duty only at 240V = 0.52A, at 115V = 1.04A. The sensors are threaded into the head without a well. Therefore, when changing a sensor, the compressor must first be isolated and evacuated.
below 0°F (-18°C) and all R404A/507 single stage applications below -20°F (-29°C). A cylinder head cooling fan is recommended (but not required) for any two-stage (Compound Cooling) applications down to -40°F (-40°C).

3.19 — Crankcase Heater Data Crankcase heaters help reduce refrigerant migration to the compressor during shut-down. Crankcase heaters are designed to raise the temperature in the compressor oil compartment approximately 15 to 25°F (8 to 14°C). Carlyle recommends crankcase heaters be wired so the heater is energized only when the compressor shuts off. Crankcase heaters should be “ON” initially for 24 hours before starting the compressor. All HFC/POE applications require a crankcase heater.
3.20 — Compressor Mounting Data Mounting packages are available to mount individual compressors. Package contains mounting springs, threaded studs, snubbers, spring cups, nuts, and washers for (1) compressor.

4.11 — Voltage and Current Unbalance VOLTAGE UNBALANCE (Maximum 2%) Voltage unbalance can cause motors to overheat and fail. Below is the recommended method for determining voltage unbalance. Example: Supply voltage is 240-3-60 AB = 243 volts BC = 236 volts AC = 238 volts 243 + 236 + 238 3 = 717 3 = 239 volts Average Voltage = Determine maximum deviation from average voltage: (AB) 243 – 239 = 4 volts (BC) 239 – 236 = 3 volts (AC) 239 – 238 = 1 volt Maximum deviation is 4 volts.
CURRENT UNBALANCE (Maximum 10%) Voltage unbalance will cause a current unbalance, but a current unbalance does not necessarily mean that a voltage unbalance exists. A loose terminal connection or a build-up of dirt or carbon on one set of contacts (using the example of L1 as the problem leg) would cause a higher resistance on that leg (L1) than on L2 and L3. The current follows the path of least resistance, so the current increases in legs L2 and L3.
