- Page 2 WARNING: Read all procedures and warnings prior to performing maintenance! For your safety, it is essential that you use properly sized and operating test equipment. WARNING: Air conditioning and refrigeration systems are pressurized; hazards could exist resulting in personal injury. It is therefore recommended that the following steps for troubleshooting, removal and installation of the hermetic compressor be performed by qualified experienced personnel only.

VERIFY PROPER APPLICATION. Verify that the compressor being replaced and the Bristol compressor have a like capacity for the refrigerant being used and that the voltage and frequency characteristics are the same. - Page 4 INSTALL FILTER DRIERS. Bristol Compressors recommends the use of new adequately sized liquid and suc- tion line driers anytime a compressor is replaced. If the new compressor is to be used to replace a compressor with a burned motor, the use of a high acid neutralizing filter drier is recommended.
- Page 5 CHECK THE ELECTRICAL SYSTEM. While the system is evacuating, connect the electrical leads to the com- pressor terminals. Verify that the electrical system is wired according to the unit’s manufacturer and Bristol’s wir- ing diagram on page 9. Verify that the electrical components match those specified on the compressor electrical data sheet on pages 14 through 30.

HEAT PUMP STEP 1: Operate system in the heating mode with outdoor fan disconnected. STEP 2: Run system until the designed winter condition in your area is reached (may need to cover coil for this test).
- Page 8 CHECK FILTER DRIERS FOR CONTAMINATION. Suction Line Filter: If internal contamination is heavy, the suction line filter drier may become clogged and ineffective. Check the pressure drop across the filter drier after approximately 8 hours running time and, if it exceeds 2 psig, replace. Liquid Line Filter: Always replace the original equipment liquid line filter drier(s).

SINGLE PHASE WIRING DIAGRAMS SINGLE PHASE WIRING DIAGRAMS SINGLE PHASE WIRING DIAGRAMS SINGLE PHASE WIRING DIAGRAMS START ASSIST—CAPACITOR START/CAPACITOR RUN (CSCR) Use this diagram on systems with expansion valve and systems that do not allow pressure equalization prior to compressor start. NOTE: WHEN CRANKCASE HEATER IS USED, CONNECT TO INCOMING POWER LINE SO THAT HEATER IS ENERGIZED CONTINUOUSLY. - Page 10 (H2*J**B). These “Bleed” compressors are designed to internally equalize by utilizing an external check valve in conjunction with a non-bleed type TXV. Bristol recommends the check valve to be installed on the compressor’s discharge connector tube (or as close as possible) in order to minimize pressure equalization time across the compressor valves.
- Page 11 The required time for internal compressor equalization depends on the specific pressure differential when the compressor cycles off. To assure pressure equalization, Bristol Compres- sors recommends a minimum of five minute anti-short-cycle delay. However, if muffler with integral check valve combinations with larger volumes than noted in Table 4 are employed, a longer time delay may be needed to assure equalized pressure at start up.

Page 13: Important Notes
• If components other than those recommended in Tables 2, 3 and 4 are utilized, Bristol advises the use of a high quality, non-positional check valve designed for near-zero leak rates. The muffler and check valve must be UL/CSA certified for use as high side components for the intended refrigerant application. - Page 14 REFRIGERATION/AIR CONDITIONING AND HEAT PUMP ELECTRICAL COMPONENTS PARTS FOR SINGLE PHASE COMPRESSORS H20J SERIES 60 Hz Voltage Capacitors Potential Relays Compressor Phase Start Mars µfd/Volts µfd/Volts Model Number 3ARR3 6-Pak PTCR Starter H20J153ABC 230/208-1-60 30/370 145-175/250 16048 Optional H20J173ABC 230/208-1-60 30/370 145-175/250 16048...
