ALWAYS MEASURE START WINDING CURRENT ON START-UP!
NORMALLY 2 to 10 AMPS (See Page 5 for Details)
AND
BEFORE A SUSPECT COMPRESSOR IS REMOVED, ALWAYS
CHECK LOCKED ROTOR PULL-DOWN VOLTAGE
(See Page 2 for Details)
CAUTION: Bristol compressors are completely interchangeable with other
manufacturers. However, electrical specifications, tubing configurations,
and wiring connections may vary. Before installing and starting this
compressor, you must review the wiring diagrams and check for correct
electrical components.

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.
INSTALLATION PROCEDURES AFTER COMPRESSOR HAS BEEN VERIFIED AS FAULTY…
BEFORE CONDEMNING A SINGLE-PHASE COMPRESSOR THAT FAILS TO START…
1. Verify all following components are OK:
A. Run capacitor
B. Starting components (even if not originally installed, start assist should be tried before going to step 2)
C. Contactor
D. Winding resistance within manufacturer’s specification (assure compressor is cool to the touch)
E. Compressor not grounded via ohmmeter/Megger, etc.
F. Compressor power terminals are tight and secure
G. Check for hot spots in system wiring (wire insulation melted, connectors, insulators melted, etc.)
2. Verify locked rotor pull-down voltage (LRPDV). Always check LRPDV before removing the old or new
replacement compressor. If the LRPDV reduces the supply voltage to the compressor below the
“guaranteed to start” voltage of the compressor (single-phase 230/208 LRPDV is 197v), the power supply
must be corrected before removing the compressor.
Procedure to check for LRPDV: Warning! Make sure system is properly grounded before
proceeding!
A. Connect a voltmeter to the common terminal and run terminal of the compressor.
B. Remove the start wire from the compressor and insulate the connector lead wire.
C. Terminal cover and retainer MUST be installed before applying voltage. (See warning on page 4.)
D. Apply voltage to the compressor and measure the voltage as the compressor attempts to start (during
locked rotor). If internal overload trips, allow time for reset before continuing.
E. If the voltage at the compressor terminals does not pull down below the LRPDV, reconnect the start
wire and try to start again. If the compressor does not start, proceed to step 3 below.
3. Direct wiring. This wiring eliminates all other components and system wiring.
A. Hard-wire from a fused disconnect to the Cand Rterminals of the compressor
B. Wire in a new run capacitor from the Sterminal to the Rterminal at the compressor using new wire
leads (see page 9 permanent split capacitor-wiring diagram)
C. Turn on disconnect, verify LRPDV and measure start winding current (see item 10, page 5)
D. If compressor does not start, add a two-wire start assist kit in parallel with the run capacitor and repeat
step 3 (C). If the pressures are equalized and the LRPDV and start current are OK, and the
compressor still does not start, it is definitely faulty.
The following instructions are general in nature but include major points of consideration that will ensure proper
installation and protect you from possible personal injury. Please use this as a checklist, taking each item in its order
before proceeding to the next. If more information is required, please call Bristol Compressors’ Service Department.
1. 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. Consult your wholesaler if you have any questions about proper compressor application.
WARNING: Never use oxygen to pressurize a refrigeration or air conditioning system.
Oxygen can explode on contact with oil and could cause personal injury. When using high
pressure gas such as nitrogen or CO2for this purpose, be sure to use a regulator that can
control the pressure down to 1 or 2 psig.
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.

2. DETERMINE CAUSE OF INITIAL FAILURE. In order to prevent a second failure, the cause of the
original failure must be determined. Identify the cause and make the necessary repairs.
A. BEFORE REMOVING THE FAULTY COMPRESSOR: Remove refrigerant charge using proper
recovery procedures. Call 1-800-441-9450 for the name of the nearest Dupont authorized distributor,
or 1-800-631-8138 for Genetron Representative or 1-800-ASK-KLEA (ICI) for information on
refrigerant reclaim programs.
B. Remove the electrical leads from the compressor. Note and label the terminal to which each wire is
connected.
C. During the next operation, the access ports should be open so that pressure does not build up in the
system. Use a high temperature torch to sweat the suction line and the discharge line loose from the
compressor.
D. Remove the faulty compressor.
E. Assure excessive oil does not remain in the system. Measure oil in the failed compressor and,
if oil is low, flush excess from system (or see alternative below).
Good indicators of excess oil are: violent vibration and/or high variable sound as the extra oil moves
through the system.
Alternatives: If the excess oil cannot be flushed from the system, the last alternative is to reduce the
oil charge in the new compressor by the amount left in the system.
•This procedure should be used only if the following are true:
-The oil remaining in the system is dry (i.e., system had not leaked down)
-Oil type is same as in the replacement compressor
-Compressor failure was not a motor burnout
-The oil remaining in the system is less than 50% of the original oil charge
-Suction filter drier must be installed
•Procedure if failed compressor has lost more than 50% of the original oil charge
-Operate new compressor for 15 minutes in cooling mode (30 minutes if a suction line
accumulator is installed)
-Recover refrigerant and remove the compressor
-Remove oil from the compressor and recharge with fresh oil per the manufacturer’s
specifications
E. Remove the faulty compressor.
CAUTION: The compressor may contain harmful acids be sure to handle with extreme care using
proper protection equipment. After confirming oil charge level, return oil to compressor and install
suction and discharge rotalock caps. Copper tube fittings should be brazed closed. This is needed to
prevent further contamination of the compressor and to prevent spillage from the compressor.
3. MOUNT THE NEW COMPRESSOR. Do not remove dust cover or rubber shipping plugs until all other
connections have been completed (i.e., filters installed and all tubing changes made see steps 4, 5 and
6). Compressor should not be open to the atmosphere for more than 15 minutes. Be sure to use the new
mounting grommets that were shipped with the compressor. If the mounting sleeves shipped with the
compressor are used, the mounting bolts will bottom out when tight. Use care not to over-compress the
mounting grommets when the mounting sleeves cannot be used.
4. INSTALL FILTER DRIERS. Bristol Compressors recommends the use of new adequately sized liquid and
suction 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. For heat
pumps, a suction filter drier must be installed between the accumulator and the compressor suction
WARNING: To avoid electrical shock, power to the compressor sh
ould remain off during
performance of Steps 2 through 10.

Page 4
inlet. In addition, a bi-directional heat pump liquid line drier or factory recommended driers must be
installed. NOTE: ALWAYS REMOVE OLD FILTER DRIERS.
5.BRAZE ON SUCTION AND DISCHARGE LINES. Flow an inert gas, such as nitrogen or CO2, through the
system at approximately 2 psig. This will reduce the possibility of oxidation inside the tubing. Braze on the
suction and discharge lines and braze the process tube shut following the recommendation listed below (if
the process tube is to be used, it should be brazed shut after the system has been charged):
COPPER TUBING: If additional copper tubing is required, use only clean, dehydrated refrigeration
grade tubing with sealed ends.
BRAZING ALLOYS: CAUTION: Do not use 95/5, 50/50 or 40/60 soft solder for brazing.Use Sil-Fos or
Phos Copper, or similar brazing alloys with high tensile strength on copper
welds only. Weld steel to copper only with silver brazing alloys.
BRAZING PROCEDURE: To ensure properly brazed joints, Bristol Compressors recommends that the
following steps be used:
a. Exercise extreme care when cutting and forming tubes to keep dirt, filings,
and other contaminants from entering the system.
b. Do not use excessive amounts of brazing alloy as some of the excess may
penetrate the joint and enter the system.
c. If flux must be used, take necessary precautions to ensure that the flux does
not enter the system.
d. Use damp cloths or other heat absorbent material to ensure that the factory-
brazed joints on the compressor do not become damaged. If damp cloths
are used, take care not to allow moisture to enter the system.
e. Do not overheat brazed joints as excess heat will cause formation of copper
oxide on the inside wall of the tubing. Flow an inert gas through the system,
as explained above.
6. CHECK SYSTEM FOR LEAKS. After installation is complete, pressurize the system to 75 psig using
nitrogen and a few ounces of system refrigerant. Check for leaks using a halide torch, soap bubbles or an
electronic halogen leak detector. When all connections test satisfactorily, release pressure using proper
recovery procedures, then proceed to next step.
7. EVACUATE THE SYSTEM. Use a vacuum pump designed for this purpose. Vacuum must be pulled on
the discharge (high side) and suction (low side) of the system. Evacuate to 200 microns or lower.
8. CHECK THE ELECTRICAL SYSTEM. While the system is evacuating, connect the electrical leads to the
compressor terminals. Verify that the electrical system is wired according to the unit’s manufacturer and
Bristol’s wiring diagram on page 9. Verify that the electrical components match those specified on the
compressor electrical data sheet on pages 10 through 14. Start components (start capacitor and relay)
are required on all systems that incorporate a hard shut-off or non-bleed thermostatic expansion
valve. It is a normal practice to replace all starting components any time a compressor is changed. Check
all connections and terminals to be sure they are tight. Connect the crankcase heater (standard on all “A”
Series). Power to the crankcase heater must be energized continuously. Voltage to an insertion type
heater can be anything between 187 to 600 volts. Operational voltage for wrap-around type heaters must
be verified.
CAUTION: Do not use the Bristol replacement compressor as an evacuation assist and never
apply voltage to a compressor while it is in a vacuum as damage could result.
WARNING: Application of voltage to the compressor with the terminal cover and retainer removed
can result in serious personal injury or death.

Page 5
9. CHARGE THE SYSTEM. When a vacuum of at least 200 microns is reached, close gauge valve, remove
vacuum pump, and break the vacuum using system refrigerant vapor. Never dump liquid refrigerant into
the compressor. Liquid can be used to break the vacuum if it is connected to the liquid line, not the
discharge line.
Charge the system according to the manufacturer’s specifications. Be sure to compensate the charge for
the addition of the filter drier. Consult unit pressure/superheat chart on the unit door panel for the correct
superheat since pressures and superheat change with the ambient temperature.
WEIGHING in the system charge to the factory specification will help point out system faults that
may still exist.
10. START-UP. CLAMP-ON AMMETER MUST BE IN PLACE BEFORE POWER IS APPLIED TO MONITOR
START WINDING CURRENT ON START-UP!! See page 6
ASSURE THESE NORMAL START WINDING CURRENTS ON START-UP
CONFIGURATION APPROX. CURRENT
NORMAL START WITH RUN CAP ONLY 2 -10 AMPS
NORMAL START WITH RUN AND START CAP 20 AMPS AND DROP TO 2-10 AFTER START
NORMAL START WITH START CAP (INDUCTION RUN) 20 AMPS AND DROP TO 0 AFTER START
WARNING: If above currents are exceeded for more than 5 seconds, disconnect power and
correct the fault before restarting.
NOTE: Assure voltage to compressor does not drop below minimum allowable voltage (eg. 197
volts for 230/208-1-60) during the period the compressor is trying to start. Refer to page 2
for explanation of test to check LOCKED ROTOR PULL-DOWN VOLTAGE.

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).
STEP 3: Check suction superheat 6” from compressor inlet.
STEP 4: Superheat should not drop below 5°F (3°K) (prefer no lower than 10°F [6°K]).
STEP 5: Sump temperature should always be 50°F (28°C) or higher above saturated suction temperature.
EXAMPLE: “R-22”
38 psig = 16°F (-9°C) = SATURATED SUCTION
+ 50°F (28°K) = MINIMUM TEMP. DIFFERENCE
66°F (19°C) = MINIMUM SUMP TEMPERATURE
COOLING MODE (HEAT PUMP)
STEP 1: Operate system in cooling mode with indoor fan disconnected and repeat steps 3, 4 and 5.

12. CHECK FILTER DRIERS FOR CONTAMINATION.
A. 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.

Page 8
B. Liquid Line Filter: Always replace the original equipment liquid line filter drier(s). If the OEM liquid
line drier(s) is not removed from the system, a restriction most likely will result. A slight restriction in
this filter will reduce the efficiency of the system. A large restriction will cause the suction pressure
and discharge pressure to be reduced. This reduction in pressure will occur only with a properly
charged system (i.e., refrigerant weighed in to the OEM specifications). An over-charged system will
increase pressures when there is a restriction in the liquid line. The service person tends to add
more charge to the system to increase the suction pressure. Normally, any charge added above the
OEM specifications will increase the suction pressure due to the discharge pressure increasing but in
the case of a restriction, charge can be added to a point the system shuts down on the high pressure
limit switch. The service person may not see the higher discharge pressure due to his service port
being in the liquid line which is normally downstream from the liquid line filter drier in residential split
systems. A pressure port installed in the hot gas discharge line just as it exits the compressor is
required to see true discharge pressure.
C. Discharge Line Filter: Some OEM equipment may have a filter in the hot gas line (6” –12” from
compressor). Checks outlined in (B) above apply.
IMPORTANT: The compressor has an internal relief valve (IPRV) that is designed to open if the
system is subjected to a high pressure situation. Example causes are: overcharged, air in system,
restriction, factory-installed metering device screens not removed and cleaned, old liquid line filter left
in the system, poor airflow across the condenser, condenser fan failure, poor airflow across the
evaporator in the heating mode (dirty return air filter(s)), poor system design (duct system
undersized), etc. The IPRV will open when the discharge pressure exceeds the suction pressure by
more than 450 psi (“B” products) or 400 psi (“A” products). If the relief valve opens, a high velocity
gas flow may be heard inside the compressor housing. In some cases, the relief valve may open so
quickly due to a restriction in the system, the high pressure will be difficult to observe on standard
gauges. In most instances, if the service person installs a discharge service gauge on the discharge
line just as it exits the compressor, the development of high pressure can be observed before the
relief valve opens. Installing the discharge service gauge on the liquid line outside the system may
not detect a restriction. To reset the relief valve, shut the compressor off for at least 5 minutes,
allowing pressures to equalize.

PED LABEL INFORMATION
Explanation of the European Pressure Equipment Directive (PED) label information
(if the compressor is PED-approved):
•The first five digits of the 11-digit serial number give the manufacture and leak test date of the
compressor. The first three digits represent the day of the year (for example: 059 = February 28). The
next two digits represent the year (for example: 02 = 2002).
•PS is the maximum allowable pressure
•PT is the leak test pressure
•TS (max) is the maximum design temperature
•TS (min) is the minimum design temperature
