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: ir 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.
WARNING: R410 systems operate at 50% - 60% higher pressure than R22. R22
service equipment should not be used with R410 refrigerant. Refer to the attached
pressure temperature chart (see page 31 for comparison).
BEFORE CONDEMNING A SINGLE-PHASE COMPRESSOR THAT FAILS TO START…
1. Ve ify all following components a e OK:
. 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 (assu e comp esso 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. Ve ify locked oto pull-down voltage (LRPDV). lways 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:
Wa ning! Make su e system is p ope ly g ounded befo e p oceeding!
. 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 5.)
D. pply 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. Di ect wi ing. This wiring eliminates all other components and system wiring.
. Hard-wire from a fused disconnect to the C and R terminals of the compressor
B. Wire in a new run capacitor from the S terminal to the R terminal 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 11, 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 compres-
sor still does not start, it is definitely faulty.
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 CO
2
for this purpose, be sure to use a regulator
that can control the pressure down to 1 psig.

INSTALLATION PROCEDURES AFTER COMPRESSOR HAS BEEN VERIFIED AS 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.
VERY IMPORT NT
Do not leave compressor or system open to atmosphere for longer than 15 minutes maximu. The Polyolester lubricants are at
least 100 times more hygroscopic (ability to absorb moisture) than mineral oils. It is almost impossible to remove the moisture
absorbed by the lubricant even with heat and vacuum.
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 f equency characteristics are the same.
B. Verify if the new replacement compressor requires a discharge muffler. Do not emove the discha ge
muffle f om the system unless you replace it with the required muffler for the new compressor. See page
13 for muffler information. Consult your wholesaler if you have any questions about proper compressor ap-
plication.
WARNING: To avoid electrical shock, power to the compressor should remain off during performance
of Steps 2 through 10.
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.
. BEFORE REMOVING THE FAULTY COMPRESSOR: Remove refrigerant charge using proper recovery
procedures. Call 1-800-235-7882 for the name of the nearest Dupont authorized distributor, or
1-800-631-8138 for Honeywell Chemical Representative or 1-800-725-5532 Mexichem for information on re-
frigerant reclaim programs.
B. Remove the electrical leads from the compressor. Note and label the terminal to which each wire is con-
nected.
C. During the next operation, the access ports should be open so that pressure does not build up in the sys-
tem. Use a high temperature torch to sweat the suction line and the discharge line loose from the compres-
sor.
D. Remove the faulty compressor.
E. Assu e excessive oil does not emain in the system. Measu e oil in the failed comp esso and, if oil
is low, flush excess f om system (o see alte native below).
Good indicators of excess oil are: violent vibration and/or high va iable sound as the extra oil moves
through the system.
Alte natives: 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 in-
stalled)
- Recover refrigerant and remove the compressor
- Remove oil from the compressor and recharge with fresh oil per the manufacturer’s specifications

Page 4
CAUTION: The compressor may contain harmful acids—-be sure to handle with extreme care using
proper protection equipment. fter confirming oil charge level, return oil to compressor and install suc-
tion and discharge rotalock caps. Copper tube fittings should be brazed closed. This is needed to pre-
vent 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 connec-
tions have been completed (i.e., filters installed and all tubing changes made—-see steps 4, 5 and 6). gain, the
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 the proper discharge muffler if the system does not have one. Refer to Tables 3 and 4 on page 12 to con-
firm if the replacement compressor requires a discharge muffler and the size required. H22J and R92J com-
p esso s have an inte nal muffle , the efo e, the tables do not apply to these two models.
5. 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. Fo heat pumps, a suction
filte d ie must be installed between the accumulato and the comp esso suction inlet. In addition, a bi-
di ectional heat pump liquid line d ie o facto y ecommended d ie s must be installed. NOTE: AL-
WAYS REMOVE OLD FILTER DRIERS.
6. BRAZE ON SUCTION AND DISCHARGE LINES. Flow an inert gas, such as nitrogen or CO
2
, through the sys-
tem at approximately 1/4 to 1 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. Note:
The process tube has been eliminated on most compressors.
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 o 40/60 soft solde fo b azing. 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 pene-
trate 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 ex-
plained above.
7. CHECK SYSTEM FOR LEAKS. fter 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 proce-
dures, then proceed to next step.

Page 5
8. CAUTION: The compressor may contain harmful acids—-be sure to handle with extreme care using proper
protection equipment. fter confirming oil charge level, return oil to compressor and install suction and dis-
charge rotalock caps. Copper tube fittings should be brazed closed. This is needed to prevent further con-
tamination of the compressor and to prevent spillage from the compressor.
9. 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. Sta t components (sta t capacito and elay) a e equi ed on all sys-
tems that inco po ate a ha d shut-off o non-bleed the mostatic 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 “ ” Series). Powe to the c ankcase heate
must be ene gized continuously. Voltage to an insertion type heater can be anything between 187 to 600
volts. If supplied, the inse tion heate s a e identified by thei black o ed leads coming f om a well at the
bottom of the comp esso . Operational voltage for wrap-around type heaters must be verified.
WARNING: pplication of voltage to the compressor with the terminal cover and retainer removed can result
in serious personal injury or death.
10. CHARGE THE SYSTEM. When a vacuum of at least 200 microns is reached, close gauge valve, remove vac-
uum pump, and break the vacuum by charging the system through the liquid line—-not the discha ge line. To
assure the proper refrigerant composition is charged in the system with non azeotrope refrigerants, it is import
that liquid only be removed from the charging cylinder. Never dump liquid refrigerant into the compressor. Since
some compressors may be damaged if liquid refrigerant enters the suction side of the compressor, it is important
to charge the refrigerant slowly into the suction line to allow it to vaporize before it enters the compressor.
throttling valve can be used to ensure that the liquid is converted to vapor prior to entering the system.
Charge the system according to the manufacturer’s specifications. Be sure to compensate the charge for the ad-
dition 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 cha ge to the facto y specification will help point out system faults that may
still exist.
11. START-UP. CLAMP-ON AMMETER MUST BE IN PLACE BEFORE POWER IS APPLIED TO MONITOR
START WINDING CURRENT ON START-UP!! See page 6.
12. Most of today’s high efficiency compressors will actually start and run on the start winding if line voltage is ap-
plied to the start winding instead of the run winding (i.e., the start and run wire are reversed—-see schematic on
page 6). For this reason, the voltage must be checked on the common and run terminal of the compressor to
confirm the line voltage is being applied to the proper terminals. If the voltage on the common and run terminals
is higher than the line voltage supplied to the system—check system for proper wiring.

HEAT PUMP
STEP 1: Operate system in the heating mode with outdoor fan disconnected.
STEP : 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 ( 8°C) or higher above saturated suction temperature.
EXAMPLE: “R-22”

14. CHECK FILTER DRIERS FOR CONTAMINATION.
. Suction Line Filte : 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.
B. Liquid Line Filte : lways 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. slight restriction in
this filter will reduce the efficiency of the system. 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). n 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 sys-
tems. pressure port installed in the hot gas discharge line just as it exits the compressor is required
to see true discharge pressure.
C. Discha ge Line Filte : 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 sys-
tem is subjected to a high pressure situation. Example causes are: overcharged, air in system, re-
striction, 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 evapora-
tor 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 psig
(“B” and “J” products) or 400 psig (“ ” products) with R-22 refrigerant and increases to 550 psig for all
R410 products. If the relief valve opens, a high velocity gas flow may be heard inside the compres-
sor housing. In some cases, the relief valve may open quickly due to a restriction in the system. If this
occurs, the high pressure may be difficult to observe on standard gauges. In these instances, installa-
tion of a discharge service gauge on the discharge line just as it exits the compressor, the develop-
ment 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.

Sta t Component Elimination
n innovative starting concept has been developed by Bristol Compressors that eliminates the compressor start com-
ponents (start capacitor/relay) required for systems using non-bleed type expansion valves. This optional feature is
available on select “BENCHM RK” models. They are identified by the letter “B” in the seventh cha acte of the
model number (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.
It is recommended that each OEM perform start tests at their worst case condition to assure no issues with their
placement of the check valve. It is also important to determine if the equalization time is acceptable with the check
valve moved downstream of the compressor discharge connector. This technique will help maintain system operating
pressures during the off-cycle, thus improving the SEER performance by decreasing C
D
. The internal equalization is
transparent to the customer and requires no special attention.
Bleed Comp esso s with Oval Housing
Only an external check valve is required since these models employ an inte nal discha ge muffle . (Exception: 50
Hz ope ation equi es exte nal muffle ). gain, the check valve may be installed at any point in the hot gas line, pref-
erably as close to the compressor discharge connector as possible. See Table 2 for recommended check valves. Refer
to Table 3, page 12, for external muffler requirements for 50 Hz operation only.
Sta ting Cha acte istics
The “BENCHM RK” H2*J models do not require start components on systems where the pressure equalizes
completely in the off-cycle. For single-phase applications, a low torque PTCR can be used if only a light assist is
needed, as in the case of a low voltage condition. If a non-bleed expansion valve is used, or other reasons exist
that will not allow pressure equalization prior to compressor start-up, then a start capacitor and potential relay are
required. (Exception: See Start Component Eliminations below for an option to eliminate starting components.)
High torque start components are available for the “BENCHM RK” model. The PTCR and starting components
are listed under the Electrical ccessory Components section of the individual compressor specification sheet.

pressors.

Bleed Comp esso s with Round Housing
These models do not employ an internal discharge muffler; therefore they require one of the following options:
1) An exte nal discha ge muffle with integ al check valve. See External Discharge Muffler Require-
ment—Round Housing. See Table 4 for a listing of these mufflers with integral check valves which inte-
grate the individual components into one compact assembly thus reducing the number of braze joints.
Properly installed, this method is effective for reliable starting without a start capacitor/relay at all ex-
pected differentials. 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.
2) A check valve installed as close to the compressor discharge connector as possible, along with a
sepa ate discha ge muffle installed downstream (see Table 3 for muffler; must be installed as illus-
trated in Section 9).
System designe s must pe fo m system evaluations to assu e the p essu es a e equalized ac oss the
comp esso befo e each comp esso sta t-up and to set thei time delay acco dingly.

Exte nal Discha ge Muffle Requi ement - Round Housing
NOTE: 60 Hz oval housing models do not equi e an exte nal discha ge
muffle .
NOTE: Use of only an exte nal discha ge muffle (i.e., no check valve) ap-
plies only to models that do not have a “B” in the seventh cha ac-
te of the model numbe .
Bristol Compressors’ research has proven that the use of an external discharge
muffler is far superior to the internal style. This is due to the space limitation
and “fixed” location within the hermetic shell. The external muffler approach
gives the system designer the opportunity to utilize the most effective muffler
type and location. The ound housing “BENCHM RK” models do not employ
an internal discharge muffler and require that an external muffler be precisely
placed in the discharge line as illustrated in Figure 1. For 60 Hz applications,
install assembly with 13 inches (±2 in.) or 33 cm (±5.1 cm) of tubing between
the discharge tube outlet and the muffler. For 50 Hz applications, install as-
sembly with 20 inches (±2 inches) or 50.8 cm (±5 cm) of tubing between the
discharge tube outlet and the muffler (refer to dimension “ ” in Figure 1 of tub-
ing placement). The muffler must be UL/CS certified for use as a high-side
component for the intended refrigerant application.
IMPORTANT NOTES:
1) It is preferable that the muffler be installed as shown in Figure 1 with use
of the mufflers shown in Table 3. However, if it is necessa y that bends
be placed in the tube between the comp esso and the muffle , both
indoo and outdoo sound evaluations must be pe fo med to confi m
acceptance of the final configu ation. B istol field testing indicates
any bends p io to the muffle can esult in inc eased sound and tub-
ing vib ation, p ima ily with coppe muffle s.
2) If the Sporlan muffler Part No. M-16E32 (see Table 3) is used, the DIM “ ” tube may be reduced to a minimum length
of 9 inches. No bends would be allowed in the tube between the compressor and the muffler.
3) The tubing design between the compressor and the condensing unit coil is very important in regard to both sound per-
formance and reliability. The length, number of bends, geometry, and method of attachment can have a significant im-
pact on acoustic performance of the muffler and tube vibration levels. The system tubing vib ation should be tho -
oughly evaluated using accele omete s. Discharge tube total displacement (peak-to-peak) needs to be kept below
0.011 inches (as measured 3.5 inches from the top of the compressor discharge elbow) to avoid premature tubing fail-
ure due to excessive vibration.
The Table 3 gene ic muffle ecommendations a e based on B istol sound test evaluations with va ious sys-
tems. The Spo lan M-16E32 yielded the best ove all field esults. Operational characteristics can vary between
different system types and applications. The OEM system designer must perform sound tests to determine the best
muffler configuration and optimize its location in the discharge line to satisfy their particular design requirements. ll
available options should be thoroughly evaluated and the following considered:
• A heat sink is equi ed to p event inte nal check valve damage du ing b azing
• Do not use ball type check valve
• filter-drier in the discharge line may be substituted for the external muffler, if system testing confirms that the
filter-drier provides acceptable discharge pulse and sound attenuation.
• If components othe than those ecommended in Tables 2, 3 and 4 a e 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/CS certified for use as high side components for the intended refrigerant application.
• Increased internal free volume or multi-chamber style discharge mufflers may provide superior results.
If your have a compressor that is not listed on pages 14 through 30, contact your Wholesaler or Distributor for installation
procedures and electrical components.
