COMPONENT OPERATION AND TESTING  
WARNING  
Testing Procedures  
1. Terminal "C" and "S" – no continuity – open winding  
– replace compressor.  
DISCONNECT ELECTRICAL POWER TO THE  
UNIT BEFORE SERVICING OR TESTING  
2. Terminal "C" and "R" – no continuity – open winding  
– replace compressor.  
3. Terminal "R" and "S" – no continuity – open winding  
- replace compressor.  
COMPRESSORS  
Compressors are single phase, 208/230 volt. All compressor  
motors are permanent split capacitor type, using only a running  
capacitor across the start and run terminal.  
4. Terminal "C" and the shell of the compressor – continuity  
– grounded motor – replace compressor.  
5. Should continuity exist between terminals "R" and "S",  
but not between terminals "C" and "S" and "C" and "R",  
the internal overload may be open. If the compressor is  
extremely hot, allow it sufcient time to cool. It may require  
as long as one hour for the compressor to cool sufciently  
for the internal overload to close.  
All compressors are internally spring mounted and externally  
mounted on rubber isolators.  
Line Voltage Overload  
The compressor is equipped with an internal line voltage over-  
load. This overload is embedded in the windings of the motor  
to sense the motor temperature. The overload will open and  
disconnect the power to the motor due to high temperatures  
caused by:  
GROUND TEST  
Use an ohmmeter set on its highest scale. Touch one lead to  
thecompressorbody(cleanpointofcontact, asagoodconnec-  
tion is a must) and the other probe in turn to each compressor  
terminal. (See Figure 3.) If a reading is obtained, the compressor  
is grounded and must be replaced.  
1. A locked rotor.  
2. Excessive running amps.  
3. High discharge temperature.  
4. Low refrigerant charge.

OHMMETER  
CHECKING COMPRESSOR EFFICIENCY  
The reason for compressor inefciency is normally due to bro-  
ken or damaged suction and/or discharge valves, reducing the  
ability of the compressor to pump refrigerant gas.  
COMPRESSOR WINDING TEST (Figure 2.)  
Remove the compressor terminal box cover and disconnect the  
wires from the terminals. Using an ohmmeter, check continuity  
across the following:  
This condition can be checked as follows:  
1. Install a piercing valve on the suction and discharge or liquid  
process tube.  
FIGURE 2 COMPRESSOR WINDING TEST  
2. Attach gages to the high and low sides of the system.  
3. Start the system. Run a "cooling or heating performance test."  
If test shows:  
A. Below normal high side pressure.  
B. Above normal low side pressure.  
C. Low temperature difference across the coil.  
The compressor valves are faulty - replace the compressor.

FAN MOTOR (Figure 4)  
CAPACITOR, RUN  
A 230 volt single phase permanent split capacitor motor is  
used to drive the evaporator blower and condenser fan. A  
running capacitor is wired across the start and run terminals  
of the motor.  
A run capacitor is wired across the auxiliary and main winding  
of a single phase permanent split capacitor motor such as the  
compressor and fan motors. A single capacitor can be used for  
each motor or a dual rated capacitor can be used for both.  
The motor is totally enclosed and is protected with a line volt-  
age overload located internally of the motor. The motor shaft  
is stainless steel to resist corrosion.  
The capacitor’s primary function is to reduce the line current  
while greatly improving the torque characteristics of a motor.  
The capacitor also reduces the line current to the motor by  
improving the power factor of the load. The line side of the  
capacitor is marked with a red dot and is wired to the line side  
of the circuit (see Figure 7.)

3. For dual rated capacitors, apply an ohmmeter lead to  
the common (C) terminal and the other probe to the  
compressor (HERM) terminal. A satisfactory capacitor will  
cause a deection on the pointer, then gradually move back  
to innity.  
Load side  
4. Reverse the leads of the probe and momentarily touch the  
capacitor terminals. The deection of the pointer should be  
two times that of the rst check if the capacitor is good.

5. Repeat steps 3 and 4 to check the fan motor capacitor.  
SYSTEM CONTROL SWITCH (Figure 6)  
This switch is double pole, single throw. Check for continuity  
between terminals 2 and 3, and 5 and 6.  
NOTE: A shorted capacitor will indicate a low  
resistance and the pointer will move more to the “0”  
end of the scale and remain there as long as the  
probes are connected. An open capacitor will show  
no movement of the pointer when placed across the  
terminals of the capacitor.

LOW AMBIENT  
Bypass VALVE  
A cross ambient thermostat is used to maintain the desired  
comfort level. The thermostat reacts only to a change in  
temperature at the bulb location. Important to the successful  
operation of the unit is the position of the sensing bulb in relation  
to the evaporator (see Figure 8).

a. Balance Scales - 1/2 oz. accuracy  
b. Charging Board - 1/2 oz. accuracy  
LOW AMBIENT BYPASS VALVE (Figure 9)  
The HazardGard unit is designed to operate at low outside  
ambient temperatures. This is accomplished by the use of a  
bypass valve installed in the refrigeration circuit. The valve  
is connected between the discharge line at the compressor  
and the suction process tube. The valve responds to suction  
pressure which, when reduced in the system, causes the  
valve to open and bypass hot gas from the high pressure side  
to the low pressure side of the system. The hot gas entering  
the compressor mixes with the cool gas returned through the  
suction line, thus increasing the suction pressure. The valve  
is preset to open when the suction pressure reaches 50 psig.  
This pressure setting cannot be altered. The system can be  
operated at outdoor temperatures as low as 45° F before the  
evaporator coil will begin to accumulate frost.  
9. High Pressure Gauge - (0-400 lbs.)  
10. Low Pressure Gauge - (30" - 150 lbs.)  
11. Vacuum Gauge - (0-1000 microns)  
Equipment Must Be Capable of:  
1. Recovering CFC’s as low as 5%.  
2. Evacuation from both the high side and low side of the  
system simultaneously.  
3. Introducing refrigerant charge into the high side of the  
system.  
To determine if the valve operates, block the return air to the  
evaporator coil. Turn on the unit and touch the tube at the  
bypass valve outlet which connects to the suction process  
tube. When the low side pressure reaches approximately 50  
psig, the valve will begin to open and the tube will get hot. This  
method will determine if the valve is responding to the suction  
pressure change.  
4. Accurately weighing the refrigerant charge actually intro-  
duced into the system.  
5. Facilities for owing nitrogen through the refrigeration  
tubing during all brazing processes.

12. Restart the unit several times after allowing pressures  
to stabilize. Pinch off the process tubes, cut and solder  
the ends. Remove the pinch off tool, and leak check the  
process tube ends.  
HERMETIC COMPONENT REPLACEMENT  
The following procedure applies when replacing components  
in the sealed refrigeration circuit or repairing refrigerant leaks.  
(Compressor, condenser, evaporator, capillary tube, refrigerant  
leaks, etc.)  
SPECIAL PROCEDURES IN THE CASE OF  
COMPRESSOR MOTOR BURNOUT  
1. Recover the refrigerant from the system at the process  
tube located on the high side of the system by installing  
a line tap on the process tube. Apply the gauge from the  
process tube to EPA approved gauges from the process  
tube to the EPA approved recovery system. Recover the  
CFC’s in the system to at least 5%.  
1. Recover all refrigerant and oil from the system.  
2. Remove the compressor, capillary tube and lter drier from  
the system.  
3. Flush the evaporator, condenser and all connecting tubing  
with dry nitrogen, or equivalent, to remove all contamination  
from the system. Inspect the suction and discharge lines  
for carbon deposits. Remove and clean if necessary.  
2. Cut the process tube below the pinch off in the suction side  
of the compressor.  
3. Connect the line from the nitrogen tank to the suction  
process tube.  
4. Reassemble the system, including a new drier-strainer and  
capillary tube.  
4. Drift dry nitrogen through the system and unsolder the  
more distant connection first. (Filter drier, high side  
process tube, etc.)  
5. Proceed with processing as outlined under hermetic  
component replacement.  
5. Replace the inoperative component, and always install a  
new lter drier. Drift dry nitrogen through the system when  
making these connections.  
ROTARY COMPRESSOR  
SPECIAL TROUBLESHOOTING & SERVICE  
6. Pressurize the system to 30 PSIG with proper refrigerant  
and boost the refrigerant pressure to 150 PSIG with dry  
nitrogen.  
Basically, troubleshooting and servicing rotary compressors  
is the same as on the reciprocating compressor with only a  
few exceptions.  
7. Leak test the complete system with the electric halogen  
leak detector, correcting any leaks found.  
1. Because of the spinning motion of the rotary, the mounts  
are critical. If vibration is present, check the mounts  
carefully.  
8. Reduce the system to zero gauge pressure.  
2. The electrical terminals on the rotary are in a different order  
than the reciprocating compressors. The terminal markings  
are on the cover gasket. Use your wiring diagram to insure  
the correct connections.  
9. Connect the vacuum pump to the high side and low side  
of the system with deep vacuum hoses, or copper tubing.  
(Do not use regular hoses.)  
10. Evacuate the system to an absolute holding pressure of  
200 microns or less.  
REFRIGERANT CHARGE  
1. The refrigerant charge is extremely critical. Measure the  
charge carefully and as exactly as possible to the nameplate  
charge.  
NOTE: This procedure can be sped up by the use of  
heat lamps, or by breaking the vacuum with refrigerant  
or dry nitrogen at 5,000 microns. Pressure system to 5  
PSIG and leave in the system a minimum of 10 minutes.  
Recover refrigerant, and proceed with evacuation to a  
pressure of 200 microns or a minimum of 10%.  
2. The correct method for charging the rotary is to introduce  
liquid refrigerant into the high side of the system with the  
unit off. Then start the compressor and enter the balance  
of the charge, gas only, into the low side.  
The introduction of liquid into the low side, without the use of  
a capillary tube, will cause damage to the discharge valve  
of the rotary compressor.  
11. Break the vacuum by charging the system from the high  
side with the correct amount of refrigerant specied. This  
will prevent boiling the oil out of the crankcase.  
NOTE: All inoperative compressors returned to Friedrich  
must have all lines properly plugged with the plugs from  
the replacement compressor.  
NOTE: If the entire charge will not enter the high side,  
allow the remainder to enter the low side in small  
increments while operating the unit.
