COMPONENT OPERATION AND TESTING
WARNING
DISCONNECT ELECTRICAL POWER TO THE
UNIT BEFORE SERVICING OR TESTING
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.
FIGURE 2 COMPRESSOR WINDING TEST
All compressors are internally spring mounted and
externally mounted on rubber isolators.
Line Voltage Overload
The compressor is equipped with an internal line
voltage overload. 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:
1. A locked rotor.
2. Excessive running amps.
3. High discharge temperature.
4. Low refrigerant charge.
FIGURE 1 INTERNAL OVERLOAD
LINE BREAK
INTERNAL OVERLOAD
OHMMETER
Testing Procedures
1. Terminal "C" and "S" - no continuity - open
winding - replace compressor.
2. Terminal "C" and "R" - no continuity - open
winding - replace compressor.
3. Terminal "R" and "S" - no continuity open
winding - replace compressor.
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 suffi cient time to
cool. It may require as long as one hour for
the compressor to cool suffi ciently for the
internal overload to close.
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:
4
GROUND TEST
Use an ohmmeter set on its highest scale. Touch one
lead to the compressor body (clean point of contact,
as a good connection 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.
FIGURE 3 TYPICAL GROUND TEST
CHECKING COMPRESSOR EFFICIENCY
The reason for compressor ineffi ciency is normally
due to broken or damaged suction and/or discharge
valves, reducing the ability of the compressor to pump
refrigerant gas.
This condition can be checked as
follows:
1. Install a piercing valve on the suction and
discharge or liquid process tube.
2. Attach gages to the high and low sides of
the system.
FAN MOTOR (Figure 4)
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.
The motor is totally enclosed and is protected with a line
voltage overload located internally of the motor. The
motor shaft is stainless steel to resist corrosion.
FIGURE 4 FAN MOTOR
FAN MOTOR – TEST
Disconnect power to the unit.
1. Determine that the capacitor is serviceable.
2. Disconnect the black lead from the circuit
board.
3. Apply "live" test cord leads to the common
terminal of the capacitor and the black lead.
The motor should run at high speed.
SOLID STATE RELAY (Figure 5)
Two 50 amp rated 208/230 volt solid state relays
are used to energize the compressor and fan motor.
Terminals 3 and 4 are the 208/230 volt line side.
Terminals 1 and 2 are load side contacts.
3. Start the system and 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.

SYSTEM CONTROL SWITCH (Figure 6)
This switch is double pole, single throw. Check for
continuity between terminals 2 and 3, and 5 and 6.
FIGURE 6 SWITCH, ON-OFF
CAPACITOR – TEST
1. Remove the capacitor from the unit.
2. Check for visual damage such as bulges, cracks,
or leaks.
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 defl ection on the pointer,
then gradually move back to infi nity.
4. Reverse the leads of the probe and momentarily
touch the capacitor terminals. The defl ection of the
pointer should be two times that of the fi rst check
if the capacitor is good.
5. Repeat steps 3 and 4 to check the fan motor
capacitor.
CAPACITOR, RUN
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 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.)
FIGURE 7 RUN CAPACITOR HOOK–UP
COMPRESSOR

MOTOR
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.
THERMOSTAT
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).

TEST
Remove the wires from the thermostat. Turn the
thermostat to its coldest position. Check to see if
there is continuity between the two terminals. Turn the
thermostat to its warmest position. Check continuity
to see if the thermostat contacts open.
Note: The temperature must be within the range listed
to check the thermostat. Refer to the troubleshooting
section in this manual for additional information on
thermostat testing.

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°
coil will begin to accumulate frost.
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.

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.)
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%.
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. Drift dry nitrogen through the system and unsolder
the more distant connection fi rst. (Filter drier, high
side process tube, etc.)
5. Replace the inoperative component, and always
install a new fi lter drier. Drift dry nitrogen through
the system when making these connections.
6. Pressurize the system to 30 PSIG with proper
refrigerant and boost the refrigerant pressure to
150 PSIG with dry nitrogen.
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%.
11. Break the vacuum by charging the system from
the high side with the correct amount of refrigerant
specifi ed. This will prevent boiling the oil out of the
crankcase.
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.
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.
SPECIAL PROCEDURES IN THE CASE OF
COMPRESSOR MOTOR BURNOUT
1. Recover all refrigerant and oil from the system.
7. Leak test the complete system with the electric
halogen leak detector, correcting any leaks
found.
8. Reduce the system to zero gauge pressure.
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.
2. Remove the compressor, capillary tube and fi lter
drier from the system.
3. Flush the evaporator, condenser and all connecting
tubing with dr y nitro gen, or e quivalent , to remove al l
contamination from the system. Inspect the suction
and discharge lines for carbon deposits. Remove
and clean if necessary.
4. Reassemble the system, including a new drierstrainer and capillary tube.
5. Proceed with processing as outlined under hermetic
component replacement.

ROTARY COMPRESSOR SPECIAL
TROUBLESHOOTING AND SERVICE
Basically, troubleshooting and servicing rotary compressors is the same as on the recip rocat ing co mpres sor with only a few exceptions.
1. Because of the spinning motion of the rotary, the
mounts are critical. If vibration is present, check
the mounts carefully.
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.
All inoperative compressors returned to Friedrich
must have all lines properly plugged with the
plugs from the replacement compressor.
REFRIGERANT CHARGE
1. The refrigerant charge is extremely critical. Measure
the charge carefully and as exactly as possible to
the nameplate charge.
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.
