COMPONENT OPERATION AND TESTING
WARNING
FIGURE 2 TYPICAL GROUND TEST
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 sufficient time
to cool. It may require as long as one
hour for the compressor to cool
sufficiently for the internal overload to
close.
COMPRESSOR WINDING TEST
(See Figure 1.)
Remove the compressor terminal box cover
and disconnect the wires from the terminals.
Using an ohmmeter, check continuity across
the following:
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.
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.

OHMMETER
SYSTEM CONTROL SWITCH
(Figure 5)
This switch is double pole, single throw. Check
for continuity between terminals 2 and 3, and 5
and 6.
FAN MOTOR
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.
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.
CHECKING COMPRESSOR EFFICIENCY
The reason for compressor inefficiency 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.
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.
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 2.) If a
reading is obtained, the compressor is
grounded and must be replaced.

FIGURE 6 RUN CAPACITOR HOOK–UP
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 6.)
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 7.

(Part No. 618-225-02)
60°F ( ± 2°) to 90°F( ± 4°)
FIGURE 7 SENSING
BULB LOCATION
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
deflection on the pointer, then gradually move
back to infinity.
4. Reverse the leads of the probe and
momentarily touch the capacitor terminals. The
deflection of the pointer should be two times
that of the first check if the capacitor is good.
5. Repeat steps 3 and 4 to check the fan
motor capacitor.
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.

TRIAC
With the system switch in the "On" position
and the thermostat closed, current flows
through the control components of the
printed circuit board to the TRIAC causing it
to switch on, starting the compressor. If the
compressor fails to start and the compressor
has been tested by the direct start method,
and the thermostat tests satisfactorily,
replace both the TRIAC and the printed
circuit control.
The TRIAC is located on
the evaporator header inside the control
panel.
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.
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.

LOW AMBIENT BY–PASS VALVE
The HazardGard unit is designed to operate at
low outside ambient temperatures. This is
accomplished by the use of a by–pass 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 by–pass 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.
To determine if the valve operates, block the
return air to the evaporator coil. Turn on the
unit and touch the tube at the by–pass 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.

10.Evacuate the system to an absolute holding
pressure of 200 microns or less.
NOTE: This procedure can be speeded 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 specified. 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 BURN-OUT
1. Recover all refrigerant and oil from the
system.
2. Remove the compressor, capillary tube and
filter 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.
4. Reassemble the system, including a new
drier-strainer and capillary tube.
5. Proceed with processing as outlined under
hermetic component replacement.
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 first.
(Filter drier, high side process tube, etc.)
5. Replace the inoperative component, and
always install a new filter 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.
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
NOTE:
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.
ROTARY COMPRESSOR SPECIAL
TROUBLESHOOTING AND SERVICE
Basically, troubleshooting and servicing
rotary compressors is the same as on the
reciprocating compressor 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.
