COMPONENT OPERATION AND TESTING

WARNING

DISCONNECT ELECTRICAL POWER TO THE

UNIT BEFORE SERVICING OR TESTING

COMPRESSORS

Compressors are single phase, 208/23 0 volt. All c ompres sor motors are permanent split capacitor type, using only a running capacitor across the start and run terminal.

All compressor s are internally spr ing mounted and exter nally 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 cause d b y :

1. A locked rotor.

2. Excessive running amps.

3. High discharge temperature.

4. Low refrigerant charge.

Testing Procedures

1. Ter minal "C" and "S" – no continuity – open w inding – replace compressor.

2. Ter minal "C" and "R" – no continuit y – open winding – replace compressor.

3. Terminal "R" and " S" – no continuity – open winding

- replace compressor.

4. T erminal "C" and the shell of the compressor – continuity – grounded motor – replace compressor.

5. Should continuity exist bet ween 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.

GROUND TEST

Use an ohmmeter set on its highest scale. Touch one lead to the co mpresso r body ( cle an poin t of co ntact, 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.

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:

FIGURE 2 COMPRESSOR WINDING TEST

CHECKING COMPRESSOR EFFICIENCY

The reason for compressor inefﬁ ciency is normally due to bro-

ken 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. Run a "cooling or heating performance test."

If test sh ows:

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)

A 230 volt single phase permanent split capacitor motor is

used to drive the evaporator blower and condenser fan. A running capacitor is wired acros s the star t and r un terminals of the motor.

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 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.

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 20 8/230 volt solid state relays are used to

energize the compressor and fan motor. T erminals 3 and 4 are the 208/230 volt line side. Terminals 1 and 2 are load side contacts.

The capacitor’s primary function is to reduc e the line current

while greatly improving the torque characteristic s of a motor.

The capacitor also reduces t he 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.)

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

3. For dual rated capacitor s, 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 sh ould 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.

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 t he desired

comfort level. The thermost at reacts only to a change in temperature at the bulb location. Import ant to the succe ssful operation of the unit is the position of the sensing bulb in relation to the evaporator (see F igure 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 warme st posit ion. Check continuity to see if the thermostat contacts open.

Note: The temperature must be with in the range listed to check the thermostat. Refer to the troubleshooting sec tion 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 c ompressor and the suction process tube. The valve responds to suction pressure which, when reduced in the system, c auses 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 su ction pressure rea ches 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 i f the valve operates, block the return air to the

evaporator coil. Turn on the unit and touch t he 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 comp onents

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 %.

12. Rest art the unit several times after allowing pressures to stabilize. Pinch off the process tube s, 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.

2. Remove the compressor, capillary tube and ﬁ lter drier from the system .

2. Cut the process tube below the pinch off in the suction side of the compressor.

3. C onnect the line from the nitrogen tank to the suction process tube.

4. Drift dr y 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 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 dr y 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 sys t em wi th d eep v acu u m h oses , o r coppe r t ub ing .

(Do not use regular hoses.)

3. Flush the evaporator , condenser and all connecting tubing with dry nitrogen, or equivalent, to remov e 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. Proc eed with processing as outlined under hermetic component replacement.

ROTARY COMPRESSOR SPECIAL TROUBLESHOOTING & SERVICE

Basically, troubleshooting and servicing rotary compres sors is the same as on the reciprocating compressor w ith 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 corr e ct con n ec ti on s .

10. Evacuate the system to an absolute holding pressure of 200 microns or less.

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.

REFRIGERANT CHARGE

1. The refr igerant 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, in to 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.

NOTE: All inoperative compressors returned to Friedrich must have all lines properly plugged with the plugs from the replacement compressor.
