2.0 Safety Information
Refrigerant HFC-134a
All self-contained models covered in this service
manual are manufactured using refrigerant HFC134a.
Potential Problems with HFC-134a
HFC-134a compressors are manufactured with a
synthetic based ester oil charge.
• The hygroscopic (water attraction) property of
ester oil is many times greater than that of the
mineral oils previously used with CFC-12.
• High system moisture causes the formation
of acids and alcohol, which can damage the
compressor.
• Systems or components of the refrigeration
system should not be left open to atmosphere
for more than (15) minutes at any time as
humidity from the air will enter the system and
be absorbed by the oil.
To ensure system dehydration:
• System should be evacuated to a level less than
250 microns
• Flux must not be used on any brazed joints.
Anytime a Perlick Refrigeration System is being
serviced:
• It is recommended that the drier be changed
using the exact same style and size within the
system to avoid possible charge problems or
contaminant issues.
Service Manual Safety Labels
PLEASE READ all instructions completely before attempting to service the unit. Take particular note of
the DANGER, WARNING and CAUTION information
in this manual. The information is important for the
safe and efcient service, operation and care of the
Perlick unit.
HAZARD!!
Indicates hazardous situation that will result
in death or serious injury if not avoided.
• When isolated, shall not exceed 500 microns for
a minimum of 10 minutes.
• Vacuum pump oil must never be allowed to
enter the refrigeration system.
• No leak detection dyes are authorized for use
within any Perlick Refrigeration Products.
• Use of these materials will void complete sys
tem warranty and place the burden on the
service company for down-line service issues.
Cleanliness of the system is extremely important.
• The presence of residue (Chlorinated or greasy
residues, mineral oil, or impurities) can lead
to capillary tube restrictions, oil return prob
lems and compressor damage.
• A nitrogen purge should be utilized when
brazing.
Indicates hazardous situation that may
result in death or serious injury if not
avoided.
-
Caution indicates hazardous situation that
could result in minor or moderate injury and
property damage.
Caution without symbol indicates unsafe practice
situation that could result in property damage only.

4.0 Variable Speed Compressor Specication
Never connect compressor directly to AC power!
Always use specied inverter when testing
compressor!
• The compressors employed within many of Perlick’s cabinets are on the cutting edge of technology for
reciprocating hermetic compressors. The compressors are variable speed models developed and man
ufactured by Embraco. Depending on the model of the cabinet, either a VEMY3H, VEMY6H or VEGY7H
will be found powering the refrigeration system. The compressor itself looks like a standard fractional
horsepower hermetic reciprocating compressor. The electrical, overload, relay and capacitor, which
are normally found connected to the compressor pins has been replaced by an electronic box which is
called the inverter.
-
• The inverter is an electronic board, which controls the compressor and has to have power to it at all
times for it to function properly. It controls the starting of the compressor and the speed at which it is
running at from 1600 rpm to 4500 rpm. A normal hermetic reciprocating compressor runs at a con
stant 3600 rpm. The Digital Temperature Control controls a separate power circuit used as the power
to the inverter driver circuit, which turns the compressor on and off.
• The inverter is powered by 115-127V 50-60Hz 1 Ph AC. The inverter driver circuit power is also 115-
127V 50-60Hz 1Ph AC power. The inverter converts this to 230V 53-150Hz 3 Ph power to drive the
compressor. The resistance between any combination of the three compressor pins for the HP24”
Series is 16.07 ohms, and the HP48 & HP72” series is 6.4 ohms. The inverter has a plastic 3-pin recep
tacle which gets plugged onto the compressor pins (can only be installed one way for proper orientation). The inverter also comes with a ground wire, which gets plugged onto the compressor ground
lug. The inverter is then mounted to the compressor fence by sliding it down and tipping to the vertical
position. A single fastener is then used to mount it to the fence (do not over tighten as it is fastening
into the plastic inverter housing).

5.0 Compressor Inverter Operation
• Upon initial power to the inverter, the electronic board is checked for problems or malfunctioning
components. If a problem is detected, the inverter will not allow power to the compressor and will
wait 8 minutes until it will repeat the process to see if it has been corrected.
• If the inverter power circuit is interrupted or reduced to a level below operation level, the inverter will
not allow continued operation of the power circuit to the compressor.
Compressor Start-Up
• Upon the temperature control calling for cooling, the inverter will wait 1-3 seconds before applying
current to the compressor motor for the rst time. In case of any abnormality in trying to start the
compressor (unequal pressures, locked rotor condition or open winding, etc.), the inverter will wait
6 seconds before establishing a new start-up trial.
• The maximum number of start-up trials is 12. If the compressor does not start after 12 trials, a
start-up error is set, and the system will wait for 8 minutes to repeat the starting procedure.
• During start-up of the compressor, the current is limited in accordance with the type of motor
connected to the inverter. The compressor always starts in its minimum rpm condition (1600 rpm)
to conserve energy and alleviate noise associated with a standard compressor start-up.
• During initial power being applied to the refrigerated cabinet, the compressor will always start in its
minimum rpm condition (1600 rpm) and remain at this speed for 7 minutes. After this time has
passed the program will move the compressor to its maximum rpm level until the initial controller
cut-out temperature has been achieved.
Normal Operation
During running condition, the speed is measured each shaft turn and the result is compared with
the desired speed. If the actual speed is lower than desired, the inverter will increase the power applied
to the motor, which in turn will increase the shaft speed until the equilibrium is achieved. The opposite can
happen likewise, in that if the actual speed is higher than the desired speed, the inverter will decrease the
power applied to the motor, which in turn will decrease the shaft speed until the equilibrium is achieved.
The compressor will generally run at its slowest speed (1600 rpm) during normal cycling conditions with
out added load to the cabinet or door openings. This is done to conserve energy and reduce noise. A typical refrigeration system is designed for high load, high ambient conditions, meaning the compressor is
typically oversized for normal daily operation. It has been shown in residential equipment that a refriger
ator or freezer or combination of the two with standard reciprocating compressor is typically designed for
conditions it sees less than 25% of the time (high load/high ambient). While employing the variable speed
compressor the equipment has been designed for the conditions it sees 75% of the time while still having
the capacity to cover the conditions it sees 25% of the time.

6.0 Troubleshooting Compressor Inverter
• Ensure the inverter has 120V applied to the two pin connector on the inverter. If no power,
check where power is interrupted.
• If temperature control is calling for cooling, check inverter signal circuit for 120V, typically
the red lead. If no power, check where power is interrupted. If there is power, disconnect
power to the entire unit and wait 5 minutes to ensure internal system pressures are
equalized. Plug in unit and feel top of compressor to see if it is trying to start (see in-
formation from section Compressor Start-Up above). If compressor is trying to start, but
unable to, the system could have a restriction, the inverter may not be applying the correct
power to the compressor pins (check pins to see if getting 120V to each pin).
• Resistance between all pins should be the same. Dependent upon temperature of the com-
pressor, resistance could be different than the resistance specied at the standard temperature.

Air Inltration
Air inltration can occur in several locations.
Note: Unit may manifest longer than normal run
times caused by the additional loads that
air inltration presents.
Signs of air inltration include:
• Presence of water, moisture or ice
• Condensation on glass or metal surfaces
STEP 1. Door Gaskets
• Check door gaskets for rips, cracks, or oth
er damage.
• The door gasket should be pushed in rmly
and lay at.
• Ensure gasket forms a complete seal
around door.
-
STEP 2. Sealing Compound
• Sealing compound is used to seal wiring and
line set pass-through between the con
denser and the evaporator compartments.
See Figure 7-1 and Figure 7-2.
• Check for voids and ensure sealing
compound completely lls the space.

STEP 3. Drain
Check that the evaporator condensate drain is
secure and connected. Figure 7-3.
Figure 7-3. Evaporator Condensate Drain
Note: Drain tube should be routed through metal
bracket and end of tube should be retained by metal
insert to create a trap. This trap should be lled with
water to prevent air from moving through the tube
and into the cabinet. Sometimes, gurgling sounds
will be heard upon the door closing as the internal
cabinet pressure changes requiring air to be pushed
out which happens through the drain tube trap.

System Operating Pressures
Note: To check operating pressures, you must install access valves onto the process tubes. See Section
7.2.1.
Values in
Table 7-1
represent a range of normal pressures. The measured pressure can vary depending on
ambient conditions and at the point at which unit is in the refrigeration cycle.
Operating pressures shown in
Table 7-1 are nominal and dependent on
many factors (box temperature, position in the
refrigeration cycle, cleanliness of the condenser,
etc.), should only be used as reference.
Never add or remove charge based on the
operating pressures in Table 7-1. These prod
ucts are critically charged and must have the

Air Flow Obstructions
The unit must have free air ow to front grille to
operate properly.
Restricted air ow results in high head pressures
and reduction in efciency due to longer run times.
Proper air ow through condenser and evaporator is
necessary for efcient operation.
• Never obstruct air ow in and out of the
machine compartment.
• The front grille must be free from
obstructions, dust, and debris.
• Never obstruct air ow to Evaporator Fan.
• Make sure higher temperature ambient air from
another unit is not directed to condenser coil
(i.e. another heat source directly across from
the unit).

Figure 7-13. Clean Condenser Coils
Condenser coils that are covered with dust and de-
bris restrict air ow. This results in high head pressures and lower efciency due to longer run times.
Use soft brush and vacuum to clean coil every 90
days, or more often if conditions require.
Ambient Temperature
High ambient temperature and high humidity conditions may result in performance issues and/or refrigeration system failure.
The unit must be protected from precipitation.
Do not subject to direct solar load.
Under extreme temperature and/or relative humidity
conditions the front face, gasket and/or glass door
may show signs of condensation. When temperature
