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
• 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 Commercial Refrigeration
Products.
• Use of these materials will void complete
system 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 problems and compressor damage.
• A nitrogen purge should be utilized when
brazing.
• Flux must not be used on any brazed joints.
Anytime a Perlick Commercial 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.

Air Infiltration
Air infiltration can occur in several locations.
Note: Unit may manifest longer than normal run
times caused by the additional loads that
air infiltration presents.
Signs of air infiltration include:
• Presence of water, moisture or ice
• Condensation on glass or metal surfaces
STEP 1. Door Gaskets
Check door gaskets for rips, cracks, or other
damage.
The door gasket should be pushed in firmly and lay
flat.
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 condenser and the
evaporator compartments. See Figure 6-1.
Check for voids and ensure sealing compound
completely fills the space.
Figure 6-1. Sealing Compound at Wiring Pass-through
STEP 3. Silicone Seal (RTV type)
Check for complete silicone seal of:
• Joint where rear wall meets ceiling
• Around evaporator coil compartment
STEP 4. Floor Drain
Check that interior floor drain plug is in place if not
plumbed to external drain and completely
tightened. Figure 6-2.
Check that the evaporator condensate trap is
looped and full of water. Figure 6-3.

the top center grille and 2 at the bottom edge.
STEP 2.
Remove square bracket around the front of
condensing unit by removing 6 Phillips screws and
2 hex head bolts. Figure 6-4
Pull the square bracket straight out.
Figure 6-4. Remove Condensing Unit Bracket
STEP 3.
The condensing unit/refrigeration deck can now be
pulled straight out. Figure 6-5
Pull slowly and carefully to avoid damaging the
copper line set.
• The copper line set is coiled with enough
additional line to allow condensing unit to be
removed from the cabinet.
• Do not place undue stress on copper lines
when removing condensing unit.
• Damage/kinking of lines may occur if they
are forcibly handled.

System Operating Pressures
Note: To check operating pressures, you must
gain access to the service valves. See
Section 6.4.4.
6.4.1 First Time Pull-Down
After 7 minutes of intermediary speed, the speed is
increased to maximum and it is kept at this
rotation until the thermostat opens, switching the
compressor off.
6.4.2 Normal Cycling
Compressor speed increases and decreases
proportional to thermal load variation during
compressor running time. Minimum speed will be
targeted to minimize energy consumption.
6.4.3 Stabilization
If thermal load remains constant for a period
longer than 20 minutes, the compressor speed is
increased.
Note: The Compressor speed will be adjusted
automatically by the Inverter, in accordance to the
thermal load variation. (variable speed only)
Values in Table 6-1 represent a range of normal
pressures. The measured pressure can vary

Air Flow Obstructions
The unit must have free air flow to front grille to
operate properly.
Restricted air flow results in high head pressures
and reduction in efficiency due to longer run times.
Proper air flow around condensing unit and
evaporator is necessary for efficient operation.
• Never obstruct air flow in and out of
condensing unit.
• The front grille must be free from
obstructions, dust, and debris.
• Never obstruct air flow to Evaporator Fan.
• Make sure higher temperature ambient air
from another unit is not directed to
condenser coil (i.e. another condensing unit
directly across from the unit).
• Never place items in the area behind Product
Side Guard/Handle. See Figure 6-9.
Figure 6-9. Check for Obstructions
Clean Condenser Coil
ELECTROCUTION HAZARD!!
Never attempt to repair or perform
maintenance on the unit until the Main
electrical power has been disconnected.
Perlick’s warranty does not cover cleaning of
condenser.
The condenser is located directly behind the front
grille. See Figure 6-4.
Condenser coils that are covered with dust and
debris restrict air flow. This results in high head
pressures and lower efficiency 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 and/or relative humidity conditions
return to normal condensation will disappear.

Replace Compressor
To gain access to compressor, follow instructions
in Section 6.2.
Compressor should only be replaced with Perlick
OEM parts.
Always replace drier when replacing compressor.
Leak Detection
If during a check of operating system pressures, it
is determined that refrigerant level is low, you
must perform a leak test.
• Do not recharge a system without first
determining where original refrigerant charge
exited the sealed system!
• Placing a system that has lost refrigerant
under a vacuum without first repairing the
leak will draw contaminants into the system
through the point of leak. Find source of the
leak and correct it!
• The use of an electronic leak detector is
highly encouraged.
• If the entire charge has leaked out of the
unit, the sealed system should be pressurized
with 200 lbs. of dry nitrogen and tracer
refrigerant. Then use an ultrasonic leak
detector or a soap and water solution to
pinpoint the location of the leak.
• Be certain to check all brazed connections
thoroughly for leaks. Look for spots where
the sealed system components might have
been worn through by structural or cabinet
components.
• Check the service ports thoroughly for leaks
as well.
Recharge Procedure
STEP 1.
Check that the system been properly installed,
pressure tested, and evacuated.
STEP 2.
Condenser and evaporator must be clean.
Evaporator fan and condenser fan blades must be
able to move the correct amount of air.
STEP 3.
Before installing gauges, vent hoses and manifold
with refrigerant type used in unit. This avoids
introduction of air into system.

existing charge.
Completely reclaim existing refrigerant in
accordance with EPA regulations and thoroughly
evacuate the system.
After evacuating the system:
1. Break vacuum with refrigerant.
2. Purge system through the high side until a
nominal amount of refrigerant is purged out
of the low side.
3. Then “weigh in” the correct total charge into
system.
