2.3 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
isimportantforthesafeandecientservice,
operation and care of the Perlick unit.
HAZARD!! Indicates hazardous situation that
will result in death or serious injury if not
avoided.
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.
• Vacuum pumps must be explosion-safe. It must
be possible to lead the discharge air from the
vacuum pump into open air.
• Leak detection cannot take place with normal
halogen leak detectors, as they do not react on
hydrocarbons. A special detector reacting on
a hydrocarbon must be used instead. Another
possibility is to use a leak spray. Both solutions
only work properly if the vapor pressure in
the system is higher than 1 bar (atmospheric
pressure).
• If the pressure is lower than the normal
atmospheric pressure, it is necessary to raise
the pressure within the system to ambient
temperature.
Never use liquid to detect system leaks if
system is in a vacuum!
All self-contained models covered in this service
manual are manufactured using refrigerant
HC-600a (Isobutane).
2.2 Servicing with R-600a
R600a is a hydrocarbon. This refrigerant is
ammableandisonlyallowedforuseinappliances
whichfullltherequirementsofUL60335-2-24
(To cover potential risk originated from the use of
ammablerefrigerants).Consequently,R600ais
only allowed to be used in household appliances
whicharedesignedforthisrefrigerantandfulll
the above-mentioned standard.
• R600a is heavier than air. The concentration
willalwaysbehighestatoorlevel.
• The explosion limits are as follows:
Lower limit: 1.5% by vol. (38 g/m3)
Upper limit: 8.5% by vol. (203 g/m3)
Ignition temperature: 460°C
2.2.1 General
Do not use near open re. To carry out service
and repair on R600a systems the service personnel
must be properly trained to be able to handle a
ammablerefrigerant.Thisincludesknowledge
on tools, transportation of compressors and
refrigerant, and the relevant regulations and safety
precautions when carrying out service and repair.
2.2.2 Transportation of refrigerant and
replaced compressors
• The refrigerant must be stored and transported
in approved containers.
• Replaced compressors containing refrigerant
residues must be sealed before being
transported.
2.2.3 Tools
Ingeneral:Noopenrewhentroubleshootingand
repairing.
• The refrigeration circuit must be opened with a
tube cutter or a special tool.

See Figure 6-2.2.
Check for condensation or cold air around the top
perimeter of the refrigeration module, or using a
bright light, shine the light at the gasket and look
for light on the other side of the gasket. If any
condensation, cold air or light can be detected
around the gasket, remove the refrigeration module

6.11 Leak Detection
IF A LEAK IS SUSPECTED, VENTILATE THE
AREA AND ENSURE THERE ARE NO NEARBY
IGNITION SOURCES.
Isobutane (R-600a) is a low pressure refrigerant
(30 PSIG @ 70°F). If checking for a leak, the
system should be at a minimum temperature of
70°F.
Use an isobutane (R-600a) compatible electronic
leak detector, check all joints, tubing and coils
for leaks. If a leak is detected, replace the
refrigeration module (
see Section 6.6
).

7.1.4 Replacing
To replace the control board:
1. Remove any shelving or product that will
interfere with accessing the inner ceiling of the
cabinet.
2. Once the inner ceiling is accessible, lower the
carbonlterhousingbypullingonthefront
edge to release the latch and mate connector
andremovethecarbonlter.
3. Remove the wire channel cover in the left rear
corner by removing the fasteners holding it in
place.
4. Next remove the two (2) fasteners located
ontherearangeofthecover,thatholdthe
control cover panel to the ceiling. For the
freezer and wine models slide the cover back
a ½” to disengage the tabs that mate with the
user interface bracket. For the refrigerator, pull
forward on the cover to disengage the open
hemangeonthefrontofthecover.
5. Slowly lower the cover and remove the bushing
that protects the wires going through the wire
access hole.
6. Remove the wires through the key slot hole
and set the cover panel aside. The control
board is now visible. (If desired for the freezer
and wine models, the user interface can be
removed). (
See Section 7.2.
).
7. Disconnect all wire harnesses from the control
board, noting connecting locations if required.
8. Remove the 4 fasteners that hold the control
board to the ceiling (support the control
board).
9. Replace with new control board, installing in
reverse steps.
10. Ensure all electrical connections are correct and
properly engaged.
7.2 User Interface
If user interface is not operational, check electrical
connections from the control board to the user
interface. Use Control Replacing (
see section
7.1.4.
) instructions to access the control board and
user interface connections. For a refrigerator, there
is a third connection located at the rear of the
user interface housing, to access, remove the deli
bin glass lid by removing the two pivot fasteners,
one on each end of the lid, then pull the two pins
on the edges of the user interface housing and
pull out on the housing. If connections are good,
replace the user interface assembly.
Replacing
Freezer and Wine
See Control Replacing instructions (
see section
7.1.4.
). Once the control board is accessible,
remove the two fasteners, one on each inner
end of the user interface bracket. Slide the user
interfaceassemblyforwardtoreleasetheangeon
the front top. Once loose, disconnect the harness.
Replace following reverse instructions.
Refrigerator
The user interface housing is the complete sheet
metal housing that contains the user interface. To
remove the housing, remove the deli bin glass lid
by removing the two (2) pivot fasteners, one on
each end. Next, pull the two retaining pins from
the left and right edge of user interface housing.
Finally, pull out the housing, it will slide along the
rails, manage the wire harness and disconnect
before pulling completely out of the rails. Early
models may require removal of the left rear wall
cover panel to access the third connector. To
remove that panel, remove all shelving, remove
thecenterandleftpilasterandnallyremove
the panel. Locate the connector and disconnect.
Replace with a new user interface assembly
and complete user interface wire harness so the
connection is at the rear of the housing.

based on temperature, ensure that the probe is at
a stabilized temperature.
For the temperature and humidity sensors used

and fully extend. Locate the release mechanism
on each slide and pull forward on the release
mechanisms and pull the shelf out. To remove
the slide member from the cabinet pilaster, simply
lift-up evenly and pull forward. Support the slide to

shelf slide member is parallel with the cabinet slide
member. Do not force together as this can result
in damage to the ball bearing retainer and result
in ball bearings dislodging from the retainer. Once
engaged, push the shelf in until shelf slide is fully
retracted, then pull the shelf out to full extension
to ensure the slide lock mechanism is engaged.
Finally, push the shelf in until the soft-close
mechanism engages and fully retracts the shelf
into position.
