SERVICE
ACCESSING CONDENSING COIL
Condensing units on self contained models can
be accessed by removing the louvered panel on
the front of the unit. Lift access panel up and pull
outward to remove.
After removing the louvered panel, remove the
magnetic condenser filter by pulling the filter
framing away from the condenser.
Louvered Panel
Condenser Filter
Filter should be cleaned weekly. It is our
recommendation to have an extra condenser
filter on hand for your unit.

SERVICE
Condensing Coil
ACCESSING CONDENSING COIL
Condenser Coil should be cleaned regularly to
allow air circulation that will ensure proper
operation and efficiency. Failure to clean the coil
at regular intervals can cause compressor
failure and/or malfunction and will void the
warranty. A minimum of a monthly cleaning is
required.
(See operating instructions to prevent premature
failure of components.)
NOTE: CONDENSER COIL FINS SHOULD BE
STRAIGHTEND IF NECESSARY TO ALLOW
PROPER AIR CIRCULATION
WARNING: ANY SERVICE TO THE
CONDENSING UNIT MUST BE PERFORMED
BY AN AUTHORIZED & TRAINED SERVICE
TECHNICIAN
ACCESSING CONDENSING UNIT
To access the condensing unit, remove the
screws (shown in photo) mounting the
condensing guard to the condenser cabinet.
Once the condensing unit is exposed, remove 3
screws in the condensing unit base. 2 screws
are located in the front of the base and the third
is located at the right rear of the base.
11

SERVICE
Once you have removed the screws from the
condensing unit base, the condensing unit will
retract from the condenser cabinet on a sliding
shelf.
There is an additional removable right side panel
for condensing unit accessibility if the installation
of the unit will allow.
Lift panel up and pull the bottom of the panel out
to remove.
REPLACING SNAP– IN GASKETS
Drawer gaskets are critical to maintaining the set
temperature of your unit and should create a
flush seal when the drawers are closed .
Defective gaskets can cause icing, inconsistent
temperatures, food contamination, and
inefficient operation of your compressor.
To Replace:
1. Pull drawer open until it stops, pull back on
slide locks on left and right side retractable
slides ,lift drawer slightly while pulling back
until drawer assembly is removed.
2. Remove gasket by pulling (by hand) from
retaining strip.
12

SERVICE
3. Install new gasket by securely snapping lip
of gasket into retaining strip of door on all
sides.
Retaining Strip
4. Press gasket into retaining strip.
5. Verify proper installation before re-installing
drawer.
6. Re-install drawer to unit.

CLEANING STORAGE CABINET
WARNING: DISCONNECT ELECTRICAL
POWER SUPPLY BEFORE CLEANING ANY
PARTS OF THE UNIT.
STORAGE CABINET: Remove the drawer from
the drawer frame modules, use warm soapy
water to clean storage cabinet doors. NEVER
use cleaners containing gritty, abrasive
materials, bleach or harsh chemicals. Rinse
thoroughly and dry with a clean soft cloth.
Always rub in the same direction as the grain
patter of the stainless steel
WARNING: DISCONNECT ELECTRICAL
POWER SUPPLY BEFORE CLEANING ANY
PART OF THE UNIT
The condensing unit coil must be cleaned
regularly on self-contained models for optimal
performance. The operating environment will
affect the required frequency of cleaning.
However, the condenser should be cleaned at
minimum of once every month. Air must be able
to freely circulate through the condenser. Unit
performance and operating efficiency are
significantly affected by the amount of the air
passing through the condenser. Condenser fins
that are clogged with dirt and grease greatly
reduce required heat transfer to air flow. Failure
to keep the condenser clean may cause
premature compressor failure, which will not be
covered by the warranty. The condensing unit is
located behind the louvered panel in the
compressor compartment. Remove panel by
lifting it up and pulling the bottom out. Carefully
clean dirt and lint from the condenser coil using
a vacuum cleaner or soft brush. Do not use a
wire brush. An approved condenser
degreaser must be used to remove grease.
Replace louvered panel by installing top of the
panel into
track and pushing in the bottom so it fits inside
the opening, reconnect electrical supply.
CONDENSER COILS
WARNING: DISCONNECT ELECTRICAL
POWER SUPPLY BEFORE CLEANING ANY
PARTS OF THE UNIT.
Condenser Coil should be cleaned regularly to
allow air circulation that will ensure proper
operation and efficiency. Failure to clean the coil
at regular intervals can cause compressor
failure and/or malfunction and will void the

CONDENSING COIL PREVENTATIVE
MAINTENANCE (MONTHLY)
NOTE: THE VACUUM “BLOW MODE” IS TO
BE USED WHEN CLEANING THE
CONDENSER COIL.
Follow these steps:
A. Remove grille; use vacuum and soft brush to
dislodge and remove dust on and in the coil.
B. Place damp rags around condensing fan
motor bracket to collect airborne dust.
C. Using vacuum (in blowing mode), blow air
through condenser coil and into the fan.
Make certain to blow entire surface of
condensing coil to assure that all entrenched
dust is removed.

CLEANING CUTTING BOARD
Plastic cutting boards are dishwasher safe. Try
sanitizing with 2 teaspoons of bleach per one
gallon of water. Let stand for a couple minutes,
then rinse and air dry.
All plastic cutting boards wear out over time.
Replace cutting boards that become deeply
scratched, carved or grooved. Boards that are
scored, gouged, and chipped are no longer
cleanable and therefore cannot be effectively
cleaned and sanitized.
FULL DEFROST
Each Chef’s Base is designed to operate with a
regularly scheduled automatic defrost feature but
a monthly full manual defrost is required also.
A. Turn the power off to the unit.
B. Remove all product and pans from the base
cabinet.
C. Leave the unit to set for 24 hours with all of
the drawers removed.
D. After 24 hours, use this time to perform the
monthly case cleaning.
E. Wipe all surfaces dry.
F. Reinstall the drawers and turn the power to
the unit back on.
G. Let the unit cycle down to set temperature
before placing any pre-chilled product into
the drawers.
