UNPACKING
Inspect equipment for shipping damage prior to installation. If shipping damage is
found, save the packing materials and contact the carrier within 15 days of delivery.
Some components are packed and shipped inside the storage cabinet to avoid damage
during shipment. Remove these items from the cabinet and remove packing materials.
See “Installing Parts Shipped Loose" for installation instructions. Cut the plastic ties
holding the shelves in place.
LOCATING THE EQUIPMENT
Any model of lengths above 36” can be installed with no clearance at the back and
sides of the units. Units 36” or shorter have a rear mount compressor and require a
minimum clearance of 3 inches at the back and sides of the unit. This allows for
sufficient air circulation of the condensing unit. Failure to provide adequate ventilation
may cause severe compressor damage, and will void warranty.
INSTALLING PARTS SHIPPED LOOSE
Compressor Filter
Remove louvered panel by lifting up and pulling out entire panel. Slide the filter into the
tracks located below the compressor compartment. Be careful not to catch the filter on
sharp edges when installing. Replace louvered panel by installing top of panel into
track and pushing in the bottom so that the locking clips fit inside the opening. (See Fig.
2 ).

WARNING: REFRIGERATION LINES ARE SHIPPED UNDER PRESSURE. USE
CAUTION WHEN OPENING LINES.
On remote units, refrigeration lines for suction and supply are located on the back of the
unit near the bottom. The suction line is tagged and marked “Suction”. The suction line
is 3/8” copper for units 27 inches to 55 inches in length, and 1/2” for units 56 inches to
120 inches in length. The supply line is 1/4” copper for units 27 inches to 55 inches in
length, and 3/8” for units 56 inches to 120 inches in length. See “Electrical
Connections” section for wiring instructions.
If no holding charge is evident upon opening lines, contact Kairak Warranty Department
at 310-539-1443 immediately.
Cut refrigeration tubing with tube cutter (not a hacksaw) and deburr end of tube.
Degrease tubing prior to field connection. Use Silfos 5% for refrigerant line brazing.
50/50 or cold solder is not acceptable.
For system charge, follow remote refrigeration system manufacturer’s instructions.
ELECTRICAL CONNECTIONS
Refer to the wiring diagram shipped with the unit located inside the compressor
compartment or on the back of the unit.

Defrost Time Clock Settings for Units with a Freezer Base
On units with a freezer base, the defrost time clock is set to defrost 3 times a day for a
15 minute lime period, The factory defrost setting is off at 12:00 a m., B:O0 am, and
2:00 p.m for 15 minutes each. To change this setting, set the pins to desired off times.
Each pin represents 15 minutes. Pins pulled out away from center of time clock
represent refrigeration off. Pins pushed toward center indicate refrigeration on. Make
sure time dock is set to correct time of day.
To set the time of day, rotate the disc in the direction of the arrows (clockwise rotation)
to align the hands to the correct time of day.
Temperature Contra t Settings
All temperature settings are preset at the factory but local conditions may necessitate
slight adjustments.
On self-contained models KRUCfKRWT-27S through KRUCJKRWT-3GS the
temperature controls are located on the bottom sides of the unit toward the back of the
machine. (See Fig. 4).

On both self-contained and remote units, the temperature control should be set at 37°F
with a 3°F differential. This display should read between 34°F and 40°F. The
temperature control setting is “locked” to avoid unauthorized adjustments. Therefore,
adjustments to the set point must be made by an authorized service technician.
If a freezer base, the temperature control should be set at 0°F with 2°F differential.
Temperature display should read between -2°F and 2°F.
OPERATION
A thermometer is provided on all refrigerator and freezer cabinets.
Allow cabinet to reach normal operating temperature before loading (approximately 1
hour).
The refrigerated storage cabinet is designed to maintain temperatures between 33°F
and 40°F, or -10°F to 0°F for a freezer storage cabinet. If the base is overloaded with
warm food products, a certain amount of time is required to remove heat from items
before operating temperatures can be maintained. The system is designed for storage
of refrigerated or frozen product.
Frequently opening the doors or drawers will increase the temperature in the cabinet
and will require a certain amount of time to recover.
To Shutdown for an Extended Period of Time
If the units are not to be used for an extended period of time, disconnect the electrical
power supply and open the doors (or drawers) to the storage cabinet. As soon as the
cabinet has warmed to room temperature, wipe out the base interior.
MAINTENANCE PROCEDURES
CLEANING
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING
ANY PARTS ON THE UNIT.
STORAGE CABINET
Use warm, soapy water to clean storage cabinet and doors. NEVER USE cleaners
containing grit, abrasive materials, bleach or harsh chemicals. Rinse thoroughly and

dry with a clean soft cloth. Always rub in the same direction as the grain pattern on the
stainless steel.
To clean the inside of the storage cabinet, remove wire shelves, tray slides, or drawer
mod. If equipped with shelves (KRUC/KRWT only), all wire shelves are adjustable and
can be easily removed. Clean shelves in a sink. If shelf clips have been removed,
make sure the four clips per shelf are at same height in pilaster. The shelf clips have a
small projection on top which holds the shelf in position and prevents it from slipping
forwards. The clip must be “snapped” in place by squeezing clip together and inserting
into slot in pilaster keyhole. (See Fig. 8).
Fig. 8
If equipped with tray slides (KRUC/KRWT only), the tray slides can be removed, using a
philips head screwdriver, by removing the screws securing the tray slide assembly to
the breaker strips, then pulling the frame assembly out. (See Fig. 9).

Condensing Unit
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING
ANY PARTS ON THE UNIT,
The condensing unit coil and/or filter must be cleaned regularly on self-contained
models for optimal performance. The operating environment will affect the required
frequency of cleaning. However, coils should be cleaned a minimum of once every
three months. Air must be able to freely circulate through the condenser. Unit
performance and operating efficiency are signtficandy affected by the amount of air
passing through the condenser. Condenser fins that are clogged with dirt and debris
greatly reduce required airflow. Failure to keep clean may cause premature
compressor failure, which will not be covered by warranty. (On models that
contain filters, operating unit without filter will void warranty).
KRUCfKRWT Units 27-36 inches in length: The condensing unit is located in the
beck of the unit, behind the removable, slotted access panel The condensing unit coil
must be cleaned regularly. Remove the access panel using a philiips head screwdriver.
Carefully clean dirt and lint from the condenser coil using a vacuum cleaner or soft
brush; do not use a wire brush. These units do not have a removable filter. Replace
slotted access panel. Reconnect electrical supply.
KRUCJKRWT Units 37-1ZO Inches in Length and all KRES self-contained units:
The condensing unit is located behind the louvered panel in the compressor
compartment Remove access panel located in the back of unit. A phillips head
screwdriver is required to remove access panel. Carefully clean dirt and lint from the
condenser coil using a vacuum cleaner or soft brush, do not use a wire brush.

The filter is located behind the louvered panel, below the condensing unit in the
compressor compartment. Remove louvered panel by lifting up and pulling out entire
panel. Remove filter by carefully sliding out of tracks. Carefully clean with vacuum or
rinse with hot water exercising care not to bend or damage filter frame. Replace filter by
carefully sliding it into the tracks. Replace louvered panel by installing top of panel into
track and pushing in the bottom so that the locking clips fit inside the opening.
Replace rear access panel. Reconnect electrical supply.
Replacement filters are available through the Kairak Warranty Department at 310-539-
1443.
Evaporator Coils
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING
ANY PARTS ON THE UNIT.
Evaporator coils should be cleaned every six (6) months for optimal performance.
The evaporator coils are located in the storage cabinet behind the coil can cover. With
a phillips head screwdriver, remove four screws and take off cover. Clean evaporator
coils with a vacuum cleaner or soft brush, do not use a wire brush. Replace coil can
