All Kairak products are factory tested for performance and are free from defects when
shipped. The utmost care has been taken in crating this product to protect against damage
in transit.
You should carefully inspect your Kairak unit for damage during delivery. If damage is
detected, you should save all the crating materials and make note on the carrier’s Bill Of
Lading describing the damage. A freight claim should be led immediately. If damage
is subsequently noted during or immediately after installation, contact the respective
carrier and le a freight claim. There is a fteen (15) day limit to le freight damage with
the carrier. Under no condition may a damaged unit be returned to Kairak without rst
obtaining written permission (return authorization). You may contact Kairak customer care
at (714) 870-8661 to request a return.
Inspect equipment for shipping damage prior to installation. If shipping damage is found,
save the packing materials and contact the carrier within 5 days of delivery.
Some components are packed and shipped inside the lower 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. If unit is
equipped with shelves, cut and remove the plastic ties holding the shelves in place.
Prep table models 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 sufcient
air circulation of the condensing unit. Failure to provide adequate ventilation may cause
severe compressor damage, and will void warranty.
Place cutting board so that holes in cutting board line up with pins on the counter top.
(See Fig. 2)
Remove louvered panel by lifting up and pulling out entire panel. Slide the lter into the
tracks located below the compressor compartment. Be careful not to catch the lter 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 t inside the opening. (See Fig. 3)
Some units may come with the electric condensate evaporator shipped loose. To install,
attach the two (2) mounting rails to the bottom of the cabinet with 4 or 6 (depending on
the model) #6-32 x 3/8 phillips head screws. Place the condensate evaporator in the
heater bracket. Slide the heater bracket into the mounting rails. Plug the electrical cord
into the heater and the electrical outlet.
(See Fig. 4)
On remote units, refrigeration lines for suction and supply are located on the back of the
unit near the bottom. The suction line is marked “Suction” and is 3/8” copper tubing. The
supply line is 1/4” copper. See “Electrical Connections” section for wiring instructions.
If no holding charge is evident upon opening lines, contact Kairak Service and Parts
Department at 714-870-8661 immediately.
Cut refrigeration tubing with tube cutter (not a hacksaw) and deburr end of tube. Degrease
tubing prior to eld 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.
Refer to the wiring diagram shipped with the unit located inside the compressor
compartment or on the back of the unit.
Plug the unit into a properly sized outlet. See data plate located inside storage cabinet
for circuit sizing.
A junction box located on back of the machine near bottom is provided for electrical eld
connections. See wiring diagram shipped with unit on the back of the unit for electrical
ratings.
Never apply power to a Kairak unit without setting the time clock to the correct time of
day. (Note: All time clocks are preset at the factory to turn the Pan Chiller “off at 12:00
midnight and back on at 5:00 a.m.” unless otherwise instructed by customer).
To set the time of day, rotate the disc clockwise until the arrow lines up the correct time.
Please note that the clock face is divided into 24 hours. (See Fig. 5).
On self-contained units, the time clock is located inside the compressor compartment.
Remove louvered panel by lifting up and pulling out entire panel. Replace louvered panel
by installing top of panel into track and pushing in the bottom so that the locking clips
t inside the opening.
On self-contained units with rear-mounted compressors, the time clock is located on the
side. (See Fig. 7).
On remote units and earlier self-contained models, the time clock is located inside the
lower storage cabinet (See Fig. 9).
If system runs only during normal working hours and food has been removed from pan
chiller at night, the time clock must be set to shut pan chiller off at closing time and to turn
on one hour prior to putting the food in the pan chiller the next day. To change time clock
setting, the tripper pins must be recongured. Each pin on the time clock represents 15
minutes. Tripper pins pulled out away from center of time clock represent refrigeration
off. Tripper pins pushed toward center indicate refrigeration on. (See Fig. 5).
If leaving the food product in the pan chiller overnight, defrost time clock needs to be set
to cycle off and on throughout the night. Time clock must be set to run for 15 minutes
on and 60 minutes off consistently until the night cover is removed the next day. To
change the setting, set the pins to desired cycle times. Each tripper pin represents 15
minutes. Tripper pins pulled out away from center of time clock represent refrigeration
off. Tripper pins pushed toward center indicate refrigeration on. Make sure time clock is
set to correct time of day. (See Fig. 6).
Plastic wrap should be placed over exposed food prior to closing the night cover to help
prevent condensation from getting into the food.
On freezer base units, the defrost time clock is set to defrost 3 times a day for a 15
minute time period. The factory defrost setting is off at 12:00 a.m., 8:00 a.m., and 4:00
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
clock is set to correct time of day. (See Fig. 7)
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.
All temperature settings are preset at the factory but local conditions may necessitate
slight adjustments.
On self-contained the temperature controls are located on
the bottom sides of the unit toward the back of the machine. (See Fig. 8).
On self-contained the temperature control (See Fig. 9) is
located in the compressor compartment. Remove louvered panel by lifting up and pulling
out entire panel. Replace louvered panel by installing top of panel into track and pushing
in the bottom so that the locking clips t inside the opening.
On all remote units and earlier self-contained models, the temperature control is located
inside the lower storage cabinet. (See Fig. 10)
On both self-contained and remote units, the temperature control marked “Pan Chiller”
should be set at 23°F with a 3°F differential. The operating display range should read
between 20°F and 28°F. Temperature control marked “Base Refrigerator” should be set
at 37°F with a 3°F differential. This display should read between 34°F and 40°F. The
temperature control settings are “locked” to avoid unauthorized adjustments. Therefore,
adjustments to the set point must be made by an authorized service technician.
If a freezer base, temperature control marked “Base Freezer” should be set at 0°F with
2°F differential. Temperature display should read between –2°F and 2°F.
A thermometer is provided on all prep table refrigerator and freezer cabinets.
Allow cabinet and pan chiller to reach normal operating temperature before loading
(approximately 1 hour). Frosting of pan chiller plates is normal.
Thermostats are provided to independently control the temperature of the pan chiller and
the lower storage cabinet. The pan chiller system has been supplied with a time clock
for automatic defrost.
(SEE INSTRUCTIONS FOR
SETTING DEFROST TIME CLOCK).
To insure proper food temperatures are maintained in exposed insert pans, the following
conditions are recommended:
1. No direct air blowing on food product from other equipment in the kitchen.
2. Room ambient temperatures of 86°F or less around working area of pan chiller.
3. Food sits a minimum of 1 inch below top of insert pan.
4. All shelving mounted over insert pans (with heated equipment above it) must be
insulated.
5. Occasional stirring of certain foods may be required in order to maintain consistent
temperatures.
6. Some food products chill faster than others i.e., lettuce, diced tomatoes, etc. Double
pans will help prevent over chilling.
7. For remote refrigerators with pan chiller systems, it is imperative that the existing
refrigeration equipment must be sized properly and in good working condition.
The lower storage cabinet is designed to maintain temperatures between 33°F and 40°F
for refrigerated bases, or –2°F to 2°F for freezer bases. 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.
If the prep table and lower storage cabinet are not to be used for an extended period
of time, disconnect the electrical power supply and open the doors (or drawers) to the
lower storage cabinet. As soon as the divider bars have defrosted and the cabinet has
warmed to room temperature, wipe out the pan chiller cavity and base interior.
(FOR PROPER CLEANING
PROCEDURES SEE “MAINTENANCE PROCEDURES”).
Use warm, soapy water to clean lower 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 lower storage cabinet, remove wire shelves. All wire shelves
are adjustable and can be easily removed. Clean shelving 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. 11).
If equipped with tray slides, the tray slides can be removed by lifting up on the front of
the tray slide assembly to allow the front tray slide frame to clear the bottom of the door
opening, then pull the frame assembly out. (See Fig. 12).
If equipped with drawers, remove the drawers from the drawer frame module. The drawer
frame module can be removed by loosening the black clamping knob on the Cross Rail
Locks and Liner Locks. Pull the Cross Rail Locks toward the center of the drawer frame
module and allow the Liner Locks to drop away from the top of the liner. The entire frame
assembly is now free to slide out of cabinet. (See Figs. 13 & 14)
The drain is provided for condensate runoff during the defrost cycle. Use a soft cloth
or sponge to clean the pan chiller. Always exercise caution to avoid getting the fan
assembly wet.
There are two drains in the pan chiller. Both drains must be cleared/cleaned regularly for
proper operation. Drains should be cleaned a minimum of once a month.
The top drain in the pan chiller compartment is typically located at the right end above the
louvered compressor compartment. A removable screen has been provided to prevent
the drain from clogging. (See Fig.15.) Clear drain of dirt and debris so that condensate
can ow freely. This drain is provided for condensate run off from defrosting of chiller
plates.
A second drain located below the fan assembly in the pan chiller must also be properly
maintained and functional. (See Fig. 16). To access this drain, remove the fan shroud
and fan housing assembly. (A 7/16” hex socket is required to remove the fan assembly
cap screws). Clear drain of dirt and debris so that condensate can ow freely. This drain
is provided for condensate run off from defrost cycle.
The condensing unit coil and lter must be cleaned regularly on self-contained models
for optimal performance. The operating environment will affect the required frequency
of cleaning. However, both should be cleaned a minimum of once every three months.
Air must be able to freely circulate through the condenser. Unit performance and
operating efciency are signicantly affected by the amount of air passing through the
condenser. Condenser ns that are clogged with dirt and debris greatly reduce required
airow.
The condensing unit is located behind the louvered panel in
the compressor compartment. Remove louvered panel by pulling on the bottom then
lifting up and out. Remove rear access panel located in the back of unit. A phillips head
screwdriver is required to remove rear 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 lter is located behind the louvered panel, below the condensing unit in the
compressor compartment. Remove lter by carefully sliding out of the tracks. Carefully
clean with vacuum or rinse with hot water exercising care not to bend or damage lter
frame. Replace lter 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 t
inside the opening. Replace rear access panel. Reconnect electrical supply.
The condensing unit is located in the back of the unit, behind
the removable, slotted access panel. The condensing unit coil must be cleaned regularly.
Remove the access panel using a phillips 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 lter. Replace slotted access panel. Reconnect
electrical supply.
Replacement lters are available through Kairak Parts and Service Department at
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 cover.
