2. RECEIPT INSPECTION

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 [phone] or Toll-Free
[phone] to request a return.

3. INSTALLATION

3A - LOCATION:

Unit must be placed on leveled oor for proper usage.

3B - PACKAGING:

Your Kairak unit is shipped from the factory packaged with stretch wrap material.

Most exterior stainless steel surfaces have a protective blue vinyl covering to prevent scratching during
manufacturing, shipping and installation. After the unit is installed in place of application peel, remove and
discard the covering from all surfaces.

The equipment stands are shipped on a skid that is designed to allow a unit to be slid off the skid onto the
factory installed casters. When a unit is being removed from the skid two or more runners will act as slides
and will remain with the unit while it is being removed. These runners prevent damage to the machine

when it drops off the skid to the oor. The runners are retained by the bolts located in the top holes of the

mounting brackets (B).

To unload the machine, remove the exterior packaging. Next remove the retaining brackets. This bracket
is held in place by two bolts into the skid and two screws into the caster channel. There are two of these
brackets per skid segment. Next remove the remaining bolts in the lower holes of the mounting brackets (A)
leaving the bolts in the upper holes (B) in place. Next push the machine off the skid keeping the length of
the machine parallel to the skid’s 4x4 pieces. On longer machines this may require two or more individuals.
When the machine is on its casters the 2x4 runners can be removed by removing the bolts from the top
holes (B) in the mounting brackets. The mounting brackets are removed from the caster channel by twisting

the bracket 90 degrees.

3D - CORD & PLUG:

All self-contained models are shipped standard with a NEMA 5-15P plug and 9 foot cord and spring retainer

attached at the rear of the cabinet. Select only a dedicated electrical outlet for power source.

NOTE: Do not under any circumstances, cut or remove the round grounding prong from the plug, or use
an extension cord.

3E - POWER SUPPLY:

The supply voltage should be checked prior to connection to be certain that proper voltage for the cabinet
wiring is available (refer to the serial tag to determine correct unit voltage). Make connections in accordance

with local electrical codes. Use qualied electricians.

Use of a separate, dedicated circuit is required. Size wiring to handle indicated load and provide necessary
overcurrent protector in circuit (see amperage requirements on the unit’s serial tag).

3F - PLACING EQUIPMENT ON TOP OF UNIT:

Equipment may be placed on top of your Kairak equipment stand. A stainless steel worktop, provided

standard is required on cabinets being used to support equipment weighing in excess of 100 lbs. or
producing heat in excess of 140°F to the top surface. Refer to below chart to determine Maximum Top

Load Capacity for your unit.

4. OPERATION

4A - REFRIGERATORS:

Refrigerators do not require manual defrosting. During normal operation, a refrigerator continuously

circulates above freezing cabinet air through the coil. A compressor “OFF” cycle occurs every 2 1/2 Hours
for 20 minutes to melt any frost which may accumulate on the coil during the compressor “ON” cycle. The

control will read “dEF” and the green water drop will be illuminated. With standard holding refrigerators,
high relative humidity is also maintained to prevent dehydration of stored product.

5. CARE & MAINTENANCE

5A - CLEANING THE CONDENSER/FILTER:

The most important thing you can do to insure a long, reliable service life for your Kairak is to regularly

clean the condenser coil and or lter if provided.

The microprocessor control will notify you through a “CLN-FIL” message when the condensing temperature

of the refrigerator reaches 140 degrees F or greater. If the condensing temperature reaches 160 degrees F the
compressor will automatically turn off . When the temperature drops below 140 degrees F the compressor
will restart and when the temperature drops below 120 degrees F the alarm will reset.

WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING ANY PARTS OF THE
UNIT.

To clean the condenser/lter, rst disconnect electrical power to the cabinet and remove the front louver

assembly. To do so, place hands under the louver panel and pull out and up to get louver panel off bracket
of the unit. See diagram below.

5. CARE & MAINTENANCE (CONTINUED)

5A - CLEANING THE CONDENSER/FILTER (CONTINUED):

Proceed to vacuum or brush any dirt, lint or dust from the nned condenser coil/lter, the compressor and
other cooling system parts. If signicant dirt is clogging the condenser ns or lter, use compressed air to

blow this clear.

To replace the louver assembly reverse the process.

5B - REPLACING THE GASKETS:

To remove the gasket to be replaced, grasp it rmly by one corner and pull it out. Before attempting to install
a new gasket, both the unit and the gasket itself must be at room temperature. Insert the four corners rst

by using a rubber mallet (or hammer with a block of wood). After the corners are properly inserted, work
your way towards the center from both ends by gently hitting with a mallet until the gasket is completely

seated in place (see gure 5 for proper gasket placement).

NOTE: The gasket may appear too large, but if it is installed as indicated above it will slip into place.

5C - CLEANING THE CABINET SURFACES:

WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING ANY PARTS OF THE
UNIT.

Exterior stainless steel should be cleaned with warm water, mild soap and a soft cloth. Apply with a
dampened cloth and wipe in the direction of the metal grain.

Avoid the use of strong detergents and gritty, abrasive cleaners as they may tend to mar and scratch the
surface. Do NOT use cleansers containing chlorine, such as bleach, this may promote corrosion of the
stainless steel.

Care should also be taken to avoid splashing the unit with water, containing chlorinated cleansers, when

mopping the oor around the unit.

For stubborn odor or spills, use baking soda and water (mixed to a 1 tbsp baking soda to 1 pint water

ratio).

A stainless steel polish is recommended for shining of unit.

7. MICROPROCESSOR CONTROL

Your new refrigerator cabinet is equipped with a state-of-the-art microprocessor control, which
precisely regulates operation and provides alarms when problems occur. It is supplied from the factory
completely ready for use and requires no adjustments, but without the audible alarms activated. See

pages 10 thru 26 for more information.

MICROPROCESSOR CONTROL

FIG. 8

7A - CONTROL FEATURES:

1 - INTERNAL TIME CLOCK

• Eliminates external defrost time clock.

• Defrost cycle can be quickly adjusted to suit individual location and use.

• Must be set at power-up. (See page 17, “Setting the 24-Hour Clock”)

• Will automatically update for Daylight Savings Time.

2 - WATER RESISTANT HOUSING

The face of the control is water resistant to provide for protection during cleaning.

3 - PARAMETER/SERVICE LEVELS

• See “Customer / Service Parameters” on Page 14.

4 - DEFROST LOCKOUTS

Customers can set up to 4 different defrost lockout periods. The lockout prevents the unit from going into
a defrost cycle during peak kitchen use.

(See “Setting Defrost Lockouts” on page 21)

Note: The 24-hour clock must be set for this feature to operate correctly.

5 - COMMUNICATION ABILITY

A NAFEM Data Protocol (NDP) compliant RS-485 serial communications port is available to interface with data

collection software (by others). All microprocessor control equipped models are capable of communicating
within a NAFEM Data Protocol network if provided with an optional Gateway Hub (available from Kairak).
The actual communications software is available from a number of third party software vendors.

6 - ANTI-CONDENSATE DOOR PERIMETER HEATER CONTROL

The “No-Sweat” feature is an energy savings system that allows the customer to adjust the percent of

time for the drawer heater to be “On” as needed for the prevailing ambient conditions (from 0 - 100% of

the time each day). It is used to prevent condensation from forming around the perimeter of the drawers.

The factory default setting is 100%. Adjust this set point down to a point just before condensation forms

to save energy.
