Section 2
Installation
DANGER
Installation must comply with all applicable fire and
health codes in your jurisdiction.
DANGER
Legs or casters must be installed and the legs or casters
must be screwed in completely to prevent bending.
When casters are installed the mass of this unit will
allow it to move uncontrolled on an inclined surface.
These units must be tethered/secured to comply with
all applicable codes.
DANGER
Use appropriate safety equipment during installation
and servicing.
DANGER
Do not lift the condensing unit by the refrigerant tubing
or other components. These features will not support
the condensing unit weight. Injury and unit damage
may occur!
DANGER
This equipment contains refrigerant charge. Installation
of the line sets must be performed by a properly trained
and EPA certified refrigeration technician aware of the
dangers of dealing with refrigerant charged equipment.
Warning
n
Use a jack to lift the refrigeration unit off the ground
just far enough to remove the leg/caster. Place blocking
underneath the unit. Do not work underneath a raised
unit without proper blocking. Do not lift the unit more
than necessary to remove the leg/caster. Lifting the unit
too far can make the unit unstable.
Warning
n
Do not damage the refrigeration circuit when installing,
maintaining or servicing the unit.
Warning
n
Remove all removable panels before lifting and
installing.
Notice
After installing casters, the unit must stand upright for
twenty-four (24) hours before being powered up to
assure oil return to the compressor sump.
Notice
Optional sink water heater MUST be filled with water
before connecting the water heater to power to prevent
damage to the heater.
Notice
The units with LiquiTec technology cold pans contain a
non-toxic eutectic fluid within a sealed inner liner. This
fluid may leak if the tank is punctured so care must be
taken when uncrating and setting in place. The eutectic
fluid is non-toxic and may be flushed down a disposal
drain. Units with a Eutectic Fluid Cold Pan require the
same precautions. The fluid is NOT refillable and loss
of fluid due to a puncture would cause irreparable
damage. If the LiquiTec unit cold pans leak, immediately
call KitchenCare 1-844-724-CARE (2273).
Warning
n
Be sure all cooking equipment resting on the equipment
stand is properly anchored. Consult the manufacturer’s
instructions for the cooking equipment to determine
the proper mounting technique. It is the owner’s and
operator’s responsibility to securely anchor cooking
equipment to the equipment stand.

Operation Section 3
Controls/Programming/Settings
FROST TOP CARTS
Frost tops are designed to maintain an even layer of frost to
pleasantly display product. Once turned on, the compressor
will run continuously. There is no temperature control. The
ON/OFF switch is the only means available to cycle the unit.
Since it takes time for the frost to accumulate initially, the
unit should be turned on approximately one hour before
it is actually required. Product should not be placed on the
frost top prior to turning the unit on, because it may freeze
to the surface of the unit.
The unit must be turned off when not in use or overnight
for defrosting and cleaning.
HEATED AND REFRIGERATED COMBO CARTS
Combo carts are constructed of separate hot and cold wells
with separate controls. Use the refrigerated cart setting
information for the cold portion of the combo cart. Use the
heated cart setting information for the hot portion of the
combo cart.
REFRIGERATED CARTS
Mechanically cooled and LiquiTec series cold pans are
adjusted at the factory to provide proper operation without
any further adjustments.
It may become necessary to adjust the temperature.
Temperature in a mechanically cooled pan is controlled by
a pressure control, see page 23. LiquiTec cold pans have
a thermostat located in the machine compartment. Turn
the knob clockwise as indicated on the control. Settings
are from 1 thru 7 (7 being the coldest). Adjustments should
be made gradually. Several small adjustments will be more
effective than one large adjustment. It may take an hour or
longer to realize the temperature change depending on the
application and location of the unit.
If the mechanical cold pan is to be used with ice, it is
recommended that the optional perforated bottoms be
used. These will allow ice to melt properly.
LiquiTec cold pans are not intended to be used with ice.
Turn LiquiTec cold pans ON an hour prior to use to allow for
ample cool down time.
These units are not designed to cool warm food products.
Items should be placed in the unit cooled at least to the
desired holding temperature, if not slightly colder. In some
applications, a gradual warming of product may occur,
particularly at the exposed top of the products. Stirring
or rotation of the product is necessary to maintain overall
temperature. Warming of food product can occur very
quickly outside of the unit. When loading or rotating the
product, avoid leaving food items in a non-refrigerated
location for any length of time to prevent warming or
spoilage. To ensure product quality product must be
rotated every four hours. Always place covers on pans when
not serving to maintain temperatures.
The unit must be turned off when not in use or overnight
for defrosting and cleaning.

Section 3 Operation
HEATED CARTS
Select desired temperature by rotating the knob on the
temperature control panel. Indicator light will come on
when the switch is activated. Individual temperature
control knobs and indicator lights are provided for each
heated food well.
If the same temperature settings for each well are used
every day, the temperature knobs can be left in their set
position and the wells can be turned off using the ON/OFF
switch at the end of the control panel.
Before the unit is used the first time for serving, turn the
temperature knob to “10” and heat the well for 15 minutes.
Do not be alarmed if smoke appears; this preheat should
burn off any residue or dust that has adhered to the food
well element.
When serving thick sauces always use the hot food well in
“wet” operation. This provides more uniform temperature
for the sauce. Product temperature should range from
140˚F to 160˚F.
Caution
,
Never place food directly in well. Always use pans.
Heated Carts Dry Operation - 1000 Watt
Warning
n
When hot wells operated dry, the well bottoms become
very hot. Do not allow unprotected skin to contact any
well surface.
The heated units may be operated without water with no
damage to the unit. Wet operation is usually much more
efficient and is usually preferred.
When operated dry, the bottom of the well will discolor. To
clean, use a stainless steel cleaner or mild abrasive.
Optional Heated Understorage
If necessary, preheat the heated understorage to desired
temperature. Temperature range of understorage is 100°F
to 200°F (38°C to 93°C). The temperature control knob is
always the far left knob on the panel. Indicator light is also
at the far left.
For most efficient operation, keep covered insets empty
in each well during preheating and when the well is not in
use.
Always place covers on pans when not serving to maintain
temperatures, prevent food from drying out and to reduce
your operating costs.
Heated Carts Wet Operation
Warning
n
Steam can cause serious burns. Always wear some type
of protective covering on your hands and arms when
removing lids from the unit. Lift the lid in a way that will
direct escaping steam away from your face and body.
Water temperature will average 180°F (82.2°C).
Fill the food well with about 2 in (51mm) of water and cover
with lid or empty pan. To preheat water, set temperature
control at “High”. With pans in place, wells will boil water.
Food temperature will vary depending on type and
amount of product. To minimize steam and water usage,
set control to lowest setting that will maintain proper food
temperature.
To reduce preheating time, use hot water to fill the well.
Part Number: 9291536 8/14 19
Operation Section 3
MILK AND ICE CREAM CARTS
To begin operation plug the electrical supply cord into a
receptacle with the correct voltage. Each combination unit
is constructed with two separate tanks. Follow the milk cart
and the ice cream cart directions respectively for loading
and defrosting.
The milk tank is set at the factory to maintain temperatures
between 36°F and 40°F (2°C and 4°C). No further adjustment
should be necessary. If a temperature adjustment is
necessary the milk tank temperature is controlled by a
thermostat located in the machine compartment. Turn the
knob clockwise as indicated on the control. Settings are
from 1 thru 7 (7 being the coldest). Adjustments should be
made gradually. Several small adjustments will be more
effective than one large adjustment. It may take an hour
or longer to realize the temperature change depending on
the application and location. The ice cream tank is set at
the factory to maintain temperatures between -5°F and 0°F
(-15°C and -18°C). If a temperature adjustment is necessary
follow the pressure control directions on page 23.
MILK CARTS
Milk carts are set at the factory to maintain temperatures
between 36°F and 40°F (2°C and 4°C). No further
adjustment should be necessary. If a temperature
adjustment is necessary follow the pressure control
directions on page 23. To begin operation plug the
electrical supply cord into a receptacle with the correct
voltage.
To load, place a complete layer of cartons or bottles
standing upright on the load tray. Then place a divider tray
on top of this layer, then another layer of cartons or bottles
on this tray, then another tray and another layer, etc. As
each additional tray is loaded, the elevators gradually lower.
The last layer may be placed on top without the use of
another tray. When loading the average tall half pint bottles,
four layers may be loaded into each compartment standing
upright and the fifth layer laying down. Always use covers
when not serving to maintain temperatures.
ICE CREAM CARTS
Ice cream carts are set at the factory to maintain
temperatures between -5°F and 0°F (-15°C and -18°C). No
further adjustments should be necessary. If a temperature
adjustment is necessary follow the pressure control
directions on page 23. To begin operation plug the
electrical supply cord into a receptacle with the correct
voltage.
To load, place two layers of ice cream on the load tray, then
a tray, two additional layers of ice cream, then another
tray, etc. Do not stack ice cream above the frost line on the
interior of the freezer. Always use covers when not serving
to maintain temperatures.
Ice cream carts require defrosting after 0.375 in to 0.5 in
(10mm to 13mm) of frost forming. Never use sharp objects
or tools to clean or scrape ice/frost build up from the
refrigerated cold pans or frost tops. A puncture to the pan
could cause irreparable damage to the refrigeration system.
Important
Use the divider trays provided between each successive
layer of contents to assure the correct balance of the
load and the proper action of the elevating mechanism.
Wire racks, when used, should be loaded completely. When
placing one rack on top of the other, be sure the stacking
lugs are properly aligned.
Milk carts require defrosting after 0.375 in to 0.5 in (10mm
to 13mm) of frost forming. Never use sharp objects or tools

position. Drain water and allow unit to cool before cleaning
or switching to cold operation.
Optional N8600 Cold Operation
Simply place the function switch to the COLD position.
The compressor controller has been factory set and no
temperature adjustment should be necessary. If the cold
pan is to be used with ice, it is recommended that the
optional perforated bottoms be used. These will allow ice to
melt properly.
These units are not designed to cool warm food products.
Items should be placed in the unit cooled at least to the
desired holding temperature, if not slightly colder. In some
applications, a gradual warming of product may occur,
particularly at the exposed top of the product. Stirring or
rotation of the product is necessary to maintain overall
temperature.
Warming of food product can occur very quickly outside
of the unit. When loading or rotating product, avoid
leaving food items in a non-refrigerated location for any
length of time to prevent warming or spoilage. To ensure
product quality product must be rotated every four hours.
Always place covers on pans when not serving to maintain
temperatures.
Optional N8600 Switching From Hot To Cold Operation
1. Place the function switch in the OFF position and drain
out hot water.
2. Allow the unit to cool until it can be safely cleaned.
3. When clean up procedures are complete, unit will be
ready for cold operation. This takes about one hour.
Notice
To assure maximum compressor life, do not switch
from “hot” to “cold” operation without allowing a cool
down period. Never switch from hot to cold operation
while hot water remains in the pans. Failure to observe
this warning will greatly reduce compressor life and
eventually cause premature compressor failure.
Optional N8600 Switching From Cold To Hot Operation
No special procedure is required to switch from the cold to
hot operation. Be certain to fill will with a minimum of 4 in
(102mm) of water.
Caution
,
The unit is designed so that the compressor and the
heating elements cannot operate at the same time.
Continued operation of the compressor in the “hot
position” is not normal.
The unit must be turned off when not in use or overnight
for defrosting and cleaning.
N8600 Immersion Heater High Limit
As a safety feature, the N8600 food well immersion heater
includes a high limit safety switch. If the heater gets too
hot the safety switch will trip and turn the heater off. A
pilot light on the control panel will illuminate when the
safety switch is tripped. To reset the safety switch, first turn
OFF the thermostat or Power switch and then determine
if low water is the cause. If low water is not the cause,
contact service for resolution. If low water is the cause,
carefully remove food pans and refill the water. This will
allow the immersion heater to cool and the safety switch
will automatically reset. The unit must be turned OFF
as directed or safety switch will not reset even if water
is refilled to proper level. Replace food pans and turn
thermostat or Power switch back on.

PRESSURE CONTROL
The models below have an adjustable pressure control
that controls the temperature. It is located in the machine
compartment. They are field adjustable and do not require
a service agent. The adjustable control has the word
COLDER near the knob, with an arrow to indicate the
adjustment direction. Make small incremental adjustments
if a temperature adjustment is necessary.
Caution
,
In attempting to adjust the pressure control, you can
do damage to your unit by accidentally adjusting the
differential.

EXTERIOR CLEANING
Notice
When cleaning interior and exterior of unit, care should
be taken to avoid the front power switch and the rear
power cord. Keep water and/or cleaning solutions away
from these parts.
Notice
Never use a high-pressure water jet for cleaning or hose
down or flood interior or exterior of units with water. Do
not use power cleaning equipment, steel wool, scrapers
or wire brushes on stainless steel or painted surfaces.
The interior can be cleaned using soap and warm water. If
this isn’t sufficient, try ammonia and water or a nonabrasive
liquid cleaner.
Never use an acid based cleaning solution on exterior
panels! Many food products have an acidic content,
which can deteriorate the finish. Be sure to clean the
stainless steel surfaces of ALL food products.
Clean the area around the unit as often as necessary to
maintain cleanliness and efficient operation.
Wipe gasket and surfaces with a damp cloth rinsed in water
to remove dust and dirt from the outside of the unit. Always
rub with the “grain” of the stainless steel to avoid marring
the finish. If a greasy residue persists, use a damp cloth
rinsed in a mild dish soap and water solution. Wipe dry with
a clean, soft cloth.
Never use steel wool or abrasive pads for cleaning. Never
use chlorinated, citrus based or abrasive cleaners.
Fiberglass and stainless steel exterior panels have a clear
coating that is stain resistant and easy to clean. Products
containing abrasives will damage the coating and
scratch the panels. Daily cleaning may be followed by an
application of stainless steel cleaner or polish which will

eliminate water spotting, fingerprints and bring out the
color of the fiberglass. Fiberglass surfaces should be waxed
twice a year. Early signs of stainless steel breakdown are
small pits and cracks. If this has begun, clean thoroughly
and start to apply stainless steel cleaners in attempt to
restore the steel.
COUNTER PROTECTOR GLASS & HARDWARE CLEANING
Notice
Never use window sprays or kitchen scouring
compounds to clean plexiglas.
Clean daily with soap and water. Extreme stains or grease
should be cleaned with a nonabrasive cleaner and plastic
scrub pad. Polish the chrome when necessary with a soft
cotton cloth.
DRAIN
Each unit has a drain located inside the unit that removes
the condensation from the evaporator coil and routes it
to an external condensate evaporator pan. Each drain can
become loose or disconnected during normal use. If you
notice water accumulation on the inside of the unit, be sure
the drain tube is connected to the evaporator drain pan. If
water is collecting underneath the unit, make sure the end
of the drain tube is in the condensate evaporator in the
machine compartment. The leveling of the unit is important
as the units are designed to drain properly when level. Be
sure all drain lines are free of obstructions.
CLEANING THE CONDENSER COIL
In order to maintain proper refrigeration performance, the
condenser fins must be cleaned of dust, dirt and grease
regularly. It is recommended that this be done monthly. If
conditions are such that the condenser is totally blocked
in a month, the frequency of cleaning should be increased.
Clean the condenser with a vacuum cleaner or stiff brush. If
extremely dirty, a commercially available condenser cleaner
may be required.
Failure to maintain a clean condenser coil can initially cause
high temperatures and excessive run times. Continuous
operation with a dirty or clogged condenser coil can
result in compressor failure. Neglecting the condenser coil
cleaning procedures will void any warranties associated
with the compressor and cost to replace the compressor.
DEFROSTING
Refrigerated cold pans and frost tops should be defrosted
daily. Milk or Ice Cream dispensers require defrosting after
0.375” to 0.5” (10 mm to 13 mm) of frost forming. ON/OFF
switch is located above louver panel.
Caution
,
Never use sharp objects or tools to clean or scrape ice/
frost buildup from the refrigerated cold pans or frost
tops. A puncture to the pan could cause irreparable
damage to the refrigeration system.
Units with a Eutectic Fluid Cold Pan require the same
precautions. The fluid is NOT refillable and loss of fluid
due to a puncture would cause irreparable damage.
DOORS/HINGES
Over time and with heavy-use doors, the hinges may
become loose. If this happens, tighten the screws that
mount the hinge brackets to the frame of the unit. Loose
or sagging doors can cause the hinges to pull out of the
frame, which may damage both the doors and the hinges.
In some cases this may require qualified service agents or
maintenance personnel to perform repairs.
PREVENTING BLOWER COIL CORROSION
To help prevent corrosion of the blower coil, store all acidic
items, such as pickles and tomatoes, in seal-able containers.
Immediately wipe up all spills.
FIELD INSTALLATION
Over shelves and other items mounted to the top of the
counters should never be installed in the field due to the
potential damage to the refrigeration system.
CASTERS
Wipe casters with a damp cloth monthly to prevent
corrosion.
