FEATURES & SPECIFICATIONS
Forced Convection Fried Food Holding Cabinet
The Crisp n’ Hold provides a heated stream of air to maintain fried food temperature and freshness for
a specified period of time after cooking. Forced air is heated through an electric resistance heater and
ducted to a food grate. The heated air is discharged through small circular openings in the bottom of
the grate and through a slotted opening located front top to provide a warm blanket of air over the food.
Additionally, the grate has small round embossments to minimize hot metal contact with the food. Ad-
justable and removable food dividers.

Refer to FREIGHT DAM-
AGE CLAIM PROCEDURE
below.
INSTALLATION
Location
For proper operation and maximum performance, locate the Crisp n’ Hold in an ambient air tempera-
ture of 70º F (21ºC).
Avoid areas near exhaust fans where there is active air movement. For safe operation, locate the
unit a reasonable distance from combustible walls and materials.
To prevent injury and damage, locate the unit at a proper and safe working height. The location
should be level, clean of debris, and strong enough to support the weight of a fully loaded unit.
To prevent electrical shock, be sure unit is not plugged into an electrical outlet. If unit has been oper-
ated, allow to cool before installing.

Countertop Mounting
NOTE: CNH12LP and CNH18LP drop-in models are not in-
tended to be dropped into an enclosed compartment. Counter
must be made of a non-combustible material, located away
and shielded from combustible materials, clean and free of
debris. Locate and drill four mounting holes in counter top.
If desired, you may remove the legs from unit and secure to
counter top using threaded mounting holes previously occu-
pied by legs. Seal the perimeter of
unit where it meets the counter top
with a food grade silicone sealant.
Drop-In Mounting
Counter-top must be non-
combustible and made of stainless
steel, clean and free of debris. Veri-
fy cut-out dimensions of the counter
-top. CNH12LP: 20.75”D x 24.25”
W; CNH18LP: 20.75”D x 30.25” W.
Warmer is equipped with Carter-
Locks, uniquely designed turn-out
tabs which secure the top flange of
the warmer to the counter top.
Apply food-grade silicone sealant to
the underside of the warmer top
flange prior to setting the unit into the
cutout. Set the warmer into the coun-
ter top cut-out.
After installation, verify that the tabs on the CarterLocks are
turned out to lock the warmer into the counter. A flathead
screwdriver may be used to turn the tabs.
Apply a thin bead of food-grade silicone sealant around the
flange to seal it to the counter.
INSTALLATION
GROUNDING INSTRUCTIONS
This appliance is equipped with a cord having a grounding wire with a
grounding plug which must be plugged into an outlet that is properly installed
and grounded. In the event of an electrical short circuit, grounding reduces
the risk of electric shock by providing an escape wire for the electric current.
WARNING—Improper use of the grounding can result in a risk of elec-
tric shock. Consult a qualified electrician or serviceman if the grounding
instructions are not completely understood, or if doubt exists as to whether
the appliance is properly grounded.
The ground lug of this appliance must be connected to a suitable building
ground.
IMPORTANT:
Power cord is 6' long.
If necessary, contact a licensed
electrician to install an appropriate
20 amp electrical circuit with correct
NEMA receptacle. DO NOT use an
extension cord.
WARNING:
Risk of personal injury
Installation procedures must be
performed by a qualified technician
with full knowledge of all applicable
electrical codes.
Failure can result in personal injury
and property damage.
IMPORTANT:
NOT UNDER WARRANTY
Damage to unit due to be-
ing connected to the wrong voltage
or phase is NOT covered by war-
ranty.
CAUTION:
Risk of personal injury
Unit is not waterproof, to
avoid electrical shock keep unit and
counter from being submerged in
water. Do not operate if unit has
been submerged in water.
CAUTION:
Electrical Shock Hazard
The ground prong of the
power cord is part of a system de-
signed to protect you from electric
shock in the event of internal dam-
age.DO NOT cut off the large round
ground prong or twist a blade to fit
an existing receptacle.
CAUTION:
To reduce the risk of fire,
the appliance is to be
mounted on surfaces of noncom-
bustible material only.

Purpose Frequency Cleaning Agent Method of Application
Routine Daily Soap, ammonia Sponge with cloth, rinse with clear water
cleaning detergent and water and wipe dry.
Smears/ As Stainless steel cleaner Rub with soft cloth as directed on package.
Fingerprints needed or similar products Rub in direction of grain of stainless steel.
Do not use on vinyl trim.
Stubborn Daily Any chloride-free Apply with damp sponge or cloth. Rub in
spots and as or direction of grain of stainless steel. Rinse
stains needed phosphate-free thoroughly, especially if cleaner contains
cleaner chlorine bleach, do not use on vinyl trim.
Hard water Daily Vinegar Swab with cloth.

CAUTION:
ELECTRIC SHOCK
HAZARD
Disconnect appliance from
electric power before cleaning.
CAUTION:
HOT SURFACE
Exposed surfaces can be hot
to the touch and may cause
burns. Allow appliance to cool
before cleaning.
IMPORTANT: DO NOT spill
or pour water into controls,
control panel or wiring. Water
damage is not covered by
warranty.
CAUTION:
Beware of sharp
edges on sheet
metal during cleaning,
especially during removal
of grease filters.
Cleansers, detergents, degreasers, sanitizers, or bleaching agents that contain chlorides or phos-
phates will cause permanent damage to stainless steel products. The damage appears as pits,
eruptions, voids, small holes, severe discoloration or dulling of the metal finish. Water with
