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. Adjustable and removable food dividers.

Location
For proper operation and maximum performance, locate the Crisp n’ Hold in an a mbient air temperature 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 operated, allow to cool before installing.
INSTALLATION

INSTALLATION
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.
CAUTION:
To reduce the risk of fire,
the appliance is to be
mounted on surfaces of noncombustible material only.
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.
CAUTION:
Electrical Shock Hazard
The ground prong of the
power cord is part of a system designed to protect you from electric
shock in the event of internal damage.
DO NOT cut off the large round
ground prong or twist a blade to fit
an existing receptacle.
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 occupied 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. Verify cut-out dimensions of the counter
-top. CNH12LP: 20.75”D x 24.25”
W; CNH18LP: 20.75”D x 30.25” W.
24.25” or 30.25” W
Warmer is equipped with CarterLocks, 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 counter 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.
IMPORTANT:
NOT UNDER WARRANTY
Damage to unit due to being connected to the wrong voltage
or phase is NOT covered by warranty.
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.
IMPORTANT: NOT UNDER WARRANTY
Damage caused by leaks due to improper installation is NOT covered by warranty
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 electric 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.
