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, temporarily slowing the cooling of product 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.

INSTALLATION
Location
For proper operation and maximum performance, locate the Crisp n’ Hold in an
ambient 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.
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 ersonal 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.
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.
Countertop Mounting
NOTE: CNH12LP, CNH18LP and CNH28LP drop-in models are not intended 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. CNH28LP: 27.125”D x 27.125”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 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.
STARTUP AND NORMAL OPERATION
CAUTION: HOT SURFACE
Inner surfaces of the unit will be very hot during and after operation.

Daily operating procedures
- Prior to use, unit must have been installed properly and tested by a trained installation or service professional.
- Unit must be clean and grease free prior to use.
- Verify that the grease pan, heat duct and air filters are installed properly.
- Turn power on by flipping the rocker switch upwards , which should be lit to indicate there is power to unit. The motors should begin to turn and create airflow.
- Unit will automatically begin to preheat, allow 10-15 minutes for unit to climb to operating temperature of 160º degrees F.
- Load product into Crisp n’ Hold.
- The cabinet must be cleaned daily. Perform cleaning at the end of each day. It is important to follow the cleaning procedures to keep grease and debris from building up. Failure to perform daily cleaning will clog the filters and damage the electrical compo- nents. See page 7 for cleaning instructions.
CLEANING PROCEDURES
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.
