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 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.
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.
INSTALLATION
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 meets the counter top with a food grade ilicone 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. Avoid
touching the cabinet when loading or removing product.
Startup
- Plug the Crisp n’ Hold into a properly grounded electrical receptacle.
- Ensure all plastic and packaging materials have been removed.
- Set POWER switch to “ON” position.
- Do not load product into the cabinet. Allow the heat to remove any residual oils which may adhere to inside metal surfaces.A slight emission of smoke is normal for the first few hours of operation.
- Cabinet is preset at the factory, no temperature adjustment is necessary.
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 components. See page 7 for cleaning instructions.
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.
CLEANING PROCEDURES
- After all food products have been removed from the cabinet, turn the power switch to “OFF” and allow the cabinet to cool.

- Remove and clean the grease / crumb pan from the bottom of the unit by sliding it out towards the operators side of the unit. Clean the pan as well as pan housing.
- The air filter can be easily removed without tools for cleaning by lifting up and pulling towards the front of the unit. Clean by hand washing or run through an automatic washer. Reinstall when filter is dry and clean.
- Remove the product bottom heat duct and divider assemblies. Clean the inside of the unit as well as the removed parts. Reinstall when all parts are dry and clean.
- Inspect and clean the areas where there are vents, making sure no water gets into the internal controls or electrical areas of the cabinet.
Cleansers, detergents, degreasers, sanitizers, or bleaching agents that
contain chlorides or phosphates 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 high chloride content
can also damage stainless steel.
If unsure of your water quality, we recommend you have it tested. THIS DAMAGE
IS PERMANENT, COSTLY TO REPAIR, AND IS NOT COVERED BY THE WARRANTY
