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 ro und embossments to
minimize hot metal contact with the food.

INSTALLATION

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.

If necessary, contact a licensed
electrician to install an appropriate
20 amp electrical circuit with correct
NEMA receptacle.

WARNING:

Risk of personal injury

IMPORTANT:

Power cord is 7' long.

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.

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.

Countertop Mounting

To prevent electrical shock, be sure unit is unplugged from an
electrical outlet. If unit has been operated, allow unit to cool
before installing.

Counter must be made of a non-combustible material, clean
and free of debris. Locate and drill four mounting holes in
counter top.

Remove 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
silicone sealant.

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.

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.
