FEATURES & SPECIFICATIONS
Forced Convection Food Holding Cabinet
The Crisp n’ Hold provides a heated stream of air to maintain crispy or fried food temperature and freshness for a
specified period of time after cooking. Forced air is heated through an electric resistance heater and ducted into
cabinet interior. The heated air is discharged through small circular openings in the bottom and sides of the cabi-
net interior caddy, which is removable. A plenum on the front of the cabinet aids in directing a warm blanket of
air over the food. Pans rest on wire rods built into the cabinet.

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 unplugged from an
electrical outlet. If unit has been operated, allow unit to cool
before installing.
INSTALLATION & START-UP
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.
IMPORTANT:
Power cord is 10' long.
If necessary, contact a licensed
electrician to install an appropriate
electrical circuit with correct NEMA
receptacle. See serial tag on cabi-
net for electrical specifications.
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:
Risk of personal injury
Unit is not waterproof, to avoid
electrical shock keep unit and coun-
ter from being submerged in water.
Do not operate if unit has been sub-
merged in water.
CAUTION:
Electrical Shock Hazard
The ground prong of the power cord
is part of a system designed to pro-
tect 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.
Start-up
1. Plug the Crisp n’ Hold into a properly grounded electrical
receptacle.
2. Ensure all plastic and packaging materials have been
removed.
3. Set POWER switch to “ON” position.
4. Do not load product into the cabinet. Allow the heat to
remove any residual oils which may adhere to inside met-
al surfaces. A slight emission of smoke is normal for the
first few hours of operation.
5. Appliance is preset at the factory. However, the tempera-
ture is adjustable. See pages 7-10 for programming in-
structions.
IMPORTANT:
Not under warranty:
Damage to unit due to being
connected to the wrong voltage or
phase is NOT covered by warranty.
To prevent an electrical shock hazard between the
appliance and other appliances or metal parts in close
vicinity, an equalization-bonding stud is provided. An
equalization bonding lead must be connected to this
stud and the other appliances/metal parts to provide
sufficient protection against potential difference. The
terminal is marked with the following symbol:
