FREIGHT DAMAGE PROCEDURE

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 service agent if the grounding instructions are not completely understood, or if doubt exists as to
whether the appliance is properly grounded.

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.

WARNING:

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 in contact with water.

LOCATION

For proper operation and maximum performance, locate the unit
in an ambient air temperature of 70ºF (21ºC).

Avoid placement in areas near exhaust fans or where there are
active air movements.

For safe operation and maximum performance, locate the unit at
least 2” from any wall or combustible material.

Unit must be on a solid level surface.

STARTUP

1. Prior to use, thoroughly clean the interior of the unit and the
water reservoir, per the instructions in this manual.

2. Install water trough at base of door. Keyhole cutouts will fit
over bolts at base of door. Slide trough until the ends are
flush with the edges of the door.

Keyhole cutouts—fit over shoulder bolts located at the base of the door.

3. Install the universal pan slides in each tray rack located at
each side of the cabinet. Standard spacing is every other slot
(3” apart). Begin with the lowest slot at the bottom of the cab­inet and work your way up. Hold the slide at an angle and line
up the tabs at either end with the slots in the tray rack. Slide
the tabs into the slots, then tilt the slide down so that it is lev­el. If you have a cabinet with optional fixed angle slides, they
are already welded to the tray racks.

4. Install water reservoir by pull­ing out the metal frame at the
upper left front of the cabinet
interior in front of the ele­ment. Slide pan up and then
forward so that it hangs from
inside the metal frame; make
sure the element is inside the
pan. Push entire assembly
back into the cabinet.

5. Plug the power cord of the cabinet into a grounded outlet with
a minimum 20 Amp 120VAC, 60HZ, single phase electrical
service.

6. Set POWER switch to the “ON” position.

7. Set temperature dial to 190°F. Do not fill humidity pan. Set
humidity dial to off (line up white dot on dial with white hash
mark, located at top of dial on control panel)

8. 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 common during the first
few hours of operation.
