EQUIPMENT SET-UP AND
CLOSE PROCEDURES
The Introduction and Installation sections of
this manual should be read before operating
the cabinet.
This section contains an explanation of all
controls and components and information
on operating procedures and daily mainte-
nance.
Heated air inside the cabinet is circulated
over 2 heating coils and across a water pan.
The warm, moist air is then forced down-
ward through air ducts on each side of the
unit. The heated air is dispersed over and
under the product from openings in the air
ducts. These openings are varied in size to
promote uniformity of heated air throughout
the cabinet.
Set-up
Place the power switch in the ON position.
If humidity is desired, remove the water pan
and put approximately 1" of hot water in the
pan. Then return the pan to the unit.
NOTE: Be sure to push the water pan in
as far as it will go so that it does not
block air from the temperature probe.
This will assure proper operation of the
controls.
The display will increase in temperature,
indicating the cabinet is heating. When the
operating preset temperature is reached the
"HEAT ON" LED will turn off and the display
should stay at the preset temperature.
Once the preset temperature shows on the
display, product can then be placed in the
cabinet. Slide a tray of product into the
racks, close the door, and press the appro-
priate timer button on the controls.

Vent Adjustment

The vent setting corresponds to the number of
trays of product. With one tray of product, set
the vent at No. 1. With two trays of product, set
the vent at No. 2, and so on.
