B. CABINET START-UP

1. a nine-foot, three-wire grounded lead cord is
supplied fixed to the cabinet. the cord cannot
be separated from the cabinet.

NOTE: Before operating your cabinet be sure to
unwrap the lead cord completely from bracket.

CAUTION: With the POWER switch OFF, plug
the lead cord into a standard grounded 15-amp,
125-VAC receptacle.

2. Set the thermostat dial to setting 10 = HigH.

3. Snap the PoWeR switch to on. the red
PoWeR light will now glow as will the yellow
indicator light indicating that power is on and
that the heating elements are activated and
heating up.

4. allow the cabinet to PReHeat FoR
aPPRoXiMateLY 45 MinUteS. after that time,
the thermostat can be lowered to a setting of
6 or 7. in a room of average temperature
(72�F), this should provide 150�F to 170�F.
adjustments to the temperature may be made
as necessary.

NOTE: The POWER (red) light will glow as
soon as the POWER switch is switched ON
and will continue to glow until switched OFF.
The yellow indicator light will go on and off as
the thermostat cycles. If the yellow light is not
illuminated, this indicates that the cabinet has
achieved the preset TEMPERATURE level,
NOT that the unit has been switched OFF.

it is not necessary at the end of the operating
day to disrupt the temperature setting in order
to turn the unit oFF. By switching the PoWeR
switch to oFF, the unit is no longer operating.

By switching the PoWeR switch to on when
resuming operations, the cabinet will attain the
preset level. 3
