GENERAL OPERATING INSTRUCTIONS
1) PLUG CABINET INTO OUTLET making sure it is a properly
grounded power receptacle. Press ON-OFF rocker switch to "ON"
position. The indicating light on the switch will come on and remain
"ON" until the rocker switch is turned to "OFF" position.
2) ADD HOT WATER TO THE
12" x 20" PAN. The 12" x 20"
WATER PAN is positioned in the
HEAT BASIN. Do NOT allow
any water into the HEAT BASIN.
Add HOT water into the 12" x 20"
pan prior to heating the cabinet.
This will allow the heating system
to condition cabinet and add
humidity.
It is not necessary to remove the
pan to add water. Amount of water
required depends on start-up time,
length of proofing, and level of
humidity desired.
3) PRE-HEAT THE CABINET by turning the rocker switch to
the "ON" position. Allow approximately 15-25 minutes of pre-heat time.
The door should be kept tightly closed during this procedure to obtain
the optimum environment.
For proofing, set the air temperature to 100°F or 38°C
4) SET AIR MOISTURE CONTROL to desired setting.
The "MOISTURE" indicator light will illuminate,
and remain on for the duration of the cycle.
NOTE: As with all proofing cabinets, your results may vary, depending
on room temperature and conditions, pre-heat time, temperature of
product going into cabinet, etc.
5) LOAD THE CABINET with your product as quickly as possible.
To maintain the best conditions, the door should be tightly closed
when not loading the cabinet, and remain closed until serving.
