General Operation & Programming
Convection ovens constantly circulate air over and around the product. This strips away the thin layer of moisture
and cool air from around the product allowing heat to penetrate more quickly.
Cooking times can be shortened and cooking temperatures can be reduced.
To convert standard deck oven recipes, reduce the temperatrue 50° degrees and the time by 25%. Make minor
adjustments as necessary.
Always weigh your product. This will give you a more consistent size, color and quality.
Check the product near the end of the initial cooking.
Do not open the oven door during baking, as this will change the baking characteristics of the oven and make it
difficult to determine a final program.
If the product is overdone on the outside and underdone on the inside, reduce the baking temperature.
If the product is pulling away from the edge of the pan, the temperature is too high or the cooking time too long.
A convection oven is a mechanical piece of equip-
ment. The same control settings will always give the
same results.
If the results vary, problems may be because of
changes in the product preparation.
ECOH-AP Control Panel
The Control panel consists of the following items.
Detailed operational descriptions are given later this
section.
Power Switch: Turns the oven on and off
Pulse Fan Switch:
Pulse Setting: Fan will only turn ON, when the
oven is calling for heat.
Fan Setting: Fan is on continuously, speed is
determined by the Hi/Low switch.
Hi/Low Speed Fan Switch: Dual speed switch.
Toggles the fan between high & low speed.
Temperature Control: Allows temperature to be set
in 25°F increments from 140°F to 450°F
Timer: Electronic on-hour timer with
continuous beeper,
