SECTION 1 - GENERAL DESCRIPTION.
The E4069EL andE4109EL are combination
atmospheric convection steam ovens. These units
may be used in three different modes:
Convection Mode
These units operate as normal forcedconvection
ovens. The fan draws air from the oven which is
passedover the elements surround
ing the fan.
The air is then recirculatedback into the oven around
the sides of the oven baffle.
Steam Mode
The units operate as forcedair steaming ovens.
Steam generatedby the boiler is circulatedaround
the oven by the fan.
For economic water usage, set the temperature
selector switch between 95
o
C and100
o
C on steam
mode. Setting the selector switch above 100
o
C will
not allow the boiler to switch On/Off with temperature
modulation thus greatly increasing water usage.
A temerature greater than 100
o
C cannot be achieved
in steam mode.
The oven temperature may also be controlled
between 30-100
o
C in this mode by controlling the
amount of steam injectedinto the oven cavity.
Combination Mode
This combines the benefits of steam andconvection
cooking. Oven is suppliedalternately with hot air and
steam. The benefit of low weight loss on steam is
combinedwith the benefits of convection cooking.
Hot air andsteam are circulatedat high speedto
provide even cooking.
SECTION 2 - CONTROLS and OPERATION.
CONTROLS.
CONTROLS.
The controls are mountedon a panel at the Oven RH
as detailed in Figure 1. These consist of:
Power On Indicator (Red)
This Indicates there is power to the unit.
Heat/Cool Switch
This control in Redposition allows the fan to operate
normally for cooking modes.
This control in Black position allows the fan to operate
when door is open and activates cool down facility.
On/Off Temperature selector switch
When knob is turnedfully anticlockwise, power to
oven controls is switchedoff.
When knob is turnedclockwise, power is fedto the
controls. The knob is then rotatedclockwise to select
the desired cooking temperature.
Oven On Indicator (Amber)
This Illuminates when oven elements are on in either
convection or combination cooking cycle.
