Water Connection
All water connections must comply with the basic plumbing code of the Building Officials
and Code Service Sanitation Manual of the Food and Drug Administration (FDA)
WATER PRESSURES GREATER THEN RECOMMENDED CAN CAUSE EXCESS
WATER TO ENTER THE OVEN CAUSING WATER TO LEAK AT THE DOOR AND
ALSO CAUSE THE TEMPERATURE TO DROP SEVERELY AFFECTING THE BAKE.
USE A PRESSURE REGULATOR TO REGULATE THE PRESSURE.
The oven must be connected to a water supply to enable the oven to produce steam for
baking. As shipped from the factory the oven will have a solenoid valve at the back
center of the oven, (See figure 3.0 page 2-2). This valve has an internal 1/4" NPT thread
for connection. Water pressure should be a maximum of 60 to 70 PSI and the water
must clean. Use a pressure regulator and a water strainer/filter to meet these
guidelines. Before making the water connection flush all lines and install the regulator
and filter. Remember solenoid failure and related problems caused by dirt may not be
covered by your warranty.
HARD WATER LEAVES MINERAL DEPOSITS ON GLASS AND OTHER SURFACES
WHICH DETRACT FROM OVEN APPEARANCE.
The solenoid valve can be checked after "Set Up" and the "Electrical and Water
Connection" has been completed. At the lower right hand corner of the front surface of
the oven you will find a small rectangular panel held in place with two thumb screws.
Removing these screws and the panel they secure will expose the "Manual" controls of
the oven. Use the following sequence to start the oven to check solenoid operation.
•
Switch the oven to manual mode.
•
Turn the main power switch on, (green button above the manual controls).
•
Press the steam button briefly and release, water should spray from each of the
spray nozzles. Adjust the spray nozzles if required so that they are vertical and
spray directly into the fans.
•
Once complete, turn the main power switch off, (red button above the manual
controls), return the oven to automatic mode and replace the cover.
Venting
On the rear side of the oven near the top is a 3" diameter exhaust vent protruding
approximately 3/4" from the oven. Vent the exhaust (hot air and steam) to the outside by
connecting to this vent.
