responsibility for its safe transit and delivery. If damaged equipment is received, either apparent or concealed, a claim
must be made with the delivering carrier.
Apparent damage or loss must be noted on the freight bill at the time of delivery. The freight bill must then be signed
by the carrier representative (Driver). If the bill is not signed, the carrier may refuse the claim. The carrier can supply
the necessary forms.
A request for inspection must be made to the carrier within 15 days if there is concealed damage or loss that is not
apparent until after the equipment is uncrated. The carrier should arrange an inspection. Be certain to hold all contents
plus all packing material.
1. Cut banding straps and remove packing material.
2. Cut banding strap holding oven to wooden skid.
3. If you are installing a single-deck oven, go to Step 2a.
If you are installing a double-deck oven, go to Step 2b.

oven.
1. Uncrate the two ovens. Identify the oven that will be the lower oven (it will be the oven with leg pads attached to the
bottom corners). Attach the legs (or casters) to the lower oven as described in Step 3 on page 11.

Each oven will have one of the three types of control panels:
• Models with Standard Controls are the most similar to a standard (non-convection) oven. Instructions for operating

as programming recipes and cooking groups. Instructions for operating this type of oven begin on page 25.
MOISTURE VENT
Each oven has a moisture vent that is opened and closed using the small knob located near the top left corner of the front
panel of the oven (see illustration below). Usually the vent is kept open to allow moisture to escape. Close the vent (turn
