5. INSTALLATION CONT’D
5.2 Stacking the Ovens
Remove all the plug buttons from the top of the lower oven.
Remove the stacking kit from the oven compartment of one oven and install the 1 1/4
inch plastic bushing into the top of the lower oven.
Tip the top oven backwards and install two 3/8 inch socket head bolts, found in the
stacking kit, into the two front leg holes that match the holes in the top of the lower
oven. Install the socket head bolts with the heads of the bolt pointing away from the
oven.
Lift the top oven and gently set on top of the lower oven so that the heads of the
socket head bolts nest into the holes in the top of the lower oven.
5.3 Electrical Connection
The electrical service entrance is provided by a 1 1/4 inch knockout in the bottom
right front corner of each oven, or at the oven back directly behind the control
compartment. Grounding lugs are provided at both the front and rear service
entrances.
The 208/240 volt oven is a dual voltage oven and is shipped from the factory as 208
volt. The oven must be field converted to operate on a 240 volt power supply.
To convert the oven to 240 volt, remove the jumper wire located on a terminal strip
located inside the lower portion to the control compartment.
With 480 volt installations check to be sure that the motor rotates in a clockwise
direction as viewed from the front of the oven.
To reverse the motor rotation, switch any two incoming power supply leads and
recheck the rotation.
Supply wire size must be large enough to carry the amperage load for the number of
ovens being installed. Wire size information can be found on the oven DATA
PLATE.
This oven can be installed on both single and three phase supplies and is shipped
from the factory for three phase.
To phase the oven to match the power supply, follow the charts on page 10 for proper
wire size and grouping.
