Align the inner flanges with the inside of the universal brackets. Fasten with one (1) screw each into the end hole of the universal bracket.
Tighten screws securely but do not overtighten.
6. Place the steam convection oven unit on top of the universal connector brackets and fasten in place using two (2) screws per side. Tighten the screws securely, but do not overtighten.
Note: The existing screws in the steam convection oven base help with alignment. When lowering the steam convection oven into place on the universal connector brackets, allow these screw heads to slide into the slots as shown in the illustration below. The screw nearest the front of the steam convection oven should slide into the base of the slope at the front of the bracket.
7. Continue to “Connecting the Speed Oven or Steam Convection Oven Electrical Conduit to the Lower Oven”.
Note: When installing the combination unit, the speed oven or steam convection oven, the power cable must be properly attached to the oven-mounted junction box. This must be done prior to supplying electrical power to the oven unit.
WARNING: Check to be sure that no electrical power has yet been supplied to the oven.
1. Remove the oven-mounted junction box cover located on the top rear of the oven. (See image below).
2. Remove the cap from the conduit access hole in the side of the oven-mounted junction box.
3. Guide the wires from the conduit cable (coming from the speed oven or steam convection oven through the hole in the oven-mounted junction box. (See image below). There are four wires from a speed oven or three wires from a steam convection oven--no white wire from a steam convection oven.
4. Snap the conduit connector into the hole by pressing it in until it clicks into place.
5. Follow the wiring diagram label (see image below) and match and connect each wire by color to the wires attached to the wiring block inside the oven-mounted junction box. Push the bare end of the wire until it is snug in the wiring block then tighten down the retaining screw on each wire.
Tighten securely, but do not overtighten.
