Page 10 Installation PLATINUM SERIES HALF-SIZE ELECTRIC CONVECTION OVENS Step 2b: Installation of 26” Legs on Single-Deck Models 1. Raise the oven sufficiently to allow clearance for the legs to be attached. Use of a lift truck or other mechanical lifting means is recommended. For safety, “shore up” and support the oven with an adequate blocking arrangement strong enough to support the load.
Page 11 PLATINUM SERIES HALF-SIZE ELECTRIC CONVECTION OVENS Installation Step 2c: Installation of Legs or Casters on Double-Deck Models Double-deck ovens can be shipped either already bolted together, or as two separate ovens to be bolted together after delivery. In either case, the oven that is (or will be) the lower oven will have leg pads already bolted to the bottom corners of the oven.
Page 12 Installation PLATINUM SERIES HALF-SIZE ELECTRIC CONVECTION OVENS Step 3: Installation of Restraint (Only for Ovens with Casters) NOTICE For an appliance equipped with casters, (1) the installation shall be made with a connector that complies with the Standard for Connectors for Movable Appliances, (2) adequate means must be provided to limit the movement of the appliance without depending on the connector and the quick-disconnect device or its associated piping to limit the appliance movement and (3) the restraining means should be attached to a frame member on the back of the unit.
Page 13 PLATINUM SERIES HALF-SIZE ELECTRIC CONVECTION OVENS Installation 2. Install eye-bolt (item “F”) to a frame member on the rear of the equipment. After checking carefully behind the frame member for adequate clearance, drill a 1/4” hole through the frame member. 3.

Cooking Hints PLATINUM SERIES HALF-SIZE ELECTRIC CONVECTION OVENS Cooking Hints In a standard (non-convection) oven, the air is relatively still and an insulating layer of moisture surrounds the cooking food product. In a convection oven, the fan-blown circulating air strips away this insulating layer allowing the heat to penetrate faster for quicker baking and roasting.
