Installation, Operation and Care of
ELECTRIC CONVECTION OVENS
KEEP THESE INSTRUCTIONS FOR FUTURE USE
Your Electric Convection Oven is produced with quality workmanship and material. Proper installation,
usage and maintenance of your oven will result in many years of satisfactory performance.
The manufacturer suggests that you thoroughly read this entire manual and carefully follow all of the
instructions provided.
GENERAL
The Electric Convection Ovens feature a 500°F thermostat, timer, porcelain interior and a two -speed, 1/2
HP blower motor as standard equipment. Ovens equipped with standard voltages are 208 or 240 V, 60 Hz,
single- or three-phase. Ovens equipped for 480 V, 60 Hz, single- or three-phase electrical speciflcations
are optional.
The Oven is a single cavity oven furnished with flve racks. Independently opening doors are standard;
simultaneously opening doors with chain mechanism underneath are optional. Oven lights with on-off
switch are standard on all models.
An open stand with lower storage rack is available as an option.
Stacked ovens are furnished with either Stacking Kit 426983G1 (8" LEGS) or Stacking Kit 426984G1
(CASTER) for mounting one oven on top of the other.
Additional racks are available as accessories.
Features of the models are shown below:

INSTALLATION
UNPACKING
Immediately after unpacking the oven, check for possible shipping damage. If the oven is found to be
damaged, save the packaging material and contact the carrier within 15 days of delivery.
Prior to installation, verify that the electrical service agrees with the speciflcations on the oven data plate,
located on the inside of the top front cover.
Do not use the doors or their handles to lift the oven.
LOCATION
The installation location must allow adequate clearances for servicing and proper operation. For solid
state and digitally controlled models, there must be 18" (45 cm) of clearance on the right side of the oven
from any open ‡ame.
INSTALLATION CODES AND STANDARDS
In the United States, install the oven in accordance with: 1) State and local codes; 2) National Electrical
Code, NFPA-70 (latest edition) and 3) NFPA Standard #96, Vapor Removal from Cooking Equipment
(latest edition), available from National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
In Canada, install the oven in accordance with: 1) Local codes; 2) Canadian Electrical Code, CSA
Standard C22.2 No. 1 (latest edition) and 3) Canadian Standard for Commercial Cooking Equipment CSA
Standard C22.2 No.109 (latest edition).
INSTALLING BASIC OVEN
The basic oven must be installed on legs or mounted on a modular stand. Installations on concrete bases
or other supports restricting air circulation underneath the oven is not advisable and may void the warranty.
If using the modular stand, set the oven on the stand after unpacking.
ASSEMBLING THE LEGS TO THE SINGLE OVEN
The legs must be installed on the bottom of the oven. Gently position the oven on its left side, taking care
not to cause scratches or damage.
Attach each of the four leg assemblies to the bottom of the oven with the 24 bolts and lockwashers
(six bolts and lockwashers per leg). Carefully raise the oven to its normal position.
LEVELING
Adjust the legs to ensure that the oven racks are level in the flnal installed position.
CASTERS
If the oven is to be installed on casters, assemble the casters to the legs provided. Then attach the caster-
leg units to the oven at each corner using the 24 bolts and lockwashers (six bolts and lockwashers per
leg). Place the locking casters on the front legs and nonlocking casters on the rear legs.

– 5 –
ASSEMBLING THE STAND TO THE OVEN
Attach each of the four leg assemblies to the bottom of the
oven with the 24 bolts and lockwashers (six per leg). Carefully
raise the oven to the normal position.
Attach the undershelf to the legs with eight bolts and
lockwashers (two per leg).
Install the rack guides into the shelf at the desired locations
(for pan or ‡at rack), then attach the rack supports to the
top end of the rack guides. Attach rack supports to the leg
assembly by removing one middle bolt and reattaching the
back through the end holes in the rack support (Fig. 2).
