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 final 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.

HOLDING

PROPER UTENSILS

The use of proper utensils can enhance oven operation. Medium and lightweight pans allow the product
to warm faster. Roast meats in shallow pans deep enough to hold all juices yet allow free air circulation.

OPERATING HINTS

When using the convection oven for the first time with a particular food, check the degree of doneness
periodically before the suggested time has elapsed. This will ensure the desired doneness is achieved.

Record your temperature and time settings for various products. The convection oven can provide
consistent and repeatable results.

The convection oven is faster than conventional deck-type ovens; temperature settings are lower and
cook times are shorter. Since recipes and foods are subject to many variations and tastes, the
guidelines regarding Times and Temperatures in this manual are SUGGESTIONS ONLY. Experiment
with your food products to determine the cooking temperatures and times that give you the best results.

NOTE: For a more even bake in models HEC5X and HEC5DX, place the pans horizontally in the center
of the oven rack and decrease the suggested cooking temperature by 50°F (10°C).

POWER OUTAGE

In case of a power outage, the oven will automatically shut down. When power is restored to the lines,
the oven will resume its normal operation. However, if the oven is to be left unattended during a power
outage, push the POWER switch to the OFF position. When power is restored to the lines, push
POWER switch to the ON position, wait for the oven to preheat, then resume normal cooking
operations.

CLEANING

WARNING: DISCONNECT ELECTRICAL SUPPLY AND PLACE A TAG AT THE DISCONNECT

SWITCH TO INDICATING THAT YOU ARE WORKING ON THE OVEN BEFORE CLEANING.

• Clean outside of the oven daily by wiping with a clean, damp cloth.

• Clean porcelain oven interior daily with soap or detergent and water. Rinse thoroughly and

wipe dry with a soft, clean cloth.

Optional Stainless Steel Oven Interior

Soap or detergent and water usually handle routine cleaning. Rinse thoroughly and dry with a soft,
clean cloth.

For burned-on foods and grease which resist simple soap and water cleaning, an abrasive cleanser
(scouring powder) mixed into a paste may be used. Apply with stainless steel wool or sponge, always
rubbing with the grain.

This treatment is equally effective for "heat tint" (slightly darkened areas caused by oxidation). Again,
remember to rub in the direction of the polish lines. Rinse with clear water and dry with a soft cloth.
