The oven must be mounted on the factory equipped
oven legs or on an optional oven stand. Installation
on a solid or concrete base that in any way restricts
air flow may void the warranty.
All clearances for a proper ventilation air supply
must be maintained to minimize fire hazard. Do
not locate the oven immediately adjacent to any
other heat-generating appliance.
A number of adjustments are associated with initial
installation and start-up. Adjustments must be
conducted by a qualified service technician.
Installation and start-up adjustments are the
responsibility of the dealer or user. These
adjustments include but are not limited to
thermostat calibration, door adjustment, leveling,
and gas pressure verification. The Platinum series
oven burners are factory-adjusted with fixed air
openings and require no field adjustment.
LEVELING
The oven should be leveled before the gas
supply is connected. Level the oven from side-to-
side and front-to-back with the use of a spirit level.
For ovens installed on a mobile stand, it is
important that the floor surface be level due to the
probability of frequent oven repositioning.
We recommend checking the level of the oven
periodically to make certain the floor has not
shifted nor the oven moved.
I N S T A L L A T I O N R E Q U I R E M E N T S
W A R N I N G
Inadequate ventilation, or failure to
ensure an adequate supply of fresh
air will result in a high ambient
temperature at the rear of the
appliance. An excessive ambient
temperature can cause the thermal-
overload protection device on the
blower motor to trip resulting in severe
damage to the blower motor.
C A U T I O N
TO PREVENT PERSONAL INJURY,
USE CAUTION WHEN MOVING OR
LEVELING THIS APPLIANCE.

possible to retain maximum oven compartment heat.
5. Set COO TIMER by rotating the knob
clockwise past the time required and then back to
the desired time.
The timer will begin to count down. When the

he Alto-Shaam convection oven will provide the best results and longest possible
service with the utilization of the following suggestions and guidelines.
NOTE: Moisture will escape around the doors when baking products with a heavy
moisture content such as chicken, potatoes, etc. his is a normal operating condition.
Do not place anything directly
on the bottom of the oven cavity.

1. horoughly preheat the oven for approximately
20 minutes before use.
2. As a general rule, the cooking temperature can
be set lower than the temperature used in a
conventional oven. Cooking time may also be
shorter. It is suggested the first batch of each
product prepared be monitored closely to check
for variances.
3. Maintain a record of the temperatures, times, and
load capacities established for products cooked on a
regular basis since they will be the same or similar
for succeeding loads.
4. When practical, start cooking the lowest temperature
products first and gradually work up to products
with a higher cooking temperature.
5. If the cooking temperature setting for the previous
product is more than 10°F (5°C to 6°C) higher
than the temperature needed for the next load,
use the FAN COOL-DOWN feature to decrease
the oven temperature before setting the oven to a
lower temperature.
6. Work as quickly as possible when loading the
oven to prevent heat loss.
7. When the audible signal indicates the time has
expired, remove the food product from the oven
as quickly as possible to avoid over cooking.
8. Pans should be centered between side racks and each
shelf should be loaded evenly to allow proper air
circulation within the oven compartment.
9. o assure even cooking when baking, weigh or
measure the product in each pan.
10. ASC-2E: When cooking five pans of product, start
from the bottom of the oven and use side rack
positions 1, 3, 5, 7, and 9.
ASC-4E: When cooking six pans of product, start
from the bottom of the oven and use side rack
positions 2, 4, 6, 8, 10, and 12.
11. Do not overload the oven. Refer to product/pan
capacties indicated in this manual.
12. o obtain an evenly baked product, muffin pans
should be placed in the oven with the short side of
each pan facing the front of the oven.
13. When rethermalizing frozen casseroles, preheat the
oven 100°F (38°C) over the suggested temperature to
compensate for the introduction of a large quantity of
frozen product into the oven compartment. Reset the
thermostat to the correct cooking temperature after
the oven is loaded.
14. Use a pan extender or two inch (51mm) deep,
18” x 26” pans for batter-type products that weigh
more than 8 pounds (3 to 4 kg), i.e.; pineapple
upside-down cake.
15. o avoid obstructing airflow that would result in
uneven cooking, never place anything directly on the
bottom of the oven cavity.

PROTECTING STAINLESS STEEL SURFACES
It is imp rtant t guard against
c rr si n in the care f
stainless steel surfaces.
Harsh, c rr sive, r
inappr priate chemicals can
c mpletely destr y the
pr tective surface layer f stainless steel.
Abrasive pads, steel w l, r metal implements
will abrade surfaces causing damage t this
pr tective c ating and will eventually result in
areas f c rr si n. Even water, particularly hard
water that c ntains high t m derate
c ncentrati ns f chl ride, will cause xidati n
and pitting that result in rust and c rr si n. In
additi n, many acidic f ds spilled and left t
remain n metal surfaces are c ntributing fact rs
that will c rr de surfaces.
Pr per cleaning agents, materials, and
meth ds are vital t maintaining the appearance
and life f this appliance. Spilled f ds sh uld be
rem ved and the area wiped as s n as p ssible
but at the very least, a minimum f nce a day.
Always th r ughly rinse surfaces after using a
cleaning agent and wipe standing water as quickly
as p ssible after rinsing.
CLEANING AGENTS
Use n n-abrasive cleaning pr ducts designed f r
use n stainless steel surfaces. Cleaning agents
must be chl ride-free c mp unds and must n t
c ntain quaternary salts. Never use hydr chl ric
acid (muriatic acid) n stainless steel surfaces.
Always use the pr per cleaning agent at the
manufacturer's rec mmended strength.

CLEANING MATERIALS
The cleaning functi n can usually be acc mplished
with the pr per cleaning agent and a s ft, clean

empl yed, use a n n-abrasive sc uring pad n
difficult areas and make certain t scrub with the

1. After the oven has cooled, remove all detachable
items such as wire shelves, side racks, and drip
pan. Clean these items separately.
2. Remove any food scraps from shelves, shelf
supports, and blower fan wheel. Convection
baffle openings must be kept clear of food
scraps and grease.
3. Wipe the interior metal surfaces of the oven
with a paper towel to remove any remaining
food debris.
4. Clean interior with a damp cloth or sponge
and any good commercial detergent at the
recommended strength.
5. For baked-on food deposits, use a non-caustic
and non-toxic commercial oven cleaner
appropriate for the interior oven surface of
your oven. Follow the product manufacturer's
instructions carefully for the use of this
product. Any commercial oven cleaner
must be approved for use on food contact
areas. Remove soil with the use of a plastic
scouring pad.
6. Wipe door gaskets
thoroughly since these areas
harbor food debris and grease.
7. Rinse surfaces by wiping with a
clean cloth or sponge and clean
warm water.
8. Remove excess water with a sponge and wipe
dry with a clean cloth or air dry. Leave doors
open until interior is completely dry. Replace
side racks and shelves.
Always follow appropriate state or local health
(hygiene) regulations regarding all applicable
cleaning and sanitation requirements for food
service equipment.
The oven is fabricated with an easy to clean porcelain
enamel interior or an optional stainless steel interior.
NOTE Always allow the oven to cool before
cleaning. If the oven is hot, allow the
interior surfaces to become cool to the
touch by opening the oven doors and
engaging the cool-down function.
DO NOT USE ABRASIVE CLEANING COMPOUNDS.
Completely avoid the use of abrasive cleaning
compounds, chloride-based cleaners, or cleaners
containing quaternary salts. To protect metal
finish on stainless steel, never use hydrochloric
acid (muriatic acid).

To help maintain the protective film coating on
polished stainless steel, clean the exterior of the
cabinet with a cleaner recommended for stainless
steel surfaces. Spray the cleaning agent on a clean
cloth and wipe with the grain of the stainless steel.
Wipe control panel, door vents and door handles,
thoroughly since these areas harbor food debris.
Clean exterior glass surfaces with a commercial
window cleaner.
DO NOT USE ABRASIVE CLEANING COMPOUNDS.
MO T O R C A R E
The convection oven motor contains self-
lubricating, sealed ball bearings and is
generally maintenance-free. During operation,
the interior of the motor is cooled by air flowing
into the rear of the motor case. This is a general
operating feature when proper clearances have
been allowed.
