Safety Procedures and Precautions
• This appliance is intended to cook, hold, or process foods
for the purpose of human consumption. No other use for
this appliance is authorized and is therefore considered
dangerous. The appliance must not be used to cook food
containing flammable materials (such as food with alcohol).
Substances with a low flash point can ignite spontaneously
and cause a fire.
• This appliance is intended for use in commercial
establishments where all operators are familiar with
the purpose, limitations, and associated hazards of this
appliance. Operating instructions and safety alerts must
be read and understood by all operators and users. We
recommend regular training of your staff to avoid the risk of
accident or damage to the unit. Operators must also receive
regular safety instructions.
• Any troubleshooting guides, component views, and parts
lists included in this manual are for general reference
only and are intended for use by qualified and trained
technicians.
• This manual should be considered a permanent part of
this appliance. This manual and all supplied instructions,
diagrams, schematics, parts lists, notices, and labels must
remain with the appliance if the item is sold or moved to
another location.
NOTICE: For equipment delivered for use in
any location regulated by the following
directive: 2012/95/EC WEEE
DO NOT dispose of electrical or
electronic equipment with other
municipal waste.
DANGER
Indicates a hazardous situation that, if not avoided, will
result in death or serious injury.
NOTICE: Indicates information considered important,
but not hazard-related (e.g., messages
relating to property damage).
Knowledge of proper procedures is essential to the safe operation
of electrically and/or gas energized equipment. The following
signal words and symbols may be used throughout this manual.
WARNING
Indicates a hazardous situation that, if not avoided, could
result in death or serious injury.
CAUTION
Indicates a hazardous situation that, if not avoided, could
result in minor or moderate injury.

MN-35947 •Rev 22 •10/22 •Combitherm® CT PROformance™ and CT Classic Series Installation Manual •7
Safety Procedures and Precautions
• To prevent serious injury, death, or property damage,
your appliance should be inspected and serviced at
least every twelve (12) months by an authorized service
partner or trained technician.
• ONLY allow an authorized service partner or trained
technician to service or to repair your appliance.
Installation or repairs that are not performed by an
authorized service partner or trained technician, or
the use of non-factory authorized parts, will void the
warranty and relieve Alto-Shaam of all liability.
• When working on this appliance, observe precautions in
the literature, on tags, on labels attached to or shipped
with the appliance, and other safety precautions that
may apply.
• If the appliance is installed on casters, freedom of
movement of the appliance must be restricted so that
utility connections (including gas, water, and electricity)
cannot be damaged when the unit is moved. If the
appliance is moved, make sure that all utility connections
are properly disconnected. If the unit is returned to its
original position, make sure that any retention devices
and utility connections are properly connected.
• ONLY use the appliance when it is stationary. Mobile
oven racks, mobile plate racks, transport trolleys, and
appliances on casters can tip over when being moved
over an uneven oor or threshold and cause serious
injury.
• ALWAYS apply caster brakes on mobile appliances or
accessories when these are not being moved. These
items could move or roll on uneven oors and cause
property damage or serious injury.
• Be extremely careful when moving appliances because
the food trays may contain hot uids that may spill,
causing serious injury.
• ALWAYS open the appliance door very slowly. Escaping
hot vapors or steam can cause serious injury or death.
• If your gas appliance is installed under an exhaust
hood, the hood must be switched ON when the oven
is in use to avoid the buildup of combustion gases.
Failure to do so may result in serious injury, death, or
property damage.
• NEVER place objects near the oven exhaust vents. This
area is hot and could be a potential ignition source for
a re.
• Do not allow objects to block or obstruct the area
below the oven base. This may result in re, damage
to the equipment, or serious injury.
• Do not use the attached hand-held hose to spray
anything other than the interior of the oven
compartment.
• Do not use the attached hand-held hose on the
surface of a hot cooking compartment. The sudden
temperature change can damage the oven interior.
Allow the oven to cool to a minimum of 150°F (66°C).
Failure to observe this precaution can void the
warranty.
WARNING
This appliance is not intended for use by
persons (including children) with reduced
physical, sensory or mental capabilities,
or lack of experience and knowledge,
unless they have been given supervision
concerning use of the appliance by person
responsible for their safety.
Children should be supervised to ensure
that they do not play with the appliance.
WARNING
DO NOT obstruct or block exhaust flues
or attach any flue extension that may
impede proper burner operation, restrict
the exhaust fumes and cause negative
backdra or the appliance to shut down.
Failure to do so may result in serious injury
or death.

Water Quality Standards
It is the sole responsibility of the owner/operator/purchaser
of this equipment to verify that the incoming water supply
is comprehensively tested and, if required, a means of
“water treatment” provided that would meet compliance
requirements with the published water quality standards
shown below. Non-compliance with these minimum
standards will potentially damage this equipment and/or
components and void the original equipment manufacturer’s
warranty. Alto-Shaam recommends using the Alto-Shaam
Reverse Osmosis System to properly treat your water.

LIFTING INSTRUCTIONS
Remove banding before liing. Li the unit from the
front only, never from the side.
Adjust the forks so that they do not damage any of the
components under the unit. Note that the control side
of the oven is the heaviest portion. Li the unit just
high enough to remove the wooden pallet. Lower the
unit as close to the oor as possible and no more than
2" (50mm) above the oor. Secure hoses and dangling
cords to avoid tangling or damage. When moving the
unit, drive slowly, keep it low to the ground, and use
extreme caution.

NOTICE: To prevent PROPERTY DAMAGE:
Check the dimensions of the doorways and
aisles before attempting to move the oven and
pallet to the installation site.
Do not tilt the oven. Transport the oven in an
upright and level position only.
Slide the preheat strip into place before using
a forkli or pallet jack in between the trolley
guides to avoid damaging the preheat strip
when liing.
