BASIC INSTALLATION SITE REQUIREMENTS
HOOD INSTALLATION IS REQUIRED
•Installation surface must be level.
•Do not install adjacent to flammable surfaces.
•Deep fat fryers or similar heat producing
equipment must not be installed in the
immediate vicinity of the hand shower.
The oven must remain on the pallet while being moved
to the installation site with fork lift or pallet lift truck.
Do not tilt the oven.
VENTILATION REQUIREMENTS
A steam ventilation hood is mandatory for the operation of the oven. The ventilation hood must be installed
in accordance with local building codes for steam exhaust and must protrude 12-inches to 20-inches
(300mm to 500mm) over the front side of the oven. A grease filter must be located in the protruding area of
the hood. Grease filters should be thoroughly cleaned on a regular basis following manufacturer's
instructions. Ventilation hoods must ensure an adequate amount of incoming air during operation and must
be operated whenever the combination oven/steamer is used in order to avoid the accumulation of
condensation in the hood area.
Where automatically operated appliances are vented through a ventilating hood or exhaust
system equipped with a damper or with a power means of exhaust, provisions shall be made
to allow the equipment to operate only when the damper is open to a position to properly
vent the appliance and when the power means of exhaust is in operation.
IN ACCORDANCE WITH NFPA 54 COMMONWEALTH OF MASSACHUSETTS ONLY.
If a ventless hood is to be installed, we
recommend the Combitherm Ventless Hood for the
appropriate model oven. Ventless hoods are
available for the Combitherm models
6•10, 7•14, 10•10, and 10•18 (VHML-10) electric.

POSITIONING ON SITE
Before removing the oven from the pallet for positioning on
site, it is important to remove the drip tray to prevent
damage to the tray caused by the lifting forks. The drip tray
is fastened to the bottom of the oven with three sheet metal
screws as illustrated. This requirement pertains to the
following models.
This step does not
pertain to models
12•20ML and 20•20ML.
Lift the oven from the pallet with a fork lift or
pallet lift truck positioned at the front of the
oven. To avoid damage, position the lift forks to
the left of the condenser as indicated in one of
the two diagrams shown below. For additional
damage protection, the use of two wooden
boards, placed between the bottom of the oven
and the lifting forks, is strongly recommended.
After the oven is correctly positioned on site,
reattach the drip tray.

INSTALLATION REQUIREMENTS
■■
■■Do not install oven adjacent to flammable
surfaces. Strictly observe all local fire
safety regulations.
■■
■■In order to ensure proper ventilation, a
minimum distance of at least 6-inches
(152mm) must be kept from the control
panel side [LEFT] of the oven and any
adjoining surfaces.
NOTE: In addition to ventilation
requirements, additional clearance
is needed for service access. A
minimum distance of 18-inches
(457mm) is strongly recommended.
■■
■■Allow a minimum of 4-inches (102mm) from
the right side of the oven to allow the door
to open to at least a 90°angle. Fully opened,
the door will extend up to a 225°angle. If
the oven is furnished with the retractable
door option, allow a minimum clearance of
6-1/2-inches (16cm).
■■
■■Allow a minimum clearance of 4-inches
(102mm) from the back of the oven for
plumbing connections.
■■
■■Allow a 20-inch (50cm) clearance at the top of
the oven for free air movement and for the
steam vent(s) located at the top [RIGHT-REAR].
■■
■■Do not install the oven adjacent to heat
producing equipment such as fryers,
broilers, etc. Minimum clearance
recommended: 20-inches (50cm).
Place the Combitherm oven on a stable, LEVEL
horizontal surface. For counter-top models, the
oven stand must be level. In addition, the overall
height of the oven should be positioned so the
operating controls and shelves may be
conveniently reached from the front.

WATER SUPPLY
CONNECT TO POTABLE (DRINKABLE) COLD WATER ONLY
WATER PRESSURE REQUIREMENTS:MINIMUM 30 PSI (2 BAR)
MAXIMUM 90 PSI (6 BAR)
Flush the water line at the installation site before connecting the oven to the water supply. A shut-off valve and
approved back-flow preventer must be installed when connecting the oven to the cold water intake. The water
supply line must be a minimum of 3/4-inch (NPT) (19mm). A hose connector is supplied for flexible hose
connection to the COLD water source. Connected water should test at hardness level of 5 to 9 grains per gallon
(85 to 154 ppm). A water filtration system is recommended if the water supply is between 5 and 9 gpg of
hardness. If water tests over 18 gpg of hardness (344 ppm), the
installation of a water softener to maintain oven function is strongly
recommended.
PIPE SEALING TAPE (TEFLON®)MUST BE USED
AT ALL CONNECTION POINTS.
The use of a pipe sealing compound is not recommended.
THE SHUT-OFF VALVE MUST BE IN THE OPEN POSITION
WHEN THE OVEN IS BEING USED.
The hand shower spray hose is installed adjacent
to the cold water intake connection. A ball valve
is installed on the oven for hose connection to the
COLD water source. Assemble the washer and
the flexible hose on the ball valve and hang the
spray handle on the holder previously installed
on the oven.
Alto-Shaam now offers an improved water filtration system for
Combitherm®. The CombiGuard™triple-guard water filtration
system filters dirt, sediment, and other debris as small as 1/2
micron. This system also significantly reduces chlorine content to
protect against corrosive chlorine compounds. CombiGuard
improves equipment efficiency, reduces service requirements and
extends the life of the Combitherm. Filtration system includes one
filter cartridge. Additional cartridges (FI-26356) can be
purchased separately.

The drain thread is 1-1/4-inch (32mm) NPT.
A union is required. Install a 1-1/4-inch
(32mm) diameter drain line. The drain line
must always be a positive gradient away
from the Combitherm oven and not more than
12-inches (305mm) before an air gap.
NOTE: In the U.S.A., this equipment is to be
installed to comply with the Basic
Plumbing Code of the Building
Officials and Code Administrators
International, Inc. [BOCA], and the
Food Service Sanitation Manual of the
Food & Drug Administration [FDA].
If several units are to be connected to one
drain pipe, the dimensions of the pipe must
be sufficient to allow an unobstructed water
drain system.

ELECTRICAL INSTALLATION
An electrical wiring diagram is located behind
the control panel on the left side of the oven.
The oven must be installed by a qualified
electrician. This appliance must be branch
circuit protected with proper ampacities, in
accordance with the wiring diagram located in
the electrical compartment of the oven. The
oven must be properly grounded in accordance
with the National Electrical Code and applicable
local codes.
CAUTION
Wire size for the main incoming power to the unit
must match the minimum size listed in the
specifications applicable to the specific oven model.
For supply connections, locate the wire size posted on
the label located on the electrical control box cover,
behind the service panel or elsewhere listed in this
manual.
When connecting to a Delta-B (wild leg) on a
3-phase system, the wild leg must be connected
to line 3.
Before operating the oven, check all cable
connections in the electrical connection area
for tightness since connections can loosen
during transport.
NOTE: After both water and electrical
connections have been completed,
operate the oven in any cooking
mode for a period of 15 minutes and
recheck the main power connections
at the terminal block to make
certain they remain tight.
