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 the steam exhaust and must protrude
12" - 20" (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 instruction. 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.

POSITIONING REQUIREMENTS

q In order to ensure proper ventilation, a minimum

distance of at least 4-inches (101mm) must be kept from
the sides of the oven and any adjoining surfaces.

NOTE: Additional clearance is needed for service
access. A minimum distance of 18-inches is strongly
recommended. If adequate service clearance is not
provided, it will be necessary to disconnect the water,
and drain to move the oven with a fork lift for service
access. Charges in connection with inadequate service
access is not covered under warranty.

q Allow a minimum of 4" (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.

q Allow a minimum clearance of 4" (102mm) from the

back of the oven for plumbing connections.

q Allow a 20" (500mm) clearance at the top of the oven for

free air movement and for the steam vent(s) located at
the top.

q Do not install the oven adjacent to heat producing

equipment such as fryers, broilers, etc. Heat from such
appliances may cause damage to the controls of the
Combitherm. Minimum clearance recommended:
20" (500mm)

Place the Combitherm oven on a stable, non-combustible
level horizontal surface. For countertop models, the
oven stand must be level. Level from front-to-back and
side-to-side by means of the adjustable legs. In addition,
the overall height of the oven
should be positioned so the
operating controls and shelves
may be conveniently reached
from the front.

Stand Installation

1) Remove legs from the CT Express

2) Carefully left and set the CT Express on Stand

3) Flush the sides and back of CT Express and Stand

4) Secure the CT Express to Stand in four places with
Screws and Lock Washers.

The leg stand has adjustable legs for leveling purposes.
Stand legs must be bolted to the floor. Air supply vents

are located at the bottom of the oven and must not be
blocked when mounted on a stand.

WATER QUALITY REQUIREMENT

CLEANING PROGRAM.

Water quality is of critical importance when
installing steam producing equipment of any kind,
particularly
equipment. Water that is perfectly safe to drink is
composed of chemical characteristics that directly
affect the metal surfaces of steam producing
equipment. These chemical characteristics differ
greatly from region to region throughout the U.S. and
the world.

hardness; chlorides; total dissolved solids; and other
chemical characteristics, when subjected to high
temperatures, will cause water to have a tendency to
either scale or corrode.

Alto-Shaam has consulted with people who
understand the properties of water in order to
provide water quality standards that meet the
broadest possible range of acceptable water quality
requirements to help protect your investment.

We strongly urge water testing to ascertain the water
quality on site prior to the installation of any steam
producing equipment. Since water quality is an
important issue, Alto-Shaam is committed to provide
as much information as possible to help protect the
investment made in this equipment.

INSTALLATION

A CombiGuard™ Water Filtration System can
be purchased as an option for installation on the
Combitherm oven. This filter, when properly
installed, maintained, and combined with the
required levels of steam generating equipment
maintenance, will help lessen the affect water has
on metal surfaces. It will not, however, provide
complete protection against all water damage from
region to region.

ALTO-SHAAM COMBITHERM WATER QUALITY MINIMUM STANDARDS

CONTAMINANT INLET WATER REQUIREMENTS (UNTREATED WATER)

Free Chlorine Less than 0.1 ppm (mg\L)

Hardness Less than 3 gpg (52 ppm)

Chloride Less than 30 ppm (mg\L)

pH 7.0 to 8.5

Alkalinity Less than 50 ppm (mg\L)

Silica Less than 12 ppm (mg\L)

Total Dissolved Solids (tds) Less than 60 ppm

Due to the complexity of water chemistry, it
is important to understand that water quality
plays a significant role in the longevity of steam
producing equipment. Water quality and required
maintenance of steam generating equipment is the
direct responsibility of the owner/operator. Damage
incurred as a direct result of poor water quality
and/or surfaces affected by water quality is also the
responsibility of the owner/operator. Damage due
to water quality that does not meet the minimum
standards shown below is not covered under the
Alto-Shaam Combitherm warranty.

installation, confirm that water quality standards specified in this manual
are being met. Filtration systems include one filter cartridge. Additional
cartridges can be purchased separately. Refer to page 7 for additional

INSTALLATION

VENTLESS HOOD MODEL

The Ventless Hood option is factory installed
directly on the top of the Alto-Shaam Combitherm
oven. The hood is designed to vent clean air back
into the kitchen, filtering vapors and grease. A
high-power fan draws steam and fumes into the
hood intake and out the top surface exhaust vent.
Fumes and vapors are circulated through filters.
An activated charcoal filter cleans the air before
venting it out the top of the hood.

OPERATION

2

1

1. Turn the ventless hood power knob “ON”.

2. Indicator light will illuminate.

3. Wait fi ve seconds, then press the Combitherm

oven power “ON”.

FILTER DOOR LATCH

Using a coin or screwdriver,
turn to open; reverse procedure
to close and latch.

Hood and oven will not operate
unless this is closed properly.

INDICATOR LIGHT

If the indicator light does not
illuminate, the filters may be
missing or not properly aligned.
Check them for proper positioning.
Ventless hood and oven will not
operate unless the hood is closed
properly.

Timed Latching Mechanism: In
order to evacuate steam and grease­laden air from the oven interior, this
mechanism prevents the operator
from fully opening the oven door for
20 seconds. Longer wait times can
be programmed into the control. The
mechanism automatically disengages
at the end of a pre-set time allowing
full door extension.

Emergency Latch Release: This
release is to be used ONLY if
the timed latch mechanism is
not working or in the event of a
power outage. Repeated use of the
emergency release may damage
the switching mechanism. Latch is
located on the right side of the oven,
toward the back.

1. Charcoal Filter: The charcoal filter should be

inspected for contaminant's on a regular basis.
Replacement must be made at a minimum of
three month intervals — more often if heavy
contaminant's are visible or if the filter no
longer controls odors.

To remove the charcoal filter, pull and slide out.

When replacing the filter, ensure that the filter
clip is in place at rear of the filter. Make certain
the air flow arrow(s) point toward the hood fan
(back of unit), and that the filter is replaced
using the filter track in the metal back plate
provided with the hood.

2. Grease Filter: Cleaning frequency should be

based on oven usage with a maximum of two
weeks between cleaning if the oven is used for
non-grease laden products or steam applications
only. Grease laden products require cleaning
frequency of at least once a week.

Remove the grease filter by pulling it straight

out of the housing. Place the filter in the
dishwasher or wash separately by placing in
hot, soapy water until all grease and particles
have been removed. Rinse thoroughly. Allow
the filter to air dry before reinstalling.

To replace the grease filter, the metal handles

on the filter casing should be facing toward the
front of the unit.

WATER SUPPLY AND DRAINS:

Verify hook-up to ONE (1) cold water supply line with a 3/4" (19mm) G
water connection supply line. Verify inlet water pressure is at a minimum
of 30 PSI (2.8 bar). Maximum water pressure is not to exceed 90 PSI
(6 bar). Verify drain diameter of 1-1/2" (38mm) with a positive descending
slope, and with a 2" (51mm) air gap which is free of obstructions before
connection to the site drain. Verify 1/8" (3.2mm) pitch to 10' (305cm) of
drain line. Materials must withstand temperatures up to 200°F (93°C).
IMPORTANT: Alto-Shaam has listed Water Quality Requirements in the

installation manual for this equipment. It is the responsibility of the end
