Equipment Description
WARNING
BEFORE REMOVING ANY PARTITION OR
PANEL, TURN OFF THE ELECTRICAL POWER
AND LET THE FAN STOP ROTATING.
BEFORE WORKING ON ANY ELECTRICAL
COMPONENT, DISCONNECT THE POWER
SOURCE FROM THE UNIT.
WARNING
THE UNIT MUST BE INSTALLED BY
PERSONNEL WHO ARE QUALIFIED TO
WORK WITH ELECTRICITY AND PLUMBING.
IMPROPER INSTALLATION CAN CAUSE
INJURY TO PERSONNEL AND/OR DAMAGE TO
THE EQUIPMENT. THE UNIT MUST BE
INSTALLED IN ACCORDANCE WITH
APPLICABLE CODES.
Your Atmospheric Convection Steamer is designed to give years of service. It has two
stainless steel cavities (cooking chambers) which are served by twin, independent
atmospheric steam generators which are electrically-heated. A powerful blower
circulates the steam in each cavity, to increase heating efficiency.
Each cavity holds up to three steam table pans (12”x 20” x 2½”). A 18 gauge stainless
steel cabinet encloses the cavities, the steam generators and the control compartment
that houses electrical components. Door hinges are reversible (the doors may be set to
open from the left or right). Operating Controls are on the front panel.
Steamers are equipped with fully electronic controls and a button-activated, preprogrammed CLEAN cycle. The On-Off switch is a touch pad control, and the
distinctive symbol for steam is integrated into the panel design.
The drain system includes a spray condenser, which reduces condensate temperature
and helps keep steam from escaping through the drain.
The steamer has two independent cavities, each
with its own base-mounted steam generator.

REAR VIEW
Water Quality & Treatment
It is essential to supply the steam generator with water that will not form scale. Even
though the steam generator/boiler is engineered to minimize scale formation, scale
development depends on the hardness of your water and the number of hours you
operate the equipment each day.
Most water supplies contain minerals which form scale. It is this scale which could lead
to an early component failure.
Your local water utility can tell you about the minerals in your water. The water going
to the steam generator should have between 30 and 40 parts per million (ppm) total
dissolved solids (TDS) and should have a pH (acidity rating) of 7.0 to 9.0. Please follow
these simple precautions:
1. The best way to prevent scale is to use a Water Treatment System which has been
specifically designed for steamers and combination ovens. Do not rely on unproven
water treatment systems sold for scale prevention and removal. They may not be
specifically designed to work with steamers and combination ovens.
2. A well-maintained water treatment system and a regular cartridge replacement
schedule is essential.
3. Using a Water Treatment System will provide longer steam generator/boiler life,
higher steam capacity, and reduce maintenance requirements. To avoid mineral
build up in the steam generator, blow down the generator after every 5 hours.
4. If you notice a slowdown in steam production or an increase in deliming, have the
steamer checked for scale build-up. This could be an indication that the water
treatment cartridges need replacing. Heavy scale reduces the unit’s ability to boil
water, and can even cause component failure.
MINIMIZE SCALE PROBLEMS BY INSTALLING AND MAINTAINING A WATER TREATMENT
SYSTEM AND BY DELIMING THE STEAMER REGULARLY.
The steamer features two separate water inlets — one for the steam generator/boiler
(treated water), the other for the spray condenser (untreated water). The second intake
will reduce treatment requirements resulting in significant savings.
The dual water connections are side by side on the rear of the unit. When seen from the
back of the unit, the treated water intake is on the right.

UNIT
FRONT
A. Electrical Supply Connection
1. Access for Connection, Panel Removal
Open the wiring and control panel by removing screws from the front
panel. Lift the panel, and swing its bottom toward you. Set the panel aside.
2. Supply Voltage
The unit must be operated at the rated nameplate voltage. A temporary
fluctuation of plus or minus 10 percent is acceptable.
3. Phase Selection
Refer to the steamer schematic (at the back of this manual) for wiring
information.
4. Terminal Block
The terminal block for incoming power is located at the back of the control
compartment. The ground terminal is located in the wiring compartment
next to the terminal block. The unit must have a separate ground wire for
safe operation. Minimum size for the ground wire is 10 AWG.
5. Supply Wire
To determine the type of wire you need for the power supply, find the
operating voltage and number of phases on the unit data plate. Refer to the
table provided on the next page or to the label on the unit’s back for the
correct wire size and insulation temperature rating. The “Electrical Supply
Connection” label inside the unit gives directions for proper connection
of the terminal block jumpers. The wire specified has to be used, or the
unit will not meet Underwriters Laboratories and National Electrical Code
requirements.
Control
Box
The knockout hole is sized for a one inch
conduit fitting. Pass the wire up the back

Installation
B. Water Connection
Install a check valve to prevent back flow in the incoming cold water line, as
required by local plumbing codes. Water pressure in the line should be between
30 and 60 PSIG (210 and 420 kPa). If pressure is above 60 PSIG, a pressure
regulator will be needed.
A ¾ inch NH connector (garden hose type) is used to attach the water supply to
the water inlet valve. The minimum water feed line diameter is ½ inch (13mm).
Use a washer in the hose connection. Do not allow the connection to leak, no
matter how slow it may be.
If you have the dual water connection option, put the treated water (softened) to
the right intake (looking from the rear of the unit), and untreated water to the left.
Connections for both are made as described above.
C. Drain Connection
The steamer must be leveled front to back. A 1½ inch (38mm) ID hose may be
attached to the drain pipe by means of a hose.
Do NOT use plastic pipe. The drain must withstand boiling water.
Don’t allow water traps in the hose.
Install the drain line with a constant downward pitch. Do not allow any water
traps in the line. A trap can cause pressure to build up inside the cavity during
steaming, which will make the door gasket leak.
IMPROPER CONNECTION OF THE DRAIN WILL VOID YOUR WARRANTY.
