WARNING: BLOCKING THE STEAM GENERATOR OR CAVITY DRAIN SCREEN MAY BE HAZARDOUS.
IMPORTANT: IMPROPER DRAIN CONNECTION WILL VOID WARRANTY.
WARNING: WHEN YOU OPEN THE DOOR, STAY AWAY FROM STEAM COMING OUT OF THE UNIT. STEAM CAN
CAUSE BURNS.
WARNING: BEFORE CLEANING THE OUTSIDE OF THE STEAMER, DISCONNECT THE ELECTRIC POWER SUPPLY.
KEEP WATER AND CLEANING SOLUTIONS OUT OF CONTROLS AND ELECTRICAL COMPONENTS.
NEVER HOSE OR STEAM CLEAN ANY PART OF THE UNIT.
WARNING: ALLOW COOKING CHAMBERS TO COOL BEFORE CLEANING.
WARNING: CAREFULLY READ THE WARNINGS AND FOLLOW THE DIRECTIONS ON THE LABEL OF EACH
CLEANING AGENT. USE SAFETY GLASSES AND RUBBER GLOVES AS RECOMMENDED BY DELIMING
AGENT MANUFACTURER.
WARNING: DO NOT MIX DE-LIMING AGENTS (ACID) AND DE-GREASERS (ALKALI) IN THE STEAM GENERATOR
OR ON THE COOKING CHAMBER WALLS.
WARNING: DO NOT PUT HANDS OR TOOLS INTO THE COOKING CHAMBER UNTIL THE FAN HAS STOPPED
TURNING.
WARNING: DO NOT OPERATE THE UNIT UNLESS THE REMOVABLE RIGHT SIDE PANELS HAVE BEEN RETURNED
TO THEIR PROPER LOCATIONS.
NOTICE: DO NOT USE A CLEANING OR DE-LIMING AGENT THAT CONTAINS ANY SULFAMIC ACID OR ANY
CHLORIDE, INCLUDING HYDROCHLORIC ACID. IF THE CHLORIDE CONTENT OF ANY PRODUCT IS
UNCLEAR, CONSULT THE MANUFACTURER.
NOTICE: USE NO DE-GREASER THAT CONTAINS POTASSIUM HYDROXIDE OR SODIUM HYDROXIDE OR THAT
IS ALKALINE.

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.

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.

Inspection & Unpacking
CAUTION
SHIPPING STRAPS ARE UNDER TENSION
AND CAN SNAP BACK WHEN CUT.
CAUTION
THIS UNIT WEIGHS 550 POUNDS. GET HELP
AS NEEDED AND USE MATERIAL HANDLING
EQUIPMENT TO MOVE IT.
Your steamer will be delivered completely assembled in a heavy shipping carton and
attached to a skid. On receipt, inspect the carton carefully for exterior damage.
Carefully cut the straps around the carton and detach the sides of the carton from the
skid. Be careful to avoid personal injury. Strap edges may be very sharp, particularly
where cut.
Write down the model number, serial number and installation date. Space for these
entries is provided in the Service Log at the back of this manual. Keep the manual near
the equipment for reference and update as needed.
When installing, use material handling equipment to lift the unit straight up from the skid.
Check packing materials for any loose parts.
