The counter-top steamer holds five standard
12” x 20” x 21⁄2” steamer pans.
Equipment Description
Your 5-Pan Gas Convection Steamer is designed to give years of service. It has
a stainless steel cavity (cooking chamber) which is served by an independent
atmospheric steam generator which is gas-heated. A powerful blower circulates the
steam in the cavity to increase heating efficiency.
Each cavity holds up to five steam table pans (12” x 20” x 21⁄2” deep). An 18
gauge stainless steel case encloses the cavity, the steam generator and the control
compartment that houses electrical components. Door hinges are reversible (the door
may be set to open from the left or right). Operating Controls are on the front panel.
The steamer is equipped with fully electronic controls and a button-activated, preprogrammed CLEAN cycle. These units are readily identified by their unique control
panels. The On-Off switch is operated by touch pad controls, and the distinctive
symbol for steam is integrated into the panel.
The drain system on all models includes a spray condenser, which helps keep steam
from escaping from the chamber and cools drain water.

The Steamer will be delivered completely assembled in a heavy shipping carton
strapped to a skid. On receipt, inspect carton carefully for exterior damage.
Carefully cut the straps and detach the sides of the carton from the skid. Pull the
carton up off the unit. Be careful to avoid personal injury or equipment damage from
staples which might be left in the carton walls.
Write down the model number, serial number and installation date. Keep this
information for reference. Space for these entries is provided at the top of the Service
Log in the back of this manual. When starting installation, check packing materials to
make sure loose parts such as the condensate drip tray are not discarded with this
material.

Water Quality and 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.
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.
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 WATER
TREATMENT SYSTEM AND BY DELIMING THE STEAMER REGULARLY.

The second water connection can
reduce treated water requirements.

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 left.
Installation and Start-Up
WARNING
THE UNIT MUST BE INSTALLED BY
PERSONNEL WHO ARE QUALIFIED TO
WORK WITH GAS, 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.
CAUTION
DO NOT INSTALL THE UNIT WITH THE
RIGHT OR LEFT SIDE VENTS BLOCKED OR
WITHIN 12 INCHES OF A HEAT SOURCE
(SUCH AS A BRAISING PAN, DEEP FAT
FRYER, CHARBROILER OR KETTLE).
TO AVOID DRAINAGE PROBLEMS, LEVEL
THE UNIT FRONT TO BACK, OR PITCH IT
SLIGHTLY TO THE REAR.
A. Installation
The counter-top steamer is suitable for installation on or near both combustible
and noncombustible surfaces. Minimum installation clearances are:
Right Side 2 inches
Left Side 2 inches
Rear 6 inches
However, for easy service at least 12 inches clearance is required for the
right side of the unit, and it may not be installed within 12 inches of a heat
source, as stated in the Caution above.
The unit must be installed in a well-ventilated room with an adequate air
supply. The steamer must be installed beneath a ventilation hood, since gas
combustion products exit the appliance.
Any item which might obstruct or restrict the flow of air for combustion and
ventilation must be removed. Do not obstruct the flue cover or any front, side,
rear, or top vents after installation.
The area directly around the appliance must be cleared of all combustible
material. The installation must conform with local codes or, in the absence
of local codes, with the National Fuel Gas Code, ANSI Z223.1, latest edition,
including the following:
The unit and its individual shutoff valve must be disconnected from the gas
supply system during any pressure testing of that system at test pressures in
excess of 1⁄2 PSI (3.45 kPa). It must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during any pressure
testing of the gas supply piping system at test pressures equal to or less than
1⁄2 PSI (3.45 kPa).
1. Electrical Supply Connection
Provide 115 VAC, 60 HZ, 1 PH, 15 AMP service. Bring wire in through
hole on the lower left back panel. Each cavity requires a separate cord
for connections. Local codes and/or the National Electrical Code should
be observed in accordance with ANSI/NFPA 70-1987 (or latest edition).
AN ELECTRICAL GROUND IS REQUIRED. The electrical schematic is
located in the service compartment and in this manual. Maximum load is
21⁄2 AMPs. In Canada, provide electrical service in accordance with the
Canadian Electrical Code, CSA C22.1 Part 1 and/or local codes.
