The 3-pan steamer holds three standard

12” x 20” x 2½” steamer pans.

Equipment Description

Your 3-pan or 5-pan atmospheric 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 electricallyheated. A powerful blower circulates the steam in the cavity to increase heating efﬁciency.

The cavity holds up to ﬁve or three steam table pans (12” x 20” x 2½” 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 steamers are 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 new models also have fewer panel louvers on the right side.

From the rear the units are distinguished by the addition of a fuse box, which lets operators change fuses without removing panels.

The drain system on all models includes a spray condenser, which helps keep steam from escaping from the chamber and cools drain water.

The 5-pan steamer holds up to ﬁve pans.

Water Conditioning

It is essential to supply the steam generator with water that will not form scale. Even though the steam generator is engineered to minimize scale formation, scale development depends on the hardness of your water and the number of hours per day you operate the equipment.

Most water supplies are full of minerals which form scale. It is this scale which could lead to an early component failure.

Your water utility can tell you about the minerals in your water. The water going to the steam generator should have no more than 10 to 30 parts per million (ppm) total dissolved solids (TDS) and should have a pH (acidity rating) of 7.0 or higher. 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 are not speciﬁcally designed to work with steamers and combination ovens.

2. A well-maintained water treatment system and a regular cartridge replacement schedule is essential.

Stacked steamers

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 USING AND MAINTAINING A SOFTENER AND BY CLEANING (DELIMING) THE STEAMER REGULARLY.

On both the 3-pan and 5-pan, the dual water connections are side by side on the rear of the unit. When seen from the back of the unit, the treated (softened) water intake is on the right.

Installation

WARNING

DO NOT CONNECT THE DRAIN DIRECTLY

TO A BUILDING DRAIN. BLOCKING THE

DRAIN IS HAZARDOUS.

CAUTION

DO NOT USE PLASTIC PIPE. DRAIN MUST BE

RATED FOR BOILING WATER.

IMPORTANT

DO NOT ALLOW WATER TRAPS IN THE LINE.

A TRAP CAN CAUSE PRESSURE BUILD-UP IN

THE CAVITY, WHICH MAY CAUSE THE DOOR

GASKET TO LEAK.

2. Water Connection(s)

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 and must deliver a ﬂow rate of 1.5 to 3.0 gallons per minute. If pressure is above 60 PSIG, a pressure regulator will be needed.

A ¾ inch female NH connector (garden hose type) is used to attach the water

supply to the inlet valve. Minimum inside diameter of the water feed line is ½ inch. Use a washer in the hose connection. Do not allow the connection to leak, no matter how slowly. The dual water standard connection, treated (softened) water goes to the right (seen from the rear of the unit), and untreated water to the left. Connections for both are as shown on Page 5.

3. Drain Connection

Level the steamer front to back, or pitch it slightly to the rear (maximum ¼ inch)

by adjusting the bullet feet on the stand or cabinet base.

A 2 inch (5-pan) or 1½ inch (3-pan) ID hose may be attached to the drain pipe

(supplied).

There must be a free air gap between the end of the hose and the building drain.

The free air gap should be as close as possible to the unit drain. There must also be no other elbows or other restrictions between the unit drain and the free air gap.

Install the drain line with a constant downward pitch.

4. Factory-Stacked Units

This section is applicable only if you are installing factory-stacked units. If you

plan to stack steamers yourself, whether purchasing a new one for stacking or a kit to stack two units you already own, you will require a ﬁeld stacking kit.

Installing stacked steamers is similar to installing a single unit. The steamers are

stacked and assembled at the factory and delivered with the water connections and drain hoses required for a single point connection.

A. Water Connection At the water inlet valve a ¾ inch female NH connector (garden hose type) is

used for the water supply. The dual water connection has two connections to be made. Treated water (softened) is connected to the right valve ﬁtting (looking from the rear of the unit) and untreated water to the left ﬁtting.

B. Electrical Supply Connection Separate, individual electrical connections will be required for each

steamer in the stack. Each Steamer must have its own branch circuit protection.

C. Drain Connection Steamers must be leveled front to back, or pitched to the rear (maximum ¼

inch) by adjusting the bullet feet on the cabinet or stand base.

For a double 3-pan stack a 1½ inch and for double 5-pan stack a 2 inch ID

hose may be attached to the unit drain. It must be rated for boiling water.

5. Counter-Mounted Units

This section is applicable if the steamer will be mounted to a counter. All four

edges of the bottom of the steamer must be sealed with RTV to the counter if the 4 inch legs are not used. Counter must be made of a noncombustible material such as metal or tile.

Ensure that there is a free air gap between the end of the unit drain and the

building drain. This gap should be as close as possible to the unit drain. Do not allow elbows or restrictions between the unit and the free air gap.

Install the line with a constant downward pitch.
