Equipment Description

The 3-pan steamer holds three standard 12” x 20” x 2½” steamer pans.

The 5-pan steamer holds up to five pans.

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.

CAUTION

SHIPPING STRAPS ARE UNDER TENSION AND CAN SNAP BACK WHEN CUT.

CAUTION

THE 5-PAN UNIT WEIGHS 230 POUNDS (104 KG). THE 3-PAN UNIT WEIGHS 180 POUNDS (82 KG). YOU SHOULD GET HELP AS NEEDED TO LIFT THIS WEIGHT SAFELY.

Inspection & Unpacking

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 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.

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 unitʼs 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.

1.Electrical Supply Connection

Current and power demands for each unit are as shown above.

A.Panel Removal

Open the wiring and control panel by removing screws from the right side panel. Slide the panel forward, and set it aside.

B.Supply Voltage

The unit must be operated at the rated nameplate voltage.

C.Phase Selection

Refer to steamer schematics (Pages 17-18) for wiring information.

D.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 near the terminal block.

E.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 below or to the label on the units back for correct wire size and temperature rating. The equipment grounding wire must comply with the National Electrical Code (NEC) requirements. The schematic on the inside of the units right side cover gives directions for proper connection of the terminal block jumpers. The specified wire must be used, or the unit will not meet Underwriters Laboratories and NEC requirements. The knockout hole is sized for a ¾ inch conduit fitting on the 3-pan and for a one inch conduit fitting on the 5-pan.

F.Branch Circuit Protection

Each Steamer, including individual units of stacked models, should have its own branch circuit protection and ground wire. Current and power demands for each unit are as shown above.
