	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.

The steamer has two independent cavities, each with its own base-mounted steam generator.

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.

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
REAR VIEW	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.

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.

Inspection & Unpacking

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.
