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).
Inspection & Unpacking CAUTION SHIPPING STRAPS ARE UNDER TENSION AND CAN SNAP BACK WHEN CUT. CAUTION THE COUNTER-TOP UNIT WEIGHS 203 POUNDS (92 KG). THE STACKED UNIT WEIGHS 460 POUNDS (207 KG). YOU SHOULD GET HELP AS NEEDED TO LIFT THIS WEIGHT SAFELY. 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.
Water Quality and Treatment TREATED WATER UNTREATED WATER STEAM VENT 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.
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).
Installation and Start-Up WARNING DO NOT CONNECT THE DRAIN DIRECTLY TO A BUILDING DRAIN. BLOCKING THE DRAIN IS HAZARDOUS. 2. CAUTION DO NOT USE PLASTIC PIPE. DRAIN MUST BE RATED FOR VERY HOT WATER. REAR FLUE After the unit has been connected to the gas supply, all gas joints must be checked for leaks. No flame should be used when checking for leaks. A thick soap solution or other suitable leak detector should be used.
Installation and Start-Up 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 VERY HOT WATER. WATER TRAP BUILDING DRAIN IMPROPER DRAIN LINE CONNECTION 5. Factory Stacked Units This section is applicable only if you are installing factory-stacked units. Installing stacked steamers is similar to installing a single unit.
Initial Start-Up WARNING WHEN YOU OPEN THE DOOR, STAY AWAY FROM STEAM COMING OUT OF THE UNIT. THE STEAM CAN CAUSE BURNS. After the steamer has been installed, test it to ensure that the unit is operating correctly. 1. Remove all literature and packing materials from the interior and exterior of the unit. 2. Make sure the water supply line is open. 3. Make sure that the gas supply line is open and that the manual knob on the main gas valve is turned to the “on” position.
Initial Start-Up 9. To shut down the unit, press the ON switch into the off position. The steam generator will then drain. You may also switch off the pilot switch to conserve energy. 10. If the steamer behaves as described, the unit is functioning correctly and ready for use. Automatic Operation of Pilot Once the pilot burner is lit, it essentially functions as a standing pilot.
Operation WARNING ANY POTENTIAL USER OF THE EQUIPMENT MUST BE TRAINED IN SAFE AND CORRECT OPERATING PROCEDURES. DONE LIGHT TIMING INDICATOR LIGHT READY INDICATOR LIGHT SERVICE (“Delime Me”) INDICATOR LIGHT CLEAN CYCLE TOUCH PAD DELIME PORT 12 OM-SN-G Controls Operator controls are on the front right of the unit. The steamer control panel has the following touch pads and indicator lights: 1. The ON/OFF touch pad gets the steamer ready for use, or shuts it off. 2.
Operation WARNING WHEN YOU OPEN THE DOOR, STAY AWAY FROM THE STEAM COMING OUT OF THE UNIT. THE STEAM CAN CAUSE BURNS. The timer is used in three ways: B. 1. In the OFF position the steam generator stays at a low boil or “holding” temperature. 2. When a cook time is set, the unit steams until the timer runs down to OFF. At that time steaming stops, a red light comes on and a beeper sounds. 3. With the timer turned to the ON position, the unit steams continuously.
Cleaning WARNING DISCONNECT THE POWER SUPPLY BEFORE CLEANING THE OUTSIDE OF THE STEAMER. KEEP WATER AND CLEANING SOLUTIONS OUT OF CONTROLS AND ELECTRICAL COMPONENTS. NEVER HOSE OR STEAM CLEAN ANY PART OF THE UNIT. DON’T MIX DE-LIMING AGENTS (ACID) WITH DE-GREASERS (ALKALI) ANYWHERE IN THE UNIT. AVOID CONTACT WITH ANY CLEANERS, DE-LIMING AGENT OR DE- GREASER AS RECOMMENDED BY THE SUPPLIER. MANY ARE HARMFUL.
Cleaning WARNING SHOULD A CLEAN CYCLE BE INTERRUPTED, IT IS POSSIBLE THAT SOME CLEANING SOLUTION IS STILL PRESENT IN THE STEAM GENERATOR. RE-RUN THE CLEAN CYCLE AND CONFIRM THAT THE WATER IS DRAINING. 2. Steam Generator and Cooking Chamber On a regularly scheduled basis, or if the SERVICE light is on, follow the simple de-liming instructions below. This procedure should be followed for each cavity. REMEMBER: DON’T ALLOW DE-LIMING AGENTS TO MIX WITH DE-GREASERS. a. Ensure that the unit is turned on.
Maintenance The steamer is designed for minimum maintenance, and no user adjustments should be necessary. Certain parts may need replacement after prolonged use. If there is a need for service, only authorized representatives should perform the work. Always supply water with a low mineral count that meets the standards outlined in the Water Quality and Treatment section of this manual. If steam or condensate is seen leaking from around the door, take the following steps: 1. Check the door gasket.
