INSTALLATION INSTRUCTIONS

GENERAL
The SX-3 and SX-5 steamers are single compartments electric pressureless steam cookers with an internal electric steam generator that maintains water temperature at approximately 205 Deg F. SX-3 is rated 7.5 kW as standard; 10 kW is optional. SX-5 is rated 15 kW as standard; 12 kW is optional.
At high altitude locations, a lower temperature is required to achieve atmospheric steaming.
Contact your authorized service office to have the thermostat adjusted if the steamer will be operated at high altitudes.
INSTALLATION
UNPACKING
IMMEDIATELY INSPECT FOR SHIPPING DAMAGE
Immediately after unpacking the steamer, check for possible shipping damage. If the steamer is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery. Prior to installation, verify that the electrical service agrees with the specifications on the machine data plate which is located on the left side panel.
LOCATION
Allow space for plumbing and electrical connections. Allow adequate access for operating and servicing the steamer (36” at the front of the steamer and 15” above the steamer).
LEGS (OPTIONAL)
If the optional 4” adjustable legs are used, remove the four leveling feet on the bottom of the steamer.
LEVELING FEET (Standard) OR 4” ADJUSTABLE LEGS (Optional)
Thread the four 2” leveling feet shipped in a bag inside the steamer cabinet into the threaded holes on the bottom corners of the steamer. Or, thread the four optional 4” adjustable legs into the threaded holes on the bottom corners of the steamer.
LEVELING
Using a spirit level or pan of water in the bottom of the steamer, adjust the leveling feet or the feet on the adjustable legs to level the steamer front- to-back and side-to-side. After the drain is connected, check for level by pouring water onto the floor of the compartment. All water should drain through the opening at the back of the compartment cavity.
ANCHORING STEAMER (Without Legs)

1. Place the steamer in the desired location on the leveled countertop and mark four corners. Remove the steamer and drill 1/2” holes as indicated in Figure 1.
2. Apply a bead of RTV or another equivalent sealant around the bottom perimeter edge of the steamer. If anchoring the steamer, this bottom seal is necessary to meet NSF requirements.
3. Set the steamer on the counter and bolt down securely with 3/8 – 16 bolts (not supplied).

STACKING KIT
Follow instructions in the stacking kit when installing stacked convection steamers.

PLUMBING CONNECTIONS

WARNING
Plumbing connections must comply with applicable sanitary, safety, and plumbing codes.

The water supply inlets are provided with 3/8” (10 mm) compression fittings for 3/8” O.D. copper tubing. The water supply line pressure should be 25 – 50 psi (170 – 345 kPa) for each line. The water supply to the generator tank is separate from the water supply to the cooling system where steam is condensed before entering the drain line. Install line strainers (not provided). A manual shutoff valve for each supply line must be provided convenient to the steamer. Treated water feeding the boiler inlet supply is recommended, and untreated water feeding the condensing water inlet. Hook-ups are labeled on the back of the steamer. Units are provided with an adjustable condensing water valve. It has been factory set to 2-1/2 turns open, which will suit most installations. Adjust as required to suit local water inlet temperature and pressure. Turn the screw clockwise to decrease flow or counterclockwise to increase flow.

DRAIN CONNECTIONS (FIGURE 2)

The drain connection (Fig. 2) must be 1” IPS down, preferably with one elbow only, the maximum length of 2 feet horizontal before the open-air gap, and piped to an open-air gap type drain. The drain pipe should be copper. DO NOT use PVC pipe – PVC pipe may lose its rigidity or glue may fail.

CAUTION
In order to avoid any back pressure in the steamer, do not connect solidly to any drain connection.

WATER QUALITY

The water supply connected to this steamer should contain no more than 2.0 grains of hardness per gallon with a pH from 6.8 to 7.3. This degree of hardness and pH can easily be obtained with the use of a properly maintained water softener. Water supplies vary from one location to another. A local water treatment specialist should be consulted before installing any steam- generating equipment. Untreated water contains scale-producing minerals that can precipitate onto the surfaces in the generator. Due to the temperatures in the generator, the minerals can bake onto the surfaces and components. This can result in early component failure and reduced product life.

Mineral scale on components causes several problems:

1. The surfaces of the heating devices become coated with scale, reducing the heat transfer efficiency. This can produce hot spots on the heating elements and result in premature failure.
2. The water level probes become coated with scale. The scale will bridge across the probe insulator from the metal extension which senses the water level in the generator cell. Once this scale becomes wet, the water level control is unable to maintain the proper water level in the generator. This situation may cause an electric heating element to fail if the element is not adequately covered by water.

Strainers and filters will NOT remove minerals from the water.
Refer to REMOVAL OF LIME SCALE DEPOSITS, page 16.

VENT HOOD
Some local codes may require the steamer to be located under an exhaust hood. Information on the construction and installation of ventilating hoods may be obtained from Vapor Removal from Cooking Equipment, NFPA standard No. 96 (latest edition).

ELECTRICAL CONNECTIONS

WARNING
Plumbing connections must comply with applicable sanitary, safety, and plumbing codes.

Electrical grounding must be provided in accordance with local codes or in the absence of local codes, with the National Electrical Code, ANSI/NFPA70, or the Canadian Electrical Code, CSA C22-2, as applicable. Use copper wire suitable for at least 90 degrees Celsius. The steamer must be grounded. The wiring diagram is located on the right-side panel as you face the steamer.

TESTING PROCEDURES

CAUTION

The COOKING light is lit.
When the buzzer sounds, turn the timer to OFF. The steamer is now ready to cook.
COOK
After the preheat cycle, the READY light should be ON.
Place pans of food in the cooking chamber. Close the door. Set the timer. Steam flows into the compartment and the COOKING light is lit. Opening the door will interrupt cooking; resume by closing the door. At the end of the cooking cycle, the COOKING light goes off, the buzzer sounds, and steam stops being supplied to the cooking chamber. To stop the buzzer, turn the timer to OFF.
SHUTDOWN
Turn the main power switch OFF – the boiler will automatically blowdown. Leave the compartment door open to allow the inside to dry out. For an extended shutdown, turn the main power switch OFF, and turn the power and water supply OFF.
Each compartment is equipped with a removable drain screen. Frequently check the drain screen for accumulation of food particles. Should food particles accumulate against, or clog the drain screen, remove it, clean it thoroughly and then replace it in its original position.

Frequently check that the compartment drain and plumbing is free of all obstructions. Never place food containers, food or food portion bags in the cooking compartment in such a way that the compartment drain becomes obstructed.
CONSTANT STEAM FEATURE – OPTIONAL FEATURE
A switch has been added to control this feature. It is located below the timer under the heading “COOKING MODE”.
OPERATION WITH THIS FEATURE
Operation for Timed Cooking
This switch must be positioned to the right, towards the heading “TIMED COOKING”. The operator then must select the time required for the cooking by setting the timer dial to the desired time from “0 to “60” minutes. At the end of the cooking time an audible buzzer will sound. Operation for Constant Steam The switch must be positioned to the left towards the heading “CONTINUOUS COOKING”. This mode will provide continuous steam to the cooking chamber until the operator either turns the selector switch to  The “TIMED COOKING” position or turns the power switch to the “OFF” position.
SHUT DOWN
Turn the timer dial to the “OFF” position. Turn the main power switch to the “OFF” position. For an extended shutdown, turn the main power switch off, and turn the power and water supply off.
STEAM COOKING
Your steamer efficiently cooks vegetables or other foods for immediate serving. Steam cooking should be carefully time controlled. Keep hot-food- holding time to a minimum to produce the most appetizing results. Prepare small batches, cook only enough to start serving, then cook additional amounts to meet demand. Separate frozen foods into smaller pieces to allow more efficient cooking. Use a pan cover for precooked frozen dishes that cannot be cooked in the covered containers in which they are packed if they require more than 15 minutes of cooking time. When a cover is used, approximately one-third of additional cooking time is necessary. Cooking time for frozen foods depends on the amount of defrosting required. If time permits, allow frozen foods to partially thaw overnight in a refrigerator. This will reduce their cooking time.
PREPARATION
Prepare vegetables, fruits, meats, seafood, and poultry normally by cleaning, separating, cutting, removing stems, etc. Cook root vegetables in a perforated pan unless juices are being saved. Liquids may be collected in a solid 12 inch by 20-inch pan placed under a perforated pan. Perforated pans are used for frankfurters, wieners, and similar items when juices do not need to be preserved. Solid pans are good for cooking puddings, rice, and hot breakfast cereals. Vegetables and fruits are cooked in solid pans to preserve their own juices. Meats and poultry are cooked in solid pans to preserve their own juices or to retain broth. Canned foods may be heated in their opened cans (cans placed in 12 inches by 20 inch solid pans) or the contents may be poured into solid pans.

ACCEPTABLE PAN SIZES

The steamer accommodates combinations of 12” x 20” pans, solid or perforated.

Depth of Pan
1″| 2.5″| 4″| 6″
SX-3| 6| 3| 2| 1
SX-5| 10| 5| 3| 2

DRAINING THE GENERATOR
Drain the steam generator after each day’s use to flush out minerals and minimize scale buildup. The generator drains automatically for about 4 to 6 minutes after the main power switch is turned off.

MAINTENANCE

WARNING
Disconnect the power supply to the appliance before cleaning or servicing.
CAUTION
Live steam and accumulated hot water in the compartment may be released when the door is opened.
CAUTION
The appliance and its parts are hot. Use care when operating, cleaning, and servicing the appliance.

COLDWATER CONDENSER
The steamer is equipped with a cold water condenser in the rear of the cooking chamber which helps to condense the steam prior to discharge into the drain. The steamer freely vents itself by the negative pressure created by the condensate water drainage. This negative pressure prevents steam leakage around the door gasket and helps draw the steam
through the cooking compartment. Steam leakage at the door may indicate a plugged or improperly installed drain.
REMOVAL OF SCALE DEPOSITS
It is recommended that your steamer be deemed once a month, or more often if necessary. Should your steamer develop a heavy buildup of limescale deposits, use CLR. Before beginning deliming procedures, ensure that water is not overflowing into the cooking compartment. The generator tank has a removable sealed tank cover. The main purpose of the removable cover is for inspection of the interior of the tank for the lime build-up and easy removal of large pieces of lime that will not flush out the drain. Should the tank cover have to be removed, check the condition of the sealing gasket before replacing the cover. The hold-down bolts are to be tightened to 160 inch-pound torque each.

NOTICE
Contact the factory, the factory representative, or the local service company to perform maintenance and repairs.
WARNING
Disconnect the power supply to the appliance before cleaning or servicing.

1. Drain the steam generator by setting the main power switch to OFF. Set a cooking timer to “0FF”.
2. Set the main power switch to DELIMA.
3. Delima port (A) is located on the left side at the rear of the unit. Unscrew plug from elbow to allow CLR solution to be poured in using a tube and funnel. Pour in 28 ounces of solution into the generator (pour slowly to avoid spillage). Remove tube and funnel. Screw the plug back into the elbow so that it is sealed.
4.  Turn the main power switch to ON.
5.  Allow the steamer to remain in the READY cycle for 1-1/2 hours, then turn the main power switch OFF and allow the generator to drain.
6. FLUSH CYCLE: Turn the main power switch to ON. When the READY light comes on, turn the main power switch to OFF to drain the generator. Repeat this step three times to completely flush the generator.
7. Clean exterior and interior. Use a mild solution of soap and water. Rinse with a clean cloth. Dry with a soft cloth. Leave compartment door open when not in use.

The steamer is now ready for use. Turn off for overnight shutdown.

ADJUSTMENT FOR HIGH ALTITUDE LOCATIONS

NOTICE
Contact the factory, the factory representative or the local service company to perform maintenance and repairs.

The steamer has been factory set so that when it is ON and in the READY mode, it will maintain water temperature in the steam generator tank at approximately 205 degrees Fahrenheit (just below the water boiling point). However, for high-altitude locations, the authorized servicer must adjust the steamer temperature lower. To adjust:

1. Remove the side panel and turn the control panel power switch to ON.
2. Open the compartment door, and after about 5 minutes, steam will be seen, entering the cooking compartment.
3.  Turn the thermostat shaft counterclockwise to a lower temperature until steam just ceases to enter the cooking compartment and the READY light goes on.
4. Replace the side panel.
5. Follow TESTING PROCEDURES in this manual.

TROUBLESHOOTING

WATER FLOWS INTO THE DRAIN DURING THE SHUTDOWN
When the steamer is shut down and cold water is running continuously into the open drain, either or both solenoid valves did not close when the steamer was turned off.

1.  Disassemble solenoid valve(s) and examine for scale or foreign particles lodged in the diaphragm or core tube.
2. Clean valve(s) thoroughly and reassemble, or replace valve(s).

WATER OVERFLOWS INTO THE COOKING COMPARTMENT
When the steamer is first turned on for the day, the following conditions occur:

• READY light does not come on after about 5 minutes,
• Water begins to overflow into the cooking compartment,
• The water fill solenoid valve is open,

Any or all of these symptoms may indicate a problem with the operating probe due to either:

1.  Probes not sensing water, thereby not operating fill solenoid.
2. Excessive scale build-up on the operating probe. This acts as an “insulation” and prevents the probe from sensing the water level. It is, therefore, unable to close the water fill (solenoid) valve to shut off the water.
   As a temporary solution, with power OFF, unscrew probes, check visually, and clean or chip off the sealant. Replace probe. This problem is an indication of severe harmful water conditions which should be corrected immediately to avoid damage to the components and ultimate malfunction of the steamer. (See WATER QUALITY in this manual).

HEATER ELEMENTS DO NOT COME ON
When the steamer is turned ON and heater elements do not activate, and the READY light does not come on, then the contactors may be burned out. If a considerable amount of “chattering” of contactors has been previously experienced, then the thermostat bulb may be coated with sealant and unable to sense water temperature in the boiler accurately, and therefore unable to control the contactors.

1. Replace contactors.
2. Unscrew the thermostat bulb, clean off sealants, and screw the thermostat bulb back in.

This problem may be an indication of inadequate water quality and is not covered under warranty. Have water quality analyzed and corrected immediately to avoid complete malfunction of the steamer.
UNIT SHUTS DOWN WHILE IN OPERATION
The pressure switch has been activated due to the 5 psi (34 kPa) pressure in the generator tank. Pressure in the generator tank is caused by plugged steam jet tubes or steam diverters due to scale or poor water conditions. Steam jet tubes/steam diverters will have to be cleaned or replaced.
