2.0 INSTALLATION INSTRUCTIONS
This steamer was inspected before leaving the factory. The transportation company assumes full responsibility for safe delivery upon acceptance of the shipment. Immediately after unpacking the steamer, check for possible damage. If the steamer is found to be damaged after unpacking, 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" (915 mm) at the front of the steamer and 15" (381 mm) above the steamer.
LEVELLING AND ANCHORING
Using a spirit level or pan of water in the bottom of the steamer, adjust the levelling feet to level the steamer front-to-back and side-to-side.
Mark hole locations on the floor through the anchoring holes provided in the flanged adjustable feet. Remove the steamer and drill holes at marked locations on the floor. Insert proper anchoring devices.
Set steamer back in proper position. Install bolts through anchoring holes and into anchors to secure the steamer to the floor. Seal
bolts and flanged feet with Silastic. 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.
ELECTRICAL CONNECTION
WARNING: Electrical and grounding connections must comply with applicable portions of the national electrical code and/or other local electrical codes.

INSTALLATION AND OPERATION MANUAL AND PARTS LIST,
INSTALLATION INSTRUCTIONS (Continued)
WARNING: Disconnect the power supply to the appliance before cleaning or servicing.
Make electrical connection through the 1-1/8" (29 mm) diameter hole provided using 3/4" (19 mm) trade size conduit. Refer to the wiring diagram located inside the right side panel. Use 90°C minimum insulated wire.
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.
We recommend treated water feeding the boiler inlet supply, and untreated water feeding the cooling system inlet. Hook-ups are labelled on the back of the steamer.
ADJUSTMENT FOR HIGH ALTITUDE LOCATIONS
The steamer has been factory set so that when it is ON, and during the READY phase, it will maintain water temperature in the steam generator tank at approximately 205°F (96°C) (just below water boiling point). However, for high altitude locations, an authorized service agency must adjust the steamer to achieve this temperature.
ADJUSTMENT FOR DRAIN WATER TEMPERATURE
Cooling solenoid valves have been adjusted to yield drain temperatures of 140°F. This will vary depending on install location water supply temperature and pressure. A qualified service person should adjust the cooling solenoid valves should the drain temperature be other than desired. Refer to Section 7.0 Service on page 20 for adjustment instructions.

DRAIN CONNECTIONS
The drain connection must be 1" (25 mm) IPS down, preferably with one or two elbows only, maximum length 6 feet (1830 mm) and piped to an open gap type drain (Figure 1). Drain pipe should be either iron or copper. DO NOT use PVC pipe – PVC pipe may lose its rigidity or glue may fail.
CAUTION: To avoid injury or damage to the steamer, do not connect solidly to any drain connection.
FIGURE 1
WATER QUALITY
The water supply connected to the steam generator should meet the following guidelines: Failure to comply with water quality statement on page 4 may void the warranty. Water supplies vary from one location to another. Other factors affecting steam generation are
iron content, chlorides, and dissolved gasses. A local water treatment specialist should be consulted before installing any steam generating equipment.
Untreated water contains scale producing minerals which can precipitate onto the surfaces in the boiler. Due to the temperatures in the boiler, 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.
PART NUMBER 10223R1 7 2010-06-24
INSTALLATION AND OPERATION MANUAL AND PARTS LIST,
WATER QUALITY (Continued)
2. The water level probes become coated with scale. Scale will bridge across the probe insulator from the metal extension which senses the water level in the boiler shell. Once this scale becomes wet, the water level control is unable to maintain the proper water level in the boiler. 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 18.
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 NFPA Standard No. 96, Vapor Removal from Cooking Equipment, (latest edition).

START-UP TEST
WARNING: The steamer and its parts are hot. Use care when operating, cleaning or servicing the steamer. The cooking compartment contains live steam. Stay clear while opening the door.
Once the steamer is installed and all mechanical connections have been made, thoroughly test the steamer before operation.
1. Check that proper water, drain, and electrical connections have been made.
2. Turn main power switch ON. After approximately 15 minutes, the READY light should come on, indicating that the water temperature is 205°F (96°C).
3. When the READY light comes on, set the timer at 5 minutes. With door open, observe that no steam is entering the compartment and the COOKING light is OFF.
4. Close compartment door. The COOKING light should now be lit and steam should be heard entering the compartment after about 45 seconds (5 minutes if boiler is empty).
5. Check drain line to ensure that water from the cold water condenser is flowing through the drain line.
6. Open compartment door and observe that steam supply to the chamber is cut off (READY light should again come on and COOKING light goes off).
7. Close compartment door and let cooking cycle finish. When the timer returns to the “O” position, a buzzer will sound, signalling the end of the cooking cycle. To silence the buzzer, turn the dial timer to OFF.
8. Complete the above steps for each cooking compartment.
9. To shut the steamer down, turn the main power switch OFF and leave the compartment doors slightly open to allow the inside to dry out.

3.0 OPERATION INSTRUCTIONS (Continued) BEFORE FIRST USE
Clean the protective oils from all surfaces of the steamer. Use a non-corrosive, grease dissolving commercial cleaner, following manufacturer’s directions. Rinse thoroughly and wipe dry with a soft clean cloth.
PREHEAT
Turn the main power switch ON. When the READY light comes on, set the timer to 1 minute to preheat the compartment. This should be done when the steamer is first used for the day or whenever the chamber is cold. The door should be closed during the preheat cycle. The COOKING light will be lit. When the buzzer sounds, set the timer to the OFF position. The steamer is now ready to cook.
COOK
With compartment preheated and READY light ON, place pans of food into the compartment and close the door.
Set timer to desired cooking time. (The cooking cycle may be interrupted at any time by opening the door. To resume operation, close the door.) Steam will flow into the compartment and the COOKING light will be lit.
At the end of the cooking cycle, the buzzer will sound, the COOKING light will go off and steam supply to the compartment will cease. Turn the timer to the OFF position to silence the buzzer.
CONSTANT STEAM COOKING - This mode will give continuous steam to the cooking chamber until the operator turns power OFF to the steamer. .
When cooking is complete, or not in use, the constant steam cooking feature should be shut off. This prevents the boiler from running unnecessarily. This will help conserve water, and will reduce boiler maintenance.
SHUTDOWN
Turn main power switch OFF. The boiler will automatically blow down. Leave the compartment door open to allow the inside to dry out. For an extended shutdown, turn the main power switch OFF; turn power and water supply OFF.
Drain the boiler after each day’s use to flush out minerals and minimize scale build-up. The boiler drains automatically for approximately 4 - 6 minutes after the main power switch is turned off.

COOKING HINTS
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.
Preparation
Prepare vegetables, fruits, meats, seafood, and poultry normally by cleaning, separating, cutting, removing stems, etc. Cook root vegetables in a perforated pan. Other vegetables may be cooked in a perforated pan unless juices are being saved. Liquids can be collected in a solid 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 in their own juice. Meats and poultry are cooked in solid pans to preserve their juice or return broth.
Canned foods can be heated in their opened cans (cans placed in solid pans), or the contents may be poured into solid pans. DO NOT place unopened cans in the steamer.
Frozen Food Items
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 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.
