Water Quality
The water supply connected to this steamer should contain no more than 2.0 grains of hardness per gallon with 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 which 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 eciency. This can produce
hot spots on the heating elements and result in premature failure.
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 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 lters will NOT remove minerals from the water.
Refer to REMOVAL OF LIME SCALE DEPOSITS, page 14.
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.
INSTALLATION
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.

Steam Cooking
Your steamer eciently 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 ecient 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 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. 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 1/3 size x 2.5” deep solid pans) or the contents may be poured into solid pans.
Acceptable Pan Sizes
The steamer accommodates 1/3 size x 2.5” pans, solid or perforated.

Maintenance
WARNING
Disconnect the power supply to the appliance before cleaning or servicing.
Cold Water Condenser
The steamer is equipped with a cold water condenser in the rear of the cooking compartment 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 delimed once a month, or more often if necessary.
Should your steamer develop a heavy buildup of lime scale deposits, use CLR.
Before beginning deliming procedures, ensure that water is not overowing into the cooking compartment.
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.

Troubleshooting
Water Flows Into Drain During Shutdown
When steamer is shut down and cold water is running continuously into the open drain, either or both solenoid valves did
not close when steamer was turned o.
1. Disassemble solenoid valve(s) and examine for scale or foreign particles lodged in diaphragm or core tube.
2. Clean valve(s) thoroughly and reassemble or replace valve(s).
Water Overflows Into Cooking Compartment
When steamer is rst turned on for the day, and the following conditions occur:
- READY light does not come on after about 5 minutes,
- Water begins to overow into cooking compartment,
- Water ll 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 ll 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 ll (solenoid) valve to shut o the water.
As a temporary solution, with power OFF, unscrew probes, check visually, and clean or chip o scalant. 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).
