ELECTRIC COUNTER CONVECTION STEAMER INSTALLATION
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 e󰀩ciency. 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 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
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.
WARNING
Plumbing connections must comply with applicable sanitary, safety and plumbing codes.
