PLUMBING CONNECTIONS (Continued)
COLD WATER 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 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.
WATER CONDITIONING
It is important that the water supply connected to this steamer be softened to no more than 2.0
grains of hardness and have a pH of 6 to 7.5. This degree of hardness can be easily obtained
with the use of a properly maintained water softener. The use of a water meter will determine
the water consumption and when the water softener needs regeneration or recharging. Failure
to comply with these water condition standards may void the warranty.
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. 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.
STRAINERS and FILTERS will NOT remove minerals from the water.
