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.
Temperature of condensate water flowing through the drain is controlled by the Thermostatic Cooling Valve (TCV)
located inside the controls compartment on the right side of the unit. The valve has been factory set to keep
condensate water flowing into the drain at or below 140°F. Depending on local plumbing code requirements, this setting
may be changed to obtain a different maximum drainage temperature. Refer to next section Performance Check for
instructions to set the (TCV).

onditioning
It is important that the water supplied to the generator 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 steam generator. Due
to the temperatures in the steam generator, 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 may bridge across
the probe insulator from the metal extension which senses the water level in the steam generator shell. Once this scale
becomes wet, the water level control is unable to maintain the proper water level in the steam generator.
STRAINERS and FILTERS will NOT remove minerals from the water.
