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 compart-
ment. Steam leakage at the door may indicate a plugged
or improper 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 hard-
ness and have a pH of 6 to 7.5. This degree of hardness
can be easily obtained with the use of a properly main-
tained water softener. The use of a water meter eill deter-
mine 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 surface in the boiler. Due to the
temperatures in the boiler, the minerals can bake onto the
surface and components. This can result in early compo-
nent failure and reduced product life.
Water level probes become coated with scale. Scale will
bridge across the probe insulator from the metal exten-
sion 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. STRAIN-
ERS and FILTERS will NOT remove minerals from the
water.
INSTALLATION

PERFORMANCE CHECK

Once the steamer is installed and all mechanical connec-
tions have been made, thoroughly test the steamer before
operation.
1. Check that proper water, drain, electrical and gas
connections have been made.
2. Turn main power switch ON. After approximately 19
minutes the READY light should come on, indicating
that the water temperature is 205°F (97°C).
3. Check that IGNITION light comes on and cycles ON
and OFF.
4. When the READY light comes on, set timer to the
5 MINUTE position. With door open, observe that
no steam is entering the compartment and that the
COOKING light is OFF.
5. Close the compartment door. The COOKING light
should now be ON and steam should be heard enter-
ing the compartment after about 45 seconds.
6. Ensure that water from cold water condenser is flow-
ing through the drain line.
7. Open compartment door and observe that steam sup-
ply to chamber is cut off. READY light should come
ON again as COOKING light goes OFF.
8. Close compartment door and let cooking cycle fin-
ish. When the timer returns to 0 position, a buzzer will
sound signaling the end of the cooking cycle. Buzzer
must be manually turned off by setting the timer to its
OFF position.
