VSX SERIES STEAMERS - OPERATION

Electrically Powered Steam Boiler
Open the cabinet door and turn main power switch
ON. The red light will illuminate, water will begin
filling the boiler and the blowdown solenoid valve
will close. The boiler should fill, in 4 to11 minutes.
Observe water level gauge glass to verify that water
is in boiler and that the level in the gauge glass is
about half full. Both valves on gauge glass
assembly must be open to fill the gauge. Older
models equipped with a manual “ball” type
blowdown valve must be closed for the boiler to fill.
If the water level in the boiler has reached the
minimum level, the magnetic contactors will close,
the heaters will energize and begin to heat the water
in the boiler. After approximately 15 minutes, steam
should be present for cooking product. Observe that
the boiler pressure gauge indicates steam pressure
of 11-13 psi.
Direct Steam Powered Cooker
1. Open the cabinet door and turn main power
switch ON.
A. The red light on the switch will illuminate.
B. If steam pressure is above the minimum
setting on the cooking compartment
pressure switch then the switch will close,
ready light will come ON and power to the
other controls will be supplied.
C. Observe that the steam pressure gauge in
the cabinet base, indicates 10-12 psi.
2. Steamer is ready to cook product.
Regenerated Steam Powered Boiler
1. Open the cabinet door and turn main power
switch ON. The pilot light will illuminate, water
will begin filling the boiler and the blowdown
solenoid valve will close. Models equipped with
a manual “ball type” blowdown valve need to
be closed for the boiler to fill. The boiler should
fill, in approximately 15 minutes. Observe
water level gauge glass to verify that water is in
boiler and that the level in the gauge glass is
about half full.
Both valves on the gauge glass assembly must
be open to fill the gauge. When the water
reaches the minimum level, the steam solenoid
valve will open, allowing steam to enter the
steam coil in the heat exchanger tank and
begin heating the water. After approximately 20
minutes, a sufficient amount of pressurized
steam should be present for cooking product.
BOILER BLOWDOWN AND
STEAMER SHUT OFF
Turn the steamer off at least once daily and blow
down the boiler to remove sediments, scalants and
lime build-up in the boiler. Always blowdown the
boiler when it is under maximum pressure and no
steam is being used.
1.
Automatic blowdown.
A. Newer Models
- Open the cabinet door
and turn main power switch OFF. The
switches’ red light will go out, the
blowdown/drain solenoid valve will be de-
energized and the boiler will begin to
drain. The cold water condenser solenoid
will continue to operate, as needed, to
condense steam and to cool the water
going into the drain.
B. Older Models
- Turn power switch OFF
and depress blowdown timer button.
Blowdown timer will operate for 4 minutes.
At the end of blowdown, turn fill switch to
ON and allow boiler to fill.
2.
Manual blowdown.
A. All Models
- Turn power switch OFF. Open
blowdown valve located on the bottom
front of the cabinet base. After the boiler
has completely drained, close blowdown
valve and turn fill switch to ON and allow
boiler to fill.
