GENERAL INFORMATION
ALL MODELS
When the
OPERATE
button is pressed, power
is supplied to the water pump (Water Tank
models) or solenoid valve (Direct Water
Hookup models). The pump/solenoid oper-
ates and water sprays onto the heated steam
generator. The water flashes immediately into
steam and steams the product.
TIMER MODELS DFW/DFWT/DFWF–
150/250 EXCEPT DFWF-250 WITH
MFG. NO. 9100147
On Timer Models, one of two operational modes
can be used: Single Shot or Timed Cycle.
Single Shot
The
OPERATE
button is pressed and released
to initiate a single steam shot. The Control
Board applies power to the water pump/sole-
noid and a shot of steam occurs.
Timed Cycle
The control is used to set the desired steam
time (up to 99 minutes, 59 seconds). When
the
START/STOP
button (Figure 3) is pressed,
the Control Board applies power to the water
pump/solenoid at regular intervals for the
duration of the displayed cycle time. The dis-
play counts down to zero, sounds an audible
signal when the cycle is complete, and then
reverts back to the original programmed cycle
time. The unit is ready for the next cycle when
the green ready light is on.
IMPORTANT: Timer Models are factory pro-
grammed for the following recommended
settings:
•
Total Cycle Time = [15.00] (15 min-
utes)
(Range: 3 sec. to 99 mins 59 secs)
•
Shot Interval Time (SHO) = [00:20] (20
seconds)
(Range: 3 secs to 5 mins 59 secs). 20
seconds is recommended.
•
Water Volume (H2O) =
DFW/DFWT/DFWF-250 - [0_50]
DFW/DFWT-150 - [0_80]
(Range: 0.10 seconds to 2.50)
The above settings convert approximately 3/4
oz. (25 milliliters) of water into to steam every
20 seconds for 15 minutes. To change any of
these settings see the appropriate Operating
Instructions for your specific unit.
