PLUMBING
DFW models are designed to use cold tap
water. Distilled water may be used to reduce
calcium/mineral deposit buildup and reduce
maintenance costs.
DFW-150 MODELS
The DFW-150 models have a self-contained
water tank. To fill the tank:
1. Open the tank cover (Figure 1) on the
top of the unit.
NOTE: Make sure the filter inside the tank
is installed properly.
2. Pour in cold tap water. The tank will
hold approximately 3 quarts (2.81
liters). Do not overfill the tank.
3. Close the tank cover.
DFW-250 MODELS
The DFW-250 models require a direct cold
water hookup. A water inlet hose and strainer
assembly (Figure 2) is supplied.
Incoming water is controlled by a normally
closed solenoid valve located inside the
steamer’s electrical housing.
1. Turn off the water valve (not supplied)
that provides water to the unit.
2. Connect the 1/4" (6.5 mm) ID flexible
tubing to the outlet side of the water
pressure regulator and secure using
the worm clamp.
NOTE: A Water Pressure Regulator must
be installed. Failure to do so will result
in poor steaming and possible flooding.
For a single steamer, use Water Pressure
Regulator P/N 7000314. For two adjacent
steamers, use Water Pressure Regulator
P/N 7000235.
3. Turn the water valve on.
4. Over a bucket, press and hold
the white plastic tip on the Quick
Disconnect Insert (Figure 2) until a
good, steady water flow is noted (this
will purge all air out of the line).
5. Release the plastic tip and check
the pressure on the Water Pressure
Regulator. It should read 20 psi.
a.) If it reads less, increase the water
pressure by pulling the black knob up
and turning it clockwise.
b.) If it reads more, decrease the water
pressure by pulling the black knob up
and turning it counter clockwise.
NOTE: When adjusting the knob, you must
relieve the existing pressure by pressing
the plastic tip on the Quick Disconnect
Insert for 3 seconds. This allows the newly
set pressure to register on the gauge.
Repeat this until the gauge reads 20–25
psi.
6. Once the regulator reads 20 psi, push
the black knob down to lock it in
place.
7. Push the Quick Disconnect Insert into
the fitting at the rear of the unit until
it clicks (Figure 2).

CAUTION
Water pressure must not exceed 30 psi (2.1
kg/cm2 or 207 kPa). Higher water pressures
may cause poor performance or flooding.
To reduce water pressure, install a water
pressure regulator, and set water pressure to
20–25 psi (1.4–1.7 kg/cm2 or 138–172 kPa).
