MODELS DFW/DFWT/DFWF-200/250
These models require a direct cold water hookup. A
Water Inlet Hose and Strainer Assembly (Figure 4) is
supplied.
NOTE: Incoming water is controlled by a normally
closed (NC) solenoid valve located inside the
Steamer’s electrical housing.
1. Turn off the water valve (not supplied) that
provides water to the unit (Figure 4).
2. Connect the 1/4” (6.5 mm) I.D. Flexible Tubing to
the outlet side of the Water Pressure Regulator
and secure using the worm clamp (Figure 4).
NOTE: A Water Pressure Regulator must first be
installed as shown in Figure 4. 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 4) until a
good, steady water flow is noted (this will purge all
air out of the line).
5. Release and note the pressure on the Water
Pressure Regulator gauge. It should read 20-25
psi. If it reads more or less, adjust the pressure
by pulling the black knob upwards and turning
it clockwise to increase or counter-clockwise to
decrease the water pressure. Push the knob
down to lock it in place.
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.
5. Push the Quick Disconnect Insert into the fitting at
the rear of the unit until it clicks into place
(Figure 4).
CAUTION
Water pressure must not exceed 30 psi (2.1 kg/
cm
2
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/
cm
2
or 138–172 kPa).
