INSTALLATION
NOTE: When placing the unit, make sure
to provide at least 3 inches of space on
all sides of the unit.
1. Remove unit and all packing materials
from shipping carton.
2. The unit should come with the items
listed below:
• Owner’s Manual
• Authorized Service Agency Directory
• Inlet Hose Assembly (DFW/DFWT/
DFWF-200/250 only).
NOTE: If any parts are missing or dam-
aged, contact Antunes Technical Service
IMMEDIATELY at 1-877-392-7854 or
1-630-784-1000.
3. Remove all packing materials and
protective coverings from the unit.
4. Remove and wash the Pan, Trivet, and
Diffuser in soap and water. Rinse with
clean water and allow to air dry.
NOTE: The steam generator surface
(Figure 6) will have a white coating of
artificial lime deposits. This coating is
necessary for steaming characteristics.
5. Wipe all surfaces of the unit with a
hot damp cloth.
NOTE: Do NOT use a dripping wet cloth.
Wring out before use.
6. Re-install Pan, Trivet, and Pan Diffuser.
When placing the unit into service, pay atten-
tion to the following guidelines.
• Make sure to provide at least 3 inches
of space on all aides of the unit.
• Make sure the power switch is off and
the unit is at room temperature before
plugging in the power cord.
• Do not block or cover any openings
on the unit.
• Do not immerse the power cord or
plug in water.
• Keep the power cord away from
heated surfaces.
• Do not allow the power cord to hang
over edge of table or counter.
Plug the power cord into the appropriate
power outlet. Refer to the specification
plate for the proper voltage.
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.
MODELS DFW/DFWT-100/150
The DFW/DFWT-100/150 models have a self-
contained water tank. To fill the tank:
1. Open the tank cover 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.
MODELS DFW/DFWT/DFWF-200/250
The DFW/DFWT/DFWF-200/250 models require
a direct cold water hookup. A water inlet hose
and strainer assembly (Figure 1) 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.
1. With the power off, place the unit on a
sturdy, level surface.
2. Ensure the line voltage corresponds to
the stated voltage on the specification
label and power cord warning tag.
3. Connect the unit to the power supply.
3. Turn the water valve on.
4. Over a bucket, press and hold
the white plastic tip on the Quick
Disconnect Insert (Figure 1) 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. Adjust the pres-
sure 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.
6. Push the Quick Disconnect Insert into
the fitting at the rear of the unit until
it clicks into place (Figure 1).

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).
