Stores that have harder water in their areas, may experience scale build-up in their water tubes,
thus clogging the tube and preventing water from being dispensed into the steaming chamber. If the
tube needs to be replaced, this sheet will illustrate how to replace the water tube.

First, turn off and unplug steamer. Let
steamer cool down. To remove the rear
cover plate that shields the water tube,
use a Philips
head screw
driver to remove
the two screws,
Next, take off
the rear cover
plate to access
the water tube.

Finally, re-install the rear cover plate.
Turn on unit and begin a water cycle to
check for leaking at the water valve. If
leaking occurs
at the back
panel of the
steamer, turn
off unit and
repeat Step 5.

To insert the new tube, first insert the top
end through the hole that leads to the
platen. The tube will fit through the
insulating
bushing.

To pull the tube out from the water valve,
push in the grey disk on the water valve
and then slowly slide the tube from the
water valve.

Grey disk
is here -
at end of
valve

Push the other end of the tube into the
water valve. Ensure that you feel it click
into place. Gently tug on the water tube to
check if it is
secure. If the
tube slides
out, re-install
the tube. If
tube is improp-
erly installed,
water will leak
at this point.

Using pliers, gently pull
the tube out from the
platen. You may need to
softly rock it back and
forth. Replace the black
insulating bushing if the
original bushing pulled
out with the water tube.
All units must have a
bushing installed. To re-
install the bushing,
lubricate it with water
and push it back into
the opening. CAUTION:
Platen must be cool.
