MAINTENANCE (continued)
CLEANING THE WATER INLET TUBE
Sometimes when cleaning the Steam Generator, small
particles may be pushed into the Water Inlet Tube,
causing it to become clogged.
In a clogged state, the unit is unable to spray water into
the Steam Generator. Follow these steps to clean the
Water Inlet Tube and to restore the unit to proper oper-
ating condition:
1. With the unit heated, insert a straightened paper
clip SLIGHTLY into the Water Inlet Tube opening
(Figure 1) and rotate in a circular motion.
NOTE: Do NOT shove the paper clip into the tube,
otherwise you may further clog the tube.
2. After cleaning the Water Inlet Tube, remove the
paper clip and cycle the unit several times to flush
out any particles. If the water sprays, the unit is
ready for use. If the water does NOT spray, follow
Steps 3 through 5.
3. Set the adjustable Water Pressure Regulator
between 20–25 psi.
4. Cycle the unit several times to flush out any
particles.
5. Once the water sprays, set the water pressure
back to 7–9 psi.
NOTE: Cycle the Steamer several times while
adjusting the water pressure regulator knob until
the water pressure gauge reads between 7–9 psi.
TESTING THE STS-200 FOR WEIGHING ACCURACY
1. Turn the unit on and allow it to warm up for 30
minutes.
2. Ensure nothing is on the Steamer/Scale surface
and that the Top Cover is seated correctly.
3. Press the Zero (on) button once. The display
should now read “0.0”.
4. Place the certified 1-pound (16 ounce) calibration
weight in the center of the scale surface.
5. The display should register 15.9 to 16.1 ounces
(452.67 to 458.36 grams). If it does, the Steamer/
Scale is weighing properly, and does not need
calibrating.
If the unit does not register 15.9, 16.0, or 16.1
ounces (452.67 to 458.36 grams), you must cali-
brate the scale according to the Operating section
of this manual.
5. Use a stainless steel wire brush to loosen and
remove excessive deposits from the Steam
6. Pour Delimer/Scale Remover (HCS) so that it
follow the delimer manufacturer’s directions for
proper mixture and use; it must be safe to be
used on aluminum. Wait one hour.
7. Remove the Delimer/Scale Remover (HCS) from
the Steam Generator and rinse with clear water to
remove all remaining traces.
General Detergent Cleaner (HCS) and water,
then rinse in clear water and allow to air dry.
9. Clean unit surface with a hot, clean, damp cloth
(not dripping wet) and wipe dry. Re-install all
parts.
IMPORTANT: To ensure proper steaming character-
istics, some mineral deposits must be present on
the Steam Generator surface. If during cleaning, the
surface does become free of mineral deposits (bare
aluminum), add plain tap water to the surface and
allow it to boil off.
IMPORTANT: In soft water areas, it may be neces-
sary to add a small amount of lime to the Steam
Generator surface to “season” it.
This will ensure proper steaming characteristics by
producing a thin coating of mineral deposits on the
surface. To season the Steam Generator, Mix 1 tea-
spoon of Baking Soda with 3 ounces of water.
Pour the seasoning mixture onto the hot Steam
Generator. After mixture is converted to steam, the
remaining loose powder can be removed.
10. Plug the power cord into the appropriate outlet
and connect the water line. Turn the Steamer/
Scale on, allow the unit to preheat for 30 minutes,
and zero the unit.
11. If the Water Inlet Tube becomes clogged so that
water cannot flow onto the Steam Generator, refer
to the Cleaning The Water Inlet Tube section of
this manual.
