MONTHLY MAINTENANCE
CLEAN SPRAY TUBE AND STEAM
GENERATOR
The Deluxe Food Warmer utilizes an open
Steam Generator. Water sprayed onto the
generator surface flashes into steam imme-
diately, but the minerals in the water do not
steam. They stay on the generator surface. A
small amount of calcium/mineral deposits are
needed for proper operation, but a buildup
of excessive calcium/mineral deposits causes
poor steaming efficiency and excessive
moisture (wet steam), which will eventually
severely retard the steaming action.
1. Turn the power off, unplug the power
cord, and allow the unit to cool down
before proceeding.
2. Perform the Daily Cleaning, but do not
reassemble the unit.
3. Remove the spray tube (Figure 6) by
lifting the loose end and pulling it out
of the generator hole.
4. Slide the metal cover off of the spray
tube, take a paper clip and clear out
all of the tube’s holes.
5. Gently wash the tube under running
water to clear the deposits out of the
loose end. Reattach the cover onto
the tube.
NOTE: Do not bend the spray tube. Any
bends in the tube will result in permanent
damage.

NOTE: If deposits are still excessive and/
or difficult to remove, refer to Steps 1
through 6 below.
1. Pour delimer solution (not supplied)
onto the generator surface. Follow the
delimer manufacturer’s instructions for
proper mixture and use.
2. Using a sponge or a dry towel, remove
the delimer solution from the genera-
tor surface and then rinse the surface
with clean water.
To ensure proper steaming characteristics,
some calcium/mineral deposits must be pres-
ent on the generator surface. If, during clean-
ing, the surface does become free of calcium/
mineral deposits, add plain tap water to the
surface and allow it to boil off. If necessary,
repeat this process to formulate a thin coating
of calcium/mineral deposits.
In soft water areas. it may be necessary to
add a small amount of lime to the generator
surface to season it. This will ensure proper
steaming characteristics by producing a thin
coating of calcium/mineral deposits on the
Generator surface.
6. Use a scraper or spatula to remove the
excessive calcium/mineral buildup from
the generator surface (Figure 6).
7. Thoroughly wipe the generator with
a damp cloth to remove any loose
buildup and reassemble the unit.
Seasoning mixture consists of 3/4 ounces (25
ml/25 cc) baking soda, 3/4 ounces (25 ml/25
cc) lime mixed with 1 quart (950 ml/950 cc) of
water. Stir mixture and pour 1/4” deep onto
the hot Generator surface. After mixture is con-
verted to steam, the remaining loose powder
can be removed.
3. Plug the power cord into the appropri-
ate outlet.
4. Turn the power on and allow the unit
to warm up for approximately 30
minutes.
5. Push and release the
OPERATE
button
several times to purge any remaining
delimer residue from the generator
surface.
6. Turn the power off, reinstall all parts
and accessories, and return the unit to
service.
