c. Remove six (6) hex head screws securing tank
cleanout plate and remove plate.
d.
Remove lime, scale, or sediment using care not to
damage the glass lining.
e.
Inspect cleanout plate gasket, if new gasket is
required, see the replacement parts list for item
number.
f. Install cleanout plate. Be sure to draw plate up tight
by tightening screws securely.
g. Replace outer jacket cover plate.
h. In some water areas the sediment might not be
removed by this method and may result in the
water heater making rumbling or boiling noises. To
dissolve and remove these more stubborn mineral
deposits, UN•LIME Professional Delimer should be
used.
DELIMING USING FLO-JUG METHOD
UN•LIME in the 5 gallon size is recommended for
deliming this water heater. UN•LIME with the necessary
hoses and fittings to delime your heater is also available
as a kit: Up-N-Down Transfer Kit. Contact your local
dealer, distributor or water heater manufacturer.
PREPARE THE WATER HEATER
To delime the water heater using the Flo-jug method, first
prepare the heater for deliming.
PREPARE THE UP-N-DOWN TRANSFER KIT
The next step is the preparation on the Up-N-Down
Transfer Kit, if you have not already done so:
1.
With the 5 gallon Up-N-Down container in the vertical
position, unscrew the plastic vent cap in the handle
and pierce the plastic membrane over the vent boss
under the cap to allow the container to vent.
Note:
If your container does not have the vent cap and
vent boss, drill a 3/16” (4.76 mm) hole in the handle.
When you have finished deliming you will be able to
plug this drilled vent with the stainless steel screw that
is supplied with the kit.
2.
Remove the container’s cap and cut plastic membrane
located in the 3/4” IPT opening in cap. Take care to not
damage the threads.
3.
Find the 3/4” male adapter, apply teflon tape to the
threaded end and screw it into the 3/4” IPT opening in
the cap.
4.
Put cap with male adapter back on the container and
slide 3/4” hose over end of male adapter and fasten in
place using hose clamp provided.
DELIME USING FLO-JUG METHOD
1.
Slide the hose clamp over end of hose and slide
hose over the male adapter in the water heater drain
opening and secure in place using hose clamp.
2.
Lift container to the “Pour” Position being careful to
keep the vent in the handle above the liquid level and
pour the UN•LIME into the heater.
3.
Lower container, you may have to place the container
on its empty carton to prevent the UN•LIME from
flowing back into the container.
4.
Let UN•LIME remain in the heater for 5 minutes and
then lower the container to the “Drain” Position.
5.
Deliming activity is indicated by foaming on the
surface of the UN•LIME. If there is deliming activity,
repeat steps 6 thru 8.
FIGURE 26. DELIMING KIT CONFIGURATION
Normally, lime removal will be completed within one hour.
Severe build-up of lime may take longer than an hour to
complete descaling.
Note:
To check UN•LIME for continued use, place some
scale or white chalk in a glass with a small amount of
UN•LIME. If the material is vigorously dissolved by the
UN•LIME, it can be reused; if not, the UN•LIME should be
replaced.
If the temperature-pressure relief valve on the appliance
weeps or discharges periodically, this may be due to
thermal expansion. You may have a check valve installed
in the water line or a water meter with a check valve.
Consult your local water supplier or service agency for
further information. Do not plug the temperature-pressure
relief valve.
