Cleaning The Boiling Tank; Changing The Post Filter - Pure Water A-12 Owner's Manual

B. CLEANING THE BOILING TANK
CAUTION: UNDER NO CIRCUMSTANCES SHOULD THE CLEANING SOLUTION BE
HEATED AND RUN THROUGH A STEAM STERILIZATION OR DISTILLATION CYCLE.
USE THE FOLLOWING PROCEDURES FOR CLEANING THE A-12:
a) Open the faucet on the sink and remove enough water to restart the unit. This will be
evident because the fan will turn on. Open the top cover and move the function switch to
the CLEAN position. At this time the fan will stop. Carefully feel the boiling tank lid and
check the temperature of the unit. If it is hot, wait at least 30 minutes for the unit to cool.
b) After the unit is cool, remove the boiling tank lid.
c) Add Lumen, following the directions on the package. Mix well, and pour into the boiling
tank.
d) Add additional water using a jar or pitcher until the water level inside the boiling tank is
above the scale line. CAUTION: Do not overfill.
e) Let the solution stand overnight.
f) After the scale has softened, turn the main power switch OFF. This will allow the boiling
tank to drain. Once the boiling tank has drained, turn the main power switch ON and
allow the boiling tank to refill. Turn the power off again, repeat this step several times to
flush the boiling tank of cleaning solution and scale.
g) Return the function switch to the DISTILL position. The unit is now ready for normal
operation.
C. CHANGING THE POST FILTER
a) Turn the main power switch OFF and open the faucet at the sink to bleed the line of
pressure. Close the faucet.
b) Have a bucket available to catch any excess water in the line. Remove the filter by
releasing the fittings on each end. Use care when removing the filter because you will need
to reuse the fittings. Push in on the grey ring in the fitting, while pulling the tube out with
the other hand.
c) Remove the two fittings from the end of the filter (see figure 6). Wrap the threads of each
fitting with new Teflon tape, and install in the new filter cartridge. Tighten securely.
d) Connect the inlet side of the filter to the waterline.
e) Using a bucket, hold the filter outlet over the bucket. Turn the main power switch ON and
allow water to flush the carbon fines out of the new filter. If the storage tank is low,
depress the pump switch and flush the filter.
f) Now that the filter is flushed, reconnect the outlet side of the filter to the waterline.
