Inspection:The solids build-up and cleaning frequency
required for the unit will depend on the amount of
tablets used and the pool water chemistry. Described
below is the easiest way to remove solids and minor
scale buildup using dilute Muriatic Acid.
WARNING
Perform cleaning operation in a well ventilated area.
Chlorine gas may evolve causing serious injury or
possible death. Use proper protective equipment per
MSDS when handling chemicals. Use caution handling
feeder parts and solution as they contain chlorine that
can bleach clothing or cause injury.
Maintenance Procedure Steps
1. Note the inlet flow setting. Close the inlet and
outlet shutoff valves to the Feeder.
2. Remove tablet cartridges from the hopper and
empty tablets into a clean dry bucket. Be sure to
remove all pieces of tablets. If necessary, rinse
any heavy solids buildup from the cartridges into
a clean bucket before proceeding. Remove hopper
from base and place on a clean surface.
Note: Always add acid to water. Never add water to
acid as splattering will occur resulting in possible
injury.
3. Fill a small plastic bucket (4-6” diameter) with
1 pint of water. Slowly pour 3 ounces of Muriatic
acid into the bucket. Place one cartridge (grid
down) at a time in the bucket to dissolve scale on
the cartridge grid. Remove when the scale on the
grid is gone and rinse with water. Repeat procedure
for all scaled cartridges using the same acid
solution.
4. Lift the dissolving cup out of the way pouring the
contents into the base carefully. Rinse off and soak
in dilute acid solution in a bucket if necessary to
remove scale.
5. Pour the solution from the discharge tank slowly
into the bucket used in step 2 for rinsing the
cartridges and add 1 gallon of fresh water to
discharge tank.
6. Add 1 cup of Muriatic acid to the discharge tank to
dissolve the scale. Let sit until scale is gone.
7. Pour the solution from bucket used in Step 3 into
the discharge tank. Rinse out bucket with water
and store for future use.
8. Place the Tablet cartridges back into the hopper.
The solution from the Discharge tank will clean
the discharge valve, tubing and venturi (if present)
when system is restarted.
9. Replace the dissolving cup and put the hopper back
on the base.
10. Open inlet and outlet shut off valves to the Feeder.
11. Place the tablets from the bucket back into
Cartridge(s). Adjust inlet flow to desired setting.
12. Dispose of chlorinated solution from steps 2 & 5 in
skimmer, gutter or pool (when not in use).
