Calcium Hypochlorite by the nature of its manufacture, contains a small amount of calcium carbonate. Proper

water balance will minimize the buildup of calcium carbonate solids in the Pulsar® 3 Chlorinator, however,

periodic cleaning of chlorinator components is normal and recommended. Th e following is a list of the parts to be

cleaned and the proper procedures to do so.

Cleaning PULSAR® 3 Chlorinator with PULSAR® Plus Acid Cleaner 50

Inspection: Th e solids build-up and cleaning frequency required for the unit will depend on the amount of

Briquettes used and the pool water chemistry. Described below is the easiest way to remove solids and minor scale

buildup using the PULSAR® Plus Acid Cleaner 50.

WARNING

Do NOT use Muriatic Acid to perform the following procedures.

Chlorine gas may evolve causing serious injury or possible death.

Maintenance Procedure Steps:

1. Close the inlet and outlet shutoﬀ valves to the chlorinator.

2. Lift the Briquette Tank oﬀ of the Spray Manifold Section and Discharge Tank and pour the contents into a clean

dry bucket. Be sure to remove all pieces of briquettes or tablets. If necessary, rinse any heavy solids buildup from

the tank before proceeding.

3. Remove briquette grid and place in black tub (provided with system). Fill with 1 gallon of water. Slowly pour ½

quart PULSAR® Plus Acid Cleaner 50 into tub and ½ quart PULSAR® Plus Acid Cleaner 50 into discharge tank.

Frequent agitation may be required to dissolve solids and scale. Allow acid to dissolve solids and scale, evident

by the foaming action. After 5 to 10 minutes, check for presence of scale on grid. If necessary, add additional

PULSAR® Plus Acid Cleaner 50 to dissolve any remaining scale or scrape with putty knife.

4. Pour the solution from tub into the discharge tank. Dispose of scale with backwash from ﬁ lter.

5. Place the Briquette grid back into bottom of hopper.

Rinse the Briquette grid thoroughly with water and

open the inlet-shutoﬀ valve to allow the spray to

rinse the grid from the bottom. Th e solution from the

Discharge tank will clean the discharge valve, tubing

and venturi when system is restarted.

6. Pour Pulsar® Plus Briquettes from bucket back into

Briquette Tank. Resume operation.

7. Open inlet and outlet shut oﬀ valves to the chlorinator.

NOTE: To increase the period between Grid cleanings,

allow Briquette Tank to completely empty once a week.
