General Principles of Operation
e three main components of the Pulsar® 3 Chlorinator
are (from top to bottom) the briquette tank, the manifold
e water from the
pool enters the Pulsar® 3 Chlorinator via the emergency
shuto e water then splits to feed the spray
e spray
manifold then distributes the water onto the briquette bed
e chlorinated solution
falls into the discharge tank and is discharged into the
e amount of chlorine
discharged is determined by the ORP controller or the
Timer/Solenoid Assembly. Inlet water pressure of 17 to 45
psi is required to provide sucient flow into the Pulsar® 3.
ese pressures will result in an inlet flow of 1.6
gallons/minute. e Pulsar® 3 feed rate settings referred to
in the Pulsar System Owners manual are calibrated for this
flow rate. Flow out of the Pulsar® 3 Chlorinator requires
vacuum to properly evacuate the discharge tank. A minimum
outlet flow-rate of 1.7 gallons/minute ensures that the flow
out of the Pulsar® 3 exceeds the flow in. Once the Pulsar® 3
has been installed the outlet flow can be measured by
watching the level in the bottom tank. If the level is
rising as the feeder is running, there is insucient
flow out.

Pre Start-Up Checklist
Following the procedure outlined below will ensure a smooth start-up of the Pulsar 3 Chlorinator. For
seasonal operation, perform this procedure each spring.
IMPORTANT!!
Do NOT put Pulsar Plus Briquettes in the chlorinator during the start-up operation
Inlet Water Flow
e inlet water flow system is designed to provide a steady side-stream of clean filtered pool water to the
chlorinator.
1. Switch on the pool recirculation system and open all valves to the chlorinator.
2. Check the flow indicator (if present) of the Pulsar system to see that water is flowing into the
chlorinator
3. Check to see that the three nozzles are
spraying water onto the Briquette-Tank grid
and water is flowing from Solids Removal
Manifold.
4. Check all lines leading to the Chlorinator
for leaks. hand tighten all fittings if any leaks
are found.
Outlet Water Flow
e float on the Discharge Valve rises with
the water level and allows the pump suction
to draw the chlorinated water into the pool's
recirculation system as the Discharge Tank fills
with water. When the water level drops, the
float falls, shutting o e Discharge
Valve also contains a check valve to prevent
pool water from backing up into the Discharge
Tank. Use the following procedure to ensure
that the outlet water flow system is operating
properly.
1. With the briquette hopper and deflection
plate of the chlorinator temporarily out
of the way, fill the Discharge Tank with
sucient water to open the Discharge Valve
- use a hose or pail.
2. e float should rise, opening the Discharge
Valve, allowing water to be drawn out by
the Pulsar evacuation system (or venturi on
2" or less piping).
3. Check the system for leaks. If small air
bubbles are visibly moving, there may be
an air leak. Tighten the connections and
make sure the tubing is properly installed in
the fittings. (NOTE: Air bubbles near the
Pulsar 3 Chlorinator body that do not move
are normal and do not indicate leaks.)
4. Check to see that water is flowing through
both nozzles of the solids removal system.
5. Check for air leaks after the Discharge
Valve closes.

After completing the PRE-START-UP CHECKLIST, and establishing that all components of the chlorinator are
operating properly, your PULSAR® 3 Chlorinator is ready for start-up. Routine maintenance of the PULSAR®
3 Chlorinator is minimized when proper pool water balance is maintained. Maintain pool water chemistry as
follows:
Total Alkalinity 60-80ppm
Calcium Hardness 200-1800ppm
pH 7.2-7.6
Adherence to these recommendations at all times will ensure the most effective and economical performance from
the PULSAR® 3 Chlorinator.
NOTE: e use of CO2 to lower pH will raise Total Alkalinity. High total alkalinity (over 80 ppm) will increase
scale and solids buildup in chlorinator.
WARNING: Use ONLY Pulsar® Plus Briquettes in the Chlorinator. e use of any other treatment chemicals
will void the warranty. DANGER: Under no circumstances mix calcium hypochlorite with other forms of
concentrated chlorine or other chemicals. Fire and/or explosion may result. Caution must be used when refilling
dispenser.
KEEP OUT OF REACH OF CHILDREN
1. Fill the Briquette Tank with Pulsar® Plus Briquettes. e Briquette Tank holds 62 pounds of briquettes.
2. Check the chart below to determine an approximate start-up timer setting for your pool (or be certain that
the ORP Controller is calibrated and the set-points are correct). Set the Upper and Lower Timer Knobs at the
recommended setting.
NOTE: For best chlorinator performance, use the “normal” bottom timer setting. is will assist in maintaining desired
Free Available Chlorine level in pool and help maintain chlorinator maintenance.
3. Open all valves to the pool and to the chlorinator.
4. Monitor the water flow to the chlorinator daily to ensure that a proper flow is being maintained.
5. During the first few days of operation, check chlorine level in the pool frequently to establish the best Timer
setting (or ORP Controller setting) for your pool. Adjust the chlorine output either up or down according to
the table or, adjust the ORP setpoint.

Pulsar®3 Chlorinator Inspection & Maintenance
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. e following is a list of the parts to be
cleaned and the proper procedures to do so.
SECTION A
Cleaning PULSAR® 3 Chlorinator with PULSAR® Plus Acid Cleaner 50
Inspection: 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 filter.
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. 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.
