2 Introducon
The Pulsar® Acid Plus feeder creates a consistent soluon of sodium bisulfate acid used for pH reducon.
2.1 OverviewofOperaon
The feeder operates as follows:
1. Pulsar® pH Down (+4) is loaded into the hopper suspended over the soluon reservoir.
2. The external solenoid valve power supply is plugged into a chemical controller pH dosing output.
3. When the chemical controller calls for a pH correcon, the feed solenoid valve opens allowing Water from the pool return to enter the
inlet water manifold at the proper supply ow rate.
4. Water sprays the boom of the basket through three 90° full cone nozzles.
5. Pulsar® pH Down (+4) dry acid dissolves and creates a 93% sodium bisulfate soluon. 10 lbs of sodium bisulfate is equivalent to 1 gallon of
muriac acid..
6. The sodium bisulfate soluon lls the reservoir liing the oat connected to the discharge valve unl the valve opens.
7. With the discharge valve and outlet tubing connected to a venturi, the vacuum generated by the venturi sucon drains the reservoir tank
of the acid soluon, sending the soluon back into the pool return.
Note: If using the same booster pump and Venturi as the precision feeder as shown in
the schemac, set booster pump to Always On by seng dip switch 4 to OFF in the
control box.
Note: If not using a Pulsar® Precision feeder as the primary sanizer, a dedicated booster
pump and venturi is required for operaon of the Pulsar® Acid Plus feeder.
Note: If not using the Pulsar® Precision feeder control box for booster pump operaon,
other means of interlocking the booster pump to the pool pump is required to
protect the booster pump and prevent accidental dosing in a no ow condion.

must be performed by a licensed electrician in accordance with the Naonal
Electric Code (NEC), Occupaonal Safety and Health Act (OSHA) in the United
States, and all local electrical codes. Failure to properly install and wire this product
can result in property damage, injury, or death, and may aect warranty coverage.
2. Site meets criteria noted in 4.1.1 Site Requirements.
4.1.1 Site Requirements
The feeder must t in the selected room with enough clearance for maneuvering and servicing the equipment.
Recommended clearance for feeder installaon is 48" L x 48" W x 76" H [121.9 cm x 121.9 cm x 152.4 cm]
Minimum clearance for feeder installaon is 29 L x26.5" W x45.9" H [73.6 cm x 67.3 cm x 116.6 cm].
The room must have proper venlaon.
The room must be climate-controlled between 40°F – 90°F [4°C – 32°C].
Required electrical service is as follows:
100 - 240V AC / 15 – 20 Amps dedicated outlet
60 Hz Single phase only (for installing the 1HP booster pump without a Pulsar® Precision feeder)
50 Hz systems require locally sourced booster pump (see booster pump secon for more info)
Determine the inlet and outlet locaon of the booster pump and venturi loop.
It is preferable to install this loop across the heater bypass valve to maximize the pressure dierenal of the system to enhance
performance.
The booster pump sucon should always be downstream of the pool lter(s) to ensure the use of clean ltered water to protect the
solenoid valves. Refer to the process ow diagram in secon 2.2 for proper locaon of piping connecons
The booster pump and venturi should be located to minimize the use of 90° elbows on the venturi outlet

5.4 Feeder Setup if pairing with a Pulsar® Precision Chlorine Feeder
Refer to the Pulsar® Precision operaon and installaon manual for chlorine feeder installaon instrucons
Note: When using the same booster pump and venturi as the Precision feeder as shown
in the schemac in gure 1, the booster pump should be wired through the Pulsar®
Precision control box to benet from the safety features of the ow switch. Refer
to secon 5.6 and 5.7 of the Precision manual for instrucons.
Note: When using the same booster pump and venturi as the Precision feeder, set the
booster pump to Always On by seng dip switch 4 to OFF in the control box. This
will allow the booster pump to provide constant ow to both feeders, except for
when there is a No Flow condion in the pool recirculaon piping.
Note: With an average of 30 gpm through the 1 ½” pipe and 3 gpm at the sucon, the
move ow through the venturi provides roughly a 10 to 1 diluon rao of water to
chemical soluon injected at the venturi sucon. Addional diluon occurs when
the soluon is introduced at the main pool piping.
Note: For any custom installaon inquiries, such as using two venturis or a dierent
booster pump, contact your sales rep for support.
1. Refer to the schemac in Figure 1 and booster pump and venturi assembly (Figure 3 and Figure 4) for guidance
2. If installing the Pulsar® Acid Plus dry acid feeder with a Pulsar® Precision chlorine feeder, add the oponal ½” threaded Tees on the booster
pump discharge and venturi sucon as shown in Figure 3 and Figure 4.
3. The Tees will allow the use of both feeders on one booster pump and venturi bypass.

5.5 Wire the Booster Pump to facility power (Generic Chlorine Feeder Use)
Using a cered electrician, connect the booster pump to facility power using
12 AWG or bigger wire.
Warning: Risk of dangerous or fatal electric shock. Be sure that power to the
motor circuit is o before working on wiring, wiring connecons,
or the motor. Re-install the motor end cover and all other wiring
covers before turning on the power.
Note: Be sure no other lights or equipment are on the same circuit as the
booster pump.
Note: Use Ground Fault Circuit Interrupter (GFCI) as a master on-o
switch.
Note: If installing WITH a Pulsar® Precision chlorine feeder, wire the
booster pump directly to the feeder control box to benet from
safety and energy saving features.
1. Remove the booster pump motor end cover to expose the pump’s dual-
voltage selector, Figure 5.
2. If you have 230 V motor supply voltage, conrm that the plug is set for 230 V. The arrow on the plug will point to the 230 V posion, which
is the default posion of the pump (the plug only connects with one prong in this posion).
3. If you have 115 V supply, pull the plug straight up and place it on the two brass prongs so that the arrow points to the 115 V posion.
4. Replace the booster pump end cover to complete the booster pump wiring.
5.6 Prime the System
Allow pool water to enter the 1 ½” and ½” piping and tubing to conrm overall water ghtness
1. Open the 1 ½” inlet ball valve at the booster pump sucon and allow water to enter checking for leaks
2. Slowly crack open the booster pump discharge union allowing water to ow out conrming that the booster pump is fully primed.
3. Reconnect and ghten the discharge union.
4. Open the 1 ½” outlet ball valve fully priming the enre booster pump / venturi loop.
5. Open the ½” gray inlet and outlet feeder ball valves allowing water to reach the feeder(s).

4. With the solenoid valve plugged into the chemical controller pH control output, test the solenoid and feeder operaon
Note: Refer to the chemical controller user manual to manually call for pH down
5. Check that the solenoid valve energizes. There should be an audible click that occurs when the valve receives power and opens.
6. With the solenoid valve energized, open the hopper lid, ensure that water is coming out of the three blue spray nozzles, and the nozzles
are facing up
7. With water connuing to come out of the spray nozzles, ensure that the DV and feeder discharge is operang correctly, and water is pulled
out of the base by the venturi. This can be visually conrmed if using the clear ½” discharge tubing
8. If the feeder, booster pump, and venturi appear to be operang correctly, stop the chemical controller pH control output,
9. Shut the ½” feeder inlet and outlet ball valves coming from the booster pump and venturi to isolate the feeder and prepare the feeder for
operaon
6.2.2 FeederPreparaon
1. Open hopper lid.
2. Place meshed grid into the hopper.
3. Put on the appropriate PPE: long sleeved clothing, rubber gloves, apron, dust mask, and safety glasses.
Danger: Use suitable personal protecve equipment (PPE) at all mes to avoid physical
contact with sodium bisulfate. Failure to do so may result in death or serious injury.
See the Safety Data Sheet for addional informaon and precauons regarding the
proper handling of Pulsar® pH Down (+4).
Danger: Fire or explosion could result from contaminaon or use of any other chemical
compound! When lling the hopper with sodium bisulfate acid, use a scoop
dedicated for this purpose.
4. Use a dedicated scooper to add Pulsar® pH Down (+4) into the hopper on top of the meshed grid.
5. Plug the solenoid valve power supply into the pH control output of the chemical controller
6. Close hopper lid.

7 OperaonInstrucons
Warning: The use of Pulsar® pH Down (+4) dry sodium bisulfate reduces the pH in a pool.
Ensure the chemical controller’s pH control output is congured for pH down
control. The use of this feeder and chemical with a pH up control conguraon will
result in over dosing acid and lowering the pH to unsafe levels.
Cauon: Use of any other chemicals other than the Pulsar® pH Down (+4) for use with this
feeder shall void this warranty.
Note: When using the same booster pump and venturi as the Precision feeder, set the
booster pump to Always On by seng dip switch 4 to OFF in the control box. This
will allow the booster pump to provide constant ow to both feeders, except for
when there is a No Flow condion in the pool recirculaon piping.
To operate the Pulsar® Acid Plus Feeder:
1. Open the ½” feeder inlet and outlet ball valves coming from the booster pump and venturi
2. Ensure the feed solenoid valve is plugged into the chemical controller pH control output for pH down
3. Ensure there is Pulsar® pH Down (+4) in the hopper on the meshed grid
4. Ensure the booster pump Is powered on
a. Ensure the booster pump is powered on at the facility breaker if using with a chlorine feeder OTHER than a Pulsar® Precision.
b. Ensure the Pulsar® Precision control box is powered on and in ORP mode if the booster pump is wired directly into the control box.
5. Set the desired pH setpoint on the chemical controller and follow the chemical controller user manual for addional instrucons on pH
control automaon.
6. When a pH reducon signal is sent by the chemical controller, the feed solenoid valve will energize and open, and a feed cycle will start
creang acid soluon for injecon into the pool
7. Once pH reducon demand terminates, the solenoid valve will de-energize and shut, and the feeder will stop creang acid soluon unl
the next pH reducon demand is sent.
8. Refer to 6.2.2 Feeder Preparaon to rell hopper with chemical as necessary
