Installation; Peristaltic Pump; Measuring Chamber - Hayward AquaRite + Owner's Manual

Peristaltic Pump

The Peristaltic Pump is used to inject diluted liquid hydrochloric acid. The unit should be located within 3.5 metres of the location on
the return to pool piping. Although the pump is designed for outdoor use, it is advised to mount the device in the shade to shield it from
continuous direct heat while ensuring adequate free flowing ventilation. Fasten the pump to a rigid structure with screws or similar.
The device must be installed last on the water return line, after any equipment (heater, cell, etc.). Use the blue 6 mm tubing for suction
(connecting the acid tank and the peristaltic pump) and the blue 6 mm tube for injection via the Chemical Injection Tee (connecting the
peristaltic pump and the injection valve). Ensure the Faucet Tee is glued in appropriately to the existing plumbing.
(See page 3 for the Installation Schematic)
Conneting the Chemical Suction and Cemical Return Lines:
It is recommended where a chemical drum leak could create a safety hazard or damage flooring, that the drum is located within a
containment vessel or bund made from a suitable material to contain the chemical.
1. Remove the lid from the drum or container and take a 6.0 mm drill bit and drill a hole through the middle of the lid.
2. Pass the blue 6 mm tubing through the hole in the lid and extend by approximately 30 cm and then slide the white tube weight over
the tube so that the tube exits it from the chamfered end.
3. Soak the tube weight end of the tube in hot water to soften and then push it over the nipple on the suction filter. Slide/screw the tube
weight down over the tube and suction strainer nipple until the weight is sitting on top of the suction strainer.
4. Slide tube through lid so that when it is fastened to the drum or container the suction filter just sits on the bottom of the drum or
container.
5. Run the blue 6 mm Chemical Suction Line tube to the inlet of the pump (left hand side) and trim to length.
6. Remove the compression fitting nut on the squeeze tube and slide it over the blue tube.
7. Soak the blue tube in hot water to soften and then push it over the short male nipple on the squeeze tube and firmly hand tighten the
nut.
8. Repeat steps 6-7 for the Chemical Return Line, connecting the blue tubing to the outlet of the pump (right hand side). Then run the
tubing to the Chemical Injection Tee, trim to length and insert into the push fit fitting and tighten.
The ACID feed system and any Liquid Chlorine feed system should NOT be stored in the same room as other chemicals or chemical tanks.
The diluted Hydrochloric Acid (HCL) is stored in the appropriately sized drum or closed container near the pump. The Hydrochloric Acid
is sucked from the drum or closed container via the 6 mm blue suction tube, through the squeeze tube of the pump, and then pumped
through the 6 mm blue tube and check valve into the Return to Pool Line.
WARNING – Pool and spa components have a finite life. All components should be inspected weekly and the Squeeze Tube, Non-Return Valve,
along with the suction and discharge hoses should be replaced at least every 6 months or sooner if component degradation is evident.
Nb These components are wear items and are only covered by warranty for manufacture defects.
This system is designed for the following:
» Hydrochloric Acid (HCL) diluted to 16.5% for pools or 11% for Spas or Pool/Spa combinations.
Hayward recommend the following when the system is used with Hydrochloric Acid:
» For pools, Hydrochloric Acid diluted to 16.5% must be used. This is commercially available already diluted or can be achieved by diluting
commercially available 33% HCL at a rate of 1 part HCL to 1 part water.
» For Spas or Pool/Spa combinations, the dilution rate of 33% HCL will need to be changed to 1:2 or 1 part of HCL to 2 parts water to
become HCL diluted to 11%.
» Using diluted Hydrochloric Acid, the container MUST be limited to a volume of 5 litres for spas or per 12,500 litres of pool volume. So
a 25,000 Ltr pool would have a 10 Ltr container of 16.5% diluted HCL.

Measuring Chamber

Assemble the measuring chamber by applying thread tape to the threads of the valves and plugs and then fitting them to the chamber as
shown in the diagram on page five(5). Only tighten the valves and plugs by hand - DO NOT USE TOOLS TO TIGHTEN - YOU WILL CRACK
THE MEASURING CHAMBER. If they leak, remove them and apply extra thread tape. Fasten the measuring chamber to a rigid structure
with screws or similar so that when the pH probe is installed the cable will reach the pH BNC connection on the unit. DO NOT CUT THE
PROBE CABLE. If its too long, coil it up. If its too short, move the Measuring Chamber closer to the unit. The inlet line connects to the
Influent Tee after the filter and before the temperature probe. The outlet line then connects to th Effluent Tee before the pump intake.
Ensure the faucet tees are glued in appropriately to the existing plumbing.
(See page 3 for the Installation Schematic and page 5 for detailed instructions.)
All the metal components of the swimming pool should be equipotentially bonded as per AS/NZS 3000 Wiring Rules' Latest Edition if required.
