INSTALLATION PREPERATION AND OVERVIEW
IF LINE OR PUMP PRESSURE EXCEEDS 70PSI, A PRESSURE REGULATOR WILL BE REQUIRED FOR
THIS SYSTEM
(By-Pass and Pressure Regulator are not supplied)
1. Pre-measure area required for all components as per sizing.
2. Shut off main water supply and drain water line.
3. Cut water line after water meter or pressure tank.
4. Place Aclarus system in pre-determined area.
5. Place filter(s) in pre-determined area. (Usually beside Aclarus system)
6. Install by-pass valves for future use or service.
7. If required install pressure regulator (not supplied).
8. Assemble system as required using unions and equipment supplied –NOTE
System is only built to connect components solely at specific locations
9. Plumb Aclarus system and other components into water supply.
(These components may vary depending on your application)
10. Install Gas-off chamber as per Drawing #3. (Be sure to apply Teflon to
threads if not already applied)
11. Using ¼” PVC braided hose, vent gas-off chamber to exterior of dwelling OR
down a drain –if putting to the outside air be sure to not allow it to freeze.
12. Connect air dryer braided hose with silica gel (provided). IMPORTANT:
Make sure to connect the top (cap) end of the air dryer to the braided
hose and leave the bottom fitting open to the air.
13. Ensure the power switch on front of Aclarus head is in the OFF position.
Check Serial Number plate for unit voltage and connect to appropriate
power source.

15
14. Install filters after the ozone system (NOTE: Ensure activated carbon filter
or media is the last filter before discharge.
15. Ensure that the outgoing valve of the unit is closed
16. Wait for the Aclarus system and tank to fill entirely with pressure stabilized.
17. If filter(s) are equipped with by-pass valves, make sure they are in the by-
pass position.
18. Open by-pass valves on Aclarus system slowly.
19. If a pressure regulator was installed on system, using the LED display on the
electronic pressure switch set incoming pressure to NOT OVER 70PSI.
20. Turn power switch on front of Aclarus head to the on position.
21. With all taps closed the Aclarus system should pressure up and shut off.
22. Quickly open and close the outgoing valve on the Aclarus system to start
the “priming” process to get ozone into the system before use. Repeat 5-8
times for a total of at least 5-10 minutes of re-circulation
23. To backwash filter(s) connect to appropriate power source.
24. Remove all aerators from fixtures (taps). Do not use Toilets during this
process. (Small particulates of media could plug fixtures and require them
to be cleaned)
25. On the filter immediately after the Aclarus system slowly open incoming
valve on by-pass assembly leaving outgoing valve closed and allowing filter
to fill with water and pressure to stabilize. (Filters not equipped with by-
pass valve will already be full of water.) (Backwash only one filter at a
time)
26. Set backwash cycle time for automatic backwashing filters
27. After the filter has run through its cycle, open outgoing valve on by-pass
assembly.
28. If Aclarus system is equipped with another filter repeat steps above.

16
29. If Aclarus system was equipped with only one filter or if both filters have
run through their cycle, open the tap closest to the Aclarus system to flush
out any small particulates of media that might have come through. Run for
a few minutes. Repeat with other taps in house.
30. Replace aerators in fixtures (taps).
31. Aclarus system should start a few seconds after water use and stop about
10-40 seconds after water use has stopped (depending on settings).
DO NOT OVER TIGHTEN FITTINGS!!

Chapter Two: System Installation and Start Up
Detailed installation instructions for installation are provided in this manual. Please also
refer to the Site Specific Installation Sheet if provided with the Aclarus System for any
additional information about any custom modifications specific to your model.
Installing the Aclarus System requires these steps to prepare the site:
Plumbing the water source into the system.
Venting the off-gasses safely.
A 15 Amp 110V power outlet within four feet of the system.
NOTES:
Once installation is complete, the system must be filled, the filters
backwashed, and samples taken to ensure water quality.
If line or pump pressure can exceed 65 psi (4.5 bar), a pressure regulator is
required. The pressure regulator and bypass are not supplied.
Installation Example
Example One
Pre-filter or sand filter is occasionally
required (not shown) with high sediment,
sand or turbid water.
This post filter shown is an activated
Carbon replacement filter and must be
placed as the final filter.
For very high iron, algae or other issues
a sediment filter prior to the activated
carbon may be required. Contact
Aclarus for more information.
Example Install #1: Typical installation example. Post filter installed (blue casing far right) is mandatory
activated carbon filter and included with the system package.

NOTES:
Always use ozone resistant plumbing such as Schedule 40 or 80 PVC pipe and
fittings, PVC Braided Hose and fittings, or PEX hose with Kynar fittings
between the ozone system discharge and the activated carbon filter.
Copper brass or other oxidizable plumbing parts components should only be
used after an activated carbon filter.
Always check plumbing connections to ensure there is nothing loose to cause
a leak
Always ensure that the Gas-off is installed properly and securely.
Always install an activated carbon filter downstream from the ozone system.
In some cases two post filters are required
Some Systems DO NOT have a water column and instead use a backflow
preventer “check valve” in line.
Installation
Materials
In addition to the system supplied by Aclarus, the following materials are, or may be,
required for installation:
Pressure regulator (if required)
Teflon tape
Associated pipe, fittings, primer and glue for connecting of system to existing
plumbing
Installation tools such as pipe cutter, channel locks, etc
NOTE:
Use only ozone compatible plumbing components from the discharge of the
Aclarus Ozone Water System to the Activated Carbon filter.
Schedule 40 or 80 PVC (pipe or braided hose) and/or PEX with ozone
compatible fittings such as poly inserts.
Avoid copper, brass, or other oxidizable plumbing parts. They will break down
over time and can result in leakage and or affect overall system performance.
Always install an Activated Carbon filter between the Aclarus ozone system
and existing plumbing.
