12. Once the filter is suspended at the proper height,
route the outside tubing to the motor to determine
how much is to be cut off when inserted into the
suction (“In”) side of the motor. Note: the recessed
“IN” and “OUT” ports for the tubes in the motor are
approx 3/4” deep. Note: Do not install the tubing
with tight radius bends, kinks, or without slack.
13. Using a sharp utility knife, cut the tubing square. If
necessary, deburr the tube.
14. Slide the connecting nut over the tubing with the
female threads facing the cut end of the tubing.
Slide the ferrule onto the tube 1/2” to 3/4”, having
the beveled end of the ferrules facing the pump as
shown.
15. Insert the tubing approximately 3/4” into the motor
pump “IN” port (labeled on the motor housing).
Finger tight only.
Do

use Teflon tape. Do
not
use pliers. Do
not
use pipe dope.
Install The Discharge Line
16. In the same manner with the discharge tubing, install the
nut threads and the beveled end of the ferrule facing the
motor. Insert the tube into the motor pump “OUT” port
about 3/4” and finger tighten.
17. Shut off water in the pool or spa circulation system, and
bleed off any system pressure.
18. Locate a suitable point for the acid flow of injection;
make sure that the acid injector is after the spa bypass
system. If there is no 1/2” or 1/4” NPT female fitting at
the location, one will have to be provided.
19. Install the injection fitting or injection check valve. Wrap
the MNPT end of the fitting with 2 to 3 wraps of thread
seal tape.
20. Install the MNPT end of the fitting into the FNPT point
of injection. Hand tighten only. Trim extension tip as
required to put the tip directly in the flow of water.
Filling The Tank With An Acid Solution
21. To create the acid dilution, always introduce water into
the tank first, then add acid to water. Never reversed!
Mix the ratio per manufacturer’s guidelines.
22. Turn on the water system and allow it to reach operating
pressure. Check the entire system for leaks.
23. After a suitable amount of time dosing, verify your
application with test equipment.
