(If using a DE filter)
1. Turn pump OFF.
2. Locate section of plumbing in which you choose to install the ENTRANCE leg of the bypass. Location should be in any
accessible area after the pump, but before the filter.
3. Install a PVC Tee that has ¾ FPT, with the threaded portion of the Tee facing upward, or an alternate method is to drill and tap
your existing plumbing for a ¾ FPT.
4. Locate section of plumbing in which you choose to install the EXIT leg of the bypass. Location should be in any accessible
area after the filter, and heater (if equipped).
5. Install a PVC Tee that has ¾ FPT, with the threaded portion of the Tee facing upward, or an alternate method is to drill and tap
your existing plumbing for a ¾ FPT.
6. Apply Teflon tape to the threads of the (2) ¾” MPT x ¾” HB fittings, part number 20678, and screw the fittings into the (2) PVC
Tees you just installed, (or the pipe you drilled and tapped in steps 3 and 5).
7. Cut a 6” length of ¾” hose and connect one end to the fitting on the entrance side of the bypass, (after the pump, before the
filter), and secure with a metal clamp.
8. Connect the other end of the 6” hose to the INLET side of the Venturi Injector and secure with a metal clamp.
9. Attach one end of the remaining ¾” hose to the OUTLET side of the Venturi Injector and secure with a metal clamp.
10. Attach other end of ¾” hose to the fitting on the exit side of the bypass, (after the filter/heater), and secure with a metal clamp.
11. Mount the PZ2 Ozone Generator(s) vertically on a wall with the compressor unit next to the Ozone Generator(s). Place system
at or above water level. If unit must be mounted below water level, loop the hose so that at some point it is above water level
(a solenoid control valve may be necessary).
12. Apply Teflon tape to the threads of the ½” MPT x
⅜
” HB fitting, part number 20231, and screw it into the end of the Check
Valve that has the spring in it, (This is the INLET side of the Check Valve). Mark this end as “INLET”.
13. Apply Teflon tape to the threads of the ½” MPT x ¼” HB fitting, part number 20230, and screw it into the opposite end of the
Check Valve. (This is the OUTLET side of the Check Valve). Mark the end as “OUTLET”.
14. Cut a 6 inch length of ¼” hose and connect one end to the OUTLET side of the Check Valve (with the ¼” hose barb fitting) and
the other end to the open ozone port on the Venturi Injector (Marked #1). Secure with plastic clamps.
15. Cut a length of
⅜
” braided hose long enough to reach between the Ozone Generator(s) and Check Valve.
16. Attach one end of the
⅜” braided
hose to the Ozone Generator(s) and the other end to the INLET side of the Check Valve
and secure ends with plastic clamps.
17. Cut a length of
⅜
” braided hose long enough to reach between the Ozone Generator(s) and compressor unit.
18. Attach this length of hose from the compressor unit to the Ozone Generator(s) and secure with plastic clamps.
19. Electrical Installation: System is either 120 or 240 VAC, 50/60 HZ. Wire Prozone ozone generator system to circulation pump switch
or timer. Prozone system and circulation pump should be started simultaneously. Use N.E.C. or local code grounding and
installation procedures for swimming pool equipment.
CAUTION: Make sure the voltage is the same as prescribed on the side of the Prozone ozone generator. Overvoltage will void
customer warranty.
