PZ2-1 and PZ2-2 with BYPASS VENTURI
1. Directly after pump and before filter, attach one 1-1/2 inch or 2 inch brass saddle clamp using attached screws.
2. After all existing equipment (including heater, chlorinator, etc), attach second 1-1/2 inch or 2 inch brass saddle clamp to
return line using attached screws.
3. Drill a 1/2 inch hole in the pipe through the hole in the top of each saddle clamp.
4. Apply Teflon tape to threaded end of each 3/4 inch mpt x 3/4 inch hb fitting.
5. Screw 3/4 inch x 3/4 inch fitting snugly into top of each saddle clamp.
6. Cut a 6 inch (15cm) length (plus or minus 1 inch) of 3/4 inch clear hose and connect one end to the 3/4 inch barb fitting on
saddle clamp nearest to pump; secure with a clamp.
7. If the venturi injector is model V3, insert the INPUT end of injector into 6 inch length of hose. If Mazzie injector, make sure
flow is away from saddle; secure with a clamp (an arrow on the side of injector indicates flow direction).
8. Insert opposite end of venturi injector into remaining length of 3/4 inch clear hose and secure with a clamp.
9. Attach loose end of 3/4 inch hose to the 3/4 inch barb fitting on the return line saddle clamp using screw-type clamp.
10. Apply Teflon tape to threads of the two 1/2 inch x 1/4 inch fittings and screw these two fittings into each end of the check
valve.
11. Cut a 6 inch length of 1/4 inch hose and connect one end to the output side of the check valve (flow away from ozone
generator) and other end to ozone fitting on injector; secure with clamps. If V3 injector attach hose to port 1 (port 2 should
be capped.)
12. Mount the PZ2 ozone generator vertically on wall with compressor at lower end, using two holes in rain shield. 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).
13. Attach one end of the remaining length of 1/4 inch hose to the ozone generator and the other end to the inlet side of the
check valve. Making sure flow is away from ozone generator, secure ends with clamps.
14. Slip the M09 Noise Attenuator onto the 1 inch fitting on the rear of the PZ2.
(See item 1 above, Preparing for
Installation.
15. Electrical Installation: System is 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.
Note: If Diatemateous Earth filter, install a 3/4 inch ball valve in the 3/4 inch hose line to the input side of the venturi.
CAUTION: Make sure the voltage is the same as prescribed on the side of the Prozone ozone generator. Overvoltage will void
customer warranty.
PZ2-1 & PZ2-2 with DIRECT INJECTION
NOTE: There must be at least four feet (1.2 m) of return line between the point where the ozone bubbles are injected and the pool.
If there is not four feet of return available, a flexible loop can be added to the return line.
1. Attach a 1-1/2 inch or 2 inch saddle clamp to return line after heater and automatic floor sweep using the attached screws.
2. Drill four (4) 3/16 inch holes in the pipe through the center of the hole in the saddle clamp.
3. Apply Teflon tape to threads of the 3/4 inch x 1/2 inch bushing; screw the bushing snugly into the saddle clamp.
4. Apply Teflon tape to threads of one of the 1/2 inch x 1/4 inch fittings.
5. Screw this 1/2 inch x 1/4 inch fitting into the 3/4 inch x ½ inch bushing.
6. Apply Teflon tape to the threads of the other two 1/2 inch x 1/4 inch fittings.
7. Screw these two 1/2 inch x 1/4 inch fittings into each end of the check valve.
8. Cut a 6 inch (15cm) length (plus or minus 1 inch) of 1/4 inch hose and slide it over the barb on the 1/2 inch x 1/4 inch fitting
screwed into the 3/4 inch x ½ inch pushing. Secure hose with a clamp.
