Placement of Equipment
Select a location for the ozone skid that is as close as possible (preferably within ten feet) to the ozone injection point.
Arrange the skid in a manner suitable for convenient electrical access and allowing for service of the air preparation
system. The M-15/O2 and P-20/O2 enclosures are not rain proof, so it is important to choose a location that will keep the
system away from direct weather and excessive heat.
A suitable concrete equipment pad should be provided. Three mounting holes are located on the bottom skid rails,
allowing the unit to be secured to the floor. Mounting hardware is not provided.
Installation Materials
Use Schedule 80 PVC or suitable ozone-resistant materials for all plumbing connections whenever possible. Also, it is
recommended that unions and valves are used wherever practical. Ozone rapidly deteriorates a variety of compounds;
the following is a list of materials that may be used . . .
. . . with ozone in gaseous phase (at high concentrations):
Viton Teflon
®
Stainless Steel EPDM
Silicon Kynar
®
Hepalon
. . . with ozone in aqueous phase (at low concentrations):
Viton Teflon
®
Stainless Steel EPDM
Silicon Kynar
®
Concrete Hepalon
Schedule 40 PVC Schedule 80 PVC
NOTE: Be sure to use good plumbing practices and install unions and isolation valves wherever the situation
dictates, i.e. pump or injector removal, etc. Secure all plumbing with unistrut or similar hardware.
Tubing Installation
Install the check valve assembly onto the injector if not already completed. Install the 1/4” Teflon
®
tubing from the solenoid
valve (located on the upper right side of the electrical interlock box) to the injector.
All tubing connections between the oxygen generator and the ozone generator and the electrical interlock box have been
completed at the factory.
Check Valve Selection
The ozone check valve is an important component in preventing damage to the ozone generator. All ClearWater Tech M-1500
and P-2000 ozone generators are equipped with a Kynar
®
low pressure check valve on the ozone outlet. A second check
valve should be installed on the venturi injector ozone inlet. This check valve should be matched to the application. A low
pressure Kynar
®
check valve is appropriate for applications where the system pressure will not exceed 40 psi. Higher line
or system pressure installations require a stainless steel check valve.
Note: The cracking pressure (the pressure at which the valve opens) of any stainless steel or Kynar
®
check valves not
sourced through ClearWater Tech must not exceed 0.5 lb. (0.33 lb. is recommended.)
