INCOMING WATER
Incoming water pressure must be between 14 PSI and 80 PSI. If your water pressure is above 80 PSI you will
need a pressure regulator for your sterilizer. Test your water pressure occasionally to make sure the system is
performing. Extremely hot or cold incoming water will damage the system and cannot be used. Do not install
where water hammer conditions exist, you should install a water hammer arrestor
LEAKS
