Section 4 Maintenance & Service
c. Check connections.
d. Check that the check valve is installed with the arrow pointing
towards the injector.
e. Be sure that the check valve has not become fouled with debris.
Disconnect the Ozone Tube from the injector. With the pump
running, cover the end of the injector with your thumb, and feel
for suction. If there is sufficient suction without the check valve,
replace the check valve with a new one.
4D-3 Symptom: Ozone Tube becomes yellow/brown and brittle.
1. The high concentration of ozone created by the DEL Ozone family
of ozone generators, as well as environmental conditions like UV
sunlight will tend to deteriorate the supplied Ozone Tube. This
is normal and acceptable, as long as the tubing doesn't become
cracked and leak. Because of this, the Ozone Tube and Check Valve
should be replaced every year.
4D-4 Symptom: Can't get ball to stay in the center of flowmeter.
1. The flowmeter provided is a general tool to setup flow to the
ozone generator. Flow will vary depending on pressures across the
injector, and therefore can be affected by things such as filter or
strainer loading. The ozone generator's efficiency is optimized near
the center of the flow meter. The DEL Ozone generator will still
perform well at flows above and below the recommended range.
However, the ball must be moving and not stuck on the bottom of
the flowmeter.
