Maintenance - Pentair CristalFlo II Owner's Manual

Maintenance

You new product incorporates moving parts and withstands high velocity water with
chemicals in it. Some of these parts will wear in the normal course of use and re-
quire regular checks and maintenance. Performing these checks and maintenance
will identify parts that have worn and require repair/replacement before further
serious damage is sustained. A small amount of regular care and attention to your
pool equipment will help ensure long life and trouble free performance.

Maintenance
Check pressure gauge. If pres-
sure increase is greater than
20kPa cleaning may be required.
Check inlet/outlet o-rings for
leaks.
Compare operating pressure of
backwashed filter to initial pres-
sure (when new).
If using Zeolite, regenerate filter
sand. This is important in com-
mercial applications as it aids in
the removal of ammonias.
Perform backwash according to instruc-
tions.
Isolate Pump, turn power off, clean and
grease O-rings or replace if necessary.
If pressure is more than 30 – 40 kPa differ-
ent from new filter, a sand change may be
required.
Add salt to filter sand per supplier. Allow to
sit for 24 hours then backwash, rinse and
return to filter.
