Henden pH Dosing Pump Owners Manual
6.2 Maintenance of the Peristaltic Tube
and Roller Holder
The Henden pH Dosing Pump uses a roller holder and
a “squeeze” tube to pump the acid into the pool. This
tube is perishable and must be replaced periodically. We
recommend replacement approximately once per year.
The tube should be visually inspected regularly for leaks
or damage. It is recommended that the roller holder be
periodically inspected and replaced every 2 years.
6.3 Maintenance of the Probe
Over time, in addition to the normal wear of the probe,
according to use and water quality that is more or less
calcareous, measurement will deteriorate. A thin layer of
limestone with other elements present in the pool water
will deposit on the sensing element of the probe. For
assistance in overcoming this issue, please contact:
1300 HENDEN (1300 436 336).
6.4 Controller Wintering
Only in areas where subzero temperatures are experienced
•
During winterising, you must protect the peristaltic tube.
•
It is advisable to remove the peristaltic tube and flush
it with fresh water. Once complete ensure the tube is
completely dry and re-install.
6.5 Probe Wintering
•
During winterising, the probe must be removed from of the
installation and pipe work.
•
The protection cap as shown on page 8, must be filled with
fresh water a 1/3 of the way up.
•
Place the probe into the protection cap and water and store
in a safe place until after the winter period is over. (Re-
install as shown on page 8.
