The AP is fitted with one circulator, the
performance data to be used to size the sys-
tem, is shown in the graph.
When starting up for the first time, and at
least once a year, it is advisable to check
the pump shaft rotate.
This is necessary because, especially af-
ter lengthy periods of inactivity, deposits
and/or residue may stop it rotating freely.
Do not run the circulator without water.
Where present flo regulator devices
(thermostatic electrical or motorized zone
valves) it is better to inster a by pass on
the collector.
