4.3 Installation of tapping saddles for probes ("free-standing" version) and product
injections
Recommended for installation as a "free-standing" version:
In order for the values measured by the probes to be as representative as possible of the water in the
pool, the probes should be positioned between the pump discharge and the inlet to the filter's multi-
way valve. In any case, they should be located before any heater and before the injection of chemicals.
The injection of chemicals should be done after all devices, just before the water is returned to the
pool.
It is possible to mount the tapping saddles on a bypass circuit in order to isolate them hydraulically for easier
and faster removal of the probes ("no water pressure") and to leave the filtration running (especially during
active wintering).
