Installer Manual Fleck 2910 - NXT - Installation
Ref. MKT-IM-002 / B - 23.05.2018 49 / 114
If two tanks are in service and both reach Volume remaining = 0, the other two tanks will shift from
standby into service. The lead tank with Volume remaining = 0 will start regeneration. The second tank
with Volume remaining = 0 will enter into standby. If the flow increases past the trip point, a third tank
needs to enter in service. The tank in standby with Volume remaining = 0 will shift into service to
maintain a steady flow. Operating for extended periods in this mode may degrade the water quality.
5.8. Valve connection to piping
The connections should be sealed using PTFE (plumber’s tape) on the threads if using the threaded
connection type.
In case of heat welding (metal type connection), the connections should not be made to the valve when
soldering.
Note
See chapter 3.3. Components description and location, page 17 to identify the connections.
