13. Quick install tips
1. To insure proper air venting of your system,
place Alpha in Fixed Speed III mode until all
air has been removed. Isolating zones during
this process will ensure proper air removal.
2. For balancing manifold zone(s) applications,
utilizing Constant Pressure mode 1 or 2 and
only one zone at a time during balancing will
ensure proper flow rate to each zone.
3. Always review your boiler minimum flow
rate requirements if utilizing Alpha as a
primary pump. Select one of the fixed speed
modes for boiler primary pump applications.
4. In general, for maximum energy savings and
comfort level, start with the AutoADAPT™
mode.
5. You may change hydraulic selection while
pumping. No permanent damage will occur. In
fact, Grundfos encourages testing the various
hydraulic modes with your hydronic system to
ensure maximum energy savings and comfort
level.
6. Zone panel control applications — when there
is a call for heat and power has been sent to
the Alpha pump, the Alpha will remember and
restart from the last duty point and hydraulic
mode.
