PUMP ADJUSTMENT
Brine side
F1355 has brine pumps that operate at a fixed speed.
To ensure the correct flow in the brine system, the brine
pumps must be adjusted.
The pump speed is adjusted with both compressors in
operation and EP14 at nominal speed. Wait until the
system is in balance (ideally 10-15 minutes after com-
pressor start).
Set the speed of the brine pumps in menu 5.1.9. Read
off the speed that the brine pumps should have from
the diagrams below.

To set the correct flow in the heating medium system,
the heating medium pump must run at the correct
speed. F1355 has a heating medium pump that can be
automatically controlled in standard mode. Certain
functions and accessories may require it to run manually
and the correct speed must then be set.
