12.4 Bearing run in mode
Bearing run in mode (BRIM) is a start-up sequence for the pump designed to
precondion the bearing to opmise bearing life. The pump goes through a number of
speed steps before reaching full speed.
The BRIM process last around 4.3 hours and the LED indicates when this is running.
BRIM mode can be cancelled by sending a stop signal and then start signal to a pump
currently running the BRIM process. This is NOT recommended and may invalidate
the warranty.
BRIM mode is either triggered:
▪ automacally by the pump
▪ manually thr
ough nST2
▪ manually through the TIC, or
▪ by pressing both speed adjustment push buons (located behind the service
cover) simultaneously for 2s on the pump.
