PUMP
Operating status
Alternative: Intermittent, Continuously, 10 days con-
tinuously
Intermittent: The brine pump starts approx. 20 seconds
before or after the compressor. For a ground water
system, the brine pump starts and stops 2 minutes be-
fore and after the compressor respectively.
Continuous: Continuous operation.
10 days continuous: Continuous operation for 10 days.
The pump then changes to intermittent operation.
TIP
You can use "10 days continuous" at start-up
to obtain continuous circulation during a start-
up time in order to make it easier to bleed the
system.
