It is recommended to provide sinus filters on the VFD to prevent bearing damage on fan motors.
CAUTION
Refer to fan motor nameplate data when programming a VFD.
The purpose of a low level cut out switch for pump protection is to protect the pump from running dry in case of
make-up failure or extreme water loss. The status of the alarm can be checked prior to pump start-up, but should
not be considered during the first minute after start-up, since activation of the pump can cause a water level drop,
that might trigger the alarm. Normal make-up will stabilize the water level after a short period of time.
