In consideration of above all reviewing points, SCT hereby suggests you to install the
permanent inverter on the existing motor with logic for auto operation. In this case, for these
pumps (P-6001A/B), as SCT strongly believes that the inverters are suitable for existing motor,
SCT shall guarantee the motor for 2 years after replacement. However, in case of having trouble
on the motors during 2 years of warranty period, SCT shall change the existing motor from
general type to inverter type. And, the motor will be guaranteed again for 1 more year from
replacement.
This suggestion is made and referred by/to following considerations;
The slow speed start-up for the sensitive magnetic driven pumps, which transfer the vapor
mixed liquid, can run smoothly during initial start-up. After stable condition from the initial startup
of reflux pump, this pump will be operated for the required flow and delivery pressure with
the fixed speed
