1. SELECT BLOWER
Correctly sizing the blower for your application is a critical step to the sustained operational quality
of your Jandy Pro Series Pool and Spa Blower. Damage or failure due to an improperly sized
blower is not covered under warranty.
SIZING WORKSHEETS:
The worksheets below will guide you through the proper sizing
calculations for your application.
