This document is supplied with Model KBVF-22D (Part No. 9572).

IMPORTANT: The following information and instructions are to be used as a supplement to the KBVF Installation and Operation Manual (Part
No. A40288) until the new manual is available with the addition of Model KBVF-22D (Part No. 9572).  The  KBVF Series has been changed to
a second generation version (2G).  The General Performance Specifications have not changed.  This 2G version has an additional Frequency
Multiplier Jumper, a single Input Line Voltage Selection Jumper, and an additional connector for accessories.  The KBVF manual must be read
and understood before attempting to operate this control.  For further assistance, contact our Sales Department at 954-346-4900 or Toll Free
at 800-221-6570 (outside Florida).

Setting Selectable Jumpers
This control has selectable jumpers which may have to be set  before  the control can  be  used.   See Figure  1,  above,  for  the location  of
jumpers.  WARNING! Disconnect the AC line before changing position of jumpers.
