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

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.
See Section III, on pages 14 - 16 of the manual.
1.1
AC Line Input Voltage Selection (Jumper J1 on Upper PC Board): This control can operate standard 208 - 230 Volt AC - 50/60
208/230 Volt AC line input (Jumper J1 in the "230V" position). To operate the control from a 115 Volt AC line input, set Jumper J1
to the "115V" position. See Figure 2, on page 2.
