INSTALLATION INSTRUCTIONS
APPLICATION
The 40003916 is a replacement powerhead for the
V4043, V4044, V8043, and V8044 fan coil and zone
valves. See Table 1. The powerhead includes the motor,
housing, and 2 mounting screws. Models are available
for low or line voltage applications.
This powerhead is for use with new style valve bodies
(series 6) or old style valve bodies (series 1-5) that have
been converted to accept this powerhead. The new style
valve bodies are identified with a sideways 6 on the
powerhead after the OS number and an indent under the
OS number on the powerhead. See Fig.1. If using an old
style valve, the valve must be converted using Part No.
40003918 (order separately).
Fig. 1. Sideways number after OS number on
powerhead identifies valve series.
