FAN POWERED TERMINAL UNIT OPTION
MODEL SERIES: 33SZ, 35S(ST), 37S(ST), 38F AND 38S
NOTES:
1. The FN3 line voltage enclosure is an ETL listed option.
The FN3 was developed for Nailor fan powered terminal
units in order to help meet NEC clearance requirements.
Standard enclosures are mounted on the side of the
unit and effectively add 42" (1067) to the terminals
width footprint. Very often there is insufficient clearance
in the ceiling plenum due to physical obstructions to
accommodate this. The FN3 provides flexibility in that it
may be field positioned in any orientation that provides the
NEC clearance requirement.
2. The FN3 Line voltage enclosure ships loose with a 48"
(1219) flexible conduit connection to the terminal unit. The
enclosure should be field mounted either on or remote
from the terminal unit in a position that meets (NEC)
clearance requirements.
The controls enclosure is supplied with mounting angles,
which ship loose for field attachment.
