Optional Features
The following optional features are available on the AFX Series unless
otherwise noted. Certain combinations of options may not be available.
Emergency/

Smoke detector(s). The factory installed smoke detector(s) is designed to
sense smoke concentration in the return air stream. Upon detecting smoke
concentration an audible and visual alarm on the microprocessor will be
activated and the unit will immediately shut-down.
Firestat. A Firestat is available for installation in the air stream. If the return
air temperature reaches 125° F (52° C), the air conditioner will be turned off
and both an audible and visual alarm will be activated on the microprocessor.
Water detector(s). The solid-state water detector(s) activates an audible
and visual alarm on the microprocessor when moisture is detected. The water
detector is provided with 15' (5 m) of wire. Multiple detectors can be used in
the optional secondary drain pan in the sub floor.
Essential/non-essential lockout. When facilities have limited backup
power capacity, this lockout prevents the operation of electrical loads that are
not essential for continued site operation.
External
components
Floorstand. The heavy gauge floorstand raises the unit above the subfloor to
match the height of the raised floor. Heights are available from 6" to 36" (12"
to 36" for downflow units) in 3" increments and are adjustable +/- 1.5".
Adjustment is provided by threaded pedestals. Vibration absorbing pads are
included. The floorstand, pedestal and pads ship loose. Floorstands are
available for seismic applications.
Air deflector. An air deflector ships loose and attaches to the floorstand for
changing air direction from vertical to horizontal.
Plenum. The discharge plenum mounts on top of the upflow unit to direct
and distribute conditioned air. Manually adjustable, double deflecting grilles
are provided on 3 or 4 sides.Plenum shall be painted to match the color of the
unit.
Duct flange. A 1" (25 mm) duct flange is installed on a unit to provide
convenient connection to external ductwork. The duct flange can be installed
at the air outlet on upflow units, or at the air inlet on downflow units.
