NSTALLATION
W Series air handlers are suitable for free-air return as
enclosed in a closet with a louvered door, flush mounted in
a wall, or typical upflow application with bottom return air
duct.
Closet or “ON” the wall applications
Note: If mounted in a closet a louver or grill with at least 1
square foot of face area per ton is required on the door
.
A bracket is supplied for this type of mounting. Attach
bracket to wall so the “open” end faces up, make sure
bracket is level and attached to the studs (2‘’ x 8‘’ blocking
installed between studs at bracket height is recommended).
2‘’ screws are required. Remove the center screw that
attaches the top cap to the back of the air handler. Lift unit
and slide the back edge of the top cap onto bracket.
Flush Mount or “IN” the wall applications
Maintain a 10‘’ clearance from floor for condensate
connections. Mount so air handler is flush with the front face
of studs. Use the 2 holes on each side to attach between
studs. Make sure air handler is level and square before
proceeding. Attach brace in the upright position across the
top of the unit (refer to drawing).

ISTONS
As shipped from the factory, the florator piston installed in
each coil is chosen for the nominal BTUH capacity of the
coil. A label on the liquid line identifies the piston size. For
optimum performance, the piston should be sized to match
the nominal BTUH of the condensing unit. Use the chart
below for proper sizing.
