in right- or left-hand applications. The coil may tip into
the drain pan once it is clear of the cabinet. Support the
coil when removing it.

seal as illustrated in Figure 4.
6.
Rotate horizontal drip shield 180º front-to-back.

8.
Rotate top cap 180º front-to-back and align with
unused screw holes. Holes must align with front and
back coil end plates. The top cap has a 45º bend on
one side and a 90º bend on the other. The 90º bend
must be on the same side as the horizontal drain pan
as illustrated in Figure 4.
NOTE: Be very careful when reinstalling the screws
into the coil end plate engaging holes. Misaligned
screws may damage the coil.
9.
From the upflow position, flip cabinet 90º to the left
and set into place. Replace blower assembly. Secure
coil in place by bending down the tab on the cabinet
support rail as illustrated in Figure 4 and Figure 5.
10. Install the horizontal shield (-060 model only) on the
front edge of the horizontal drain pan as illustrated in
Figure 5.
NOTE: For horizontal applications in high humidity
areas, remove the downflow rail closest to the drain
pan. To remove rail, remove screw from rail at back
of unit and at cabinet support rail. Remove downflow
rail then replace screws. Also, seal around the exiting
drain pipe, liquid and suction lines to prevent infiltration
of humid air.
