INSTALLATION
Base Rail Split
A base rail split between the primary coil/fan section and the ac-
cessory sections is optional. If this option has been selected, the
39L unit will arrive at the job site assembled as one piece. The
split allows the unit to be separated at the joint.
If the unit must be separated in the field, follow this procedure:
1. Remove the lifting lugs on the inlet side of the coil/fan sec-
tion and those on the outlet side of the accessory section to
liberate the T-bracket. See Fig 14.
2. Unscrew the flanges (top and sides) around the coil/fan
section and the accessory section. See Fig. 15.
NOTE: If the section-to-section gasket installed at the factory is
damaged while splitting the unit, obtain the required length of
1/8 in. x 1-1/4 in. foam gasketing locally.
After rejoining the split sections, fully tighten all AB 1/4 in. 3/4 in.
screws on the flanges and the AB 1/4 in 5/8 in. screws on the
flanges. See Fig. 16.
