INSTALLATION
A base rail split between the primary
Base Rail Split —
coil/fan section and the accessory sections is optional. If this
option has ben selected, the 39L unit will arrive at the job site
assembled as one piece. The split allows the unit to be sepa-
rated 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
section and those on the outlet side of the accessory sec-
tion 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.
CAUTION
Ensure that a good seal is created between both sections
before continuing. A poor seal may result in equipment
damage.
NOTE: If the section-to-section gasket installed at the factory
is damaged while splitting the unit, obtain the required length
of
