VERTICAL UNIT INSTALLATION
Step 1 — Install Wall Mounting Strip and Hang
Base Unit (see Fig. 4)
1. Determine required length of mounting strip. Allow for
length of enclosures and runouts to be used.
Maximum
unsupported length of Carrier enclosures is 2-in. on
either side.
2. Locate strip per job prints. Install straight and level using
field-supplied fasteners through alternate and end holes.
Shim if necessary.
3. Install separate mounting strip above base unit strip for
hanging 36SC or 36ST enclosures if used.
4. Mark enclosure vertical center line on wall near mount-
ing strip.
5. Remove base unit from carton. Retain carton and place
over unit after installation to protect from dirt.
6. Remove unit protective packing
.
7. Do not remove lint screen clips (taped to condensate pan)
or tee and connector (tape to side of slave unit) until
required.
8. Install two No. 10-24 bolts (factory-supplied) through
two No. 10-24 speed nuts provided. (These, or any other
suitable means, will be used for unit leveling.)
9. Mark base unit vertical center line on unit.
10. Determine from job prints or certified prints relative
position of base unit with respect to enclosure.
11. Hang base unit on wall-mounting strip, using center lines
for reference.
12. Level unit by adjusting two No. 10-24 bolts (or other
means selected).
