INFORMATION
NOTE: Be certain to count the number
of complete thread rotations Observe
the number of turns reference Table 6 to
determine how tight to make the quick
connect couplings

Continue to hand thread until slight resistance is
observed

Once slight resistance is evident, continue to tighten
the fittings using appropriate size wrenches listed in

If the quick connect still feels loose, tighten just a bit
more until complete resistance is evident
INFORMATION
NOTE: Once tight, refrigerant should be
able to pass through the quick connect
couplings If problems with low refrigerant
pressure appear during system startup,
double check the tightness of these quick
connect couplings as loose fittings will
restrain full refrigerant flow.

Move the Blower Section into position of installation
making sure the side that the blower can be seen will
mate up with the large opening in the Cooling Coil
Section
14�
Lift the blower section up onto the Compressor Section
15�
Use the remaining mounting hardware to connect the
Blower Section to the Cooling Coil Section
16�
Using the appropriate size wrenches, hand-tighten all
mounting hardware
INFORMATION
Note: seismic isolators are shipped
completely locked into position Once
the blower section is installed the spring
isolators adjusted to loosen the blower on
isolators The blower should be allowed to
float on the isolators approximately ½" to
1" side to side and back and fourth.
17�
Once the supply air blower is installed, the spring
isolators under the supply air blower must be
loosened It is the responsibility of the installing
contractor to loosen the spring isolators These
isolators are tightened for shipping purposes only
They must be loosened for proper operation
