PRE-INSTALLATION
1. Check items received against packing list.
2. Do not stack unit components or accessories during storage.
Stacking can cause damage or deformation.
3. If unit is to be stored for more than 2 weeks prior to
installation, observe the following precautions:
a. Choose a dry storage site that is reasonably level and
sturdy to prevent undue stress or permanent damage to
the unit structure or components. Do not store unit on
vibrating surface. Damage to stationary bearings can
occur. Set unit off ground if in heavy rain area.
b. Remove all fasteners and other small parts from jobsite
to minimize theft. Tag and store parts in a safe place until
needed.
c. Cover entire unit with a tarp or plastic coverall. Extend
cover under unit if stored on ground. Secure cover with
adequate tiedowns or store indoors. Be sure all coil con-
nections have protective shipping caps.
d. Monthly — Remove tarp from unit, enter fan section
through access door or through fan inlet, and rotate fan
and motor slowly by hand to redistribute the bearing
grease and to prevent bearing corrosion.
Rigging
Do not remove shipping skids or protective covering until unit is
ready for final placement. Use slings and spreader bars as applica-
ble to lift unit. Do not lift unit by coil connections or headers.
Do not remove protective caps from coil piping connections until
ready to connect piping.
Do not remove protective cover or grease from fan shaft until
ready to install sheave.
Lay rigid temporary protection such as plywood walkways in unit
to prevent damage to insulation or bottom panel during
installation.
Unit Weight Calculation Procedure
Calculate coil water weight for each water coil using the following
formula:
Water Weight = Coil Volume (gal) x 8.345 lb/gal (volume is from
Physical Data table)
Calculate Total Weight:
Total Unit Installed Weight = Unit Dry Weight (see Table 5 ) +
Water Weight (coil 1) + Water Weight (coil 2)
Shipping Bolt and Screw Removal
(39SHK Units)
On 39SHK units ensure that all red shipping bolts and screws are
removed and all other bolts and screws are tight. The red hold-
down shipping bolts are located on both sides of the blower/motor
mounting rails and are accessible through the side access panels.
The red sheet metal screws are located on the discharge duct
collar. All red bolts and screws must be removed for the blower
assembly to be isolated from the cabinet. See Fig. 22.

Unit Suspension
(39SHC/SHF/SHK and 39SM Units)
Acceptable forms of unit suspension are shown in Fig. 23. A field-
supplied platform mount is recommended, especially for larger
unit sizes. Units can also be supported by suspending the unit from
crossbeams at the joint between each unit component. Since the
39SM units lack a baserail, support members should also be
placed along the airway length of the unit in order to prevent buck-
ling. Ensure that suspension rods are secured to adequately sup-
port the unit and that the rods extend entirely through their associ-
ated fasteners.
All 39SH units have 7/8 in. knockouts in each corner of their top
and base panels for suspension rods to pass through, located
3-1/2 in. in from the corners on the center line. It is recommended
that an angle iron or Unistrut
1
framing system be used under the
unit for support (these support pieces should extend approximate-
ly 1 in. beyond each end of the unit width).
Hanging brackets (shipped loose) are recommended for 39SHK
and 39SM unit sizes 07 and above. To install brackets, place in ap-
proximate location and use self-drilling screws to attach to mixing
box. Brackets are sized to allow hanging from the Unistrut fram-
ing system. The Unistrut framing system should be cut to the
length one to two inches shorter than the width of the mixing box
to avoid any interference with the damper linkages.
NOTE: Locate suspension rods so they do not block access panels
or interfere with the electrical, mechanical, or drain functions of
unit.
