Step 3 — Provide unit support.
Refer to Fig. I — Dimensions, and Table 1 —
Physical Data for unit size and weight.
Construct a stand or frame of I-beams or angle
iron that supports unit adequately, if desired. The
floor and floor joists of existing buildings may
require reinforcement; follow applicable codes.
Step 4 — Rig and place unit.
Provide space around unit for service, filter access
and overhead clearance as indicated in Fig. 1.
Move and store unit in upright position.
50BA,BB004 AND 006 — Use rollers under ship­
ping rails. Unit may be moved by hand truck on any
side. Do not remove shipping rails until unit is in
final position.
50BA008 THRU 064 — Use slings with spacer under
base skid to prevent panel damage when using hoist.
Raise base skid on blocks and remove bolts. On 028
thru 064 units, unbolt fan section from skid.
Units as shipped are adequately dampened
against vibration. If additional dampening is de­
sired, place sponge rubber, rubber mat or fiberglass
roof insulation between floor and base of unit or
install vibration isolators.
