Floor Mounted Units
For floor installations, the floor structure must be adequately
designed to support the live weight load of the unit and any
other required support structure. Additional reinforcement should
be provided, if necessary. The floor should include threaded
5/8-inch anchor bolts spaced according to Figure 5.2 and Table
5.1, for securing the unit in place. Anchor bolts should extend at
least 1-1/2" above the surface of the floor to allow clearance for
mounting washers, nuts and bolts (mounting washers, nuts, and
bolts by others).

UNIT LIFTING

Failure to follow proper lifting instructions and applicable
safety procedures could result in property damage, serious
injury, or death. Lifting should only be done by a qualified
rigging company. Use ALL lifting points. Test lift to ensure
proper balance and rigging.
Rigging and lifting of the units should only be done by a
qualified rigging company and follow appropriate industry
standards, including but not limited to the appropriate sections
of ASME B30, OSHA 1910, and OSHA 1926.
1. Follow site preparation instructions for overhead
suspension, floor mounting, equipment stand before
installation.
2. Check the Serial Plate(s) of unit with plans to be sure unit
is properly located. Although units may look outwardly
similar, their function, capacities, options, and accessories
will often vary.
3. Check unit dimensions of both the unit base and the
installation location where the unit will be installed.
4. The provisions for lifting are dependant on how the unit
was shipped:
a. All units with standard blower cabinets (Model Digit
16=A through H) are shipped fully crated with skid
supports below the unit. The unit may be lifted from
the bottom by means of a fork lift or other lifting device
only if the shipping support skids are left in place. DO
NOT attempt to lift the unit from the bottom unless the
shipping skid supports are still in place. When lifting
units, make sure the load is balanced.
b. All units with extended blower cabinets (Model Digit
16=I through L) are shipped without a crate and
cannot be lifted with a fork truck. Use a crane or other
overhead lifting device in conjunction with the lifting
holes for safe unit relocation (refer to the Dimensions
for base rail lifting hole locations). See the following
note #5. If the unit must be lifted from the bottom for
final installation, be sure to properly support the unit
over its entire length to prevent damage.
5. When lifting the equipment with a crane, connect sturdy
steel cables, chains, or straps. For stability in lifting and
lowering and to prevent damage to the unit, include a
spreader bar. Avoid twisting or uneven lifting of the unit.
Test lift the unit to check for proper rigging balance before
hoisting to the desired installation location.

6. Position the unit to its ductwork or where ductwork will be
-
located and suspend or floor mount the unit. For proper
-
operation, the unit must be installed in a level horizontal
-
position. Use a spirit level to ensure that the unit is
- suspended or floor mounted correctly.

7. Refer to the applicable sections to make Venting, Gas
-
Connec tions, Electrical Connections, and Cooling Coil
-
Connections. Make final unit connections to the electric
-
power supply and remote control circuits. Caulk all utility
41.37 line clearance holes on the unit after connections are
41.37 completed.

8. Refer to the applicable sections to make final unit
41.37
connections for venting, gas and electrical utility connec-

tions, control wiring, and cooling system connections if
equipped. Caulk all utility line clearance holes on the unit
after connections are completed.
