General rigging instructions
WARNING
Failure to follow proper lifting instructions 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. Never
lift in high winds.
lifting lug installation
Before attaching lifting equipment, verify location of lifting lugs
or eyes. B- and C-Cabinet sized units have the lifting lugs or
eyes factory installed as follows:
• B-Cabinet sized units without Energy Recovery include
(4) eye bolts at each corner on the top of the unit.
• B-Cabinet sized units with Energy Recovery include (6)
lifting lugs on the base, one at each corner and one on
each length-wise side of the unit between the corners.
• C-Cabinet sized units include (4) eye bolts at each corner
on the top of the unit. For units that include the shipped
separate Energy Recovery Module (model ERM) option,
refer to the latest revision of the Installation and Service
Manual, #MCP15-520, that shipped with the ERM for
separate rigging instructions.
• D-Cabinet sized units must have the lifting lugs installed in
the unit base assembly prior to rigging as follows:
1. Locate the lifting lug kit box, kit # 66802, located in
the supply fan compartment.
2. Install the kit per the "Installation Instructions, Lifting
Lugs D-Cabinet", #MCP15-505, included with the kit.
3. After installing the kit, verify that all (4) lugs are
installed following the instructions in Step 2. Verify
that each lug is secured using (4) Grade 5 bolts
provided with the kit. Each bolt must be torqued to
75 ft-lb.
unit rigging and lifting
Rigging and lifting of the units should only be done by a
qualified rigging company. With the lifting lugs or eyes
identified and installed, the units can be lifted by crane or
helicopter.
1. Follow site preparation instructions for the roof curb or
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 curb
or stand on which the unit will be installed.
4. If the unit will be installed on a roof curb:
a. Thoroughly clean and dry the top of the curb surface.
b. Lay a bead of weather resistant caulking on top
perimeter of roof curb as illustrated in Figure 7.1. Note:
If roof curb is supplied by Modine, full perimeter gasket
material is supplied and caulking is not necessary.
5. When lifting the equipment, connect sturdy steel cables,
chains, or straps with eye loops as illustrated in Figure 6.1.
For stability in lifting and lowering and to prevent damage
to the unit, include a spreader bar as illustrated in Figure
6
6.1. Avoid twisting or uneven lifting of the unit. The cable
length from the lifting point on the unit to the spreader bar
should always be longer than the distance between the
outer lifting points.
6. Test lift the unit to check for proper rigging balance before
hoisting to the desired installation location.
7. Once lifted to the installation location, orient the hoisted
unit to match the ductwork locations and set evenly on the
curb or stand.
8. Following the instructions in this manual, make final unit
connections to the electric power supply and remote
control circuits. Connect the gas lines to the unit heating
compartment. Seal all utility line clearance holes on the unit
after connections are completed so they are watertight.
