8.0 Installation Procedure for Modular Outdoor Units
Lifting Lugs:
Install the lifting lugs on the longer side of the module or unit (if not already done) PRIOR
TO RIGGING, as indicated on the lifting lugs drawings.
STEP 1: Installation of the Neoprene gasket (figure 6)
Before installing the unit, it is important that a 3”x5”x1/8” foam gasket be installed at every
module joint at the floor wall junction (refer to figure 6). There will be a total of four foam
gaskets installed at every module split, two on either side of the unit. As a result, when the
modules are pulled together, the foam gaskets will compress against one another creating an
air seal at the floor wall junction.
STEP 2: Installation of the First Module
Install the first module in its final position on a roof curb, structural support or house keeping
pad, whichever the case may be. The modular pressure plate will always be temporarily in
stalled on one side of the module for ease of installation. Don’t forget to verify if the module
is level and shim the module in consequence, where necessary. See Addendum B for wide
modules (if necessary).
IMPORTANT:
1) Outdoor units must be installed on a level structural steel platforms or roof
curbs. Inspect field conditions to verify mounting surfaces. If the supporting surfaces are not
100% level, then shim the underside of the units to correct the existing condition.
2) Shims (if necessary) or supports should be installed at every 8 feet maximum
interval in both the “X” and “Y” axis and at every module split. Figures 2 and 3 show
the different types of mounting surfaces for indoor units.
STEP 3: The Second Module (figure 7)
Set the second module in place allowing for a certain distance from the first to remove the lift
ing lugs if needed. Relocate the lifting lugs on the side of the unit to provide an anchor point
when bringing the modules together. The lifting lugs will always be installed by the factory on
the longer side of the module. Attach nylon straps to the lifting lugs with a come-along in be
tween to bring both modules together (refer to figure 7). Repeat this for the opposite side of
the unit. Slowly crank the come-along allowing for equal tension on both sides until the mod
ules are completely touching one another.
Aligning the modules (roof) (figure 8)
It is important that the rive-nut holes on the walls and roof are perfectly in line and that t h e
modules are completely touching one another. If the rive-nuts on the roof are not in line
(provided the floor base is properly in line), the problem can be easily corrected by placing ny
lon straps in a diagonal arrangement anchoring one end to the a lifting lug and the other to
the opposite diagonal end of the module lifting lug across the roof (refer to figure 8). The
come-along should be cranked slowly, until the rive-nuts are in line. Proper care must be taken
when performing this operation.
Keeping the modules together (figure 8A)
By reinstalling the lifting lugs on the side of the unit, use threaded rods (not provided by In
genia) to keep the modules compressed against each other.
