Connect Modules
Modules are to be connected with nuts and
bolts through the base rail and with metal
strapping over module joints. Metal straps
have adhesive backs and are to be
additionally fastened to the unit case with
sheet metal screws. All connection hardware
is shipped with the unit.
Align modules and insert bolts through the
bolt holes in the base rails of two adjacent
modules. Secure with nuts to pull the bases
of the two modules together tightly.
Figure 11 - Bolted Base Rail
Use bar clamps or other non-destructive
winching device to pull the tops of the
modules together tightly.
Figure 12 - Bar Clamp
There should now be an airtight joint that
needs to be permanently secured in position.

Secure Module Joints
The metal straps are to be used to secure
module joints in order to maintain the
airtight seal. Straps are provided with pre-
drilled holes and adhesive backing already
affixed. Self-tapping sheet metal screws are
provided to attach the straps to the unit
cabinet.
Leave bar clamps in place until strap is
secure.
Peel away backing from adhesive side of a
strap.
Place the strap over a module joint with the
adhesive side of the strap against the unit
case.
Ensure that strap completely covers the joint
and that it is square with the unit casing.
Apply pressure to the strap to affix the
adhesive and to hold strap in place.
Insert self-tapping screws through pre-
drilled holes in strap and secure screws into
unit casing using a power drill. For best
results, use the lowest effective power drill
torque setting. Be careful not to over tighten
the screws.
Remove bar clamps and repeat for all
remaining module joints.
