2. Apply Bulb Gasket
The bulb gasket material creates an airtight
seal between adjacent modules after
connection. The adhesive backing is initially
low tack so the gasket can be easily
repositioned during installation. The
adhesive backing will cure to full bond
strength after 72 hours and will then no
longer be easily removable.

Figure 10 - Applying Bulb Gasket
Each joint in the unit body should have
gasket applied to one side of the opening
separation. That is, only one airway opening
of two adjacent modules should have a
gasket applied.

3. 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 12 - Bolted Base Rail
Use bar clamps or other non-destructive
winching device to pull the tops of the
modules together tightly.
You should now have a fully gasketed,
airtight joint that needs to be permanently
secured into position.
