INSULATING CONNECTIONS
1. Make sure all exposed lines are well insulated on
towers to conduit, conduit junctions, refrigeration
unit to conduits.
2. To insulate the above, use the leftover conduit
sections and tape.
3. Cut the conduit sections to fit snugly over the
exposed lines and fittings. A little extra time spent
doing a thorough job initially will eliminate a call
back in several days to make corrections.
NOTE: Do not inject foam material directly on the
connections where the tubing connects to the barb
fittings or directly on poly tubing.
4. A can of foam is to be used to fill the openings
between the conduit insulation and the inside
diameter of the floor chases. The purpose is to
provide an air tight seal at the floor level to
prevent foreign matter from entering the chases.
Please read the foam manufacturer’s instructions
carefully. We recommend using the adapter with
the right angle extension.
5. Insert the adapter into the openings
approximately 1" to 2" (2.5 to 5.1 cm) while
depressing the adapter.
6. Move the extension around throughout the area
where the foam is to be placed. Do not over fill,
allow room for expansion. If the chase opening is
too deep insert a section of the leftover conduit
insulation in the opening prior to using the foam
insulation.
