When two AcuAir unit sections are drawn together the base
channels of the two sections form an uninsulated cavity that
under certain conditions could produce condensation. AcuAir
provides a ship loose foam insulation kit to ll this cavity as
part of the reconnect procedure.
On the Performance Series air units this insulation must be
injected from underneath the unit after the sections have
been securely joined.
Follow the instructions in the section "FOAM KIT 15 USE
GUIDELINES" on page 21 for preparing the two part foam
mixture and the injection kit. Take special note of the 30
second inactivity limit after which the injection nozzle may
become permanently clogged.
Foam should be injected into the cavity at a rate of 3 - 4
bd-ft per linear foot of seam. This will mean a 15 bd-ft can
of expanding foam will ll between 4 - 5 linear ft of AcuAir
reconnect seam.
