REASSEMBLY
• Insure that fi nal location is fl at and
level over the entire area of the unit
foot print. If not fl at and level the unit
base must be leveled by shimming.
This will allow all doors and dampers
to operate properly after reassembly.
• Sort and inspect all gasketed parts
and replace any gaskets that have been
damaged.
• It is recommended for units that
were shipped in sections having ship-
ping splits, that the entire unit be as-
sembled as one piece not in individual
sections.
• If any raceways were separated, use
construction grade sealant (caulking)
to rejoin the foam insulation inside
the raceways as they are reassembled.
However, if any volume of foam in-
sulation was destroyed or lost, replace
it with canned spray foam after reas-
sembly is complete.
