COVER RETURN GRILLE DURING CONSTRUCTION.
IMPORTANT!
Unless the ductwork is to be installed after all construction dusts have been
removed, care should be taken to prevent dust from entering the ducts,
especially the return duct
. If concrete or plaster dusts are allowed to enter
the unit, they may permanently bind to the coil surfaces, reducing airflow and
heat transfer. Filters will not prevent this.
If concrete, plaster work, or cleanup will be ongoing after the return duct
is installed, tape paper or plastic sheeting over the return grille(s) to
prevent dust from entering the duct. The DRY-O-TRON
®
must be OFF
until all dusts are removed. Remove the cover only after all concrete and
plaster work is complete and the dusts have been cleaned up and
removed.
Do not operate the unit when dust
s are present or while the grille
cover is still in place.
Important!
Never use the DRY-O-TRON
®
as a construction-site dehumidifier,
cooler, or heater. Do not operate the unit while construction dusts
are present.
