2.5 Quiet Installation
Remove Shipping Restraints
The compressor is attached to the cabinet with two
cable ties to secure it during shipment. This rigid
attachment is not necessary once the unit is installed
and may cause noise from compressor vibration.
AFTER INSTALLATION, CUT THE CABLE TIES TO
FREE THE COMPRESSOR FROM THE CABINET.
REMOVE THE HORIZONTAL CABINET SUPPORT
TO WHICH THE COMPRESSOR IS ATTACHED. The
ends of the support are notched so that the support can
easily be removed. Cut the strips of metal on each end
and remove the support section from the cabinet. This
will prevent the compressor from transmitting vibration
to the cabinet.
Make sure none of the compressor tubes are pressed
against the cabinet or access panel. Check that the
compressor tubes are centered in the holes where they
pass through the drain pan.
A length of 10 feet or more of acoustical flex ducting on
the outlet of the DHV-150H will reduce air noise from
the fan. A length of flexible ducting on all DHV-150H
duct connections is recommended to reduce noise and
vibration transmitted to rigid ductwork in the structure.
