The standard supply-air discharge for vertical units (model
DSV-xxx) is vertically upward.
Some vertical units may have ports allowing supply air to exit
through the top or right side. Where this is the case, select the
best port for the installation. It may be possible to eliminate an
otherwise-required duct elbow near the unit. Cover the unused
port with the blank cover.
Other adjustments, including adjustments to the blower, may
be necessary. Open the front-middle access panel and/or the
rear-top access panel to view the blower arrangements. Be sure
air will flow in the proper direction.
