Uncrate and Inspect the Unit Ventilator(s)
Carefully remove the packaging, remaining alert to any signs of
shipping damage. Be careful not to discard components that may
be included with the packaging. (You may want to retain some or
all of the packaging to provide job site unit location information
and temporary protection for the unit ventilator after installation.)
Be sure to dispose of plastic packaging and protective cardboard
properly, in accordance with local recycling rules and guidelines.
If unit is damaged, file a claim with the carrier. Notify the local
Daikin Unit Ventilator representative immediately.
Properly Identify Unit Ventilator(s)
To be sure the correct unit ventilator(s) is/are installed in the
correct location(s), the installer must check the packing list and
unit identification/tagging number(s) against the plans.
Further, the

Wall Openings, Louvers, and VentiMatic™ Shutter
Prior to unit installation, be sure that the exterior wall openings and
louvers, as applicable, are ready and in accordance with the job plans.
Horizontal Ceiling Models AHF, AHB, AHV and AHR ceiling
units are typically installed in the ceiling with a variety of
exposures, including completely exposed, partially exposed,
partially or fully recessed, or completely concealed, (see
). Each installation should contain a properly sized louver
that is designed to let in fresh air while preventing water (such
as rain) from getting past the louver and into the unit itself.
A weather-tight seal keeps unwanted air and moisture from
entering the occupied space. Follow typical installation methods
for louvers / VentiMatic Shutter and flashing by others to prevent
moisture and air infiltration damage.
Accessibility to fully recessed units should be considered, see

Before hanging the unit ventilator in place, if it is a cooling unit,
check the condensate drain hand connection to be sure it is the
same as the cooling coil hand of connection, and that it agrees
with the drain stub-up. If necessary, move condensate drain
cap to the opposite end. Drain pan can be sloped in direction
of drain connection. Do not discard drain cap (
). Drain
pan slope can be field adjusted front-to-back and left-to-right by
removing and re-setting the adjustment screws on each side of
the pan adjustment bracket.
