INTRODUCTION
The AHV air handler cabinet uses a 115/208/230V ECM variable-
speed blower motor, with an electronic fan control board. The AHV
may be used for cooling or heat pump applications either with or
without electric heat. The cabinet can be installed in an upflow,
downflow or horizontal position. Refer to Figure 3 and 4.
LOCATION
Select the best position which suits the installation site conditions.
The location should provide adequate structural support, space in the
front of the unit for service access, clearance for return air and supply
duct connections, space for refrigerant piping connections and
condensate drain line connections. If heaters are being installed,
make sure adequate clearance is maintained from supply ductwork;
See Clearances and Warning in Figure 1.

Fire Hazard
Failure to follow this warning could result in
personal injury, death, and/or property damage.
When heaters are installed maintain clearances
from combustible materials as specified on unit
rating plate. Do not use plastic lined or combustible
flexible ducting within 36'' (914 mm) of the supply
end of the modular unit.
If the unit is located in an area of high humidity, nuisance sweating
of casing may occur. On these installations a wrap of 2" (51mm)
fiberglass insulation with a vapor barrier should be used.
HEATER PACKAGES
Factory approved, field installed, UL listed heater packages are
available from the equipment supplier. See unit rating plate for a list
of factory approved heaters (electric heat accessory models EHIA
only). Heaters that are not factory approved could cause damage
which would not be covered under the equipment warranty.
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care
and wear appropriate protective clothing and gloves when
handling parts.
INSTALLATION
The unit is ready to install in any position without modifications.
Refer to the coil instructions for information on drain pan
configurations etc. Make sure coil is set up properly for desired
position of blower cabinet.
Coil must be secured to blower cabinet with the three tabs that are
part of the blower cabinet base. Bend the tabs out from the bottom
so they fit over the coil cabinet.
