6 INSTALLATION LOCATION
NOTE: These air handlers are designed for indoor
installation only.
If the unit is located in an unconditioned area with high
ambient temperature and/or high humidity, the air handler
may be subject to nuisance sweating of the casing. On these
installations, a wrap of 2" fiberglass insulation with a vapor
barrier is recommended.
The EEV Series Air Handler product line may be installed in
one of the upflow, downflow, horizontal left or horizontal right
orientations as shown in Figures 3, 4, 5 and 6. The unit may
be installed in upflow or horizontal left orientation as shipped
(refer to specific sections for more information).
Minor field modifications are necessary to convert to downflow
or horizontal right as indicated in below sections.
For DV*FEC installations in areas where the return air envi-
roment sees humidity levels above 65% relative humidity, a
High Humidity Kit (HHK) must be used. See Table 1 for Model
and Kit assignment.

6.1 Upflow Installation

No field modifications are mandatory however to obtain
maximum efficiency, the horizontal drip shield, side drain
pan and drain pan extension, can be removed.
Side Drain Pan and Extension Removal: Refer to Figure
1, remove the two (2) screws that secure the drip shield
support brackets to the condensate collectors (front and
back). Unsnap the side drain pan from the bottom drain
pan using a screw driver or any small lever. The side drain
pan, drip shield brackets and the drain pan extension may
now be removed. From Figure 1, drain port labeled (A)
is the primary drain for this application and condensate
drain line must be attached to this drain port. Drain port
(a) is for the secondary drain line (if used).

6.2 Horizontal Left Installation

No field modifications are permissible for this application.
Drain port labeled (B) in Figure 1 is the primary drain
for this application and condensate drain line must be
attached to this drain port. Drain port (b) is for the sec-
ondary drain line (if used).
In applications where the air handler is installed in the
horizontal left or right position, and the return air envi-
ronment see humidity levels above 65% relative humidity
coupled with total external static levels above 0.5" e.s.p., a
Condensate Management Kit (CMK) is available for field
application. Kit nomenclature can be found in the table 2.

6.3 Downflow/Horizontal Right Installation

IMPORTANT NOTE: In the downflow application, to
prevent coil pan "sweating", the mandatory downflow
kit (DFK) is available through your local Daikin distrib-
utor. The DFK is not supplied with the air handler and
is required to minimize pan sweating on all downflow
installations. See Table 3 for the correct DFK and follow
the instructions provided for installation.
