Interconnecting Tubing; Clearances; Horizontal Applications; Installation Location - Daikin DV PTC 14 Series Installation Instructions Manual

5.3 Interconnecting Tubing

Give special consideration to minimize the length of refrigerant
tubing when installing air handlers. Refer to Remote Cooling/
Heat Pump Service Manual RS6200006, and TP-107 Long Line
Set Application R-410A for tubing guidelines. If possible, allow
adequate length of tubing such that the coil may be removed
(for inspection or cleaning services) from the cabinet without
disconnecting the tubing.

5.4 Clearances

The unit clearance from a combustible surface may be 0".
However, service clearance must take precedence. A minimum
of 24" in front of the unit for service clearance is required.
Additional clearance on one side or top will be required for
electrical wiring connections. Consult all appropriate regulatory
codes prior to determining final clearances. When installing
this unit in an area that may become wet (such as crawl
spaces), elevate the unit with a sturdy, non-porous material. In
installations that may lead to physical damage (i.e. a garage) it
is advised to install a protective barrier to prevent such damage.
Always install units such that a positive slope in condensate line
(1/4" per foot) is allowed.

5.5 Horizontal Applications

If installed above a finished living space, a secondary drain pan
(as required by many building codes), must be installed under
the entire unit and its condensate drain line must be routed to a
location such that the user will see the condensate discharge.

6 Installation Location

NOTE: These air handlers are designed for indoor installation
only.
The DV**PTC*14** product line may be installed in one of the
upflow, downflow, horizontal left or horizontal right orientations as
shown in Figures 2, 3, 4 and 5. 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.

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).
1. If the side drain pan is removed, the drain port opening in
the access panel must be covered by the accessory drain
port plug (DPK1) as shown in figure 1.1.

6.2 Horizontal Left Installation

No field modifications are permissible for this application.
The bottom right drain connection is the primary drain for
this application and condensate drain line must be attached
to this drain connection. The top connection of the three
drain connections on the drain pan must remain plugged for
this application. The bottom left drain connection is for the
secondary drain line (if used).
In applications where the air handler is installed in the horizontal
left position, and the return air environment see humidity levels
above 65% relative humidity coupled with total external static
levels above 0.5" e.s.p., a condensate kit is available for field
application. Kit nomenclature can be found in Table 1.
