Goodman UPFLOW Installation Instructions Manual page 2

5.2 Clearances
Refrigerant lines must be routed depending on configura-
tion of unit to maintain the required 24" minimum clearance
for service. Consult all appropriate regulatory codes prior to
determining final clearances. 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.
6. Application Information
Coils are designed for indoor installation only and must be
installed downstream (discharge air) of the furnace. The
CAPTA product line may be installed in upflow or downflow
orientations.
7. Condensate Drain Piping
In all cooling applications where condensate overflow may
cause damage, a secondary drain pan must be provided by
the installer and placed under the entire unit with a separate
drain line properly sloped and terminated in an area visible
to the owner. This secondary drain pan can provide extra
protection to the area under the unit should the primary drain
plug up and overflow. For coils with "A" Cabinets (14" wide),
use float switch if secondary drain line is not installed. Refer
to product nomenclature from product specification literature
to identify coil models with "A" cabinets. As expressed in our
product warranty, we will not be liable for any damages, struc-
tural or otherwise due to the failure to follow this installation
requirement.
Condensate drain connections are located in the drain pan at
the bottom of the coil/enclosure assembly. Use the female (3/4"
FPT) threaded fitting that protrudes outside of the enclosure
for external connections. The connectors required are 3/4"
NPT male, either PVC or metal pipe, and must be hand tight-
ened to a torque of no more than 37 in-lbs. to prevent damage
to the drain pan connection. An insertion depth between .36
to .49 inches (3-5 turns) should be expected at this torque.
Insulate PVC drain lines/pipes with high heat resistive tape
within 1" furnace flue/vent pipe. Foil-Mastic Sealant tape is
the preferred wrapping material.
1. Ensure drain pan hole is NOT obstructed.
2. To prevent potential sweating and dripping on finished
space, it may be necessary to insulate the condensate
drain line located inside the building. Use Armaflex
similar material.
A Secondary Condensate Drain Connection, now called for
by many building codes, has been provided. Pitch the drain
line 1/4" per foot to provide free drainage. Provide required
support to drain line to prevent bowing. Install a condensate
trap in the primary drain line to ensure proper drainage. If
the secondary drain line is required, run the line separately
from the primary drain and end it where condensate discharge
can be easily seen.
IF SECONDRY DRAIN IS NOT INSTALLED, THE SECONDARY
ACCESS MUST BE PLUGGED.
8. Plastic Drain Pan Application
DO NOT USE THE COIL PAN SHIPPED WITH THE UNIT ON OIL
FURNACES OR ANY APPLICATION WHERE THE TMPERATURE
OF THE DRAIN PAN MAY EXCEED 300°F. A HIGH TEMPERATURE
DRAIN PAN SUCH AS KITS HTP-A, -B, -C, AND -D FOR NORMAL
CABINET WIDTHS OF 14, 17.5, 21 AND 24.5 INCHES,
RESPECTIVELY, SHOULD BE USED FOR APPLICATIONS WHERE
THE TEMPERATURE EXCEEDS 300°F AND BELOW 450°F. A FIELD
FABRICATED METAL DRAIN PAN CAN ALSO BE USED FOR
APPLICATIONS WHERE TEMPERATURE EXEEDS 300°F. FAILURE
TO FOLLOW THIS WARNING MAY RESULT IN PROPERTY
DAMAGE AND/OR PERSONAL INJURY.
If the uncased coil is to be installed on top of a gas furnace,
allow enough space between the top to the furnace and the
bottom of the plastic coil drain pan to have a free flow of air.
A minimum of 2.0" distance from the top of the furnace and
the bottom of the coil pan is required.
NOTE: The coil must be installed with the line set and drain
openings to the front of the furnace.

NOTE: Water coming from the secondary line means the
coil primary drain is plugged and needs immediate attention.
Install a trap in the drain line below the bottom of the drain
pan (Figure 1). If using a copper drain line, solder a short
piece of pipe, minimum 6" length, to the connector before
installing a drain fitting.
