6. ApplicaonInformaon
Coils are designed for indoor installaon only and must be installed
downstream (discharge air) of the furnace. The CAPF/CAPT product
line may be installed in upow or downow orientaons.
7. Condensate Drain Piping
In all cooling applicaons where condensate overow may cause
damage, a secondary drain pan must be provided by the installer
and placed under the enre unit with a separate drain line prop-
erly sloped and terminated in an area visible to the owner. This
secondary drain pan can provide extra protecon to the area under
the unit should the primary drain plug up and overow. For coils
with “A” Cabinets (14” wide), use oat switch if secondary drain
line is not installed. Refer to product nomenclature from product
specicaon literature to idenfy coil models with “A” cabinets.
As expressed in our product warranty, we will not be liable for any
damages, structural or otherwise due to the failure to follow this
installaon requirement.
Condensate drain connecons are located in the drain pan at the
boom of the coil/enclosure assembly. Use the female (3/4” FPT)
threaded ng that protrudes outside of the enclosure for external
connecons. The connectors required are 3/4” NPT male, either
PVC or metal pipe, and must be hand ghtened to a torque of no
more than 37 in-lbs. to prevent damage to the drain pan connecon.
An inseron depth between .36 to .49 inches (3-5 turns) should be
expected at this torque. Insulate PVC drain lines/pipes with high
heat resisve tape within 1” furnace ue/vent pipe. Foil-Masc
Sealant tape is the preferred wrapping material.
1. Ensure drain pan hole is NOT obstructed.
2. To prevent potenal sweang and dripping on nished space,
it may be necessary to insulate the condensate drain line
located inside the building. Use Armaex
®
or similar material.
A Secondary Condensate Drain Connecon, 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.
CAUTION
IF SECONDARY
DRAIN IS
NOT
INSTALLED, THE SECONDARY ACCESS
MUST
BE PLUGGED.

D O NOT USE THE COIL PAN SHIPPED WITH
THE UNIT ON OIL FURNACES
OR
ANY APPLICATION WHERE
THE TEMPERATURE 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 EXCEEDS
300°F.

AILURE
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 boom of
the plasc coil drain pan to have a free ow of air.
A minimum of 2.0” distance from the top of the furnace and the
boom 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.
Figure 1
NOTE: Water coming from the secondary line means the coil pri-
mary drain is plugged and needs immediate aenon.
Install a trap in the drain line below the boom 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 ng.
DO NOT over torque the 3/4” copper connector to the plasc drain
connecon. Using a wet rag or heatsink material on the short piece
to protect the plasc drain pan, complete the drain line installaon.
Use Figure 2 as a template for typical drain pipe roung. This gure
shows how to avoid interference with vent piping.
