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 5). If using a copper drain line, solder a short piece of

pipe, minimum 6” length, to the connector before installing a

drain fitting.

DO NOT over torque the 3/4” copper connector to the plastic

drain connection. Using a wet rag or heatsink material on the

short piece to protect the plastic drain pan, complete the drain

line installation. Use Figure 6 as a template for typical drain

pipe routing. This figure shows how to avoid interference with

vent piping.
