2. Determine on which side of furnace the condensate disposal line is to be run (NOTICE: On
CHX1/CDX1's this must be the same side as the flue outlet or bottom of unit). Attach the condensate
trap to the furnace casing using the #8x3/4" sheet metal screws provided in the parts package. Pilot
holes are provided on both sides of the casing for mounting.
NOTE: When the CDX1 series unit is used in a horizontal application, the drain hose from the
collector box will require a location change from it's factory shipped connection. A knockout has
been provided in the unit side casing for the drain hose to exit. The connection change can be
accomplished as follows: Refer to Figure 16.
a) Locate and disconnect the drain hose at the collector box from its factory shipped connection
location.
b) Locate and uncap the drain at the bottom (as it is oriented) of the collector box.
c) Connect the drain hose from step a to the uncapped bottom drain from step b.
d) Cap the previous drain connection from step a with the existing cap removed in step b.
3. Attach the drain hose (11/16" diameter clear tubing) from the front (CHX1) or bottom (CDX1) of the
condensing coil cover plate to one side of the PVC tee provided in the trap assembly. Secure the
drain hose (11/16" o.d. tubing) with the silver clamp provided in the parts package. Be careful to route
the tubing through the proper hole in the furnace casing using the Heyco bushing provided. While
making all connections with the clear tubing, be careful to route the tubing in a manner to prevent
kinking or abrasion of the tubing.
