Figure 16. TRAP ASSEMBLY MOUNTED ON CDX1 RIGHT SIDE HORIZONTAL INSTALLATION
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.
