Condensate Piping

This unit is designed for either right- or left-side exit of

condensate piping. Route the condensate drainiine only within the conditioned space: this prevents possible

freezing of the condensate, which would block the drain- line. Use an electric heat cable if you route the conden- sate line through unconditioned areas.

A CAUTION

1 - Determine which side condensate will exit the unit.

2- Connect 1/2 inch (13 mm) plastic pipe plug (pro- vided) in the unused end of the condensate trap. Install plug so that it is sealed water tight yet able to be removed. Do not permanently seal the connec- tion. Teflon tape is recommended to seal joint. See figure 21.

3 - Use the provided condensate drain adapter (3/4" x

1/2") and a field-providednipple to carry drainage outside the cabinet. If a fieldsubstitute is needed, 1/2 inch CPVC x 1/2 inch MPT adapter and 1/2 inch CPVC is acceptable for use.

4 - Glue nipple to the adapter using the procedures out- lined in the "Joint Cementing Procedures" section. The nipple/adapter assembly should be connected in a non-permanentmanner and must be water tight. Teflon tape is recommended to seal the joint.

For Right-Hand Side Condensate Exit:

Install the nipple/adapter assembly from the out- side of the cabinet and insert the adapter intothe threaded opening in the condensate trap.

For Left-Hand Side Condensate Exit:

Insert nipple/adapterassembly from the left hand side of the cabinet and through the combustion air inducer mounting structure into the threaded opening in the condensate trap.

5 - Connect field-supplied plumbing to nipple and route to open drain. Plumbing should be vented to a point higher than the condensing coil. See figure 22.
