Final Drain Installation
Unit Drain Installation
NOTE: Failure to follow the following procedures may result in serious property damage. A field supplied secondary
condensate pan may be required. Check with local codes. In case of drainage system blockage, the unit base will allow
excess water to flow out of the unit through the plenum and the architectural louver. It is critical to ensure that the drain-
age path is not blocked or obstructed in any way during installation.
1)
The supplied drain kit must be connected to one of the two (left or right) 3/4" FPT connections on
the unit base-pan.
2)
Insert the provided 3/4" nipple into the determined connection using field-supplied Teflon tape or pipe joint
compound.
3)
With the slip end of a 3/4" union, connect to the nipple with Teflon tape or pipe joint compound.
4)
Hand-tighten all fittings to prevent damage to unit or fittings.
5)
Install a field-supplied drain system to the slip end of the union. A trap is required and drain connections
should be connected to building DWV system. Pitch the drain line of a 1/4" downward slope for every foot (1') of
lateral horizontal run to the DWV.
6)
Plug the unused connection port with the provided 3/4" pipe plug and field-supplied Teflon tape or
pipe joint compound. High tighten to prevent damage to the unit or fittings. Do not thread metal or copper pipe
fittings directly into unit.
7)
Check the system for leaks.
