Preferred connection is to the auxiliary drain pans
Connect a 3/4-inch I.D. rubber or plastic hose to the auxiliary drain pan.
This should be a mechanical connection that allows easy removal of the auxiliary drain pan when servicing the piping end pocket.
Slide the hose over the drain pan nipple and tighten the hose on the nipple with a hose clamp (installer supplied).
Maintain a continuous drain line pitch of one inch per ten feet of drain line run to provide adequate condensate drainage. Extend the drain line straight from the drain pan a minimum distance of six inches before making any turns. The installer must provide proper support for the drain line to prevent undue stress on the auxiliary drain pan.
- Connect directly to the main drain pan (Less preferred)
- Stainless steel main drain - 3/4" Threaded connection
- (Polymer main drain - not preferred)
