Installing the

Auxiliary Drain

Pan

Connecting the Condensate Drain

The auxiliary drain pan ships loose with a fan-coil unit with factory piping. To install the auxiliary drain pan, insert the tabs, located on the side of the drain pan, into the slots located in the chassis end panel. Slide the pan into the narrow groove section to lock into place. See Figures 10 and 11. Make sure the auxiliary pan is pushed all the way into the fully locked position.

Note: The function of the auxiliary drain pan is to collect condensate from the main drain pan and the factory installed piping package only. It also provides a convenient field connection for the condensate drain line for units without factory piping. Moreover, the auxiliary drain pan may not be adequate to collect condensate from a field-installed piping package. Apply additional insulation as needed.

1.De-burr the pipe end before making the connection to the drain pan.

2.Connect a 7/8 inch O.D. copper pipe or tube, with a 0.20 inch wall thickness, 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.

3.Slide the copper pipe over the drain pan nipple and tighten the collar on the pipe with a hose clamp (installer supplied).

Maintain a continuous drain line pitch of 1 inch per 10 feet of drain line run to provide adequate condensate drainage. Extend the drain line straight from the drain pan a minimum distance of 6 inches before making any turns. The installer must provide proper support for the drain line to prevent undue stress on the auxiliary drain pan.

Install a secondary overflow drain line if necessary by punching out the overflow drain nipple on the auxiliary drain pan. Next, place a 3/8
