NOTE: If unit is located in or above a living space, where

damage may result from condensate overflow, a field−supplied,

external condensate pan should be installed underneath the

entire unit, and a secondary condensate line (with appropriate

trap) should be run from the unit into the pan. Any condensate in

this external condensate pan should be drained to a noticeable

place. As an alternative to using an external condensate pan,

some localities may allow the running of a separate 3/4 inch (19

mm) condensate line (with appropriate trap) per local code to a

place where the condensate will be noticeable. The owner of the

structure must be informed that when condensate flows from

secondary drain or external condensate pan, the unit requires

servicing or water damage will occur. To further protect against

water damage, install a float switch to shut the unit off if the water

in the secondary pan gets too high.

NOTE: To avoid drainage problems, test the primary drain line

by slowly pouring water into the pan. Check piping for leaks and

proper condensate drainage. Using the secondary drain as

explained in the previous note provides further protection against

overflow due to a clogged primary drain.

NOTE: In applications where return air humidity levels stay at

70% or above for a prolonged period of time, condensation can

form on the bottom of pan and drip.

WASTE LINE CONNECTION

If the condensate line is to be connected to a waste (sewer) line,

an open trap must be installed ahead of the waste line to prevent

escape of sewer gases (See Figure 7).

EXPLOSION HAZARD

Failure to follow this warning could result in personal

injury or death.

Provide trap with air gap in drain line when connecting

to waste (sewer) line.

WARNING

Humidifier Application

When installing a humidifier in a system which contains an

N−coil, consideration must be given to location of coil slabs. See

Figure 8.

1. The humidifier should be mounted to the supply plenum or

return duct whenever possible. If necessary, humidifiers

can be mounted to the left side of coil casing. The right side

of the coil casing must not be used to mount the humidifier.

2. Care must be taken to prevent damage of N−coil when

attaching humidifier to coil casing or plenum.

3. Ensure that humidifier has adequate airflow.
