Condensate Drain Piping

A 3/4-inch female NPT condensate drain connection is provided on the evapo-
rator access panel end of the unit. Provide a trap and fill it with water before 
starting the unit to avoid air from being drawn through. Follow local codes and 
standard piping practices when running the drain line. Pitch the line downward 
away from the unit. Avoid long horizontal runs. See Figure 5, below.

NOTE:  Do not use reducing fittings in the drain lines

 
The condensate drain must be:

  

Made of 3/4" pipe size.

  

Pitched 1/4" per foot to provide free drainage to conve 

 

nient drain system.

  

Trapped.

  

Must not be connected to a closed drain system unless  

 

the trap is properly vented.

Table 1. Determine Filter Size

*Filters must be installed in the return air system.  The above square footages 
are based on 300 F.P.M. face velocity.  If permanent filters are used, size per 
mfg. Recommendation with clear resistance of 0.05"WC.

Air Filters

These units require filters with adequate filter area be provided in the return air 
duct.  Table 2 below gives filter data.  The specific location of the filters depends 
on the type of installation and the layout of the duct system.  Be sure the owner 
is aware of the location of the filter and the need to change them as required.  
The Filter Size (Sq. Ft.) are based on 300 F.P.M. face velocity. If permanent 
filters are used, size per mfg. recommendation with clean resistance of .05" WC.
