NOTE: When connecting condensate drain lines, avoid blocking
filter access panel, thus preventing filter removal. After connection,
prime both primary and secondary condensate traps.
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 use of a separate 3/4-in (19 ram) condensate line
(with appropriate trap) to a place where the condensate will be
noticeable. The owner of the structure must be informed that when
condensate flows from the secondary drain or external condensate
pan, the unit requires servicing or water damage will occur.
Install traps in the condensate lines as close to the coil as possible.
(See Fig. 21.) Make sure that the outlet of each trap is below its
connection to the condensate pan to prevent condensate from
overflowing the drain pan. Prime all traps, test for leaks, and
insulate traps if located above a living area. Condensate drain lines
should be pitched downward at a minimum slope of l-in (25 ram)
for every 10-fl (3 m) of length. Consult local codes for additional
restrictions or precautions.
Step 8 -- Accessories
A. Electronic Air Cleaner
The Electronic Air ('leaner may be connected to fan coil as shown
in Fig. 23. This method requires a field supplied transformer. See
Electronic Air Cleaner literature for kit requirements.
B. Humidifier
Connect humidifier and humidistat to fan coil unit as shown in Fig.
24 and Fig. 25. The cooling lockout relay is optional.
