NOTICE: It is a requirement of the International
Mechanical Code (307.2.3) to install a secondary drain
or an auxiliary drain pan where damage to any
building components will occur as a result of
overflow from the equipment drain pan or stoppage in
the condensate drain piping from a cooling or an
evaporator coil. Follow local code requirements.
Refer to Figure 2.2 and 2.3 for primary and secondary
condensate drain locations. Components for the PVC
condensate trap are provided in a separate bag with fan
coil unit (see Figure 2.14) and should be cemented
together with PVC pipe cement.
Do not use substitute trap. Do not cut
off or alter trap components.
Thread male adapter (see Figure 2.14) into unit’s primary
condensate drain connection. Assemble and cement
remaining components together. Then cement assembly
to male adapter. The 45° elbow provides an offset from
beneath unit suction line for access to clean-out plug.
Run a condensate line from the trap to a suitable drain
that’s in accordance with local codes. Make sure the line
is pitched 1/4" per foot.
NOTICE: The secondary drain connection requires
field supplied components to complete installation.
Follow local code requirements.
NOTICE: Never connect condensate line to a closed
drain system.

Step 7: Installing Air Distribution
Components
All plenum duct and supply tubing runs as well as room
terminator locations must be in accordance with air
distribution system requirements listed in Section 1 of
this manual. Where taping of joints is required, UL181
approved tape is required.
Plenum Duct Installation
All tees, elbows and branch runs must be a minimum of 18"
from the fan coil unit or any other tee, elbow or branch run.
Keep all tees and elbows to a minimum to keep system
pressure drop on larger layouts to a minimum.
