Condensate Drain Connections
Each unit is provided with 1" evaporator condensate
drain connections (two on each side of the unit for FC
supply fans and one on each side of the unit for DDP
supply fans).
Due to the size of these units, all condensate drain
connections must be connected to the evaporator drain
connections.
Refer to the appropriate illustration in for the location
of these drain connections.
A condensate trap must be installed due to the drain
connection being on the “negative pressure” side of
the fan. Install the P-Traps at the unit using the
guidelines in
Figure 13, p. 34 .

Pitch the drain lines at least 1/2 inch for every 10 feet of
horizontal run to assure proper condensate flow. Do
not allow the horizontal run to sag causing a possible
double-trap condition which could result in condensate
backup due to “air lock”.

Note: Each drain pan connection must be trapped.
The drains may be trapped individually or
connected and then trapped.
Units with Gas Furnace
Units equipped with a gas furnace have a 3/4" CPVC
drain connection stubbed out through the vertical
support in the gas heat section. It is extremely
important that the condensate be piped to a proper
drain. Refer to the appropriate illustration in for the
location of the drain connection.
N No otte e:: Units equipped with an optional modulating gas
furnace will likely operate in a condensing mode
part of the time.
An additional 1–1/4" non-connectable water drain is
located in the base rail within the heating section.
Ensure that all condensate drain line installations
comply with applicable building and waste disposal
codes.
N No otte e:: Installation on gas heat units will require
addition of heat tape to the condensate drain.
Removing Supply and Relief/
Return Fan Shipping Channels
(motors >5 Hp)
Each FC supply fan assembly and relief fan assembly
for S_H_ units shipped with a motor larger than 5 HP is
equipped with rubber isolators (as standard) or
optional spring isolators. Each DDP supply fan
assembly for SAH_ and SXH_ units is equipped with
spring isolators. Each return fan assembly for units
shipped with a motor larger than 5 HP is equipped with
spring isolators. Shipping channels are installed
beneath each fan assembly and must be removed. To
locate and remove these channels, refer to
Figure 16,
p. 37 and Figure 18, p. 39 , and use the following
procedures:
Spring Isolators
See Figure 16, p. 37 through Figure 18, p. 39 for spring
isolator locations.
1. Remove and discard the shipping tie down bolts.
2. Remove the shipping channels and discard.
