drain connection.
Close as possible
Figure 16
The manufactured trap shown in Figure 15 allows
for a float switch option to be added.
Refer to the manufacturers data and instructions
for details.
2. The trap must be located within 4 feet of the air
handler drain outlet connection.
3. It
is recommended that a clean-out tee or cross be
installed in the primary drain line for future main-
tenance (See Figure 15 & 16).
4. Do not use reducing fittings in the condensate drain
lines.
5. Slope the drain lines downward a minimum of 1/4"
per foot.
6. Insulate the primary drain to prevent sweating
where pipe temperature could meet or fall below
dewpoint temperatures.
7.
Provide means for drainage to prevent winter
freeze-up of condensate line
.
8. Do not connect the drain line to a closed drain sys-
tem.
9. Use Teflon
®
tape on the air handler drain line con-
nections! Do Not Use pipe joint compound or PVC/
CPVC cement!
It is always recommended that an auxiliary drain pan
be installed under a horizontally installed air handler.
Connect the auxiliary drain line to a separate drain line
(no trap is needed in this line) and terminate according
to local codes.
NOTE: DO NOT use a torch or flame near the plastic
drain pan coupling.
NOTE: DO NOT tighten the drain pipe excessively. Sup-
port the condensate piping and traps outside the unit
to prevent strain on the drain coupling.

LOCK UNIT DISCONNECT SWITCH IN OPEN POSITION
BEFORE SERVICING UNIT. FAILURE TO FOLLOW THIS
WARNING COULD RESULT IN PROPERTY DAMAGE,
PERSONAL INJURY, OR DEATH.
1. These Air Handlers are shipped from the factory
wired for 230 volts. The units may be wired for 208
volts. Follow instructions on unit wiring diagram lo-
cated on blower housing and in the Service Facts
document included with the unit.
2. The selection of wire and fuse sizes should be made
according to the Minimum Branch Circuit Ampacity
and the Maximum Overcurrent Device listed on the
unit nameplate.
3. Field wiring diagrams for electric heaters and unit
accessories are shipped with the accessory.
4. Wiring must conform to National and Local codes.
5. Ground unit per local codes with good safety proce-
dures.
If an electric heater is not installed, the Knockout Plate pro-
vided in the Accessory Kit MUST be installed on the air han-
dler and the conduit terminated to it. The electrical connec-
tions are made using the two power leads and ground wire
connections which are located near the discharge of the
blower.
Openings where the field wiring enters the
cabinet must be completely sealed. Location of power
entry is shown on the outline drawing. Use 2.5" clear
stickers to seal all unused electrical knockouts.
NOTE: If air handler is used with or without a heater,
the electrical entry hole as well as any other cabinet
penetrations must be sealed air-tight.
