• Drain line must be no smaller than drain pan outlet and ade-
quately sized to accommodate the condensate discharge
from the unit.
• Drain line should slope away from unit a minimum of 1/8”
per foot to ensure proper drainage.
• Drain line must be routed to an acceptable drain or outdoors
in accordance with local codes.
• Do not connect condensate drain line to a closed sewer
pipe.
• Drain line may need insulation or freeze protection in certain
applications.
XI. CONDENSATE DRAIN, OUTDOOR COIL
The outdoor coil during heating operation will sweat or run water
off. The outdoor coil will also run water off during the defrost
cycle. See Section VI, Installation, Page 13 for mounting precau-
tions.
XII. ELECTRICAL WIRING
Field wiring must comply with the National Electrical Code
(C.E.C. in Canada) and local ordinances that may apply.
A. POWER WIRING
1. This unit incorporates single-point electrical connections
for the unit and electric heat accessory.
2. It is important that proper electrical power is available to
the unit. Voltage should not vary more than 10% from the
values marked on the unit rating plate. Phase voltages
must be balanced within 3%.
3. Install a branch circuit disconnect within sight of the unit.
Use the unit rating plate or heater kit tables to determine
the required size.
4. The branch circuit wire must be sized in accordance with
the National Electrical Code (C.E.C. in Canada) and local
ordinances that may apply using the minimum circuit
ampacity found on the unit rating plate.
5. Field-installed power wiring must be run through ground-
ed rain-tight conduit attached to the unit power entry
panel and connected as follows:
UNITS WITHOUT ELECTRIC HEAT - Connect power
wiring to the power terminal block located on the left side
of the electric heat compartment. Connect the ground
wire to the adjacent ground lug (see Figure 15).
UNITS WITH FACTORY INSTALLED ELECTRIC HEAT -
Connect power wiring to the power terminal block located
on the electric heater kit (see Figure 16). Connect the
ground wire to the adjacent ground lug. DO NOT connect
aluminum wiring directly to the electric heater terminal
block. Wiring to the unit contactors is factory-connected.
6. For field installation of an electric heater kit, follow the
instructions below. Refer to the information supplied with
the kit.
a. Removing screws as required, open heater access
door and detach adjacent power entry panel.
b. Remove wires to unit contactor (1L1, 1L2, 1L3) from
unit terminal block on the left side of the electric heat
compartment. Remove and discard the terminal block
and the adjacent ground lug.
c. Remove the heater kit block-off panel and install the
heater kit in its place using 9 of the 12 screws previ-
ously removed.
d. Connect the unit contactor wires (1L1, 1L2, 1L3) to the
compressor fuse block on the heater kit.
e. Re-install the power entry panel & run conduit and the
proper size field wiring through the opening in the
panel.
f. Connect field wiring to the power terminal block located
on the electric heater kit. Connect ground wire to the
adjacent ground lug.
g. Connect heater kit control plug to the receptacle on the
control wiring harness.
h. Close heater access door and secure with screws pre-
viously removed.
B. CONTROL WIRING (Class II)
1. Low voltage wiring should not be run in conduit with
power wiring.
2. Control wiring is routed through the 7/8" hole in the unit
side panel. See Figure 2. Use a minimum #18 AWG ther-
mostat wire. For wire lengths exceeding 50', use #16
AWG thermostat wire. Connect the control wiring to the
low voltage terminal block located below the unit control
box.
3. It is necessary that only approved heat pump thermostats
be used. Please contact your distributor for part number
information. See thermostat specification catalog for rec-
ommended thermostats.
4. Figure 17 shows representative low voltage connection
diagrams. Read your thermostat installation instructions
for any special requirements for your specific thermostat.
C. INTERNAL WIRING
1. A diagram of the internal wiring of this unit is located on
the inside of the control access panel and in this manual.
If any of the original wire must be replaced, the wire
gauge and insulation must be the same as original wiring.
Transformer is factory-wired for 230 volts on 208/230 volt
models and must be changed for 208-volt applications.
See unit wiring diagram for 208 volt wiring.
