eLeCTRICAL WIRIng
Site preparation for Wiring
Electrical wiring must be in accordance with all electrical
codes. In absence of such requirements to the National
Electrical Code (NEC).
WARnIng
Electrical shock hazard. Turn OFF electrical power
supply before making electrical connections. Failure
to do so could result in death or serious injury.
!
1.
Check unit rating plate for circuit ampacity and breaker
or time delay fuse size. Use only HACR type breakers.
Select proper wire for ampacity rating.
2.
Each unit must have separate branch circuit protected
by time delay fuse or breaker. Refer to unit rating plate
for proper wire and breaker or time delay fuse size.
3.
Inspect existing wiring for any defects such as cut or
frayed wires. Replace if any such wiring if found.
4.
Remove left end cap of unit to access wiring diagram
and electrical wiring. Remove three screws. See
Figure 15
.
5.
Rotate louver down to expose third screw. See
Figure 16
6.
Slide left end cap off to expose control box. locate
wiring diagram on inside of end cap. See Figure 17
.
Units rated 208/230v, primary side of transformer is factory
wired for 230v.
For 208v power supply, transformer tap must be changed
from orange to red.
Refer to wiring diagram located inside of left end cap of
unit.
Connect Wiring
Remove screw on front of control box to access high and
low volt wiring. See Figure 18, Page 14
.
High Voltage electrical Wiring
1.
Refer to wiring diagram. Connect power wire to Black
l1 and White wire l2 at power connector location.
See
Figure 18, Page 14
.
2.
Connect ground wire to ground lug or lead at same
location in control box.
3.
Terminate all unused wires with wire nut or crimp
connector.
Low Voltage Electrical Wiring
24v control transformer is located in the air handler
providing low volt control power to both air handler and
condenser.
low voltage interconnect wiring must be at least 18 AWG.
