outside or attach it to a secure metal wall bracket or
pad.
Carefully roll the excess tubing and place it behind the
condenser.
Attach the bundle connections to the outside
condenser.

Remove the electrical cover.
CAUTION: At this point, be sure you know if your unit is
the 110 volt or the 220 volt. Connecting incorrect
voltage to the unit will cause serious damage to the
system and void the warranty.
Allow a certified electrician to supply power to the unit
in accordance with all municipal, state, and federal
regulations that may apply.
If the unit is the 110 volt system, hook to terminal
__L1__ and ___N_ , and ground.
If the unit is the 220 volt system, attach to terminals
__L1__ and __L2_ , and ground.
STEP 6
Attach the air handler plug to the communication plug
on the system.
Push firmly over the wire harness on the condenser to
ensure the quick connect is solid.
You will need a Phillips screwdriver to attach the green
ground wire to the condenser.

Using the 2 open wrenches,
screw the quick connect
components together. One
will tighten the connection
and the other will hold the
opposing side to prevent the
copper from twisting. Failing
to use the appropriate tools
during installation may void
the warranty.
Take care and ensure you use two wrenches for this
task. If you use only one open wrench, the connection
to the outside condenser will fail to be sufficiently tight.
This may cause the soft copper to bend and leak.
