bracket , do the following:
1.Mark the position of bracket holes based on
dimensions chart.
2. Pre-drill the holes for the expansion bolts.
3. Place a washer and nut on the end of each
expansion bolt.
4. Thread expansion bolts through holes in
mounting brackets, put mounting brackets
in position, and hammer expansion bolts into
the wall.
5. Check that the mounting brackets are level.
6. Carefully lift unit and place its mounting feet
on brackets.
7. Bolt the unit firmly to the brackets.
8.
If allowed, install the unit with rubber
gaskets to reduce vibrations and noise.
If you will install the unit on the ground or
on a concrete mounting platform, do the
following:
1. Mark the positions for four expansion bolts
based on dimensions chart.
2. Pre-drill holes for expansion bolts.
3. Place a nut on the end of each expansion bolt.
4. Hammer expansion bolts into the pre-drilled
holes.
5. Remove the nuts from expansion bolts, and
place outdoor unit on bolts.
6. Put washer on each expansion bolt, then
replace the nuts.
7. Using a wrench, tighten each nut until snug.

jacket from both ends of cable to reveal
about 40mm (1.57in) of the wires inside.
b. Strip the insulation from the ends of the
wires.
c. Using a wire crimper, crimp u-lugs on the
ends of the wires.
PAY ATTENTION TO LIVE WIRE
While crimping wires, make sure you clearly
distinguish the Live (“L”) Wire from other wires.
