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.
WARNING
WHEN DRILLING INTO CONCRETE, EYE PROTECTION
IS RECOMMENDED AT ALL TIMES.
If you will install the unit on a wall-mounted bracket,
do the following:
CAUTION
Make sure that the wall is made of solid brick, concrete,
or of similarly strong material.
The wall must be able to
support at least four times the weight of the unit.
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.
Step 4: Connect signal and power cables
The outside unit's terminal block is protected by
an electrical wiring cover on the side of the unit. A
comprehensive wiring diagram is printed on the inside of
the wiring cover.
WARNING
BEFORE PERFORMING ANY ELECTRICAL OR
WIRING WORK, TURN OFF THE MAIN POWER TO
THE SYSTEM.
1. Prepare the cable for connection:
USE THE RIGHT CABLE
• Indoor Power Cable (if applicable): H05VV-F or
H05V2V2-F
• Outdoor Power Cable: H07RN-F
• Signal Cable: H07RN-FF
CHOOSE THE RIGHT CABLE SIZE
The size of the power supply cable, signal cable, fuse,
and switch needed is determined by the maximum current
of the unit. The maximum current is indicated on the
nameplate located on the side panel of the unit. Refer to
this nameplate to choose the right cable, fuse, or switch.
a. Using wire strippers, strip the rubber 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.
WARNING
ALL WIRING WORK MUST BE PERFORMED
STRICTLY IN ACCORDANCE WTH THE WIRING
DIAGRAM LOCATED INSIDE OF WIRE COVER OF
THE OUTDOOR UNIT.
2. Unscrew the electrical wiring cover and remove it.
3. Unscrew the cable clamp below the terminal block
and place it to the side.
4. Connect the wire according to the wiring diagram, and
firmly screw the u-lug of each wire to its corresponding
terminal.
5. After checking to make sure every connection is
secure, loop the wires around to prevent rain water
from flowing into the terminal.
6. Using the cable clamp, fasten the cable to the unit.
Screw the cable clampd down tightly.
7. Insulare unused wires with PCV electrical tape.
Arrange them so that they do not touch any electrical
or metal parts.
8. Replace the wire cover on the side of the unit, and
screw it in place.
