Tightening Connection
• Align the center of the pipes.
• Sufficiently tighten the flare nut with fingers, and then tighten it
with a spanner and torque wrench as shown in Fig.16 & 17.

WARNING caution
• Excessive torque can break the nut or flared pipe and cause
a leak, and too low torque can also cause a leak. Follow the
specified torque and use a torque wrench as required.
• When flared joints are reused, the flare part shall be
re-fabricated.
• Neatly run the refrigeration pipe from the indoor unit
connection to the outdoor unit suction and discharge
connections. Follow the same flaring procedure outlined
above to flare and connect the suction and discharge pipes to
the outdoor unit accordingly.
Insulating the pipes
Wrap suitable insulation material (supplied by the installer) separately
around each individual refrigeration pipe, the suction and discharge
pipes must not be in direct contact. Ensure that the flare connections
are covered, then wrap the insulated pipes with vinyl tape.
Attach the interconnecting electrical cable and drain pipe to
the pipe assembly with narrow vinyl tape, then wrap the whole
assembly with wide vinyl tape starting from top to bottom, as
pictured in the diagram below.
Finally plug the hole in the wall using gum type sealer.

Outdoor unit electrical connection
1. Check that power supply to the air conditioner circuit is off
2. Confirm that power cable with suitable rating for the air
conditioner current rating has been run from the circuit breaker
to the isolation switch, according to AS/NZS 3000 & local
wiring rules.
3. Run power supply cable from the isolation switch to the
outdoor unit terminal block area. Also run the interconnecting
cables from the indoor unit to the outdoor unit terminal
block area. All exposed power cables must be protected, for
example in conduit.
4. Remove the terminal block cover and loosen the cable clamp
as shown in figure 18.
Fig. 18
5. Connect the interconnecting cable from the indoor unit to the
terminal block following the wiring diagram provided on the
following page, ensuring that the colours match between
indoor unit and outdoor unit.
6. Connect the main power supply cables from the isolation
switch to the outdoor unit terminal block following the wiring
diagram.
7. Ensure that the terminal block screws are secure by gently
pulling the wires.
8. Fit the cable clamp over the incoming wires to protect from
strain, then fit the cover and fix in place with the screw.
