CAUTION
Precautions when laying power wiring
Use round pressure terminals for
connections to the power terminal block.
When none are available, follow the
instructions below.
• Do not connect wiring of different
thicknesses to the power terminal
block. (Slack in the power wiring may
cause abnormal heat.)
• When connecting wiring which is the
same thickness, do as shown in the
figure below.
• For wiring, use the designated power
wire and connect firmly, then secure to
prevent outside pressure being exerted
on the terminal block.
• Use an appropriate screwdriver for
tightening the terinal screws. A
screwdriver with a small head will strip
the head and make proper tighterning
impossible.
• Over-tightening the terminal screws
may break them.

Flaring Work
Main cause for gas leakage is due to defect of
flaring work. Carry out correct flaring work in
the following procedure.
1
Use the piping kit accessory or the pipes
purchased locally.
2
Measure the distance between the indoor
and the outdoor unit.
3
Cut the pipes a little longer than measured
distance.
4
Cut the cable 1.5m longer than the pipe
length.
1. Completely remove all burrs from the cut
cross section of pipe/tube.
2. While removing burrs put the end of the
copper tube/pipe in a downward direction
while removing burrs location is also
changed in order to avoid dropping burrs
into the tubing.
