OPERATION

15.1. Pre-run checks

CAUTION

1.

In case the use of stranded conductor wires is
unavoidable for one reason or another, make sure to
install round crimp-style terminals on the tip.
Place the round crimp-style terminal on the wire up to
the covered part and fasten the terminal with the
appropriate tool.

2.

When connecting the connection wires to the terminal
board using a single core wire, be sure to perform
curling.

Not executing the connections properly may cause
heat and fire.
Strip the wire at terminal block:

Excessive strip length may cause electrical 
shock or leakage.

CAUTION

Select all cables and wire sizes in accordance with
applicable legislation.

CAUTION

After finishing the electrical work, confirm that each electric
part and terminal inside the electric part box is connected
securely.

DANGER

Never leave the unit unattended during installation or
servicing. When the service panel is removed live parts
can be easily touched by accident..

INFORMATION

Note that during the first running period of the unit,
required power input may be higher than stated on the
nameplate of the unit. This phenomenon originates from
the compressor that needs elapse of a 50 hours run in
period before reaching smooth operation and stable power
consumption.

on solid base.

Fall, vibration, noise

No refrigerant gas leaks.

Incomplete cooling/heating 
function
