15. TEST 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.

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.
