Removing compressor (M2C)
*1
When replacing the
compressor (M2C), prepare
the accumulator heat insulator
(upper and lower) separately,
and attach it. Running the unit
without the accumulator heat
insulator, condensation may
occur, causing water to drip
outside the unit.
*2
Once the compressor
protection thermostat (S2T)
is removed, the radiation
sheet can no longer be used.
In that case, replace with
new one.
*3
After the compressor (M2C)
is replaced, the cumulative
compressor (M2C) running
time must be reset. Input
“ 0011 ” into the parameter
n035, and reset the cumulative
compressor running time. (refer
to page 67)
After input the parameter,
turning ON the power supply
again.
