3. Before installation
3.1. Scope of this manual
This manual describes the procedures for handling,
installing and connecting 1U105~140 units.
3.2 Precautions
CAUTION
Since maximum working pressure is 4.3 MPa or
43.0 bar, pipes of larger wall thickness may be
required. Refer to paragraph "6.2. Selection of
piping material" on page 10.
NOTICE: Insulation resistance of the
compressor
If, after installation, refrigerant accumulates in the
compressor, the insulation resistance can drop, but if
it is at least 1 , then the machine will not break down.
Turn the power on and leave it on for six hours. Then,
check if the insulation resistance of the comressor
has risen or not.
The compressor will heat up and evaporate any
refrigerant in the compressor.
Check the following if the ground-fault circuit
interrupter is triggered:
Make sure that the interrupter is compatible with high
frequencies.
This unit has an inverter, so an interrupter capable
of handling high frequencies is needed to prevent
malfunction of the interrupter itself.
3.3. Precautions for R32
The refrigerant requires strict cautions for keeping the
system clean, dry and tight.
-Clean and dry
Foreign materials (including mineral oils or moisture)
should be prevented from getting mixed into the system.
-Tight
Read "9. Precautions on refrigerant piping" on page
10 carefully and follow these procedures correctly.
Since R32 is a mixed refrigerant, the required
additional refrigerant must be charged in its liquid
state.(If the refrigerant is in state of gas, its composition
changes and the system will not work properly).
The connected indoor units must be indoor units
designed exclusively for R32.
