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 R410A 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 R410A.

3. Before installation

3.2. Precautions

This manual describes the procedures for handling,
installing and connecting 1UH071~250 units.

CAUTION

NOTICE: Insulation resistance of the compressor

Since maximum working pressure is 4.15 MPa or 41.5
bar, pipes of larger wall thickness may be required. Refer

to paragraph "6.2. Selection of piping material" on page

10.

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.
