9 OPERATION RANGE
Power Supply
The applicable voltage range for each unit is given in “ the following table”. The working voltage among the three phases
must be balanced within 3% deviation from each voltage at the compressor terminals. The starting voltage must be higher
than 85% of the rated voltage.

Before shipment, this air conditioner is filled with the rated
amount of refrigerant subject to 10m piping length. (The
rated amount of refrigerant is indicated on the name plate.)
But when the piping length exceeds 10m, additional charge
is required according to the following table.

But when the piping length exceeds 10m, additional charge
is required according to the following table.
For other pipe length of other installation multiply
by the following correction factor to determine the
revised cooling capacity.

In case of 10 m long pipe (one-way), the
amount of refrigerant to be replenished is:
(10 - 10) x 20 = 0g
