							9 OPERATION RANGE
The applicable voltage range for each unit is given in “thefollowing table”. The workingvoltage 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.

							Correction of cooling and heating capacities according to
the connecting pipe length.
The data of cooling capacities (marked on the name plate)
are based on 7.5 metres connecting pipe and horizontal
installation.
(Cooling)
Equivalent Length = actual pipe length +
number of elbow x ELE + number of oil
trap x ELO
ELE: equiva lent length ofelbow.
ELO: equivalent length of oil trap.

The piping length exceeds 30 metres.
APPLICABLE FOR ALLMODELS
Before shipment, this air conditioner is filled with the rated
amoun t of refrigerant subject to 30m piping length. (The
rated amoun t of refrigerant is indicated on the name plate.)
But when the piping length exceed s 30m, additio nal 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 30 m long pipe (one-way), the
amoun t of refrigerant to be replenished is:
(30 - 30) x 20 = 0g

In case of 50m long pipe (one-way), the
amoun t of refrigerant to be replenished is:

Attention
 
    • 
• •  • 
Please never decrease the gas piping size. (It causes the breakdown of the compressor)
 
    • 
• •  • 
The equivalent piping length and the cooling and heating capacity change rate are same as the standard piping
specification.
