							7 OPERATING INSTRUCTION
7.1. Wired Remote Control (OPTIONAL PARTS)
NOTES:
 
    • 
• •  • 
Ensure that the correct button is pressed as simultaneous pressing of the multiple buttons will not make the setting correct.
 
    • 
• •  • 
The illustration above is for explan atory purposes only. The appearance will be different during actual operation.
 
    • 
• •  • 
Do not operate the remote control with wet hands. Otherwise, electric shock or malfun ction may occur.
 
    • 
• •  • 
Do not press the remote control buttons with sharp object as this may damage the remote control.
 
    • 
• •  • 
Buttons marked with * are not needed for normal operation. If one of these buttons is pressed by mistake, press the same
button once more to cancel the operation.
 
    • 
• •  • 
W hen the power resumed after power failure, the unit will restart automatically with all the previous settings preserved by the
memory function. (Auto restart function)

Power Supply
The applica ble voltage range for each unit is given in the following table. The working voltage among the three phases must be
balanc ed within a 3% deviation from each voltage at the compressor terminals. The starting voltage must be higher than 85% of
the rated voltage.

CORRECTION OF COOLINGCAPACITY ANDHEATINGCAPACITIES
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 meters connecting pipe and horizon tal installa tion.
For other pipe length of other installa tion multiply by the following correction factor to determine the revised cooling capacity.

REFRIGERANT ADDITIONAL CHARGE
 1. Piping installation by standard piping
 
    • 
• •  • 
At the time of shipment from the factory, this unit is charged with enough refrigerant for an equivalent pipe length of 30m.
(Refer to the following table)
But when the piping length exceed s 30m, additio nal charge is required according to the following table.
Example:
CU-V50BB P8
In case of 50m long pipe (one way), the amoun t of refrigerant to be replenished is: (50 - 30) x 50 = 1,000g

 2. Piping installation by existing piping
The above models change the liquid pipe size of the previous series. It is to use the existing piping by adjusting the refrigerant
gas volume.
Please do correct piping installa tion referring to the above table.
 
    • 
• •  • 
Please do not 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.
