Field Piping
This unit requires additional charging of refrigerant according to the length of pipe connected at the site.
When the entire refrigerant pipe length is within 30 meters, the additional changing is not needed.
Take the following steps for proper charging.
(1) Additional charging of refrigerant
Select the appropriate refrigerant charging amout from Table 2, 3 and charge the refrigerant. Fill out the
notice plate attached in the rear of the front plate (2) for future servicing.
• Pair-type

(unit: kg)
Simultaneous operation multi-type
• Find the entire pipe length by totaling that of each pipe in the order of the main pipe (L1), and branched
pipes (L2), (L3) calculate the excess length going over 30 meters, then select from Table 3 the amount of
refrigerant corresponding to the excess length.
The total value is the amount required for additional charging.
Table 2 Additional charging amount
(unit: kg)
(2) Complete charging of the refrigerant
When the entire refrigerant pipe length is within 30 meters, charge the refrigerant in accordance with the
amount mentioned in the nameplate, and when the pipe length exceeds 30 meters, the charging amount
mentioned in the nameplate and that required for additional charging are to be totaled as the net charging
amount.
*Vacuum drying when refilling the refrigerant will not be sufficient if done only at the shut-off valve service
port (gas and liquid sides), so it should be done from a service port set up on the pipe leading from the out-
door unit 4-path switch valve to the heat exchanger.
