Drainage Piping Work; Electrical Work - Mitsubishi Electric PUZ-HA24NHA1 Manuel D'installation

4. Installing the refrigerant piping
4.6. Addition of refrigerant
• Additional charging is not necessary if the pipe length does not exceed 30 m, 100 ft
• If the pipe length exceeds the specified length above, charge the unit with addi-
tional R410A refrigerant according to the permitted pipe lengths in the chart below.
* When the unit is stopped, charge the unit with the additional refrigerant through
the liquid stop valve after the pipe extensions and indoor unit have been vacu-
umized.
When the unit is operating, add refrigerant to the gas check valve using a
safety charger. Do not add liquid refrigerant directly to the check valve.

* After charging the unit with refrigerant, note the added refrigerant amount on
the service label (attached to the unit).
Refer to the "1.5. Using R410A refrigerant air conditioners" for more information.
• Be careful when installing multiple units. Connecting to an incorrect indoor unit
can lead to abnormally high pressure and have a serious effect on operation per-
formance.
