REFRIGERANT PIPING

If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gas may be generated.
After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a fan heater, cooking stove or
heating unit, noxious gas may be generated.
Allowable length of refrigerant piping
The straight pipe section should be at least 0.2 m as shown in the figure below.
∗ Short length of the straight pipe section may cause abnormal sounds.
