Refrigerant Precautions
To reduce the risk of serious injury or death, the following refrigerant
precautions must be followed.

Ɣ If installed in a small room, take measures to prevent the refrigerant from exceeding the maximum
allowable concentration in the event that refrigerant gases should escape. Refrigerant gases can
cause asphyxiation (0.026 lbs/ft
3
(0.42 kg/m
3
) based on ISO 5149 for R410A). Consult with your
distributor for countermeasures (ventilation system and so on). If refrigerant gas has leaked during the
installation work, ventilate the room immediately.
Ɣ Check the design pressure for this product is 601 psi (4.15MPa). The pressure of the refrigerant
R410A is 1.4 times higher than that of the refrigerant R22. Therefore, the refrigerant piping for

refrigerant piping may rapture due to an excessive refrigerant pressure. Besides, pay attention to
the piping thickness when using copper refrigerant piping. The thickness of copper refrigerant piping
differs depending on its material.
Ɣ The refrigerant R410A is adopted. The refrigerant oil tends to be affected by foreign matters such
DVPRLVWXUHR[LGH¿OPRUIDW3HUIRUPWKHLQVWDOODWLRQZRUNZLWKFDUHWRSUHYHQWPRLVWXUHGXVWRU
different refrigerant from entering the refrigerant cycle. Foreign matter can be introduced into the cycle
from such parts as expansion valve and the operation may be unavailable.
Ɣ To avoid the possibility of different refrigerant or refrigerant oil being introduced into the cycle, the
sizes of the charging connections have been changed from R407C type and R22 type. It is necessary
to prepare the appropriate tools before performing installation work.
Ɣ Use refrigerant pipes and joints which are approved for use with R410A.
Ɣ A compressor/unit comprises a pressurized system. Never loosen threaded joints while the system is
under pressure and never open pressurized system parts.
Ɣ Before installation is complete, make sure that the refrigerant leak test has been performed. If

Ɣ When installing the unit, and connecting refrigerant piping, keep all piping runs as short as
possible, and make sure to securely connect the refrigerant piping before the compressor starts
operating. If the refrigerant piping is not connected and the compressor activates with the stop
valve opened, the refrigerant cycle will become subjected to extremely high pressure, which can

Ɣ When maintaining, relocating, and disposing of the unit, dismantle the refrigerant piping after the
compressor stops.
