6-7. Replenishing refrigerant
In order to assure the reliability of the appliance, the amount of refrigerant to be replenished shall be subject to
the following restrictions. Follow the margin of excess replenished refrigerant, which is equivalent to the current
R22. Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which may result in
failure, explosion of the product, or personal injury.
[Possible gas leakage]
Recharging refrigerant is allowed only if it is confirmed that the amount of leakage (e.g. slow leakage upon
installation) is within the additional margin specified below.
The amount of leakage is not certain if the product does not function properly (e.g. insufficient cooling / heating
performance). In such case, recover the refrigerant and replenish the refrigerant.
[Restrictions for the amount of additional charging]
a. The amount of refrigerant additionally charged shall not exceed 10% of that specified. If the situation is not
solved with such amount, recover the refrigerant completely and charge the specified amount.
b. In case of slow leakage upon installation and the pipe connection length of not over 15m, further tighten the
flare nut or take other effective measures. Do not recharge the refrigerant.
[Cautions for recharging with refrigerant]
a. Use a scale with an accuracy of at least 10g to recharge the refrigerant. Do not use a bathroom scale.
b. If the refrigerant leaks, identify the source and make sure to repair it. The refrigerant gas is not hazardous,
but if it touches a heat source (e.g. fan heater, stove), a poisonous gas may be generated.
c. Use liquid refrigerant for replenishment. Replenish the refrigerant carefully and slowly.
