4. Refrigerant filling
Refrigerant filling must be done in the state of liquid refrigerant. If this is done in gas refrigerant, the balance of refrigerant
composition will collapse and damage the operation.
For the use of a gas cylinder without siphon inside, turn it upside down and use it.
(We recommend manifold with sight glass.)
Do not use a "CHARGE CYLINDER".
Caution
As a rule, please collect all existing refrigerants in the system outside the system when the refrigerant leakage occurs by the
Caution
system.
After that, please fill new refrigerant of a regulated amount again.
DRY VACUUMING
• If vacuum pump possible vacuuming until less than -100.7kPa.
1. Running vacuum pump at both liquid and gas side for more than 1 hour and vacuuming until -100.7kPa.
2. After that keep the pressure -100.7kPa for 1 hour and confirm the vacuum gauge value not increasing.
3. If vacuum gauge value is increase, there is possibility of water inside the unit or there is any leakage.
