Air-to-water Heat Pump
Note
when vacuuming is finished, pressure inside the unit should be kept lower than 80Pa for at least 30 minutes to
make sure there is no leak. Either charging valve 1 or charging valve 2 can be used for vacuuming.
Charging
: when vacuuming is finished and it is certain that there is no leak, charging can be done.
(1) Be sure to charge the specified amount of refrigerant in liquid state.
(2) Since this refrigerant is a mixed refrigerant, adding it in gas form may cause the refrigerant composition to
change, preventing normal operation.
(3) Before charging, check whether the refrigerant cylinder is equipped with a siphon tube or not.
