1. Determine the weight of refrigerant to be charged additionally.
Piping length is the one way length of gas or liquid piping whichever is the longest.
It is not necessary to charge additionally if the piping length is under 10 m.
If the piping length is over 10 m please determine the additional amount of refrigerant to be charged
using the table below.
Table:
Additional charging of refrigerant <unit: kg>
(a) Additional charge not required
Complete recharging
In case complete recharging is required (after a leak, etc.), refer to the table below to determine the
necessary amount of refrigerant.
Before recharging, make sure to execute vacuum drying of the internal piping of the unit as well. To
do so, use the internal service port of the unit. Do NOT use the service ports located on the stop valve,
since vacuum drying can not be performed properly from these ports.
Outdoor units have 1 port on the piping. It is between the heat exchanger and the 4-way valve.
Table:
Total charging amount <unit: kg>
2. After the vacuum drying is finished, open valve A (5) and charge the additional refrigerant in its
liquid state through the service port on the liquid stop valve taking into account following
instructions:
- Turn on the power of the outdoor unit and indoor units.
- Check that gas and liquid stop valves are closed.
- Stop the compressor and charge the specified weight of refrigerant.
To avoid compressor breakdown. Do not charge the refrigerant more than the specified amount.
Procedure: Charging while the outdoor unit is at a standstill
