2.- INSTALLATION
CHARGE OF REFRIGERANT FOR THE SET:
EXAMPLE:
To install a KVHK 38E + LEHK 38E set, with a 22m refrigerant line length between outdoor and indoor unit, then
the refrigerant charge must be calculated as follow:
1º Type of refrigerant R-22 or R-407C, in this case, R-407C .
2º The TABLE 4 shows, that for 22m of line length between indoor unit and outdoor unit, the line sizes are, liquid
7/8", and gas 1-5/8".
3º TABLE 4 shows, for line sizes of 7/8"- 1-5/8", the charge per meter line is: 327 gr/m.
4º TABLE 2 shows, charge of refrigerant for the set with 0m of line length is 10.500gr.
5º To determine the charge of the set:
Add charge of the refrigerant lines + charge of refrigerant indoor unit and outdoor unit.
Total charge for the set: (327 gr/m) x 22m + 10.500 gr = 17.694 gr
