Ho w to select the REF N ET joint
•
W hen u sing REF N ET joint at the first b ranch co u nted from the o u tdoor u nit side, choose from the follo w ing ta b le in
accordance w ith the capacity of the o u tdoor u nit.
For an o u tdoor u nit m u lti installation, make the settings in
accordance w ith the follo w ing fig u re.
Ho w to calc u late the additional refrigerant
to b e charged
If a negati v e res u lt is gotten for R from the form u la at right,
no refrigerant needs to b e added.
Additional refrigerant to b e charged R (l b .)
R sho u ld b e ro u nded off in u nits of 0.1(l b .).
