NOTE
：
(1) Check the gas pipe and liquid pipe are equivalent in terms of the piping length and piping system.
(2) Piping length between outdoor units should be La≤Lb≤Lc≤32.8ft.(10m).
(3) If the piping length between branch and indoor unit (L3) is considerably longer than others, refrigerant may not ow well
and also performance may be deteriorated compared to other models. (Recommended: L3≤49.2ft.(15m))
(4) When the liquid piping length is longer than 49.2ft. (15m), use Φ3/8in. (9.53mm) pipe and reducer (eld-supplied).
(5) Allowable total piping length may become shorter than 3280.8ft.(1,000m) due to the limitation of maximum additional
refrigerant amount.
(6) Function setting of Ci is required (Ci=2), in case of height di󰀨erence between indoor units: 49.2ft.(15m)
<
H2 ≤98.4ft.(30m).
(7) In case of the height di󰀨erence between outdoor units and indoor units: 164ft.(131.2ft.) < H1 ≤295.3ft., contact technical
department of the manufacture.
