3WAY VRF SYSTEM Unit Specifications
*1 It’s necessary to charge additional refrigerant of 70.5 oz (2.0 k
g
) per one outdoor unit.
*2 Width of product dimention in installation for multiple units is described by using Min unit clearance 60mm.
If installation hole pitch is 730mm or using snow-proof ducting, unit clearance should be 180mm.
*3 If the longest tubing equivalent length exceeds 295 ft. (90m), increase the sizes of the main tubes by 1 rank for suction tubes, discharge tubes
and liquid tubes.
With combination model, the specication of each outdoor unit is listed in [ ] , and connected by “+” .
