Main features

6-6

Simple and rapid installation

6-6-9

Downsizing refrigerant piping

Reduced piping diameters

Use of high efficiency R-410A enables the VRV II to operate on a smaller refrigerant charge to be used, leading to a reduction in liquid and gas pipe 
diameters.

Reduced piping costs thanks to modular design

Smaller diameter liquid and gas piping contributes to a reduction in installation space and installation costs.

6-6-10

Sequential start

Up to 3 outdoor units can be connected to 1 power supply and can be turned on sequentially. This allows the number of breakers and their capacities 
to remain small and simplifies wiring (for models of 10Hp or less).

6-6-11

Self diagnosis

Detects malfunctions in major locations of the system and displays the type of malfunction and location, which in turn allows servicing and maintenance 
to be performed more efficiently.
