This document provides installation and operation manuals for Daikin Ceiling Concealed Split Type Air Conditioners, specifically models FDKR200AV16, FDKR300AV16, and FDKR400AV16.

Function Description:

The Daikin Ceiling Concealed Split Type Air Conditioner is designed to provide cooling for various environments, including shops, light industry, farms, and commercial use. It operates as a split system, meaning it consists of an indoor unit (fan-coil) and an outdoor unit (condensing unit) connected by refrigerant piping. The system uses R410A refrigerant, which is a mixed refrigerant that does not contain chlorine, does not destroy the ozone layer, and contributes only slightly to the greenhouse effect if released. The unit is designed for concealed installation within the ceiling, offering a discreet aesthetic while providing efficient air conditioning.
