NTRODUCTION
The Daikin ER-DA air-cooled condensing units are designed for
outdoor installation and used for cooling applications only. The units
are available in 4 standard sizes with nominal cooling capacities
ranging from 8.3 to 26.6 kW.
The ER-DA condensing units can be combined with the Daikin EFD-F*
and EFV-JB split air-cooled air conditioners or any other type of air
conditioner equipped with a thermostatic expansion valve.
The present installation manual describes the procedures for
unpacking, installing and connecting the ER-DA units. Installation of
the EFD-F* or EFV-JB units is not described in this manual. Always
refer to the installation manual supplied with these units for their
installation.
