Optional kit to use in combination with Daikin condensing units
with eld supplied non VRV air handler units.
Field supplied air handler units can be connected with a Daikin
condensing unit via a control box and expansion valve kit. Each
circuit or coil requires a separate control box and expansion valve
kit. This manual describes the installation of the expansion valve
kit and the installation and operation of the EKEQMCBAV3-US
control box.
The below mentioned cautions should be considered prior to
installation
• Multi-module condensing units are permitted. However,
each refrigerant system cannot exceed the maximum
tonnage allowed by the applicable VRV heat pump system
type.
• The automatic refrigerant charging and leak detection
function are not possible when the EKEQMCBAV3-US is
used.
• The manufacturer of the outdoor unit has limited
responsibility for total performance of the system because
performance is determined by the total system. The
discharge air may uctuate depending on selected
air handler units and depending on the installation
conguration.
• Connectivity to DIII-net devices only allowed with:
- Intelligent Touch Manager
• This equipment is not designed for year-round cooling
applications with low indoor humidity conditions, such as
Electronic Data Processing rooms.
