EKEQFCBAV3-US (EEV KITS)
INSTALLATION INSTRUCTIONS
Safety Considerations
Optional kit to use in combination with Daikin condensing units
with field 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 fluctuate depending on selected
air handler units and depending on the installation
configuration.
Connectivity to DIII-net devices only allowed with:
- Intelligent Touch Manager
