5.3 Mechanical Specifications
The cabinet and legs are made of aluminum. In the multi-fan
models the air ow is maintained separated. The protection
mask of copper pipe is used to protect the inlet and outlet
copper pipes.
The window is used to clear the heat exchanger periodically.
The attaching legs are the same for horizontal and vertical
installation.
Fan
The axial fan motor is built with external rotor.
The position and appearance of the fan are shown in the gures
of this page.
Temperature sensor
One is installed at the outlet of the condenser inside the
protection mask of copper pipe. The other is installed on the
end plate under the electrical control box. They are used to
collect the outlet temperature of the condenser and ambient
temperature respectively.
5.4 E󰀩ciency Control System
EC fans The EC fan is an integral assembly of an electronically commutated motor, quiet fan blade assembly and
nger/hail guard.
Control by
Indoor Unit/EC
Fan
The condenser is directly connected to the indoor unit via Modbus communication. The unit is able to optimize
the system by managing everything through a single control, then combines the advantages of EC fans with
system management. The system allows to adjust the system pressure (head pressure setpoint). The pressure
transducer is present and wired inside the indoor unit.
