2.6 Electrical connections

Installation requires the use of an ON/OFF humidistat that controls the operation of the humidifi er: in
place of this, however, a simple ON/OFF contact can be used, with the only difference that the appliance
must be started and stopped manually. This choice however does not in any way infl uence the installation
procedure described below.
Important: A device must be installed for isolating the appliance from the power supply, as shown in Fig.
Fig. 2.r and 2.s. A 2.5 A slow blow fuse must also be installed for staring the motor.
