The operation of the humiDisk
• Control the humidifi cation capacity
• Start and control the washing/reset cycle.

4.2 Dip-switch

In the board (Fig. 4.a) capacity regulation is made by combining the position of the dip-switches accor-
ding to the table to the side.

4.3 Adjusting the humidifi cation capacity
Tab. 4.a
The capacity can be adjusted during the installation phase, or later, for example, to adapt the operation of
the appliance to variations in the conditions in the environment where it has been installed. In this case,
proceed as follows:
• complete the stopping procedure as shown in par. 3.3;
• remove the air fi lter by unscrewing the three fastening screws;
• remove the junction box by releasing the spring;
• open the junction box and adjust the position of the potentiometer as desired;
• close the appliance as described in par. 2.8 "Final operations".
Start the humidifi er again.

4.4 Washing/emptying cycle

The electronic board on the humiDisk
• the appliance is started using the main switch;
• the humidistat switches the appliance off because the desired RH conditions have been reached.
The purpose of this cycle is to prevent water depositing in the appliance when it is not in operation, in this
way preventing the proliferation of bacteria.
The cycle has a fi xed duration, and involves:
• Stopping the motor, with a 40 second waiting period: this waiting period gives the motor (and thus the
fan/disk unit) time to stop completely, and allows the water in the appliance to collect at the bottom of
the tank.
• Activation of the water fi ll solenoid valve: the water enters the tank until tripping the level sensor.
• Maintaining the water fi ll solenoid valve enabled for 10 seconds after the level sensor has tripped: in this
way the water level in the tank exceeds the normal level of operation and the drain siphon is primed,
thus draining the water in the tank.
• Deactivation of the fi ll solenoid valve;
• Waiting for a fi xed time of 10 seconds: this time period is needed to make sure that all the water in the
tank is drained.
• End of the washing/emptying cycle: at the end of the washing/emptying cycle the appliance waits for the
humidistat contact to be closed or, if it is already closed, starts the motor and starts humidifying again.

4.5 Washing/emptying cycle using CAREL electrical panels

Note: when using the CAREL electrical panels, the washing cycle can be extended when the humidifi er, in
On status, is activated by the humidity probe for a new production cycle (see chapter 9 in the manual).
