consists of:
1.1 Applications
HumiDisk
cold rooms and storage facilities for fresh produce, where lack of humidity leads to loss of weight and
product deterioration;
printing facilities, where the correct level of humidity must be maintained in order to avoid variations
in paper size;
textile industries, where humidity maintenance is an important factor in the productive processes, and
the need to eliminate the heat produced by the looms is essential.
These are just some of the industries which benefit from the application of the centrifugal-disk humidifier.

The fill valve operates according to an ON/OFF signal from a humidistat as well, and it is subj ected to the water level
command switch, while the heating element, subjected to the general switch, is always on.
It is possible to set the capacity of the atomized water (see 3.3 below and fig. 4).
Furthermore, it is possible to command two

3 Installation
3.1 Mounting
When you unpack the humidifier you will notice that it consists of two separate parts, different even from the electrical
point of view:
•
•
Before assembling the components decide in which direction you want to position the nozzles allowing the atomized
water to be spread in the environment. Finally fix the safety fixing brackets (see fig. 3).
3.1.1 Hanging mounting
To hang the appliance at the ceiling, connect it with chains or metal cables to the rings pr ovided (8), respecting the
minimum dimensions indicated in fig.1.
The minimum vertical distance from the ceiling must be 1000mm; the minimum horizontal distance from the wall
must be 114mm. Unit’s weight is 20Kg (fully loaded). The machine has to be installed in horizontal position.
Important: do not use hemp ropes or ropes made of any material that is sensitive to humidity.
3.1.2 Wall mounting
The minimum vertical distance from the ceiling must be 1000mm; the minimum horizontal distance from the wall
must be 114mm.
Use the special brackets (9) supplied with the appliance (fig.2). Fix the brackets (9) to the appliance using the screws
provided for the purpose.
Mark the holes on the wall where you want to install the appliance, respecting the distances between the holes on the
supporting brackets (9), so that, once it has been installed, the appliance is in horizontal position. The supporting
brackets are made in such a way that they keep the appliance at the right distance from the wall.

3.3 Setting humidifier capacity
In order to set the humidifying capacity follow these instructions:
•
unfasten the screws (B) under the fairing and slide the ring (A); the further the ring is pushed into the fairing (D), the
lower the humidifying capacity of the appliance is. The capacity ranges between 1.5 l/h (m in) and 5 l/h (m ax.);
•
fasten the ring in one of the three possible positions with the screws provided, matching the holes (C) in the ring (A)
with the holes (C') in the fairing.

4 Humidifier start-up
4.1 Start-up
Before starting the humidifier, make sure that:
1. the humidifier is installed in horizontal position;
2. all pipes are correctly installed and connected;
3. all the other components are properly assembled and installed in the correct position;
4. then power the unit;
5. use normal water only.
Important: always turn Off the main switch of the humidifier before moving the unit or carrying out any
intervention on it.
4.2 Main operations
1. Supply the humidifier with water;
2. turn ON the humidifier;
3. the atomized water will be conveyed through flexible p ipes and will be spread in the environment by the air flow
produced by the built-in fan;
4. during the humidification process, the water level in the tank will be kept constant by the float switch and solenoid
valve;
5. should the water level fall below the safety level, the float switch and the relay will immediately interrupt the
humidification process.
4.3 Warnings
1. Make sure the humidifier produces and spreads atomized water in a regular and uniform way; during
humidification the water valve must be kept OPEN;
2. never remove the upper part of the humidifier during normal operation;
3. do not stop up the air suction or supply pipe.

5 Maintenance
Check periodically the air filter (10) and, if necessary, remove and clean it (fig.3). To remove the filter (10), see 5.1
below. The filter may be washed with water or cleaned with a vacuum cleaner.
Warning: do not use the appliance without the filter (10).
If you have to remove the fan ( E) and the di sk (F) in fig. 4, firs t mark bo th the d isk and the fa n with a marking pen so
that you can reassemble them exactly in the same position. The fan-disk unit has been balanced in the given position.
IMPORTANT:
if you have to change the power supply cable, please ask for an original one.
5.1 Removing and reassembling the filter
To remove the filter, unscrew the fixing screws on the bars (ref. 12, fig.3).
To reassemble the filter, first block one o f the ends with the bar using the screws provided. Then take the other end
of the filter and the second bar at the same time and place them in fixing position. Hold down the bar so that it
clamps the filter against the appliance, then fasten the two remaining screws.
5.2 Storage
Keep the appliance in a place where the temperature ranges between -10°C and +60°C.
When the appliance is still in its package, keep the box in an upright position.
Do not pile other heavy material on top of the box.
5.3 What to do before and after long periods of inactivity
Before:
Turn off the general switch of the electrical panel and turn off the water supply tap.
Check the water tank. It must be empty.
Cover the machine to protect it from dust.
After:
The fan must turn freely without friction (to check this, lift the top part of the machine (fig.4) and push the red fan
(E) with your hand so that it turns).
The switch level of the float in the water tank must be able to go up and down.
The machine must be correctly installed.
5.4 Disposal of the product
The product is essentially made of plastic and metal, both recyclable. Before disposing of the product it is better to
separate the plastic parts (cover, fan, blades, etc.) from the metal ones (motor, tank, etc.).
