In general, the optimal frequency can range from once every 15 days to once every 2 months. It is advisable to start with frequent
checks, and then adjust the frequency based on the level of fouling detected.
Follow the procedure below:
1. open the access panel;
2. take the filters out with care to avoid spreading dirt in the area below;
3. wash the filter mat in lukewarm water with a common detergent;
4. rinse thoroughly in running water avoiding dispersal in the environment;
5. dry the filter;
6. put it back in its place;
7. reassemble the closing panels.
Old filters, wastewater and residues must be disposed of according to the regulations in force.
Steam humidifier
Regular checks.
• After one hour of operation
In the case of both disposable cylinders and openable cylinders, check for any significant water leaks.
• Every 15 days and after no more than the first 300 operating hours
In the case of both disposable cylinders and openable cylinders, check operation and for any significant water leaks, and assess the
general condition of the container. Check that arcs or sparks are not generated between the electrodes during operation.
• Quarterly and after no more than 1000 operating hours
In the case of disposable cylinders, check operation and for any significant water leaks, and replace the cylinder if necessary. In the
case of cylinders that can be opened, check for any significantly blackened areas on the container. If so, check the electrodes for
fouling and replace them as necessary, together with the sealing O-rings and the cover gasket.
• Annually and after no more than 2500 operating hours
Replace any disposable cylinders. Check the operation of cylinders that can be opened, if there are significant air leaks, the general
condition of the container, any noticeable blackened areas of the container. Replace the electrodes, together with the sealing O-
rings and the cover gasket.
• After five years and after no more than 10,000 operating hours
In the case of both disposable cylinders and openable cylinders, replace the entire cylinder.
Refer to the manual of the steam humidifier supplied with the unit for further information.
Electric heaters (optional component)
Check:
•
The level of cleanliness.
•
Correct fastening.
•
For any signs of corrosion.
Rotary exchanger
•
Rotor maintenance.
The space around the heat exchanger affects operation, efficiency and pressure drop. The main parts of the heat exchanger should
be checked regularly, especially when air quality is poor. This simply involves carrying out periodical visual inspections.
The rotor must be checked regularly to prevent build up of dust and dirt. Even if the air handling unit is installed with filters, these
may break, allowing dirt to enter and block the rotor.
If dust and dirt build up on the rotor, these can easily be removed as follows:
Vacuum cleaner, for small amounts of dry dirt.
-
-
Compressed air, in case of significant dry deposits. Make sure not to damage the rotor.
Pressure washer with hot water (max 70°C) or detergent spray (e.g.Decade, ND-150, Chem Zyme, Primasept, Poly-Det,
-
Oakite 86M or the like) to remove grease or significant amounts of damp dirt.
Avoid using strongly alkaline or other corrosive substances to clean the rotor.
