Check the flow of water to the
exchangers (where fitted)
Measure the temperature of the input
and output water of the exchangers
(where fitted)
Check oil level
Check the acidity, humidity, pressure
and temperature of the oil sump
Check the filter and clean the oil
Replace oil
check correct operation of compressor
oil case resistance
* The frequency of the operations described in the table above should be considered indicative. In fact, it may undergo variations
according to the method of use of the unit and the system in which the latter is required to operate.
Just think of the frequency of filter replacement. Fouling is obviously affected by the quality of the treated air.
Structure
Check the condition of the structure of the unit.
Treat with paints designed to eliminate or reduce oxidation those points of the unit where the problem can occur.
Check the fastening of the external panelling of the unit. Loose fasteners may cause abnormal noise and vibration.
Internal air coil and drip tray
Accidental contact with the fins of the heat exchanger can cause physical injury. Take all the necessary precautions and wear suitable
protective gloves.
The finned surfaces of the cooling coils and the drip trays in particular are places where microorganisms and mould can proliferate.
Clean with suitable cleaning products on a regular basis and perform disinfection with sanitising products if necessary.
Accumulated dirt can cause clogging that prevents the correct flow of the condensate.
Filters
In the interest of ensuring the high performance and energy efficiency of the air handling unit, there must be a differential pressure
switch for each filtering section of the control system of the WIZARDX units that can trigger an alarm when the drop in pressure at
the filter exceeds the maximum permitted value. This alarm appears on the user interface terminal.
EPM1 50% - ISO 16890 (F7 - EN 779:2012) rigid bag filters (standard), activated carbon rigid bag filters or EPM1 85% - ISO
16890 (F9 - EN 779:2012) rigid bag filters (both available as optional accessories)
Pocket filters cannot be refurbished. Once dirty, they must always be replaced.
1. open the access panel;
2. take the filters out with care to avoid spreading dirt in the area below;
3. insert the new filters, fitting them in the same direction as those that were just removed;
4. close the panel;
5. send the old filters to a specialised collection or recycling centre (comply with the regulations in force).
ISO COARSE 55% - ISO 16890 (G4 - EN 779:2012) synthetic pleated air filters
It is essential that the air handling coil is able to offer maximum heat transfer. The unit must therefore always be operated with the
air filters installed and the filters must be kept in proper condition.
Cleaning and replacing the filters when necessary is essential not only for practical reasons but are also very important from the
point of view of health and hygiene.
Clogged filters can reduce the air flow rate and, therefore, cause malfunctions and blockages as well as breaking of the unit and
downtime.
The frequency at which to check the filters depends on the quality of the supply of air from outside, the hours of operation of the unit,
the level of dust and the number of people in the rooms.
