9 - COMMISSIONING

9.1 - Siphon

■ The siphon must be activated during commissioning, or after each period of prolonged downtime. To do this, fill the drain pan with
water and check that it drains quickly with no stagnant areas.
■ The siphon level must be checked periodically. Operation without condensation may result in evaporation of the water contained
in the siphons.

9.2 - Pre-commissioning check

Commissioning must be performed by qualified personnel in accordance with the safety rules and standards.
■ Check the following points:
Remove:
- Any protective films.
- All shipping safety devices.
Check:
- All of the casings (structure, profiles, doors, gaskets, handles, panels).
- That the unit and its components meet the order specifications.
- That all of the documents and safety equipment required by the applicable European standards are present.
- The network voltage: It must match the unit voltage and its value must remain within the permissible limits (+10 % to -10 % of
the nominal voltage).
- The calibration of the heat protection in relation to the current of the various components.
- The tightness of the connections.
- The internal cleanliness of the unit: remove any foreign objects from inside it (paper, packaging, dust, etc.).
Make sure all electric components are grounded.
During lifting operations, the tunnel sealing gaskets are subjected to mechanical stress. They must be checked.
Also ensure that the ventilated room is clean before starting up the extraction.

9.3 - Filters

Warning!
Follow the safety instructions (see § 2 - SAFETY INSTRUCTIONS).
The filter cells are flammable products, and the fire risk may increase depending on the elements filtered by the medium. Keep the
filters away from flames.
Mounting, cleaning and replacement of filters pose risks of allergies and irritation of the skin, airways and eyes. When working on the
filters, always use suitable Personal Protective Equipment (gloves, mask, safety glasses, etc.).
■ Commissioning phases:
1. Check the condition of the filters and the sealing gaskets (except for assembly with bare runners).
2. Check for mechanical jamming of the filters.
3. Clean the components upstream of the filters and the duct networks.
4. Clean the filter support frames.
5. For a VDI 6022 installation, check that the pressure gauge is present.
6. Clean the inside of the filtration box. Remove any impurities using a vacuum cleaner and/or a cleaning product.
7. Make sure there are no foreign objects inside the box.
8. It is strongly recommended, if regulations permit, to operate your system for a few hours with prefilters only. In fact, large quantities
of dust and other compounds can quickly clog the filters - in particular high efficiency filters - and affect the operation and performance
of the unit.
9. Repeat the operation several times if necessary.
10. All of the final filter stages can then be installed.
11. Check the pressure drop on each filter stage.

For further clarification, please refer to the internal release specifying the pressure drop data based on the filter fouling level (clean,
semi-fouled, fouled).
The manufacturer cannot be held liable if the filter is replaced using a brand or model that differs from the original filter brand or model
(EN 846 certified for hygiene versions).
