CAUTIONS Use the AirBench only for the designed duty – consult the manufacturer on any change of use. Each unit is marked with its design application, which is also shown on the commissioning certificate. The filters are not self-cleaning. They must be maintained / cleaned / replaced as described within.
Responsible Person reads this manual fully prior to installation and operation of the AirBench. This document refers to the AirBench FPW type. Models of this type are available with a range of filter configurations. The filter configuration in use is detailed on the system Commissioning Certificate and is used within this document to provide filter-specific maintenance information.
Unpack the unit and check for damage, if not already completed. The AirBench must be installed on a flat and level floor capable of carrying the weight of the unit. For nominal unit weights, see Specifications section at rear of manual. When determining an installation location, be aware that the air exhaust must discharge somewhere.

These items apply only when they have been ordered with the AirBench. ENCLOSURE Enclosures are supplied fully assembled where possible. Where shipping does not permit assembly prior to dispatch, enclosures should be assembled as follows using bolts supplied: Loosely fit left and right panels to left and right frame of bench.
COMMISSIONING General The initial commissioning and testing of your AirBench has been performed prior to delivery. However, as part of in-house commissioning we recommend that you complete the following tasks and record the results as appropriate in the system logbook.
Check the system logbook to ensure no routine maintenance is required. General use To use AirBench, ensure it is plugged in to a mains socket and the socket is switched on. Turn on the switch on the front of the bench.
The filters are not self-cleaning and must be maintained / cleaned / replaced as described below. Proper filter care is essential for the effective operation of your AirBench. If in doubt, contact the manufacturer for advice. When changing filters, the seals on which the filters sit should be checked for damage and replaced if necessary.

Labyrinth filters consist of a series of metal channels, in a metal frame. These filters can be emptied regularly using a vacuum cleaner by lifting the surface of the AirBench. They can also be removed and emptied. In general labyrinth filters do not require replacement except when damaged.
Filter Pressure Gauges A filter pressure gauge is fitted as standard to the front of each AirBench. This indicates performance of the unit as a whole, and filter condition. Certain models show a red zone on the filter gauge; when the gauge indicates within this zone, filters may be blocked or require cleaning.
THOROUGH EXAMINATION AND TESTING If AirBench is used as an LEV system it must be tested at regular (normally 12 month) intervals and certificated under the COSHH regulations. This service is available from us, or our approved testers. Thorough examination and test should include: Ensuring the prescribed maintenance routines are being completed and recorded within the system logbook.
