SPECIFICATION

GENERAL SERVICING & MAINTENANCE INFORMATION

General The frequency of maintenance required will vary according to the usage of the

unit (measured in hours, see Sevice Meter) and the types of solvents used. This

can vary accordingly between periods of three to twelve months.

Filters To ensure that the vacuum/suction filtration unit always performs at peak

performance it is essential to replace the main carbon filter before twelve months

and sooner if non-water based solvents are used.

Vacuum Motors The special acoustic vacuum motors, 2 off, are fitted with auto-stop carbon

brushes, to protect the motors. The brush is designed to disengage the contact

between the carbon brush and the commutator. It is recommended that the

carbon brushes are inspected and/or replaced after a period of between

1000-1500 hours, see Service Meter. This will save any down-time should the

carbon brush autostop.

Service Meter A service meter is fitted to the front control panel showing the machine useage in

hours. The meter is provided as a reference as part of a routine maintenance

programme.

Hoses Clear flexible spiral interlocked E.V.A. hose. Crush resistant and durable,

requiring only visual inspection.

Cabinets The tough high-impact ABS cabinet requires little or no maintenance, other than

ensuring that the fixtures at the rear of the lid are always in place and that the unit

is situated on level ground.
