Regular maintenance and inspections should be performed on the HiVol and
associated equipment. Damage to the HiVol and electrical cord may jeopardise safety
and cause potential fire hazards. Periodic statutory electrical safety checks are also
required in most countries.
The HiVol sampler will normally spend its entire lifetime in the field exposed to the
weather.
It is therefore important that the equipment is regularly inspected and maintained as
this will assist in obtaining high quality data and reliable performance.
The frequency of cleaning and maintenance will depend on the site location and the
sampling sequence selected for monitoring.
It is recommended that a plan is developed for regular maintenance and that any
maintenance is recorded in the instrument log-book for the HiVol sampler.
A typical maintenance procedure for the Ecotech HiVol 3000 is contained in Table 1.
Note: The high volume sampler motor is
equipped with sealed groove ball bearings,
which do not need lubrication. The grease
filling is sufficient for the whole service life of
the bearings.
