the valve should be replaced if any signs of over-
load or leakage is detected. The sensor needs to
be replaced after each explosion.
• The brush shoe has been designed to last at least
one year of continious operation, and should be
replaced annually. In case any substantial wear is
detected within a shorter period, the brush shoe
should be replaced anyway, and the reason for the
wear examined.
• The ground straps connecting all major parts of the
separator, should always be securely installed dur-
ing operation. The grounding points are indicated
by an earth symbol sticker as shown below. Annu-
ally check for damaged or loose connections, and
measure the resistance between the top of both M8
threads. The resistance in each connection must
not exceed 10 Ohm acc. to EN 60079. If the value
6
is exceeded, check for falty connections.
Lubrication of the gear:
The gear is provided with mineral oil, ISO VG 220, for
operation in a region of ÷10 - 40°C. At working temper-
atures outside this area, synthetic oil should be used.
Recommended synthetic oil types are:
