Filtering unit
HARD-1000-S
5 z 8
Implemented functions of the control unit:
●
Q1M
– motor protective switch – protects the motor from failure due to the blocked start-up, overload and
short-circuit;
●
P1
– hour-meter – to count the work hours of the device;
●
F1
– over-current protection – to safeguard the control circuit;
●
K1M
– contactor – start-up of the fan;
●
B1
– pressure control (pressostat) – compares the pressure in front of the filter and behind the filter;
when the difference reaches 500 Pa the contact closes;
●
B2
– pressure control (pressostat) – compares the pressure in front of the filter and behind the filter;
when the difference reaches 500 Pa the contact closes;
●
S1.H1
– white lamp – indicates the applied voltage onto the control circuit;
●
S2.H2
– green lamp – indicates work of the device – status “
RUN
”;
●
H3
– modular yellow lamp – indicates pollution state of the filter;
●
H4
– modular yellow lamp – indicates pollution state of the filter;
●
S2.1
– fan work –
STOP
;
●
S2.2
– fan work –
START
.
OPERATIONAL USE
During the use, observe the replacement periods of filters by monitoring the signal lamps activated by the pres-
sure controls (pressostats). The lighting signal lamps indicate the replacement necessity of the following filters:
–
H3
yellow lamp
– signalizes the replacement necessity of the
pocket filter
– upon limit resistance of the filter
– 500 Pa; the lamp is coordinated with
B1
pressure control (pressostat);
–
H4
yellow lamp
– indicates replacement obligation of the
high-efficiency filter
– filter limit resistance 500 Pa
the lamp is coordinated with
B2
pressure control (pressostat).
Replacement of the pocket filter
– beforehand, release the filter clamps and gently slide the filter out of the guide
profiles. In order to replace the high-efficiency filter, first pull out the pocket filter, then (gripping the front handle
and rear handle of the high-efficiency filter) lift and remove it from the HARD-1000-S filtering unit.
Do not slide the high-efficiency filter directly on the guide profiles (while pulling out), as this could damage the
sealing and cause filter malfunction as a result afterwards. The same rule applies while inserting and removing
the filter
Replace the nonwoven (spunbond) paint-stop filter, after you observe the fan efficiency decrease. User should on
one’s own estimate the filter replacement time, depending on the specified technological process. Activated
carbon filter ought to be replaced when it stops absorbing the unpleasant smells/odours. Observe the indications
of the hour-meter (measuring the work time). The activated carbon layer should be replaced after approx. 200
hours of operation. Nevertheless, this depends on the intensity of contaminates accumulation.
