• Press SELECT MENU: code 7H (RUNNING HOURS) will
flash on the display. Immediately after it appears the
letter H and the 2 first numbers (from 0 to 65) of the 5
which indicate the running hours. Running hours 12 370,
shows H12.
• Press SELECT MENU: figure 8 PAS will flash on the
display, key access to the SUBMENU (to be used only if
necessary).
• Press SELECT MENU: the letter E will appear on the
display, the cleaning CYCLE starts.
Note:
- When pressing the key DELTA-P/VALVES you can return in
E position from every step of the programming MENU.
- During programming, after 2 minutes from the last setting,
the unit will automatically go to E position.
- The system will automatically ignore the outlets which
have not been connected.
- During the first cycle, check that all of the outlets function
are correct (in the case that they are ignored check the
connections to the valves).
Start up
Adjustment damper:
• Check that the damper for adjusting the airflow is fitted
to the filter's outlet side.
As the pressure drop across the filter cartridges is low during
the breaking-in period, the airflow will exceed the estimated
operating flow. This can mean that the life-span of the
cartridges is shortened drastically. Therefore the following
adjustment must be made before the filtration is started up.
• Adjust the damper to about 40-50% open.
• Start up the fan.
• Adjust the airflow using a flow-meter to the correct flow
for the application.
• Read off the pressure drop on the manometer (B) or on
digital display (control cabinet C type) and make a note
of it.
• Open the damper gradually during the breaking-in period
(about 2-4 weeks) until the manometer or digital displays
an operating pressure of 700-1.000 Pa (2,8-4"). The time
it takes to achieve normal operating pressure can vary
depending on the dust concentration and the type of
application.
• During the breaking-in period, readings of the
manometer (B) or digital display has to be done
continuously. Make a note of all values as these form the
basis for checking the status of the filter cartridges.
• In certain applications, (e.g. plasma and laser cutting),
the filter cartridges must be precoated with synthetic
particles in order to obtain maximum filter functionality.
If precoating of the filter cartridges is directed, contact
the Plymovent technical department.
precoating
Precoating is a recommendation in all applications, especially
in applications with plasma and laser cutting.
Precoating will be undertaken with Neutralite pigment and
dosed with 0,5-1,0 kg pigment for one filter cartridges.
- Dosage shall be done in a time of minimum of 30 sec. per
filter cartridges (0,5-1,0 kg).
- Dosage shall be earned out in a even flow.
- Neutralite pigment shall be dosaged in the nearest
extracting point to the filter.
- The fan shall work with full capacity.
- The filter cleaning system shall be shut off.
- No process gas (dust) may pass the filter system during
the precoating process.
NOTE! Use protection gloves.

THE FOLLOWING POINTS ARE TO BE CHECKED AND
IMPLEMENTED BEFORE THE FILTER unit IS PUT INTO
OPERATION:
ELECTRICITY: see electrical diagrams.
• Check that the correct electrical supply voltage is
connected to the filter's control cabinet.
• Is the MAIN SWITCH in the "ON" position.
• Check that the correct configuration for the controller
card is done (see adjustments for controller card).
• Check that the magnetic valves are correctly connected.
See electrical diagram.
When the main switch is turned on, and the configuration
on the door panel membrane is done (see previous
section), the system starts cleaning and an indication
LED indicates the activated output. The system ignores
outputs that are not connected in order to avoid
unnecessary pauses.
During the first cleaning cycle, it is IMPORTANT to check the
automatic search so that no connected outputs are ignored.
Manometer:
• Check that the manometer is fitted and connected at the
side panel of the filter module, Note: only in combination
with -A and -B control cabinets.
