Installation
Connect a compressed air supply to the inlet of the T-piece (see picture no. 18
/ A).

Earth control measurement

Proper earth connection shall be checked after both main installation and
regular maintenance work. If a component, such as for example the top
module, is removed and refitted, earth connection must be verified.

Control measuring

A suitable measuring instrument must be used.
Earth connection is measured between GND1 and the following components
on FlexFilter EX (see picture no. 23):
1. High top ring
2. Low top ring
3. Pressure relief panel
4. High inlet ring
5. Low inlet ring
6. TVFD outlet
7. On the filter bags
8. Control filter
1.
NOTE! The duct systems (in- and outlet) must not be connected.
A) Disconnect the net earth from GND 1.
B) Measure between all components according to the list above (see
picture no. 23) and GND 1 (≤100 Ω).
C) Measure and check if contact between incoming duct system and the
free coupled incoming net earth ( ≤10^5 Ω).
2. Connect incoming duct system.
Make sure that there is a 2nd. earth connection between the duct system
and FlexFilter EX and that it is properly earthed to the FlexFilter EX.
A) Measure and check if contact between GND1 and external net earth (
≤10^5 Ω).
B) Reconnect net earth to GND1.
3. Connect outgoing duct system (make sure that there is an earth
connection between the duct system and FlexFilter EX).
