7.3 Cleaning and Maintenance Tasks
Clean or replace the Mesh Filters and Collector Cell and clean the Main Chassis at the
prescribed intervals mentioned in Maintenance and Cleaning Schedule on page 26 or:
● If the Mesh Filters and/or Collector Cell are damaged.
● When the Collector Cell starts to make a crackling sound (arcing).
● When the filtering and extraction performance of the Unit starts to decline.
It is a matter of experience to determine when the Unit needs to be cleaned, since the
nature and the degree of pollution depends strongly on factors such as the particular
location, humidity, and intensity of use etc. Nevertheless, the filters and Main Chassis
should be cleaned regularly at intervals ranging from once a week to once every 3 months
using the procedures outlined in the sections below:
7.3.1 Removing the Mesh Filters and Collector Cell
Start the cleaning procedure by removing the Mesh Filters and Collector Cell from the
Main Chassis:
1.
Isolate the Unit from the mains power supply by turning the Rotary Mains Isolator
Switch to the ‘Off’ position.
2. Allow at least 60 seconds for any static electrical charge to dissipate.
3. Double check that the mains power supply has been isolated.
4. Unscrew the top and bottom Star Knobs on the main Door Assembly anti-clockwise
and open it.
5. Remove the Mesh Pre-Filter, Collector Cell and the Mesh Post-Filter in this order.
6. Remove the Filter Carrier.
7.3.2 Cleaning the Main Chassis
Having removed the Mesh Filters (pre and post) and the Collector Cell:
1.
Remove any accumulated grease from the sump; depending on its viscosity, either
via the Drain Plug (see Figure 5 - Electrostatic Precipitator Unit - Main Chassis
Components on page 10) or by scooping and scraping it out.
2. Spray the sump with a high quality degreaser and wipe over the sump’s surfaces
with a suitable cloth or paper towels.
3. Clean the electrical contact points on the inside of the Door Assembly, using a high
quality degreaser and a suitable cloth or paper towels, ensuring that they are free of
contaminants/grease.
4. Ensure that the rubber door seal is undamaged and free from contaminants/grease,
cleaning with warm soapy water if necessary.
5. Clean the Filter Carrier and Backplate, using a high quality degreaser and a cloth,
and replace in the Unit.
