Routine maintenance
To help keep your unit in good working order and to make sure it gives you optimum
performance, we recommend that you carry out the following:
Monthly
• Clean the unit, as detailed in “Cleaning” below.
• Check all controls, such as pushbuttons, for freedom of operation.
• Check the functionality of all controls and indicators, such as LEDs.
• Check the functionality of the equipment.
Yearly
• Clean the internal fans, see “Cleaning the internal fans” below.
Cleaning
Switch off the unit and electrically isolate it from the mains before cleaning.
Clean the unit using a dry, lint-free cloth. Don’t use harsh abrasives or solvents. When
cleaning the unit, take great care not to damage the controls or LCD screen.
Cleaning the LCD screen
Carefully wipe the surface of the LCD screen with a soft, lint-free cloth using ethanolic
liquid, such as a screen cleaner for LCDs, or by using a screen wipe specially designed
for the purpose. When cleaning the LCD screen, please take the following precautions:
• Don’t use harsh abrasives, such as paper towels.
• Don’t apply liquids directly to the screen.
• Don’t use ammonia-based cleaners and solvents, such as acetone.
Cleaning the internal fans
The unit’s internal fans need to cleaned regularly to remove the build of dust, dirt etc.
We recommend that they are cleaned at least once a year, provided the unit has been
operated under normal conditions. However, if the operating conditions are more
adverse or extreme, for example, if the unit is operated in the vicinity of smoke
machines, new carpets etc., this frequency should be increased accordingly.
This procedure must be carried out by a fully qualified service engineer.
