6. Maintenance
Air Filter Replacement
1. Switch off the power supply to the Control Unit.
2. Disconnect the power lead and air hoses.
3. Place the Control unit on a flat surface with back panel uppermost (place soft cloth under unit to prevent scratches).
4. Carefully remove air filter cover, remove and discard the filter material and fit new filter (there may be a small locking screw –
use a small Phillips head screwdriver to remove).
5. Refit the air filter cover to the Control unit. The Control unit is now ready for re-connection.
Good filter maintenance is critical to maintain your system in optimal operating condition. Failure to keep the filters clean will result
in system downtime and increase repair costs. It is recommended that the air filter be replaced annually. Replacement air filters are
available from an authorised local Direct Healthcare distributor. Please see contact information on cover.
Fuse Replacement
1. Switch off the power supply to the Control Unit.
2. Remove the power cord from the electrical socket on the side of the base of the Control Unit.
3. Insert a small Flat head screwdriver into the groove and turn anti-clockwise (quarter turn).
4. Remove the “blown” fuse from the fuse holder clip and discard.
5. Insert a new fuse into the plug. Push against the force of the spring and turn clockwise with the screwdriver (quarter turn).
Ensure the replacement of fuses is carried out accordance with local legislation.
