Maintenance

NOTE

JAKKA Controllers for this units have a preset timer to monitor filter occupancy according

to factory set timer. Remote controller informs the user to check the filters. After the

filters are cleaned by the user, filter warning alarm must be reset.

Clean the filter with a vacuum cleaner. To remove dense dust build-ups, prepare

a solution with cold water and natural detergent or soap powder and submerge the

filter in the solution. Later pull out the filter from the solution and leave it to dry. In any

case, do not scrub or apply force on the filter material. After it is completely dry, mount the

filter to the unit, close the service door and tighten the screws thoroughly.

NOTE

It may be handy to keep spare clean and dry filters for quick replacement of dirty filters to

minimize unit downtime for filter maintenance.
