CWM (L) USER MAINTENANCE
ISOLATE THE UNIT ELECTRICALLY BEFORE COMMENCING ANY MAINTENANCE WORK
In order to maintain maximum efficiency of this unit, it is important that the filters behind the return air
grilles are cleaned regularly.
To remove filters:
Clean the filters by washing in tepid water, vacuuming or by tapping gently outside the building.
To replace filters:
THE UNIT SHOULD ALWAYS BE USED WITH A FILTER. FAILURE TO DO SO WILL CAUSE A
DECLINE IN UNIT PERFORMANCE AND MAY RESULT IN MALFUNCTION
We recommend that, in order to prolong the life and maintain performance of CWM (L) units, they are
regularly serviced by an TEV Ltd installer/dealer.
