MAINTENANCE
Installing Air Filter and Air-Inlet Grid:
1. Mounting the filter: opposite of dismantling the filter (as shown
in Fig. 3 on previous page).
2. Mounting the air inlet grid: as shown in the right figure, clip the
locks on the grid as directed by the arrows, put the side with
the hinges into the lock port, and then put the side with locks
into the panel frame. Release the locks to position the grid after
determining that the grid is flush with the bottom of the panel
frame.
Cleaning the air outlet vanes and the frame:
• Wipe them with a soft dry cloth.
• Water or neutral dry cleaner is recommended if the dust cannot be removed.
Cleaning louvers:
• Care should be taken while cleaning the louvers to avoid damage. Use damp cloth and mild detergent.
