Clean your air conditioner occasionally to keep it looking new. 
Be sure to unplug the unit before cleaning to prevent 
shock or fire hazards:

The air filter should be checked at least once a month to see if 
cleaning is necessary. Trapped  particles in the filter can build 
up and cause an accumulation of frost on the cooling coils.

Grasp the filter by the center and pull up and out.
Wash  the  filter   using   liquid  dishwashing   detergent  and 

    warm  water.  Rinse filter  thoroughly. Gently  shake  excess  
    water  from the filter. Be sure  filter is  thoroughly dry  before 
    replacing.

Or, instead of washing you may vacuum the filter clean.

Be sure to unplug the air conditioner to prevent shock or fire

    hazard.  The  cabinet   and  front  may   be   dusted   with  an 
    oil-free cloth  or washed with a cloth dampened in a solution 
    of warm water and mild liquid dishwashing detergent. Rinse
    thoroughly and wipe dry.

Never use harsh cleaner, wax or polish on the cabinet front.
Be  sure  to  wring excess water from the cloth before wiping 

    around  the controls. Excess water in or around the controls 
    may cause damage to the air conditioner.

Plug in air conditioner.

If   you  plan  to  store  the   air  conditioner  during  the  winter, 
remove    it   carefully   from   the   window   according   to   the 
installation  instructions. Cover it with plastic or return it to the 
original carton.
NOTE: To prevent rust or electrical connetions from being 
damaged,  store air conditioner in an upright position and 
in a dry place.
