There is a lever for a vent open or close.... Well where is the vent and what does this do

Asked by: Kal225
The vent lever is located behind the front grille above the control knobs on the LG 12000 BTU Window Air Conditioner, Cooling & Heating, Model # LW1216HR. As per the instructions on page 15 of your owner's manual, "Before installing the front grille, pull out the vent control lever located above the unit control knobs". The lever then has to be guided carefully through the grille as you push the grille in to snap it back in place. Page 18 has a description for the vent lever which opens the damper so room air can be drawn outside when the vent lever is pulled out to the 'open' position. It has to be pushed in to the 'closed' position in order to maintain the best cooling conditions...^IFV

Where is the drainage at ? Its been leaking in the front

Asked by: June23
This air conditioner is equipped with a slinger fan. The fan has an outer ring that runs through the water that collects in the base pan. That condensate is then picked up by the fan and expelled onto the condenser coils, making the machine operate more efficiently. In humid weather, excess water may cause the base pan to overflow. Remove the drain cap, from the back of the cabinet, and secure a drain pipe in order to drain the excess moisture. Information about this can be found on page 19 of the owner’s manual. ^CP
