NEC RC122 Owner's Manual - Air Filter Cleaning

AIR FILTER CLEANING
The air filter should be checked at least twice a month to see if cleaning is necessary. Trapped
particles in the filter will build up and block the airflow. This reduces the cooling capacity and also
causes an accumulation of frost on the cooling coils.
1. Open the inlet grille upward by pulling out the bottom of the inlet grille.
2. Remove the air filter from the front grille assembly by pulling the air filter up slightly.
3. Wash the filter using lukewarm water below 40°C(104°F).
4. Gently shake the excess water from the filter completely. Replace the filter.
1. Pull down front grille from the cabinet top.
2. Push front grille's tips toward the cabinet in
order to insert front grille's tabs into the
cabinet.
3. Open the inlet grille.
4. Tighten the screw through the front grille into
the base pan.
5. Close inlet grille.
HOW TO USE DRAIN
First, be sure to insert the drain pipe into base pan before installation.
The air conditioner must be installed with a slight tilt to the outside for
proper water drainage.
Generally the air conditioner may drain condensation through the
drain pipe. (See description)
