Normal Sounds
When your air conditioner is operating normally, you may hear sounds such as:
•
Droplets of water hit the condenser, causing a
pinging or clicking sound. The water droplets
help to cool the condenser.
•
Air movement from the fan.
•
Clicks from the thermostat cycle.
•
Vibrations or noise due to poor wall or window
construction.
•
A high-pitched hum or pulsating noise caused
by the modern high-efficiency compressor
cycling on and off.
Drain Cup Installation and Operation
Your air conditioner uses a system where the water removed from the indoor air is channeled to the outdoor side
of the unit. The outdoor fan blade has a “slinger” ring attached to it that dips into the water and slings the water
onto the outdoor coil surface. This is the sound of water you hear during normal operation. The water quickly
evaporates on this warm surface and improves the efficiency of your air conditioner. In normal conditions the unit
can evaporate the water as fast as it is removed from the indoor air.
When it is in very humid weather, excess amounts of water may drop off the unit chassis. You could install the
condensate drain cup provided with the unit if this becomes a problem. See below Installation Instructions.
•
Remove the unit chassis from the outer case. Refer to Page 6.
•
Insert the condensate drain cup through the recessed 1/2” hole on the back center of the outer case.
•
Place a 1/2” diameter hose or tube (not provided) on the drain cup bottom spout. The hose allows you to
route where you want the excess water to go.
•
Reinsert the unit chassis into the outer case. The unit basepan overflow hole will be positioned directly
above the drain cup and will collect any water that might run out.
