Front Cover Installation
Reinstall the front cover by hooking the top over the rail along the chassis top,
then pushing it in at the bottom.
4. Drain
For cooling or cooling with PTC heaters, the condensate water is blown past the
condenser and will be evaporated. It is not necessary to use any drain kit or
assembly for these models.
For heat pump units, we have provided a valve that will open when the temperature
reaches 50°F (10°C). This drain is located in the pan between the compressor and
the condenser. A drain kit maybe connected to the hole in the wall sleeve if needed.
The condensate water will be blown past the condenser eliminating as much
condensate as possible.
5. Test Operation
Connect unit to power source, check to see if the operational mode buttons work properly.
Check to see if the room temperature control and the function control work properly.
Check if there are abnormal sounds during operations.
Check the cool air at the outlet, the unit is operating normally when the temperature of air
outlet is 10 °F and 18 °F below the outdoor temperature.
