Drain Maintenance – Base

Located at the rear of each unit is a drain hose,

which removes the condensation from the

evaporator coil and deposits it into a drain pan

for evaporation (see Figure 3).

Figure 3

Location of Drain hose and Drain Pan

If excessive water accumulates inside the unit,

check to see that the drain hose is connected

from the evaporator housing to the drain pan. If

water accumulates underneath the unit, check

to see that the drain hose is located above the

drain pan.

A level unit is essential for proper drainage. Be

sure to provide a level surface below the unit,

especially if the floor is not level. Keep the drain

pan free from dirt, dust and debris to prevent water

from backing up and overflowing from the drain

pan onto the floor.
