SET UP & USE

INTERNAL PUMP MODE

The internal pump allows the unit to operate without having to empty the bucket 

and requires the installation of the included pump drain hose kit. To install the 
kit, remove the drain cap on the back of the unit (see Fig. 6 on page 12). Insert 
the included gasket into the front of the included pump adapter (see Fig. 7 on 
page 12). Force the included CLEAR drain hose on to the pump adapter and turn 
adapter clockwise on to the garden hose type nozzle on the back of the unit (see 
Fig. 8 on page 12). Once securely installed, lead the drain hose to a nearby drain, 
sink or out a window. Turn on the dehumidifier and press the PUMP button to 
activate the internal pump. The “PUMP” LED indicator should illuminate.

NOTE:

  Be aware that a small internal tank must fill before the pump will function 

and operation may be intermittent depending on the amount of humidity 
in the air at the time. Water can be pumped up to 16’ in height from base 
of unit. Make sure there are no kinks or knots in the hose.

NOTE:

  Even once you activate the internal pump, you may not get water running 

out of the drain hose right away as there is a small, internal tank which 
must fill first. Also, the water will not run out of the drain hose on a 
continuous basis unless the dehumidifier has been placed in a very high 
humidity area. Otherwise, it will power on and off as needed based on the 
home comfort mode set by the user and the ambient humidity level in the 
area.

Water can be pumped up to 16’ in height from base of drain plug. Make sure 

there are no kinks or knots in the hose. ONLY use included clear drain hose when 
utilizing the internal pump.
