INSTALLING THE DRAIN
Using Hard Pipe:
• Install a 3/4" PVC slip x 3/4" MNPT PVC fitting to the
dehumidifier and use 3/4" nominal PVC Schedule 40
pipe to run the condensate line to the nearest floor
drain or to an outside location that slopes away
from the building.
• Always maintain a constant downward slope in
drain piping. Ensure that drain tubing does not
interfere with removal of the side panel or filter door.
• Do not use metal fittings and only hand-tighten
threaded fittings. PTFE thread seal tape is
recommended for threaded connections.
• Install a tee or three-way elbow at the dehumidifier
outlet with a small, capped vertical tube (do not
cement cap in place) to allow for cleaner to be
poured into the drain line
(see Figure 14) .
• PVC primer and cement is recommended for
slip-fit connections (do not cement threaded
connections).

Using Flexible Tubing:
• Install the provided 3/4" NPT x 3/4" hose barb fitting
and use 3/4" flexible drain tubing. Hand-tighten the
fitting to the dehumidifier. PTFE thread seal tape is
recommended for threaded connections.
• Always maintain a constant downward slope
from the dehumidifier to the nearest floor drain or
condensate pump, and do not allow soft tubing to
curl up, which may result in air lock.
INSTALLING DUCTWORK
• Use insulated duct when the dehumidifier is located
in an unconditioned space, such as an attic, garage
or crawl space, or if connecting a fresh air duct to
the dehumidifier ductwork.
• Use zip ties, mastic, and tape as needed to seal
the duct connections to the dehumidifier and to
seal the insulation sleeves to prevent condensation
inside the ductwork.
Connecting the dehumidifier to your HVAC system will
pull air to be dehumidified from the whole home and
similarly will discharge air to the whole home. Make sure
the duct system pressure the dehumidifier will have to
operate against does not exceed 0.4" Water Column
(WC) for Model E080 and 0.6" WC for Models E100/E100H.
Measure the system pressure when the HVAC fan is
operating at the highest airflow (speed) setting.
There are not always readily available locations on the
HVAC duct system for connecting 10" ducts, and some
local codes do not allow ducting to the return side of
the HVAC system. If so, another option is to install just
the discharge of the dehumidifier to the HVAC system
or to use dedicated registers for both the inlet and
discharge of the dehumidifier.
