Routing the tubing out of the unit:
Cut a small piece of 1/2” tubing and connect one
end to the drip tray port and the other to a 90°
fitting. (This will direct the tubing toward the
back of the unit where the tube will exit the
unit.) Be sure to extend the tubing far enough
outside the housing to extend through the wall
if necessary.
If routing out of the rear:
Cut a piece of tubing
long enough to protrude out of the knockout on
the back side of the unit.
If routing out of the bottom:
Cut a piece of
tubing long enough to reach the knockout in
the bottom of the unit and install the supplied
90° fitting. (This will direct the tubing out of the
bottom of the unit without the risk of kinking
the tubing.)
DO NOT USE TEE WHEN ROUTING
OUT OF THE BOTTOM.
Routing to discharge location if routed out
of the bottom:
Connect the drain line directly to the second 90°
barb fitting previously installed. Route the drain
line to an appropriate drain location. No tee is
required if draining through the bottom of the
unit.
NOTE:
The fitting should be placed
vertically with the 3” cutout facing
up.
Failure to install the drain line
voids the warranty.
To prevent mold from growing,
allow the drain line to hang
above the water line.
WRONG:
Drain line is under water.
DRAIN LINE
Drain Line
Each evaporator comes with a drain line connection tee and two 90° fittings. Each unit is equipped with a 1/2” OD barbed fitting
coming from the drip tray. (
NOTE:
1/2” ID clear PVC tubing will need to be purchased and installed by the installing technician.)
Installation of the drain line is mandatory, whether it leads through the wall and out of the cellar or remains inside the cellar.
During operation, the cooling system will strip excess water from the air in order to maintain the proper level of humidity within
the cellar. However, in extreme humidity, additional condensate will be removed; thus the drain line will prevent overflow and
leakage by discharging the excess condensate.
Condensation Drain Line (not provided, but required)
The condensation drain line tube moves excess condensation from the evaporator units to a proper discharge
location. It is important for the drain line tube to be properly connected in order to prevent leakage and other problems associ-
ated with excess condensation. (Each evaporator requires its own dedicated drain line.)
Failure to use the condensation drain line tube will void the warranty on the unit.
Routing to discharge location if routed out of the rear:
Insert the middle barb of the barbed tee fitting into the end of the drain
line coming from the evaporator. Rotate fitting so tee is in the orientation
shown in the diagram below. Connect a 3-inch piece of 1/2” drain line to
the barb on top. Connect the remaining “long” piece of drain tubing to
the bottom barb of the tee. Route the drain line to an appropriate drain
location.
