Installation Steps (continued)
5
Installing the condensation drain line
Insert the threaded drain adapter through the bottom of
the unit and hand tighten the plastic nut supplied with
the drain kit.
Use a wrench to tighten the nut another half turn to
ensure a complete seal.
Install the condensate tubing by pushing the clear
plastic tubing over the drain adapter.
Make a condensate trap by looping the clear plastic
tubing. This loop will prevent foul odors from entering
the unit.
Use a condensate pump if you don’t have access to
the floor drain.
Drainless Application
NOTE: If installing an ERV unit (VNT5150E1000, VNT5200E1000, VNT5070E1000) in a region where
the outdoor temperature does not drop below freezing, the condensate drain line does not need
to be installed and the unit may be installed as a drainless application.
1. Insert the threaded drain adapter through the bottom
of the ERV with the drain connection inside of the unit
as shown in the figure.
2. Fit the rubber washer over the drain adapter and then
attach the plastic nut.
3. Hand tighten the plastic nut supplied with the drain kit.
4. Use a wrench to tighten the nut another half turn to
ensure a complete seal.
5. Attach the drain cap to the drain adapter inside the
unit.
