Installing the ERV5-130
It is important to isolate the mounting bracket from the at-
tached surface to minimize vibration. Use the hardware
provided (see “Table 1. Bag Assembly Contents” on page
3) to attach the mounting brackets to the unit.
IMPORTANT
Do not drill additional holes in the ERV.

Installing the Drain Connection
During a defrost cycle, the HRV unit may produce some
condensation. This water should flow into a nearby drain,
or be taken away by a condensate pump.

CAUTION
Do not use sealant when installing the drain spout.
CAUTION
Potential Freeze Conditions leading to Water Damage.
Condensation can accumulate and cause water damage
to equipment, finished surfaces and structures.
Do not install ERV/HRV or route condensate drain lines in
areas that can be subjected to freezing.
Potential Water Damage.
Unit must be installed level to ensure proper condensation
drainage. Avoid installing units above areas or equipment
that are sensitive to water damage. Connect condensate
drains in accordance with national and local codes. P−
Trap and tubing must be located below the HRV door with
a minimum of ¼” per foot downward slope away from unit.
All ERV/HRV cabinets (except ERV5-130) have pre-
punched holes for the drain as illustrated in “Figure 28.
Drain Holes and P-Trap (ERV/HRV)”.
1.
Insert the drain spout through the hole in the drain pan.
2.
Be sure to install the
O-ring
(if supplied) which seals
each spout to the pan.
3.
Tighten the nut which holds the drain spout in place.
Construct a P−Trap using the plastic tee connector as illus
-
trated in “Figure 28. Drain Holes and P-Trap (ERV/HRV)”.
1.
Cut two lengths of hose and connect each piece to an
end of the
T
fitting, then connect the other ends to the
two drain spouts.
2.
Position the T fitting to point upward, and connect the
drain line. Tape or fasten base to avoid any kinks,
creating a ˆtrap.˜
3.
Pour a cup of water into the drain pan of the HRV after
the drain connection is complete.
This creates a water seal which will prevent odors from be-
ing drawn up the hose and into the fresh air supply of the
HRV.
NOTE: Secondary drain pan may be required to protect
from condensate leakage, especially when unit is
installed above living space.
Installing Optional Plug (ERV5-150-TPD and
ERV5-175-TPD Unit Only)
The plugs are located in the ERV manual bag. The plugs
will be installed into the two holes located in the bottom tray
of the ERV. They must be inserted from the inside of the
unit to ensure the holes are fully sealed, see detail below.
