Placement of the HE4XRT
The HE4XRT is designed for installation on a roof or other outside
location.
Select a location that is central to the inside duct runs, and close
to any other air handler that might be part of the system.
The fresh air inlet should be at least 10’ away from exhausts such
as dryer vents, chimneys, furnace and water heater exhausts, or
other sources of contamination or carbon monoxide.
Provide service access to the unit to allow for cleaning the core
and filter.
The HE4XRT is available from the factory in four different
configurations to meet different connection requirements:
Mounting the HE4XRT
On Roof Curbs:
The base of the HE4XRT Unit is designed for installation on our
optional Roof Curb. See drawing below.
Before installing HE4XRT, apply roofing and counterflashing to
Roof Curb as per standard practice.
Install appropriate gasket on top of Roof Curb.
Set HE4XRT in place. We recommend bolting through sides of unit
base into the Roof Curb to secure the unit against high winds.

Review drawing of Roof Curb and specify Equipment Rail to fit.
Before installing HE4XRT, apply roofing and counterflashing to
Equipment Rails as per standard practice.
Set HE4XRT in place. We recommend bolting through sides of unit
base into the Equipment Rails to secure the unit against high winds.
