1. Before servicing or cleaning the unit, switch
power off at disconnect switch or service panel
and lockout/tag-out to prevent power from being
switched on accidentally. More than one discon-
nect switch may be required to de-energize the
equipment for servicing.
2. This installation manual shows the suggested
installation method. Additional measures may be
required by local codes and standards.
3. Installation work and electrical wiring must be
done by qualified professional(s) in accordance
with all applicable codes, standards and licens-
ing requirements.
4. Any structural alterations necessary for instal-
lation must comply with all applicable building,
health, and safety code requirements.
5. This unit must be grounded.
6. Danger of severe injury to bystanders and dam-
age to unit or property if high winds move this
unit. Secure this unit to the building!
7. Sufficient air is needed for proper combustion
and exhausting of gases through the flue (chim-
ney) of fuel burning equipment that might be in-
stalled in the area affected by this equipment. If
this unit is exhausting air from a space in which
chimney-vented fuel burning equipment is locat-
ed, take steps to assure that combustion air sup-
ply is not affected. Follow the heating equipment
manufacturer’s requirements and the combus-
tion air supply requirements of applicable codes
and standards.
8. Use the unit only in the manner intended by the
manufacturer. If you have questions, contact the
manufacturer.
9. This unit is intended for general ventilating only.
Do not use to exhaust hazardous or explosive
materials and vapors. Do not connect this unit to
range hoods, fume hoods or collection systems
for toxics.
10.When cutting or drilling into wall or ceiling, do
not damage electrical wiring and other hidden
utilities.
RISK OF FIRE, ELECTRIC SHOCK, OR INJURY. OBSERVE ALL CODES AND THE FOLLOWING:
WARNING
The unit’s fresh air inlet should be at least 10’ away from any exhaust, such as dryer vents, chimneys,
furnace and water heater exhausts, or other sources of contamination or carbon monoxide. Do not locate the
fresh air inlet where vehicles may be serviced or left idling. Never locate the unit inside a structure.
Danger of damage or severe injury if high winds move this unit. Secure unit to structure. Observe local code
requirements at a minimum.

WARNING
DANGER OF INJURY
OR DAMAGE.
The motors in this unit must not be
run at an amperage that exceeds
the motor’s rated full load amps.
It is the installer’s responsibility to
measure the operating amperage
of each motor. If the full load amp
rating is exceeded, the amp draw
must be reduced by reducing
airflow with an external damper.
Failure to make this adjustment
may result in unsafe motor
winding temperatures or tripping
of the supplied motor starter’s
overload relay motor protection
devices set at full load amps.
HE1XRT INFO
Three phase motors are NOT suitable for use with
solid state speed control. If speed control is desired
use the VFD option.
Single phase ECM motors are NOT suitable for use
with solid state speed control. They already have
speed control built into the motor electronics.
Moteurs de trois phase ne convient pas pour utilisation
avec regulateur de vitesse electronique. Si la régulation
de vitesse est souhaité, utiliser l’option VDF.
Moteurs d’une phase de l’ECM ne conviennent pas pour
une utilisation avec regulateur de vitesse electronique.
Ils ont déjà le contrôle de vitesse intégré dans le moteur
électronique.
WARNING
Danger of Electrical Shock when servicing an installed unit.
ALWAYS DISCONNECT POWER SOURCE BEFORE SERVICING! More than one disconnect switch may be required.
Proper Wiring Size Selection and Wiring Installation are the Responsibility of the Electrical Contractor.
WARNING
Motor may have a manual reset thermal protector.
Disconnect power before servicing or resetting motor
thermal protector. Use caution, motor may be hot.Allow
the motor to cool before resetting the thermal protector.
If the motor thermal protector tripped, correct the
issue that caused the motor to overheat (e.g. over
motor rated amperage or locked rotor).
If the motor has a manual reset thermal protector, the
red thermal protector reset button is located on the
motor body, on or near the lead end of the motor. If the
button does not reset, the motor may still be too hot.
Allow the motor to fully cool to reset the thermal pro-
tector, you should feel or hear a click when the ther-
mal protector resets while pushing the reset button.
WARNING
RISK OF INJURY OR DAMAGE. Danger of injury if unit starts
unexpectedly. Switch power off
at service disconnect. Lock-out/
tag-out the disconnect.

It is the installer’s responsibility to make sure that
the screws or bolts used for securing the units
are properly selected for the loads and substrates
involved. Secure the HE1XRT so that it cannot fall
or tip in the event of accident, structural failure or
earthquake.SeeRiggingInformationforunitweight.
RenewAire strongly recommends that you secure
rooftop units properly to the building structure.
Strong winds, tornados, and hurricanes can and
do displace or remove rooftop equipment from
rails or curbs. When this happens, the equipment,
adjacent roof structure, and even vehicles parked
near the building can be damaged, and rain
typically enters the building. The equipment is put
out of service and the collateral damage can be
very expensive.
Provide Adequate Service Access for Maintenance.
The HE1XRT will require regular filter and core
inspections. Install the HE1XRT where you can
open the doors for cleaning the core and replacing
the filters, and where you can get at the wiring for
installation and service.
CAUTION
CAUTION
Provide service access to the unit to allow for cleaning the core and filter.
