INSTALLATION
Before bringing power to the unit check unit nameplate to confirm it matches the voltage and
phase of the power you are supplying. Remember that your field connections need to be accessi-
ble for inspection.
CAUTION
5.3 ELECTRICAL REQUIREMENTS
Electrical Options and Ratings are identified on the Unit Label (located near electrical box). Find
the complete Unit Model Number in the lower left corner of the Unit Label.
NOTE: If your unit
is equipped with
EC Motors, please
refer to “EC Motor Supple-
mental Manual” for more
detail.
Use conduit, strain reliefs,
etc. as required by code to
secure the field wiring.
NOTE: Standard
HE1.5XRT with
single phase original
equipment motors
are NOT suitable for use
with solid state speed
control.
NOTE: Le HE1.5XRT
avec moteurs d’équi-
pement d’origine
monophasés sont adaptés
pour une utilisation avec
regulateur de vitesse elec-
tronique.
5.2.2 Duct Insulation
If the inside ducts run through unconditioned spaces, they must be insulated, with a sealed
vapor barrier on both inside and outside of insulation.
5.2.3 Use Dampers to Set and Balance Airflow Rates
In most applications, the airflow rate for both the Fresh Air and the Exhaust Air should be
roughly equal (or “balanced”) for best performance of the HE1.5XRT Unit. See unit specification
sheet for CFM/ESP curves for available horsepower motors.
5.3.1 Factory-Recommended Electric Service Entry
Knockouts are provided in the bottom of the E-box for entry of high-voltage power supply
wiring. Install the wiring in accordance with local codes and provide strain relief at the E-box
opening. Wiring is then terminated on the top of the disconnect switch.
Low-voltage control wiring is to enter the E-box through the knockout in the bottom of the
E-box. Provide strain relief as needed.
High-voltage supply wiring is to be connected on the top side of the disconnect switch. See
image below.
