HE-Series Outdoor
ERV
Standard HE1.5XRT with single phase original equipment
motors are NOT suitable for use with solid state speed
control.
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.
WARNING
Le HE1.5XRT avec moteurs d’équipement d’origine mono-
phasés ne convient pas pour une utilisation avec regulateur
de vitesse electronique.
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 électro-
nique.
AVERTISSEMENT
RISK OF INJURY OR DAMAGE.
Motor may have a manual reset thermal protector. Dis-
connect 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 amper-
age 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 protector, you should feel or hear
a click when the thermal protector resets while pushing the
reset button.
WARNING
ARC FLASH AND ELECTRIC SHOCK HAZARD
Arc flash and electric shock hazard. Disconnect all electric
power supplies, verify with a voltmeter that electric power
is off and wear protective equipment per NFPA 70E before
working within electric control enclosure. Failure to comply can
cause serious injury or death.
Customer must provide earth ground to unit, per NEC, CEC and
local codes, as applicable.
Before proceeding with installation, read all instructions,
verifying that all the parts are included and check the
nameplate to be sure the voltage matches available utility
power.
The line side of the disconnect switch contains live high-
voltage.
The only way to ensure that there is NO voltage inside the unit
is to install and open a remote disconnect switch and verify
that power is off with a volt meter. Refer to unit electrical
schematic. Follow all local codes.
WARNING
RISK OF ELECTRIC SHOCK OR EQUIPMENT DAMAGE
Whenever electrical wiring is connected, disconnected or
changed, the power supply to the ERV and its controls must
be disconnected. Lock and tag the disconnect switch or circuit
breaker to prevent accidental reconnection of electric power.
CAUTION
RISK OF CONTACT WITH HIGH SPEED MOVING PARTS
Disconnect all local and remote power supplies, verify with
a voltmeter that electric power is off and all fan blades have
stopped rotating before working on the unit.
Do not operate this unit with any cabinet panels removed.
CAUTION
