RenewAire DN-Series User manual

This unit should be started up for a brief period immediately after high and low-voltage wiring are complete. The purpose of
the intitial start-up is only to verify correct fan rotation direction and that the dampers are opening and closing properly. After
the unit has been run for a brief period, it is to be shut back down until the entire installation is complete. The unit is not to be
used for building ventilation before the building has been completed.
PRIOR TO UNIT START-UP:
UNIT START-UP:
The unit must be in its final location.
The unit must have a complete set of filters in place.
High-voltage supply wiring must be complete.
All low-voltage wiring, including field-installed sensors, must be completed.
All debris or construction materials must be removed from the unit.
All doors and access panels must be in place.
Initial start-up should not be performed if the air is laden with construction dust. Filters will quickly become dirty and require
changingfor other subsequent testing.
If this unit was purchased with a Remote User Terminal (RUT) for the controller, connect the RUT and perform start-up steps
with the RUT. If there is no RUT, perform the start-up steps by using the buttons on the Integrated Programmable Controller.
WARNING
ARC FLASH AND ELECTRIC SHOCK HAZARD
All DN models operate on high voltages that can cause
severe electric shock. Some models use high voltages that
are capable of causing dangerous arc flash. Whenever ac-
cessing any part or component of the DOAS, disconnect all
electric power supplies, verify with a voltmeter that electric
power is OFF and wear protective equipment per NFPA
70E when working within the electric enclosure. Failure to
comply can cause serious injury or death.
The unit disconnect switch contain 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 voltmeter. Refer to unit elec-
trical schematic.
Follow all local codes.
RISK OF ELECTRIC SHOCK OR EQUIPMENT DAMAGE
Whenever electrical wiring is connected, disconnected or
changed, the power supply to the unit and its controls must
be disconnected. Lock and tag the disconnect switch or
circuit breaker to prevent accidental reconnection of electric
power.
CAUTION
CAUTION
RISK OF CONTACT WITH HIGH-SPEED MOVING PARTS.
Disconnect all local and remote power supplies, verify with
