AWARNING
AVERTISSEMENT
Danger of electric shock. Always disconnect power source before servicing. Do
not install in a cooking area or make line-voltage electrical power
connections directly between this unit and any appliance .
UNIT LABEL (TYPICAL)
INSTALLATION
Damper(s) are factory installed and fully wired in all ERV models.
Outdoor Installations: For H and F orientations, attach ductwork to the ERV
cabinet or to the outer flanges of the damper frame.
For R and V orientations, attach ductwork to the curb before installing the
ERV to the curb. Indoor Installations: Attach ductwork directly to the ERV
cabinet or to the outer flanges of the damper(s) frame.
NOTE : This unit is an Energy Recovery Ventilator, or ERV. It is commonly referred to throughout this manual as an ERV.
DAMPER LOCATIONS ON OUTDOOR ERVS
Damper(s) are located at the Outside Air (OA) location (underneath the air
intake hood) and at the Room Air (RA) location for all units except HE07,
HE10, HE1.5X, HE6X, and HE8X. The OA and RA locations are marked on the
outside of the ERV. The damper actuators are located inside the ERV and are
accessible through the ERV core door.
DAMPER LOCATIONS ON INDOOR ERVS
Damper(s) are located at the Outside Air (OA) location and at the Room Air
(RA) location for all units except HE07, HE10, HE1.5X, HE6X, and HE8X. The OA
and RA locations are marked on the outside of the ERV. The damper actuators
are located inside the ERV and can be accessed through the ERV core door.
NOTE : In some ERV models, the intake hoods must be installed over the damper.
DAMPER LOCATIONS IN HE07, HE10, AND HE1.5X ERVS
Damper(s) are located at the Supply Air (SA) location and at the Exhaust Air
(EA) locations. The FA and EA locations are marked on the outside of the ERV.
The damper actuators are located inside the ERV. The SA and EA actuators are
accessible through the left door.
DAMPER LOCATIONS IN HE6X AND HE8X ERVS
Damper(s) are located at the Outside Air (OA) location and at the Exhaust Air
(EA) locations. The OA and EA locations are marked on the outside of the ERV.
The damper actuators are located inside the ERV. The OA actuator is accessible
through the ERV core door, while the EA actuator is accessible through the
right ERV blower door.
OPERATION
SEQUENCE OF OPERATION
At start-up
When the ERV receives an external call for ventilation, the blowers will
not turn on immediately.
The damper(s) are opening inside the ERV. It will take approx. 45 seconds to
open, at whichpoint a low voltage end switch in the actuator closes. The end
switch call on the VFD or the motor starter to turn on the blower.
NOTE : Dampers(s) are spring return and are in the shut or closed
position when the ERV is not operating.
At shut-down
When the ERV no longer calls for ventilation, the damper(s) will begin
closing (spring return). When the damper(s) are approx. 75% closed (15-20
seconds), the end switch will open and the blowers will stop.
NOTE: Dampers(s) return to the closed position if power to the ERV is
interrupted.
CAUTION
The blowers will still be spinning, but will stop. Do not try to manually
slow the fans down.
COMMISSIONING
Check all dampers and insure they open and close properly and without
binding. Apply power to motorized dampers to ensure the actuator opens and
closes the damper as designed.
To check damper operation without operating blowers:
NOTE : Check for unobstructed operation.
-
Turn off power to unit by rotating unit disconnect switch to “off” position (Warning! Line side of disconnect switch is still hot!)
-
Temporarily disconnect motor control(s):
a. Units with one or two Motor Starters: Disconnect blue low-voltage wire leading to transformer from terminal 96 of all of the motor starters.
b. Units with one or two Variable Frequency Drives (VFDs): Disconnect low-voltage wire leading to damper end switches from terminal 9 or 12 of all VFDs. Alternately use VFD keypad to set motor speed to 0 (WARNING: control equipment you install in the next step might over-ride this setting).
c. Units with MOLEX plugs connecting the motor wire harnesses to power and control wire harnesses: Unplug the low voltage motor control harnesses (two pin connection).
NOTE : For indoor units, the dampers are located inside the ductwork attached to the unit. Therefore, check damper operation after installing the first lengths of ductwork that cover the damper, but before completing the ductwork and making it inaccessible. -
Consult unit wiring schematic and make temporary or permanent connections of jumpers or controls to call for unit operation.
-
Turn on power to unit.
-
Using the jumper(s) or controls installed in step 3, call for unit operation. Dampers should open.
-
Disconnect power to the unit; dampers should close.
-
Reconnect the motor control(s) by reversing what you did in Step 2, above.
NOTE : This procedure does not confirm proper operation of the actuator end switches.
MAINTENANCE
Damper bearings are an impregnated bronze material and do not need
lubrication.
Clean out wind-born debris such as leaves from the sealing surfaces of OA
dampers in rooftop units at the same time you change filters.
TESTING AND REPLACEMENT OF DAMPERS AND ACTUATORS
If dampers fail to open at the signal for ventilation, disconnect power to
the unit. To determine if the actuator is defective, disconnect the 24v power
source. Connect the actuator directly to a known 24v power source with an
appropriate cable. If the damper operates correctly, the problem is in the
internal wiring connections.
TROUBLESHOOTING
Damper:
Low air flow: Unit damper(s) not fully open, check for unobstructed operation.
Clear any obstruction; re-tighten the actuator U-clamp; or replace damper
actuator.
Dampers open, but blowers don’t run: check end switch closure.
FACTORY ASSISTANCE
In the unlikely event that you need assistance from the factory for a specific
issue with the ERV or its Isolation Damper Option, make sure that you have the
information called for in the Unit Records pages at the front of this manual.
The person you speak with at the factory will need that information to
properly identify the unit and the installed options.

Remember that RenewAire Customer Service can only assist with the ERV and its options, it cannot resolve engineering issues that result from air handling system design by others.
About RenewAire
For over 40 years, RenewAire has been a pioneer in enhancing indoor air
quality (IAQ) in commercial and residential buildings of every size. This is
achieved while maximizing sustainability through our fifth-generation, static-
plate, enthalpic-core Energy Recovery Ventilators (ERVs) that optimize energy
efficiency, lower capital costs via load reduction and decrease operational
expenses by minimizing equipment needs, resulting in significant energy
savings. Our ERVs are competitively priced, simple to install, easy to use and
maintain and have a quick payback. They also enjoy the industry’s best
warranty with the lowest claims due to long-term reliability derived from
innovative design practices, expert workmanship and Quick Response
Manufacturing (QRM).
As the pioneer of static-plate core technology in North America, RenewAire is the largest ERV producer in the USA. We’re committed to sustainable manufacturing and lessening our environmental footprint, and to that end our Waunakee, WI plant is 100% powered by wind turbines. The facility is also one of the few buildings worldwide to be LEED and Green Globes certified, as well as having achieved ENERGY STAR Building status. In 2010, RenewAire joined the Soler & Palau (S&P) Ventilation Group in order to provide direct access to the latest in energyefficient air moving technologies.
