HE1.5XIN INFO

For over 30 years, RenewAire has been a pioneer in enhancing indoor air quality (IAQ) in commercial
and residential buildings of all sizes. This is achieved while maximizing sustainability through fifth-gen­eration, enthalpic-core, static-plate Energy Recovery Ventilators (ERVs) that improve 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 lowest warranty claims
due to long-term reliability derived from innovative design practices, expert workmanship and Quick
Response Manufacturing (QRM).

As the first producer of static-plate core technology in North America, RenewAire presently has over
180,000 units in operation and is now one of the largest ERV companies in the world. We’re committed
to sustainable manufacturing and lessening our environmental footprint, and to that end our Madison,
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 HVAC technologies. For more information, visit: www.renewaire.com.

INSTALLATION

DUCTS TO THE OUTSIDE

The exhaust outlet and fresh air inlet on the
outside of the building should be at least ten feet
apart to avoid cross-contamination. The exhaust
outlet should not dump air into an enclosed space
or any other structure. The inlets and outlets
should be screened against insects and vermin
and shielded from the weather to prevent the
entry of rain or snow.

The fresh air inlet should be at least 10’ away from
chimneys, furnace and water heater exhausts, and
other sources of carbon monoxide, humidity or other
contamination. Do not locate the fresh air inlet where
vehicles may be serviced or left idling. Never locate the
fresh air inlet inside a structure.

WARNING

NOTE: To prevent the entry of rain through the outside air inlet duct, observe the following:

1. Velocity at face of inlet hood should not exceed 500 feet per minute (fpm).

2. Inlet duct must be at least 18” x 18”.

3. Centerline length along duct from weather hood to unit inlet must be at least 48”.

4. Inlet duct must pitch downward to the outside; centerline of inlet hood must be at least 18” below
the centerline of the unit inlet.

5. Outlet duct must pitch downward to the outside with a slope of at least ¼” to the foot.

Ducts connecting the HE1.5X to the outside must be insulated, with sealed vapor barrier on both inside
and outside of the insulation. Insulate both the Outside Air (OA) and Exhaust Air (EA) ducts.

INSIDE DUCTWORK SYSTEM

Ensure Good Ductwork Design

Ductwork should be designed to allow the unit to
provide the required airflow and reduce pressure
drop for efficient, quiet operation. If the inside
ducts run through unconditioned spaces they must
be insulated with a sealed vapor barrier on both
inside and outside of insulation.

Use Non-motorized Dampers to Set and
Balance Air

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
HE1.5X Unit. See unit specification sheet for CFM /
ESP curves.

PLANNING

YOUR INSTALLATION

WARNING

RISK OF FIRE, ELECTRIC SHOCK, OR INJURY. OBSERVE ALL CODES AND THE FOLLOWING:

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 disconnect 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 licens­ing requirements.

4. Any structural alterations necessary for instal­lation must comply with all applicable building,
health, and safety code requirements.

5. This unit must be grounded.

6. Sufficient air is needed for proper combus­tion and exhausting of gases through the flue
(chimney) of fuel burning equipment that might be

installed in the area affected by this equipment.
If this unit is exhausting air from a space in
which chimney-vented fuel burning equipment is
located, take steps to assure that combustion
air supply is not affected. Follow the heating
equipment manufacturer’s requirements and the
combustion air supply requirements of applica­ble codes and standards.

7. Use the unit only in the manner intended by the
manufacturer. If you have questions, contact the
manufacturer.

8. 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.

9. When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities.

10. If installed indoors this unit must be properly

ducted to the outdoors.

SOUND ATTENUATION

CAUTION

To avoid motor bearing damage
and noisy and/or unbalanced
blowers, keep drywall spray,
construction dust, etc., out of unit.

Take these simple steps to attenuate noise from the unit.

OUTSIDE THE BUILDING

Exhaust velocity noise is the primary cause of
unit-related noise outside the building. Size the
exhaust duct and grille for less than 1000 FPM
air velocity. When practical, orient the exhaust air
hood to point away from houses or public areas.

DUCTS

Make sure the ductwork at the unit outlets is
stiff enough to resist the flexure and resulting
booming associated with system start-up and
shut-off.

In general, provide smooth transitions from the
ERV’s outlets to the duct. The ducts connecting
to the outlets should be straight for a sufficient
distance, with gradual transitions to the final
duct size.

These guidelines are consistent with SMACNA
recommended duct layout practices for efficient
and quiet air movement. Follow SMACNA guidelines.

RADIATED NOISE

The HE1.5XIN is insulated with high-density
fiberglass. This provides significant attenuation
of radiated sound.

The inlet ducts can be significant sources of
radiated sound as well. The OA and RA ducts
(inlet ducts) should be insulated for sound
control. This insulation should start at the unit.
At a minimum the first ten feet of duct should be
insulated. All parts of the OA and RA ducts located
in the mechanical space should be insulated for
sound control, both to minimize sound radiation
out of these ducts and also to control sound
radiation into the ducts.

INSTALLATION

FIELD CONVERSION OF OPENINGS

The HE1.5XIN is designed to allow field conversion
of the unit openings. This means the motorized im­peller subassemblies can be moved to an adjacent
wall of the unit if that opening is preferred. The
outlet openings can also be moved to an adjacent
wall. Before you start, plan the duct work layout.
Determine which openings are to be converted.

TO FIELD CONVERT INLET OPENING

1. Disconnect motor harness connector (A) by the
motor. Move the wire harness out of the way if
necessary.

2. Support the impeller subassembly. Remove the eight
¼-20 bolts (B) retaining the impeller subassembly
plate to the side rails and front and back tabs.

3. Lift the entire impeller subassembly (C) out of the
unit and set aside. Leave the rails in the unit.

4. Remove the patch pan (D) from the desired opening.

5. Using the exposed sheet metal cutout, cut the
insulation from the desired opening.

6. Seal the edges of the cut insulation to prevent
erosion of the insulation edges and having debris in
the air stream.

7. Install the patch pan over the undesired opening.

8. Install the insulation in the undesired opening. Seal
the insulation.

9. Remove the duct flange from the undesired opening
and install it at the desired opening.

10. If both inlet openings are to be converted, repeat

Steps 2 – 9 for the second inlet opening.

11. At this point, if there are outlet openings for

conversion, you will want to address them before
proceeding with the inlet opening.

12. After converting the outlet openings move the unit

floor brackets (E), if necessary, so when the unit
is re-oriented the floor brackets support the unit
on the floor.

13. Rotate the unit to the desired orientation, if necessary.

14. Install the impeller subassembly into the new inlet

opening and fasten with eight ¼-20 bolts to retain
to the side rails and front and back tabs. Make
sure the motor harness connector is towards the
front of the unit.

15. Connect the motor harness.

16. Repeat Steps 14 – 15 for other impeller

LOW VOLTAGE CONTROL SYSTEM

This ERV is provided with a Class II 24VAC power
supply system that operates the unit’s contactor(s)
for HE1.5X. The ERV’s 24VAC Power Supply can

A built-in circuit-breaker prevents damage to the
transformer and other low-voltage components in
the event of a short-circuit or overload. In extreme

cases, the transformer itself is designed to fail safely.
also be used to power the externally-installed con­trols system: up to 8VA of power is available.

The unit’s power supply system includes isolation
relay(s) so you can use external controls whose
contact ratings are as low as 50mA (1.2VA). Also,
it is possible to operate the isolation relays with
24VAC power from an external source (with proper

wiring connections).

CAUTION

1. Connect only to components intended for use with 24VAC power.

2. Do not undersize the low-voltage wires connected to this device. Observe the wire length and gauge

limits indicated in this manual.

3. Do not overload this unit’s 24VAC power supply system. Confirm that the power requirements of devices

you connect to this power supply system do not exceed 8VA in total.

4. If an external source of 24VAC power is used to control the unit, consult the wiring schematics and

connect the external power only to the specified terminals in order to avoid damaging the unit or external
controls. Connect only CLASS II power to the control terminals of this unit.

5. Unit is not equipped to receive analog signals (such as 1-10vdc or 4-20mA).

6. Unit is not equipped to communicate directly with Building Management Systems (such as BACNET,

LONWORKS, etc.). However, the unit can be controlled by powered or non-powered contacts operated by
any kind of control system.

INSTALLATION INSTRUCTION

CAUTION

If primary-side voltage is 230VAC,
move black primary-side lead from
transformer’s “208V” terminal to
the transformer’s terminal marked
“240V” (“230V” in some units).
Do not move the black primary­side lead that is connected to the
transformer’s “COM” terminal.

HOW TO RESET THE 24VAC CIRCUIT BREAKER

If the transformer is subjected to an excessive load or a short circuit, the circuit breaker will trip to prevent
the failure of the transformer. When it trips the circuit breaker’s button pops up. Shut off the primary-side
power to the unit, and remove the excessive load or the short. The circuit breaker can be reset about
fifteen seconds after it trips by pressing in the button.

LIMITS OF POWER OUTPUT

If limits on wire gauge and length are observed, you may connect control devices that draw up to 8VA to
the blue and red wires. More than one device can be connected as long as total steady-state load does
not exceed 8VA.

OBSERVE THESE LIMITS TO WIRE LENGTH AND GAUGE
in order to ensure reliable operation of the control system.

F. Control System Operating Isolation Dampers with End Switches: Use Isolation Dampers with elec-

trically separate end switches. The end switches are used to separately control the ERV unit’s Isolation
Relays. Also, specify the ERV with Independent Blower Control. This ensures that each damper is open
before the respective blower starts up.

NOTE: Because the ERV’s contactors will only be operating once the Dampers are open, the power

draw of the Damper Actuators is allowed to be as much as 35VA while opening (including power draw
of the external control system, if any). However the power draw of the fully-opened (stalled) Actuators
(and external control system if any) must be less than 8VA.

MAINTENANCE

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.

Keep your ERV performing at its best by cleaning it as described below:

TO CLEAN THE ENERGY EXCHANGE ELEMENT

Vacuum the face of the energy exchange element yearly. Dust collects only on the entering face of the energy
exchange element, right where the filter sits. The interior of the energy exchange element stays clean even if
the element faces are dust covered.

1. Remove the filters (see below)

2. Vacuum the exposed faces of the energy exchange element with a soft brush attachment

3. Vacuum out dust from the rest of the unit case

4. Install new filters

INSPECT AND CHANGE THE FILTERS REGULARLY.

Inspect and/or replace filters every two or three months when the HE1.5X is in regular use, or as need­ed. Filters must be used or the energy exchange core will become blocked by dust and the unit will not do its
job. In extreme cases components may be damaged.

1. To access the filters unlatch the access doors. The access doors may be removed.

2. Pull the dirty filters out and replace with new filters.

NOTE: The filters supplied in the unit are usually able to keep the energy exchange core clear for several

months. Finer filters can be used but must be cleaned more often. If using finer filters, their increased
resistance to flow must be allowed for in the system design.

MOTOR MAINTENANCE

The motor needs no lubrication. If necessary vacuum clean the blower wheels at the same time you
clean the face of the energy exchange element (annually).

REQUIREMENTS

CAUTION

DO NOT WASH THE ENERGY

EXCHANGE CORE.

Keep it away from water or fire to
avoid damaging it. Always handle
the core carefully.

WARNING

Don’t allow the access door to drop
when unlatched. Injury to personnel
or damage to unit may occur.

Keep fingers away from
between the access doors when
unlatching and opening the
doors. Potential PINCH POINT.

RISK OF INJURY OR DAMAGE.
Motor has an automatic reset thermal protector. Disconnect power before servicing or resetting motor thermal
protector. Use caution, motor may be hot. The motor must cool before it resets 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).
