INSTALLATION
PLACEMENT OF THE TRC500
The TRC500 is designed for installation indoors. Select a location that is central to the inside duct runs,
and close to both the exhaust duct (to the outside) and the fresh air duct (from the outside). The unit can
be installed in any orientation but the contractor is responsible for safe installation of the unit.
For maximum air performance minimize the number of elbows, and do not place elbows within three feet
of the TRC500’s discharges. For applications where duct noise is a critical issue, use noise attenuating
techniques such as duct isolation, insulation, and proper duct design per SMACNA or ASHRAE standards.
Provide Adequate Service Access
for Maintenance. The TRC500 will
require regular filter and core
inspections. Install the TRC500
where you can remove the
doors for cleaning the core and
replacing the filters, and where
you can get at the wiring for
installation and service.

APPLICATIONS
See figure F2 for examples of some common installation approaches.
F2Common Installation Approaches
Do not vent exhaust duct up through roof. Condensate will form in cold weather and run back into unit.
Instead, slope duct slightly downhill to a horizontal-discharge wall cap, which will allow any condensate to
drain to the outside.
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 12” inside diameter
3. centerline length along duct from weather hood to unit inlet must be at least 48”
4. 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
CAUTION
Tape both inner and outer vapor
barriers of insulated duct to collars
on duct adapters and on wall caps.
This is critical to prevent migration
of moisture into insulation. Build-
up of moisture can result in failure
of the duct system and/or frost
in the insulation. Make sure any
tears in the inner and outer vapor
barriers are sealed.
CAUTION
DUCTS TO THE OUTSIDE
The TRC500 requires four ducts:
- Exhaust Air Duct
(insulated duct from unit to outside);
- Outside Air Duct
(insulated duct from outside to unit);
- Room Air Duct (from room to unit);
- Fresh Air Duct (from unit to room).
Ducts from unit to the outside must be insulated
with sealed vapor barrier on both inside and
outside of the insulation or with closed-cell foam
insulation.
(4) 8” x12” duct flanges come standard with the
TRC500 unit. They are shipped loose in the box
and can be installed with screws provided. Holes
are provided on the inlet and outlet side of the unit.
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.
USING FLEX DUCT TO CONNECT
TRC500 TO OUTSIDE
Duct need not be flexible, but must have
continuous vapor barrier on both inner and outer
face of insulation. Position the duct adapters over
the openings. Install them with supplied self-
drilling screws.
Keep insulated duct runs as short and direct
as possible. Suspend or support duct per
manufacturer’s instructions.

YOUR INSTALLATION
INSTALLATION
INSIDE DUCTWORK SYSTEM
Use standard (shipped in box) 8” X 12” duct flange
to connect 8” X 12” duct to Room Air and Fresh Air
Ports on unit. Position duct flanges over openings.
Install with supplied screws.
Or fabricate equivalent, by forming a flange on the
first duct section and screw it to the TRC500. Make
sure appropriate duct sealant or tape is used to
provide an air tight seal.
NOTE: If the inside ducts run through un-conditioned
spaces they must be insulated with a sealed vapor
barrier on both inside and outside of insulation. In a
heated space, uninsulated duct is acceptable, but
insulated duct resists break out noise better. Duct
sealing improves ventilation performance.
Most installations will not require complicated duct
systems to provide good ventilation performance. If
ventilating several spaces, evaluate whether the air in
the spaces is regularly mixed by the heating/cooling
system; if not, provide a room air pick-up and fresh
air supply in each space. If air is regularly mixed by
the heating/cooling system, one room air pick-up and
one fresh air supply may be all that is needed.
Connecting to an existing air-circulation system
It is often convenient and effective to connect the
Fresh Air duct from the TRC500 to a return duct
of an existing heating/cooling system. This way,
whenever the heating/cooling system is running,
fresh air from the TRC500 is distributed throughout
the area served by the heating/cooling system.
Connect the Fresh Air duct to a branch return
duct at some distance from the heating/cooling
system’s air handler. This minimizes the amount of
air that the air handler can pull through the TRC500
when outside air ventilation is not desired.
If the TRC500 is running when the main air handler
is not, fresh air will flow into the space through the
branch’s return grille. Choose the return branch for
your connection accordingly (see next paragraph).
Ducting Fresh Air Directly into Space
In cold or hot weather, the fresh air will be
somewhat cooler or warmer than the room air
(though always much closer to room temperature
than the outside air!). Avoid complaints by locating
the Fresh Air supplies where they will not blow
directly on occupants.
See Figure F2 for examples of some common
installation approaches.

INSTALLATION
1. Before servicing or cleaning the unit, switch
power off at disconnect switch or service pan-
el and lock-out/tag-out to prevent power from
being switched on accidentally. More than one
disconnect switch may be required to de-ener-
gize 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 licens-
ing requirements.
4. Any structural alterations necessary for instal-
lation must comply with all applicable building,
health, and safety code requirements.
5. This unit must be grounded.
6. Sufficient air is needed for proper combus-
tion 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 applica-
ble 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. This unit must be properly ducted to the out-
doors.
RISK OF FIRE, ELECTRIC SHOCK, OR INJURY. OBSERVE ALL CODES AND THE FOLLOWING:
WARNING
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, as well
as the turbulent flow conditions at the blower outlets.
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 outlet ducts can be significant sources of
radiated sound as well. The FA and EA ducts (outlet
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 FA and EA 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.
AERODYNAMIC (VELOCITY) NOISE
When sound attenuation is a design concern, the
primary consideration is velocity noise at the unit’s
Fresh Air blower outlet. The average velocity at
the blower outlets is 1100 FPM when the unit is
operating at 600 CFM.

LOW VOLTAGE CONTROL SYSTEM
This ERV is provided with a Class II 24VAC power
supply system that operates the unit’s contactor for
TRC500. The ERV’s 24VAC Power Supply can also
be used to power the externally-installed controls
system: up to 8VA of power is available.
The unit’s power supply system includes an
isolation relay so you can use external controls
whose contact ratings are as low as 50mA (1.2VA).
Also, it is possible to operate the isolation relay with
24VAC power from an external source (with proper
wiring connections).
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.
SPECIFICATIONS
•Nominal Output Voltage under load: 24VAC
•Typical Output Voltage at no load: 29-31V
•Minimum contact rating for connected control

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.
CAUTION
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

WARNING
RISK OF INJURY OR DAMAGE.
Motor may have a manual reset thermal protector. Disconnect power before servicing or resetting motor ther-
mal 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
amperage 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.
Danger of injury from un-guarded blower in unit. Disconnect power to unit before opening door. Danger of
injury if unit starts unexpectedly. Switch power off at service disconnect. Lock-out/tag-out the disconnect.
WARNING
DO NOT WASH THE ENERGY
EXCHANGE CORE.
Keep it away from water or fire to
avoid damaging it. Always handle
the core carefully.
CAUTION
REQUIREMENTS
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 TRC500 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).
