WWW.SOLERPALAU-USA.COM INSTALLATION, OPERATION AND MAINTENANCE MANUAL 1.800.961.737066
PLACEMENT OF THE TRC800 & TRC800V
TheTRC800/TRC800V 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.
PLANNING
YOUR INSTALLATION
INSTALLATION
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 12” inside diameter.
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 unit 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 TRC Unit.
See unit specification sheet for CFM/ESP curves.
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.

RISK OF FIRE, ELECTRIC SHOCK, OR INJURY. OBSERVE ALL CODES AND THE FOLLOWING:
WARNING
INSTALLATION
PLANNING
YOUR INSTALLATION
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 TRC800/TRC800V is insulated with high-den-
sity
fiberglass. This provides significant attenuation
of radiated sound.
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 1235 FPM
when the unit is operating at 970 CFM.
SOUND ATTENUATION
To avoid motor bearing damage
and noisy and/or unbalanced
blowers, keep drywall spray,
construction dust, etc., out of unit.

INSTALLATION
INSTALLATION INSTRUCTIONSLOW VOLTAGE CONTROL SYSTEM
This ERV is provided with a Class II 24VAC power
supply system that operates the unit’s contactor(s)
for TRC800 & TRC800V. The ERV’s 24VAC Power
Supply can also be used to power the external-
ly-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).
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
device: (50mA (1.2VA)
•Circuit Breaker Trip Point: 3A
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.
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 exceed 8VA.
OBSERVE THESE LIMITS TO WIRE LENGTH AND GAUGE
in order to ensure reliable operation of the control system.
Wire Gauge #22 #20 #18 #16 #14 #12
Circuit Length 100’ 150’ 250’ 400’ 700’ 1000’
“Circuit Length” is distance from ERV to Control Device.
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).

unit schematics elsewhere in this manual.
CONTROL WIRING EXAMPLES BY TYPE OF APPLICATION
A. Single 2-wire Control: Use this schematic if the control requires no power to operate and acts like
a simple on/off switch. The control must not supply any power to the ERV unit. Connect the blue lead
to one yellow lead. Connect the control’s contacts to the red lead and the remaining yellow lead.
Control on separate Power Supply, no power present at Control Output:
Wire as shown for the Single 2-wire control.
C. Control operating on Unit’s 24VAC Power Supply: 24VAC power is available at the blue and red
leads. Connect one of the yellow leads to the blue lead. Connect the switched output of the Control
to the red lead to operate the ERV’s isolation relay.
B. Control Sending 24VAC “On” Signal (from an external power source) to ERV: Make sure the blue
and red leads are separately capped and not connected to any other wires. Now you safely can apply
24VAC to the two yellow leads to operate the ERV’s isolation relay.
Be careful if the external control system provides
24VAC power at its control output: make sure
blue and red leads are separately capped and not
connected to any other wires.

The individual differential static pressures (DSP)
can be measured using the installed pressure ports
located in the front of the units core access doors.
NOTE: These ports have been carefully located on
the unit as to give you the most accurate airflow
measurement. Do not relocate pressure ports.
•To read SCFM of Fresh Air (FA) install the “high”
pressure side (+) of your measuring device to the
Outside Air (OA) port and the “low” pressure side
(-) to the Fresh Air (FA) port.
•To read SCFM of Room Air (RA) install the “high”
pressure side (+) of your measuring device to the
Room Air (RA) port and the “low” pressure side
(-) to the Exhaust Air (EA) port.
•Use the reading displayed on your measurement
device to cross reference the CFM output using
the conversion chart.
NOTE: Be sure to replace cap into pressure port
when air flow measuring is completed.

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 TRC800/V 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 filter access door. The filter access door may be removed.
2. Remove filter keeper.
3. Pull the dirty filters out and replace with new filters.
4. Reinstall the filter keeper.
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).
Don’t allow the filter access door
to drop when unlatched. Injury
to personnel or damage to unit
may occur.
Keep fingers away from
between the filter access door
and the blower access panel
when unlatching and opening
the filter access door. Potential
PINCH POINT.
DO NOT WASH THE ENERGY
EXCHANGE CORE.
Keep it away from water or fire to
avoid damaging it. Always handle
the core carefully.
CAUTION
WARNING
RISK OF INJURY OR DAMAGE.
Motor may have a manual reset thermal protector. Disconnect 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
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 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.
