1.0 OVERVIEW
1.1 DESCRIPTION
The TRCeN-Series Energy Recovery Ventilator (ERV) is a device for recovering both sensible energy
(heat) and latent energy (moisture) from the Exhaust Air from an Occupied Space and injecting those
energies into an incoming Outside Air stream. It accomplishes this task by forcing the two airstreams
through enthalpic cores, where the energy exchange takes place. The two airstreams pass through
the enthalpic cores at right angles and the airstreams never mix together. See Section 2.2 Enthalpic
Cores in this manual.
Each ERV has two electric impellers, one for each airstream. Impellers have electronically
commutated motors controlled by a printed circuit board or by a BMS. There are a number of
different control devices available to control the operation or speed of the unit fans. For further
information on available control accessories, see the available supplemental installation and
operation manuals.
These ERVs are commonly installed as part of an air-handling system that provides heating and
cooling of Supply Air. They can also be installed to operate as stand-alone devices when ducted
directly to and from the Occupied Space.
Each unit has an integral 24VAC power supply that is used internally and can also be used as a
power source for other optional control devices.
The TRCeN-Series units are low-maintenance, requiring periodic replacement of the air filters
and annual vacuuming of the enthalpic cores. See Section 7.0 Unit Maintenance in this manual.
IMPORTANT
It is important to understand and use the equipment airstream terminology as it is used in
this manual. The airstreams are defined as:
uOUTSIDE AIR (OA): Air taken from the external atmosphere and, therefore, not previously
circulated through the system.
uSUPPLY AIR (SA): Air that is downstream of the enthalpic cores and is ready for condition-
ing or for return to the Occupied Space.
uRETURN AIR (RA): Air that is returned to the ERV from a conditioned space.
uEXHAUST AIR (EA): Air that is removed from a heating or cooling appliance or from the
Occupied Space and discharged.

COMPONENT DESCRIPTIONS
2.0 COMPONENT DESCRIPTIONS
2.1 CABINET
The cabinet for the TRCeN-Series is made of 20 gauge galvanized steel and has 1" thick high-
density, foil-backed insulation on the inside. Units are available in either single-wall or double-
wall construction. Doors are hinged and are fitted with stainless steel machine screws through
the faces to prevent accidental opening of the doors when the unit is in operation. Doors may be
completely removed by removing the hinge pins. Duct flanges are available as an accessory for
all airstream openings for connection of field-supplied ductwork.
2.2 ENTHALPIC CORES
All TRCeN-Series ERVs use a static-plate enthalpic core. The enthalpic cores transfer both
latent and sensible energies between the airstreams. Gasketing is pre-installed on the cores
and must be positioned to provide a proper air seal. For information on annual maintenance of
the cores, see Section 7.0 Maintenance in this manual.
2.3 IMPELLER/MOTOR ASSEMBLIES
Low airflow can cause
fouling of the enthalpic
cores. The ERV must
never be operated without
clean filters in place and
minimum airflow must be
greater than 250 CFM per
full-sized core.
CAUTION
There are two impeller and motor assemblies in each ERV.
2.4 E-BOX
Every TRCeN-Series ERV is equipped with what is known as an “E-Box.” High-voltage supply
wiring and low-voltage control wiring is all terminated here.

3.0 SHIPPING/RECEIVING/HANDLING
TRCeN-Series units are palletized at the factory and then shipped by common carrier. Upon
receipt by the installer, the shipment should be inspected for shipping damage, prior to
unloading. Any discovered shipping damage should be immediately reported to the Soler &
Palau sales rep and the damage must be recorded on the Bill Of Lading, prior to signing for
acceptance of the shipment. The unit can be handled with a fork lift or equipment hoist.
Prior to moving the unit, verify that all latches and securing bolts on the cabinet doors are
tightly fastened.
If an equipment hoist is used for moving a TRCeN-Series unit, unscrew the sheet metal plates
that hold the unit to the pallet. Use straps and a spreader bar to hoist the unit. The straps must
be spaced to ensure the unit is level and the center of gravity is positioned properly between
them. Unit hoisting weights and Center of Gravity are detailed in Sections 3.1 and 3.2 in this
manual.
Perform a test lift to make sure the unit is being hoisted level and is secure.
Place the TRCeN-Series unit on a flat surface where it will be protected from the weather and
incidental damage. Do not remove protective coverings from any duct openings and keep the
doors secured and tightly closed.

SHIPPING/RECEIVING
3.3 RECEIVING
Upon receipt of the TRCeN-Series, inspect the unit for obvious external damage. If damage is
observed, take digital pictures and report the damage to your Soler & Palau representative.
Note the damage on the carrier’s Bill of Lading. Depending on expected transport and storage
conditions, the unit may have only the duct openings covered, it may be stretch-wrapped or it
may be crated. Do not unwrap the unit at this time. The unit will normally be moved to its final
location while still wrapped and attached to its pallet.
The preferred method of hoisting the TRCeN-Series from the carrier truck is by using a
construction forklift or a crane.
Once the unit is unwrapped, prevent dirt and debris from entering the cabinet by covering any
duct openings that do not have attached dampers. Keep the duct openings covered until it’s
time to connect ductwork.

4.0 UNIT PLACEMENT
4.1 BEFORE YOU BEGIN
The TRCeN-Series ERV is designed for installation in a sheltered location, out of the weather.
The preferred mounting location is to place the unit on a concrete floor, although it can also be
suspended from a ceiling or other structural support. See Section 5.3, Suspended Mount, in
this manual.
For all installations, maintain needed service clearances as shown on the dimensioned drawings
located in Section 4.2 of this manual.
For all floor-mount installations, the unit should be set on its factory-provided adjustable legs
and leveled. Select a location that is central to the inside duct runs and close to both the
exhaust duct (to the outside) and also to the OA duct (from the outside).
The EA outlet and the OA inlet on the outside of the building should be at least 10' apart to
avoid cross-contamination. Comply with all local building codes in the positioning of the duct
openings. Do not position the EA outlet in a location where it will dump EA into any enclosed or
occupied space. The duct inlets and outlets should be screened against insects and vermin and
should be shielded from the weather to prevent entry of rain or snow.

4.3 SOUND ATTENUATION
Take these simple steps to attenuate noise from the unit.
4.3.1 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 impeller 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.
4.3.2 Radiated Noise
The TRCeN-Series ERV is insulated with Expanded Polystyrene (EPS) foam. This provides
significant attenuation of radiated sound from the unit itself.
The inlet ducts can be significant sources of radiated sound as well. The RA duct should be
insulated for sound control. This insulation should start at the unit. At a minimum the first 10' of
duct should be insulated. All parts of the SA and RA ducts located in a mechanical space with
noise-generating equipment also should be insulated for sound control, both to minimize sound
radiation out of the RA duct, and also to control sound radiation into both ducts.
4.3.3 Connecting Ducts to Unit
Flanged duct connections are available as an accessory for the duct connections of the
horizontal TRCeN-Series units. These allow for connection of ducts insulated on the inside or
the outside, or for installation of lined duct. Please refer to dimension drawings for duct
flange sizes.
5.0 INSTALLATION
5.1.1 Ducts to the Outside
The exhaust outlet and fresh air inlet on the outside of the building should be at least 10' 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.
Ducts connecting the TRCeN-Series to the outside must be insulated, with sealed vapor barrier
on both inside and outside of the insulation. Insulate both the OA and EA ducts.
5.1 DUCTWORK
Tape both inner and outer
vapor barriers of insulated
duct to collars on duct
adapters. 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
NOTE: Ducts inside
a building that are
connected to the
outside must be
insulated with a sealed
vapor barrier on both the
inside and the outside of
the insulation.
5.1.2 Inside Ductwork System
Follow Engineer’s Ductwork Design; ductwork should be designed by an engineer to allow the
unit to provide the required airflow.
5.1.4 Adjust Fan Speed to Set and Balance Airflow Rates
In most applications, the airflow rate for both the SA and the EA should be roughly equal (or
“balanced”) for best performance of the TRCeN-Series unit. See unit specification sheet for
CFM/ESP operating envelopes for available motors.
5.1.3 Duct Insulation
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.
INSTALLATION

TRCeN-Series
ERV
14 WWW.SOLERPALAU-USA.COM INSTALLATION, OPERATION AND MAINTENANCE MANUAL 1.800.961.7370
INSTALLATION
5.2 FLOOR INSTALLATION
Most units are installed in a location specified by others. In general, it’s preferable to install the
unit on a flat, reasonably level surface, such as a concrete floor. The factory-installed leveling
legs are to be used to level the unit before connecting ductwork. When positioning the unit, it is
not to be slid on its adjustable legs because they can be bent.
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 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 out-
side; 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.
5.3 SUSPENDED MOUNT
5.3.1 Hanging Unit From Structure
TRCeN-Series units can also be suspended from a ceiling or other structural member and may
be hung in any orientation. The preferred method of support is to remove the four adjustable
legs and bolt heavy-gauge Unistrut or other structural channels to the underside of the unit,
using the 3/8"-16 threaded holes where the adjustable legs were located. Install 3/8"-16 bolts
through the channels, into the bottom of the unit. Support the channels from threaded rods,
located in an appropriate location that maintains required service clearances.
5.3.2 Hanging Vibration Isolators
When suspending TRCeN-Series units from a ceiling or structure, it may be necessary to isolate
the unit from transmitting vibration to the structural members. Hanging Vibration Isolators are
available as an accessory for the TRCeN-Series. Use the corner weights
depicted in Figures 3.2.0 through 3.2.3 to select isolators with the proper load ratings. The
isolators are designed for use with 3/8" threaded rod. Attach the threaded rod to the support
rails for the unit as shown in Figure 5.3.0. For mounting details, see the isolator specification
sheets at the links below.

5.3.3 Hanging Bracket Kit
The TRCeN-Series ERV can also be mounted to structural members using the Hanging Bracket
Kit, available as an accessory. Remove the four adjustable legs and use the included 3/8"-16
bolts and washers to attach the hanging brackets to the unit as shown in Figure 5.3.1. The
hanging brackets may be attached directly to a structural member or used in combination with
threaded rod and the hanging vibration isolators described in section 5.3.2.
If the spacing of the unit mount points does not fit the application, the hanging brackets may
alternatively be attached directly to the cabinet using (16) #12 x 3/4" long self-tapping sheet
metal screws (not provided). Ensure that the unit is adequately supported at all four corners and
that the placement of the brackets maintains required service clearances.

5.4.1 Factory-Recommended Electric Service Entry
The TRCeN-Series has an internal E-box in the lower left corner of the unit. 7/8" knockouts
are provided on the sides and bottom of the unit for high-voltage power and low-voltage
control entry. Install the wiring in accordance with local codes and provide strain relief at the
E-box opening.
High-voltage supply wiring is to be connected on the top side of the disconnect switch. See
image below.
5.4.2 Low Voltage Control System
This ERV is provided with a Class II 24VAC power supply system that operates the unit’s EC
control board. 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 isolation relay(s) so you can use external controls
whose contact ratings are as low as 50 mA (1.2 VA). 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:
uNominal Output Voltage under load: 24VAC
uTypical Output Voltage at no load: 29–31 V

CAUTION
5.4.3 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.
If primary-side voltage
is 230VAC, move black
primary-side lead from
transformer’s “208V” ter-
minal to the transformer’s
terminal marked “240V”
(“230V” in some units).
Do not move the black
primary-side lead that is
connected to the trans-
former’s “COM” terminal.

TRCeN-Series
ERV
20 WWW.SOLERPALAU-USA.COM INSTALLATION, OPERATION AND MAINTENANCE MANUAL 1.800.961.7370
6.0 OPERATION
6.1 PRINCIPLE OF OPERATION
The TRCeN-Series ERV has one basic purpose: to exhaust air from a structure and bring in SA
from outside, while transferring heating or cooling energy from the EA to the SA.
The TRCeN-Series ERV is a very simple device, and will accomplish this purpose as long as the
impeller is able to move air through the enthalpic core.
6.2 PRE-START UP
6.2.1 Verify Voltages
Using a voltmeter, test the input voltages as supplied to the disconnect switch. Refer to the unit
nameplate label to find the rated voltage. The supplied voltage must be within +/- 10% of the
rated voltage.
6.2.2 Verify Transformer Wiring
Units with 230VAC power source are shipped with the transformer wired for 208VAC. If the unit
is receiving 230VAC, make sure the black primary-side wire on the transformer’s 208V terminal
has been moved to the 230V terminal.
6.2.3 Inspect Filters
Clean filters must be installed prior to fan start up.
6.2.4 Inspect Foam Gasketing
Inspect the gasketing to make sure there are no gaps allowing air movement around the cores
or filters.
6.2.5 Inspect Fans
Prior to start up, the fans should be rotated by hand to make sure that the impeller is not
rubbing anywhere and that they turn freely.
6.2.6 Inspect and Clean the Cabinet Interior
During the construction and installation phases of a project, dust, dirt and debris will often
accumulate inside a unit. Thoroughly clean the inside of the unit by vacuuming and/or wiping
metal surfaces with a damp rag.
6.2.7 Inspect Ductwork Connections
Ducts attached to the ERV must be firmly attached, sealed and supported in accordance with
installation instructions and SMACNA guidelines.
NOTE: The door
interlock switch
will prevent the
fans from turning on if the
access door on that side
is open.
6.3 UNIT START UP
6.3.1 Starting Up ECM Units
Units equipped with standard control do not require any external controlling signals and only
require turning on the disconnect switch, located on the E-Box or cabinet access door. When
the disconnect switch is turned “ON” a speed signal is supplied to the motorized impellers,
causing the fans to run.
Some units equipped with standard control are wired to receive an actuating signal from an
external source. If there is an external actuation signal source, verify the type of signal and that
it is wired according to the low-voltage wiring diagrams found in Section 5.5 of this manual.
Turn “ON” the disconnect switch and then turn “ON” the actuating device. A speed signal is
supplied to the motorized impellers, causing the fans to run.
