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 an 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.
CAUTION
When an external 10 VDC source control
is used, the maximum distance between
the EC Motor and 10 VDC source control
cannot exceed 33 ft (10 m).
CAUTION
To avoid motor bearing damage and noisy
and/or unbalanced impellers, keep drywall
spray, construction dust, etc., out of unit.
CAUTION
Very low airflow rates may result in fouling
of the energy exchanger core. Do not re-
duce airflow to below 250 cfm per core.
Make sure clean filters are installed before
balancing airflow. Dirty or clogged filters
reduce airflow through the unit.
CAUTION

1.0 OVERVIEW
S&P USA operations are based in Jacksonville, Florida. This geographically strategic location
allows the shipment of products throughout the U.S. and Canada. The Jacksonville
manufacturing facility has more than 150,000 square feet of warehouse space for the stocking
of a comprehensive range of products. This permits the overnight delivery of many popular
model sizes to anywhere in the U.S. and Canada.
At S&P USA we take pride in the fact that our customers receive only the very highest levels of
customer service and care. Our internal and external technical and customer service teams are
on-hand to provide professional and experienced application advice to enable our customers
to apply our products to their particular ventilation and air movement applications. As the USA
sales, marketing and distribution division of the S&P Group of companies we are committed to
providing only the very highest levels of customer service. Our commitment in providing only
the very highest standards of customer service is key to our company strategy.
S&P Ventilation Group is the world’s leading fan manufacturer. It celebrated its 50th anniversary
in 2001. S&P is able to offer a range of ventilation products benefiting from over 50 years of
experience in the industry. The company’s impressive, long-term growth is the result of one
simple philosophy - develop an air moving product that effectively and efficiently meets the
needs of the customer, supported by unparalleled engineering, distribution and service.
In 1951 Eduard and Josep Palau, both born in Ripoll, Spain, founded the company Soler & Palau
(S&P). From the very start the business proved to be their vocation. Together they combined
their extensive knowledge and flair to ensure the successful start of their business project.
There is continual in-house product development with state-of-the-art technology, and a
continued program of in-house laboratory certifications.
Currently S&P’s R&D, manufacturing and distribution facilities occupy a total of 1.1 million
square feet, with offices and locations around the globe. S&P products can be found in virtu-
ally any commercial or residential application, ranging from innovative, quiet and reliable room
ventilators to large diameter, high capacity exhaust systems designed for critical applications in
some of the world’s toughest environments.
1.1 DESCRIPTION
S&P’s light commercial units are offered with optional electronically commutated motors
(ECM). ECM motors have higher efficiencies with considerable energy savings over a standard
permanent split capacitor motor. The ECM motors offered in S&P ERVs are constant torque with
a variety of speed control options. The motors operate at fixed speed or variable speed with
speed inputs from fixed resistors, potentiometer, or 0-10Vdc analog signal.
1.2 OPERATING CONTROLS
A wide variety of low voltage (24 VAC) control schemes may be selected to meet the ventilation
needs of the facility. These include time clock, occupancy sensor, carbon dioxide sensor, and
others. Building Management Systems (BMS) may also control the unit with external control by
others.

4.0 OPERATION
4.1 AIRFLOW PERFORMANCE
The ERV is factory wired to operate at low fixed speed and variable speed.
Airflows must be measured and the unit’s potentiometers adjusted so that it operates at the
airflow volumes specified for the installation.
Use the pressure taps in the core and filter doors to determine the airflow. Section 4.3
translates the pressure drop across the energy recovery core to the actual airflow volume.
4.2 MEASURING AIRFLOW
4.2.1 Equipment Required
u
Magnehelic gauge or other device capable of measuring 0–1.5 in. water of
differential pressure.
u
2 pieces of flexible tubing, 1/8" ID, 1/16" wall works best.
4.2.2 Cross Core Static Pressure Measurement Instructions
u
The individual differential pressures (DP) are measured using the installed pressure ports
located in the front of the units core access doors.
u
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.
u
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.
u
Use the reading displayed on your measurement device to cross reference the CFM output
using the conversion chart.
u
Adjust airflow by changing the potentiometer setting for the measured airstream.
NOTE: Be sure to
remove cap from
pressure port before
inserting tubing. Ensure
tubing is well seated in
pressure ports.
NOTE: The tubing
should extend in
the pressure port
approximately 1".
NOTE: These ports
are carefully located
on the unit to give
the most accurate airflow
measurement. Do not
relocate ports.
NOTE: Be sure to
replace cap into
pressure port when
airflow measuring is
complete.
NOTE: For best
performance the
airflow rate for
both the FA and EA should
be roughly equal (“bal-
anced”). In some facil-
ities a slight positive or
negative pressure in the
building is desired. S&P
energy recovery ventilators
can generally operate with
a flow imbalance of up to
20% without significant
loss in energy recovery
efficiency.
