2 EM MOTORS ABOUT RENEWAIRE For over 0 years, RenewAire has been a pioneer in enhancing indoor air quality (IAQ) in commercial and residential buildings of every size. This is achieved while maximizing sustainability through our fifthgeneration, static-plate, enthalpic-core Energy Recovery Ventilators (ERVs) that optimize 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 best warranty with the lowest claims due to long-term reliability derived from innovative design practices, expert workmanship and Quick Response Manufacturing (QRM). As the pioneer of static-plate core technology in North America, RenewAire is the largest ERV producer in the USA. We re committed to sustainable manufacturing and lessening our environmental footprint, and to that end our Madison, WI plant is 00% 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 00, RenewAire joined the Soler & Palau (S&P) Ventilation Group in order to provide direct access to the latest in energy-efficient air-moving technologies.

3 EM MOTORS PRODUT INFO EM MOTORS RenewAire s light commercial units are offered with optional electronically commutated motors (EM). EM motors have higher efficiencies with considerable energy savings over a standard permanent split capacitor motor. The EM motors offered in RenewAire 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 0-0Vdc analog signal. AUTION When an external 0VD source control is used the maximum distance between EM motor and 0VD source control cannot exceed feet (0m). ABOUT EM MOTORS OPERATING ONTROLS A wide variety of low voltage (VA) 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.

8 EM MOTORS INSTALLATION PLANNING YOUR INSTALLATION AUTION To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc., out of unit.. 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.. This installation manual shows the suggested installation method. Additional measures may be required by local codes and standards.. Installation work and electrical wiring must be done by qualified professional(s) in accordance with all applicable codes, standards and licensing requirements.. Any structural alterations necessary for installation must comply with all applicable building, health, and safety code requirements.. This unit must be grounded.. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment that might be installed in WARNING RISK OF FIRE, ELETRI SHOK, OR INJURY. OBSERVE ALL ODES AND THE FOLLOWING: the area affected by this equipment. If this unit is exhausting air from a space in which chimneyvented 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.. Use the unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.. 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. 0. If installed indoors this unit must be properly ducted to the outdoors. PRINIPLES OF EXTERNAL ONTROL The light commercial units with EM motors are designed for control by a wide variety of low voltage (VA) controls to meet the ventilation needs of the facility. These include time clock, occupancy sensor, carbon dioxide sensor, building management system (BMS) and others. These devices are commonly known as -wire, -wire, and -wire devices. RenewAire offers separately the following for standalone control of the ERV: Digital Time locks TD-W and TD-E Occupancy Sensors M- and M-W arbon Dioxide Sensor/ontrollers O-W and O-D HEX & HE.X ONLY The external control device connects to the Light ommercial unit to operate each blower independently or for one blower to act as leader and the other blower to act as follower. When operating independently, a single external switch or relay calls for operation but each speed control motor can respond independently to switch or analog signal source. When acting as leader-follower, again, a single external source calls for operation and then one motor responds to the input signal. The Light ommercial HEX & HE.X units have the versatility that either the exhaust air (EA) motor or the fresh air (FA) motor can act as leader. onnection of an external control device to the Light ommercial Unit is simple. All external control device wires connect to a terminal block(s) in the unit s electrical box. RENEWAIRE.OM EM MOTOR SUPPLEMENTAL MANUAL

13 EM MOTORS START-UP AIRFLOW PERFORMANE The ERV is factory wired to operate at low fixed speed and high 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. Figure translates the pressure drop across the energy recovery core to the actual airflow volume. AUTION Make sure clean filters are installed before balancing airflow. Dirty or clogged filters reduce airflow through the unit. AUTION Very low airflow rates may result in fouling of the energy exchanger core. Do not reduce airflow to below 0 cfm per core. AIRFLOW MEASURING AIRFLOW Equipment Required Magnehelic gauge or other device capable of measuring 0-. in. water of differential pressure. pieces of flexible tubing, / ID, / wall works best. NOTE: Be sure to remove cap from pressure port before inserting tubing. Insure tubing is well seated in pressure ports. NOTE: The tubing should extend in the pressure port approximately inch. ross ore Static Pressure Measurement Instructions The individual differential static pressures (DP) are measured using the installed pressure ports located in the front of the units core access doors. NOTE: These ports are carefully located on the unit to give the most accurate airflow measurement. NOTE: Do not relocate pressure ports. To read SFM 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 SFM 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 FM output using the conversion chart. NOTE: Be sure to replace cap into pressure port when air flow measuring is completed. Adjust air flow by changing the potentiometer setting for the measured airstream. NOTE: For best performance the airflow rate for both the Fresh Air and the Exhaust Air should be roughly equal ( balanced ). In some facilities a slight positive or negative pressure in the building is desired. RenewAire energy recovery ventilators can generally operate with a flow imbalance of up to 0% without significant loss in energy recovery efficiency EM EM MOTOR SUPPLEMENTAL MANUAL RENEWAIRE.OM
