How It Works The PRO-C Series Energy Recovery Ventilator is an outdoor air preconditioner specifically designed to reduce the energy required to cool or heat the outdoor air by as much as 80 percent. The PRO-C also allows the Carrier® 3 through 121/2 ton HJ, TM and TF roof top air-conditioner systems to effectively and economically accommodate the three-to-four fold increase in outdoor air quantities, which is recommended by the ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality.
Model Description On the front of the PRO-C is an identification label (Figure 2). The specifications on the label correspond to the actual unit. The model number PROC-1000 refers to the nominal air volume (in cfm) that the PRO-C unit is capable of supplying. 8 Outdoor air – The fresh outside air that is being drawn in to the energy recovery wheel. Once it passes through the wheel it becomes the supply air. 9 Return air – Air from the indoor space that is pulled through the energy recovery wheel.
Receiving & Inspection Storage Upon delivery, confirm that the quantity and model(s) received matches the Bill of Lading. If there is any discrepancy, immediately notify ERV Systems. Inspect the skidded PRO-C(s) for signs of damage. If damage is suspected, sign the Bill of Lading “damaged.” If no visible damage is apparent, the unit should be properly lifted and stored until installation. While skidded, the PRO-C can be lifted by a forklift using the skid.
P ro-C S e r i e s Installation 4 Installation of the PRO-C unit is a relatively simple procedure, but should be undertaken in a methodical fashion, following the directions outlined in this manual. The installation location should be chosen to provide easy, convenient access. As with all mechanical equipment, routine maintenance and inspection is necessary. Avoid locations that are near or downwind of smoke, fumes or exhaust outlets of other equipment.
5. Install the PRO-C support angle to the base of the carrier unit. (9 screws) 9. Lower the roof of the carrier unit so that it covers the top edge of the PRO-C unit. Install a minimum 3 #12 Tek screws across the top flange of the Carrier unit. 3 Tek screws 6. Install the return air scoop to the return air opening of the PRO-C unit. 10. If included, place the pedestal support at end of the PRO-C unit, opposite the Carrier Unit. The pedestal support is adjustable from 9” to 14”. 11.
PRO-C-2400 Installation Instructions: 5. Install the PRO-C support angle to the base of the carrier unit. 1. Open the fan door of the PRO-C unit and remove all items (manuals & parts). 6. Install the right side angle trim to the Carrier unit and secure with screws. P ro-C S e r i e s 2. Remove protective plastic from the Supply Air and Return Air openings. 7. Install the bottom angle trim to the PRO-C unit. 3. Remove the screws from the roof of the Carrier unit. Lift roof and block. 4.
. Install the gasket to the left and right facing edges of the Carrier unit. Support The PRO-C unit is designed to support off the end of the Carrier unit. A required optional pedestal support is available from ERV Systems for the PRO-C series. The PRO-C series should not be installed without the pedestal support. (See Figure 5a.) This pedestal adjusts in height from 9 to 14 inches. 10. Bring the units together and set into place. Figure 5a.
Supply/Exhaust Airflow Dampers P ro-C S e r i e s All PRO-C units have airflow dampers on the outdoor air intake and exhaust air outlet that are field adjustable. To adjust the outside airflow damper, turn the unit off and open the access panel. Locate the outside airflow damper actuator inside the unit on the right side. Loosen the two end stops and with a No. 2 Phillips head screwdriver. Move the stops to the desired positions and retighten the screws.
Controls Basic Package The basic PRO-C unit ships with no controls. The standard wiring package provides connections for the starting/ stopping of the complete unit, supply fan and the energy wheel. The connections are shipped with factory jumpers installed. Remote control of any of these options can be achieved by removing the correct factory jumper and installing a contact in its place. The contact should be capable of handling 24V power at 2 amps (PRO-C-1000) or 3.5 amps (PRO-C-2400).
The stop/jog economizer option is used during moderate outdoor air temperatures to stop the recovery wheel. The jog function is included to allow the wheel to rotate periodically to self-clean. When the outdoor temperature is between 55°F (the cooling coil supply air temperature) and 75°F (the space return air temperature) the wheel will raise the outdoor air temperature which will add slightly to the space sensible load.

Wheel Cassette The wheel cassette can be serviced through the front panel. The cassette can be slid out for easy access. To remove the cassette, unplug the leads to the wheel drive motor, then remove the (2) tek screws located near the opening. This will then allow you to pull the cassette out of the unit through the access door. If the unit is equipped with a rotation sensor, it must be removed prior to sliding the cassette out.

Maintenance Filters – The PRO-C utilizes one-inch deep industrial grade aluminum mesh filters. The filters can be removed and washed. (See Figure 13.) We suggest that the filters be washed or replaced a minimum of once every four months. Replacement filters are readily available through ERV Systems, locally through HVAC supply distributors or McMaster-Carr. Seals – Surrounding the rim of the wheel is a brush seal. Do not tamper with this seal. No maintenance of the seal is required. Figure 12.
Belts How to Measure, Assemble and Install PowerTwist® Plus™ V-Belts PowerTwist® PlusTM V-Belts are supplied by Fenner Drives. For additional information about the company, please refer to the contact information on page 22. Measuring the Belt P ro-C S e r i e s Pull belt tight around sheaves to check hand tight length, overlapping the last two tabs with two holes in matching links as shown in Figure 15.
Installation 1. Turn belt with tabs to the inside before installing. 2. Determine direction of drive rotation. 3. Align belt directional arrow with drive rotation. 4. Fit belt in nearest groove of smaller sheave. 5. Roll belt onto larger sheave, turning the drive slowly. Belt may seem very tight; this is okay. DO NOT jog motor. 6. Check to see all tabs are still in their correct position and are not twisted out of alignment. Alternative Installation Method 1.
