Cover roof opening if installation of the ERV unit will not be immediate. Failure to cover roof opening could result in water damage and/or serious personal injury. END Assemble the Roof Curb — Connect the curb side and the curb end. See Fig. 1. Insert the tabs on the curb end into the slots on the curb sides. Press firmly until the pieces lock into place. It may be necessary to exert additional force to the top of the curb to lock the pieces in place.
Set the Roof Curb — Fit the roof curb assembly by measuring across the corners of the curb to ensure a square fit. Set the roof curb over the roof opening. Level the curb by placing shims under the bottom flange of the curb. Secure the curb in place by welding or fastening the curb to the roof. Refer to Fig. 2 and 3 to determine the duct size required. Provide field manufactured duct and place into the supply and return openings in the curb.

START-UP To achieve the highest level of effectiveness, the airflow across the supply and return should be equal. FACTORY SETTING — The ERV unit is factory set to achieve the maximum airflow cfm within the cabinet’s range. For example, a 62M170 unit has a range of 1,400 to 2,000 cfm airflow, and when shipped will be setup to achieve the 2,000 cfm airflow level. See Fig. 57-80. CURVE SELECTION — Refer to the fan curve for the ERV unit being used for the application. See Fig. 57-80.

Occupied Mode, with CO2 Sensor — When the CO2 sensor is used, it will measure the space CO2 levels in parts per million (ppm). The 62M ERV CO2 setting is factory set at 1,000 ppm but can be adjusted from 0 ppm to 2,000 ppm.
• • • EXH blower motor is turned on. The two-position damper is open (if used). The stop/jog option will periodically rotate the ERV wheel to clean it during wheel bypass operation. This feature is factory set to activate every 10 minutes, for 20 seconds of operation. Both settings can be adjusted from 0 to 10 minutes.
Removing and Installing Non-Segmented Wheel for Cleaning (62M075, 120 Units) — Non-segmented energy transfer wheels include the shaft and are secured to two wheel support beams by two flange bearings with locking collars. See Fig. 85. To remove the energy transfer wheel follow Steps 1-4 below. Reverse procedure for wheel installation. 1. Pull the wheel with shaft straight out of the motor side wheel support beam and bearing. Handle wheel with care to prevent distorting of the wheel. 2.
2. Using hexagonal wrench, loosen setscrew in bearing locking collar. Using light hammer and drift (in drift pin hole) tap collar in the direction of wheel rotation to unlock collar. Remove collar. 3. Using socket wrench with extension, remove two nuts which secure bearing housing to the bearing support beam. Slide bearing from shaft. NOTE: Slight hand pressure against wheel rim will lift weight of wheel from inner race of bearing to assist bearing removal and installation.

Wheel Drive Components — The wheel drive motor bearings are pre-lubricated and no further lubrication is necessary. Make certain air cooling ports are not blocked. The wheel drive a pulley is secured to the drive motor shaft by a setscrew. The setscrew is secured with removable adhesive to prevent loosening. Annually confirm setscrew is secure. The wheel drive belt is a urethane stretch belt designed to provide constant tension through the life of the belt. No adjustment is required.
