Only trained and qualified service personnel should install, repair, or service air-conditioning equipment. Untrained personnel can perform the basic maintenance functions of cleaning coils and filters and replacing filters. ll other operations should be performed by trained service personnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that may apply. Follow all safety codes. Wear safety glasses and work gloves. These instructions describe how to install, start up, and service 62M energy recovery ventilator units. Electrical shock can cause personal injury and death. Shut off all power to this equipment during installation. There may be more than one disconnect switch. Tag all disconnect locations to alert others not to restore power until work is completed. INTRODUCTION The 62M energy recovery ventilator (ERV) units recover energy from building exhaust air and pre-condition ventilation air. ll ERV units are available in either vertical discharge (through the bottom) or horizontal discharge configuration. The 62MB and MC vertical discharge units are used when a stand-alone ERV unit is required. The 62MD and ME horizontal discharge unit can be used as a stand-alone unit, or can also be coupled with a Carrier rooftop unit. INSTLLTION Step 1 Inspection Inspect the unit; file a claim with the shipping company if the unit is damaged. Check the packing list to ensure that the correct items have been received and notify your Carrier representative of any discrepancy. Step 2 Install Roof Curb STND-LONE PPLICTIONS The ERV unit can be installed without being coupled with a Carrier rooftop unit. The ERV units can be installed in one of three stand-alone applications: down discharge, horizontal discharge, or a combination of both down discharge and horizontal discharge. When installing a stand-alone ERV unit refer to Fig and, complete the following: Locate the Roof Curb Prior to locating the roof curb consider the structural support required for the rooftop system and, the duct drop location in relation to the joists. llow sufficient space for service, clearance, and locations of vents or other sources of air. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. Book 1 4 Catalog No Printed in U.S..

2 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. ssemble 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. Ensure the curb pieces are locked together prior to proceeding. Repeat for all corners of the roof curb. Prepare Roof Curb Location Cut a hole in the roof for duct openings. See Fig. 2-5 for duct opening dimensions. Frame the opening to provide adequate structural support. Install Deck Pans and Duct Supports The roof curb may have a duct support and deck pans, depending on the model and application. Determine which end of the roof curb will be the duct end. Install the deck pans on the roof curb with the insulation side facing up toward the ERV base. Install the duct support between the supply and return openings. 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. Cover the roof curb if installation of the ERV unit will not be immediate. Failure to cover the roof curb could result in water damage and/or serious personal injury. Install Ductwork Ductwork will be installed in the roof curb for vertical discharge and stand-alone applications. The duct will hang from the top of the curb. See Fig. 45 for standalone application airflow. NOTE: Ductwork must be installed before the ERV unit is set in place. Refer to Fig. 2-5 to determine the duct size required. Provide field manufactured duct and place into the supply and return openings in the curb. Install Gaskets The ERV roof curbs come with a gasketing package to provide a seal between the ERV unit and the top perimeter of the roof curb. Install the gasket around the top perimeter of the curb and around the supply and return opening. NOTE: Some stand-alone curbs will not have duct openings). Gasket strips must fit tightly together, leaving no gaps for leakage. IMPORTNT: Gasket installation is critical for water integrity. Improperly installed gaskets can result in air or water leaks, leading to poor unit performance. Install Roofing Materials Insulate and add a cant strip to the roof curb. Follow suggested and acceptable roofing practices END Fig. 1 ssembling the Roof Curb SIDE for applying roofing materials. The roofing material should extend up to the wood nailer and be secured under the counterflashing. Follow all local, national, and industry roofing standards. Refer to Fig. 6 for roofing recommendations. COUPLED PPLICTIONS The ERV unit can be installed directly coupled to a Carrier rooftop unit. The connection between the ERV and HVC (Heating, Ventilation, and ir Conditioning) unit is made with the use of a transition. In a coupled rooftop application there is a separate roof curb for the HVC curb and a separate roof curb for the ERV unit. See Fig. 4 and 5 for roof curb dimensions. Locate the Roof Curb Prior to locating the roof curb consider the structural support required for the rooftop system and, the duct drop location in relation to the joists. llow sufficient space for service, clearance, and locations of vents or other sources of air. Refer to the rooftop installation instructions for more information regarding location considerations. ssemble the Roof Curb Connect the curb side and the curb end. Insert the tabs on the curb end into the slots on the curb sides. Press firmly until the pieces lock in to place. It may be necessary to exert additional force to the top of the curb to lock the pieces in place. Ensure the curb pieces are locked together prior to proceeding. Repeat for other corners of the roof curb. NOTE: If lifting or moving the roof curb assembly hammer the tabs over 90 degrees. Install Deck Pans and Duct Supports The roof curb may have a duct support and deck pans, depending on the model and application. Refer to Fig Determine which end of the roof curb will be the duct end. Install the deck pans on the roof curb with the insulation side facing up toward the ERV base. Install the duct support between the supply and return openings. Install Locator Pieces Some ERV roof curbs (62M-CRB- 14MC and 62MB-CRB-14MC) will include locator pieces, which are to be attached to the ERV roof curb section. The locator pieces will help the installer ensure that the ERV and HVC unit roof curbs are positioned properly. ttach the 2 side locator pieces to the ERV roof curb. Install the cover panel over the 2 sides and fasten in place. 2

3 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. IMPORTNT: The ERV roof curb must be set in precisely the correct location relative to the rooftop roof curb for the transitions to connect properly. See Fig for location dimensions. Install Ductwork Ductwork will be installed in the roof curb for vertical, coupled applications. The duct will hang from the top of the curb. NOTE: Ductwork must be installed before the rooftop unit is set in place. NOTE: Ductwork must be installed before the ERV unit is set in place. 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. Install Gaskets The ERV roof curbs come with a gasketing package to provide a seal between the ERV unit and the top perimeter of the roof curb. Install the gasket around the top perimeter of the curb and around the supply and return opening. (Some stand-alone curbs will not have duct openings.) Gasket strips must fit tightly together, leaving no gaps for leakage. IMPORTNT: Gasket installation is critical for water integrity. Improperly installed gaskets can result in air or water leaks, leading to poor unit performance. Install Roofing Materials Insulate and add a cant strip to the roof curb.

47 Step 4 Installing ERV Transitions When coupling ERV units with Carrier rooftop units an ERV transition is required to link the ERV unit and the Carrier rooftop unit together. ERV UNIT COUPLED WITH 3 to 12 1 / 2 TON HVC UNIT Complete the following steps to install a transition to a3to12 1 / 2 ton rooftop unit. 1. Remove the HVC unit filter door and set aside for later use. 2. Remove the panel shipped on the HVC unit covering the return air chamber. This panel can be discarded. 3. The 62M ERV transition for 3 to 12 1 / 2 ton rooftop units includes a replacement panel to cover the return opening. Install the replacement panel, with hood scoop attached, onto the HVC unit, over the return air chamber. Screw in place. The return/exhaust scoop will cover part of the return air opening in the HVC unit. NOTE: The standard transition does not seal tight around the return air opening on the HVC unit. This allows for some air to flow back to the HVC unit and some to be drawn back through the ERV unit. 4. Slide the transition between the ERV unit and the HVC unit. Refer to Fig to orient the transition. Line up the transition so that it covers the openings in the HVC unit and the ERV unit. The divider in the transition must separate the supply and return openings in the ERV unit. Screw the mating flanges of the transition to the ERV unit through pre-punched holes. Caulk the seams watertight. Screw the mating flanges on the other side of the transition to the new return air cover panel on the HVC unit. Caulk seams watertight. 5. On most models the filter access door shipped with the HVC unit will be reinstalled above the transition. 6. The transition includes a balancing damper to allow for the desired separation of the return/exhaust air between the ERV and HVC units. This damper has a manual adjustment. During balancing, this damper will be adjusted to achieve desired exhaust cfm. The balancing damper can be accessed through a separate door in the transition or through the HVC unit s filter access door. See Fig Step 5 Make Electrical Connections Prior to performing service or maintenance operations on the ERV unit, turn off and disconnect all power switches to the unit. Be aware that there may be more than one disconnect switch. Electrical shock could cause serious personal injury or death. IMPORTNT: Only trained, qualified installers and service technicians should install, wire, start-up and service equipment. POWER SUPPLY The electrical characteristics of the available power supply must agree with the unit nameplate rating. Supply voltage must be within the limits shown. See Tables 2 and 3 for electrical and configuration data. ELECTRICL CONNECTIONS The ERV unit must have its own electrical disconnect box. If the disconnect option has not been ordered from the factory, it must be field supplied and installed per local codes. See Tables 2 and 3. If the ERV unit has an electric pre-heater factory installed, it will be wired through the ERV unit disconnect. NOTE: Most ERV units have electrical interlock safety switches on the access doors, which will not allow the ERV unit to operate if either of the access doors are opened. Low Voltage Wiring Wire low voltage per diagrams. For coupled applications, there will be a brown and black wire in the exhaust chamber, which must be tied into the HVC unit s indoor fan so that when the indoor fan is activated, the ERV unit will be activated. 48/50TJ, HJ 3 to 12 1 / 2 Ton Rooftop s with Economizers The brown and black wires can be plugged into the economizer jumper plug on the HVC unit s economizer harness. Insert the brown wire from the ERV unit into terminal 4 in the jumper plug and insert the black wire from the ERV unit into terminal 3 in the jumper plug. See Fig. 47. If the 3 to 12 1 / 2 ton rooftop unit has an economizer installed, the economizer will have an end switch attached to the economizer actuator. The end switch must be wired into the ERV unit as shown in Fig. 48. For ERV units coupled with units with factory-installed economizers, (48/50TM, HJ 15 to 25 ton units 48/50HG, PG 15 to 25 ton units) the ERV transitions to these rooftop units include an economizer end switch. This switch mounts to the hub of the economizer damper gear as shown in Fig. 49. Set the end switch so that the ERV unit s outside air blower is deactivated during economizer mode. For stand-alone units, the ERV unit is jumpered from terminals 6 and 8 and 7 and 9, providing for continuous operation. The ERV unit should be connected to an on-off device such as aco 2 sensor. High Voltage Wiring (Fig ) Connect high voltage wiring to the disconnect per Fig. 50, 52 and 53. Check blower rotation direction and adjust if necessary. 47
