SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical components. 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. All 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. All 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.
INSTALLATION
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
STAND-ALONE APPLICATIONS — 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. 1-45 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. Allow 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.

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.
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. 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.
IMPORTANT: 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

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 APPLICATIONS — The ERV unit can be installed directly coupled to a Carrier rooftop unit. The connection between the ERV and HVAC (Heating, Ventilation, and Air Conditioning) unit is made with the use of a transition. In a coupled rooftop application there is a separate roof curb for the HVAC 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. Allow 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.
Assemble 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. 2-5. 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 (62MA-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 HVAC unit roof curbs are positioned properly. Attach the 2 side locator pieces to the ERV roof curb. Install the cover panel over the 2 sides and fasten 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.
IMPORTANT: 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. 7-44 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.
IMPORTANT: 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 procedures for applying roofing materials. The roofing material should extend up to the wood nailer and be secured under the counter flashing. Follow all local, national, and industry roofing standards. Refer to Fig. 5 for roofing recommendations.
