SAFETY CONSIDERATIONS
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.
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.
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.
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. 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.
SIDE
Fig. 1 — Assembling the Roof Curb
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-CRB14MC 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.
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
