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.

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 stand-
alone 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.

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 counter-
flashing. Follow all local, national, and industry roofing
standards. Refer to Fig. 6 for roofing recommendations.
COUPLED APPLICATIONS — The ERV unit can be in-
stalled directly coupled to a Carrier rooftop unit. The connec-
tion 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 con-
sider 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 to-
gether 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.

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.

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.

IMPORTANT: Gasket installation is critical for water
integrity. Improperly installed gaskets can result in air
or water leaks, leading to poor unit performance.
