SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can

be hazardous due to system pressure and electrical compo-

nents. 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.

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 applica-

tions: 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 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.

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 discon-

nect locations to alert others not to restore power until work

is completed.

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.
