OUTDOOR GRILLE SIZING

IMPORTANT: If you wish to use a grille not made

for the Gree E-TAC contact Gree Application

Engineering.

The following guidelines must be followed in the

initial selection of any altern ate exterior grille o r

louver:

1. The louver must haveaminimum of 65% free

area. Free area is the minimum area of the

opening in an air inlet or outlet in which air can

pass. Free Area (%) = X/Y.

2. The louver should be attached to the wall sleeve

in a manner that will prevent recirculation of

condenser di s charge air into the inlet. In most

applications, baffles, splitters, and/or gasket

will be required between the chassis tube end

sheets and the

louver to prevent air

recirculation.

The above criteria must be followed, since a louve r

that is res tric tive or allows re--circulation will result

in a reduction of the unit’s capacity and efficiency

and will ultimately shorten the compressor life.

NEW CONSTRUCTION

ADVANTAGES FOR NEW

CONSTRUCTION

Design Flexibility for the Architect/Engineer

• Whisper--quiet performance, indoors and out

• No bulky duct system

• No separate equipment room

• No water towers or additional cooling

equipment

• No complex match--up of different HVAC

components

• Less sensitivity to building orientation (sun,

wind, shade)

• Optional architectural grille to permit custom

exterior appearance

I nitial Cost Savings for the Buildin

g Owner

• No expensive compone

nt HVAC system

purchase

• No equipment room or maintenance

engineering staff

• Two--part delivery to minimize on--site

damage

• Weather--protected wall sleeve that goes in

place during construction; chassis that slides

in place after construction

• No seasonal changeover required for cooling

or heating -- units are self--contained comfort

systems

Lower Operating Costs and Reliable Comfort

for The Occupant

• Heat pump models offer substantial savings

over models with conventional electric

resistance heaters

• Individual units allow tenants to choose the

degree of comfort and operating economy.

• Rapid servicing reduces do

wntime: complete

chassis can be replaced in minutes without

disrupting other occupants.

• Each unit operates independently of other

units in the building. No dependency by

building on central HVAC system.

RETROFIT/REPLACEMENT

If you are replacing a unit in an existing wall sleeve,

your options include:

• Replace the existing wall sleeve with the

the polymer wall sleeve. See accessory sleeve

section for selecting the correct sleeve for

your application.

NOTE: in most cases, when replacing the

wall sleeve, the exterior grille must also be

replaced.

• Use an existing sleeve and exterior grille. The

Gree E-TAC will fit into:

—

— Friedrich T series and ZoneAire wall

sleeves, with a required wall sleeve

extension (see accessory Fr

iedrich

Retrofit Wall Sleeve Adapter).

E-TAC

Whether you are designing a new structure or

replacing packaged terminal air conditioning units in

an existing building, Gree E-TAC will meet your

needs.

The Gree E-TAC Packaged Terminal Air Conditioning

(E-TAC) unit is designed to meet the needs of the

architect, engineer, and contractor. For unit

installation, Gree’s expert support network will assist

in all applicable aspects of the construction project,

from preparing a budget to start-up.

The following major competitors’ wall

sleeves/grilles: Carrier, GE, Amana,

Trane, Friedrich and Bryant, and NO

accessory retrofit kit is required.
