Part 1—System Description

Packaged Terminal Air Conditioners shall be of the

sizes and capacities as shown on the contract drawing

schedule and in the specifications.

System shall be tested to insure no water infiltration

into the room, when tested at eight inches of rain per

hour with 40 mph (64.4 KPh) wind.

The complete system shall consist of the following:

A. Packaged Terminal Heat Pump or Heat/Cool

Chassis : See section 2 -- Chassis Description

B. Power Cord or Hardwire Kit shall provide the

power connection to the unit.

C. Insulated Polymer Wall Sleeve shall provide

excellent thermal insulation, be textured to hide

scratches and prevent shine, will have superior

outdoor noise absorption and shall be corrosion

free for the life of the product. The Wall Sleeve

must have dimensions of 42” (1067 mm) width x

16“ (406 mm) height x 14--7/8” (377.8 mm) depth

and be shipped with a rear weather barrier

installed.

D. Wall Sleeve Molding shall trim the wall sleeve to

the existing wall to hide wall imperfections and

irregularities due to the sleeve opening.

E. Outdoor Polymer Louvered Grille shall resist

corrosion, breakage and match the color specified

on drawing schedule and specifications.

F. Subbase will support the wall sleeve when it

extends into the room more than 4“ (101.6 mm).

Subbase must come from the factory

pre-assembled, (size as specified on drawing

schedule and specifications).

Part 2—Chassis Description

2.1 General:

The chassis shall be a factory--assembled,

single--piece heating and/or cooling unit, that is

simple to install and operate. Just slide the chassis

into a wall sleeve, plug it into an outlet, and operate

after installation. The chassis dimensions sha

ll not

exceed 42” (1067 mm) wide and 16“ (406 mm) high

with room cabinet in place. The chassis shall consist

of the following functional sections and components:

A. Certifications:

System shall be approved and certified by UL &

UL, Canada. Chassis shall meet ASHRAE Standard

90.1 for minimum energy efficiency.

B. Operating Characteristics:

Chassis shall be capable of starting and running at

115˚ F (46.1˚ C) ambient outdoor temperature per

maximum load criteria of ARI Standard 310/380.

C. Electrical:

The power cord will be 58” (1473 mm) for 208/230v

models or 15“ (381 mm) for 265v models. The

Hardwire kit accessory will provide 36” (914 mm)

of flexible conduit. The chassis current draw shall

be specified on the chassis nameplate and match

electrical requirements specified on the Contract

drawing schedule and specifications.

The power cord plug configuration shall conform

to NEMA standards and the rating shall support

the current draw of the electric resistance heater.

For 265v installations, UL codes require the use of

an electrical equipped subbase for power cord

usage or hardwire conduit for non--corded

installations.

D. Safeties:

Compressor shall have automatic reset, over

temperature and over current protection. The fan

motors shall have an inherent, automatic reset

over temperature protection. The electric heate

shall have two over temperature protectors.

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 expe

nsive component 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 servic

ing reduces downtime: 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 accessor

y Friedrich

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.
