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).
