Economical operation

The duct-free split system design allows

individual room heating or cooling only

where required. There is no need to

run large supply-air fans or chilled

water pumps to handle a few spaces

with unique load patterns. In addition,

because air is moved only in the space

required, no energy is wasted moving

air through ducts.

Features like the rifled copper tube

with louvered aluminum plate fin coil

provide maximum heat transfer.

Lightweight, compact size

The small footprint of these units pro-

vides additional benefits. The exclusive

aero acoustics makes these units the

most compact in the industry. Because

they require minimal service and air-

flow clearances, condensing units can

be located virtually anywhere — on the

ground, roof, balcony, or under a deck.

The outdoor unit can be mounted

on any type or weight roof, and the in-

door units take up little valuable, rent-

able space. Because they are duct-free,

not having to run large ductwork

leaves additional space to be rented or

utilized, making the building even more

profitable.

In addition, the small size makes

these units easily moveable. When

floor plans change, the units can be

quickly reinstalled.

Easy-to-use controls

The microprocessor-based control in

the high-wall unit is easy to use, per-

mitting easy changes for maximum

comfort. The microprocessor offers

the ultimate in comfort and efficiency.

All units automatically restart and

retain their memories after a power

failure, eliminating unnecessary ser-

vice calls and service disruption. These

high wall units are equipped with a

wireless remote controller.

Accessories

Customizing these duct-free split sys-

tems to your application is easily

accomplished. Low-ambient tempera-

ture capability (permitting cooling

operation down to –20 F outdoor

ambient) is easily added on all units.

Adding a condensate pump acces-

sory to the high wall fan coil provides

installation flexibility.
