HEAT

PUMP

provides

The

Heat

Pump operates on

a

very

simple

principle

During the

cooling

cycle,

the unit absorbs heat from

the air

inside

your home and transfern that heat In the

outside. During the healing

cycle, the

unit absorbs hrat

from

the

outside air

and

transfers that heat into your

When

it

mrnoves

heat and moisture from the

air

The

is cooled

by

the evamriza-

tion

of
