A marked tendency in modern
living is the readiness to adopt
new developments in equipment
and facilities which contribute to
health and the minimizing of ply
sical effffort, says the current bull
letin of the Producers Council,
edited by the department of tech
nical services of the American In
stitute of Architects.
In the electrical field. such de-
velopments have outdistanced all
expectations and the accommoda-
ties provided for many homes
planned but a few years ago are
now found inadequate to permit
the introduction of many of the de-
sirable advances in equipment and
facilities which are deemed essen
tial in a home planned to meet
present-day requirements, 1t Is
pointed out. This has resulted in
no small degree of obSOlesCenCe,
with a corresponding effect on
property values.
In providing adequately for the
electrical facilities now available
for homes of every type with rea-
sonable allowance for future eX-
pansion, modern wiring installa-
tions not only should allow for the
comfort and convenience of mod
ern living but for future develop
ments as they become available.
"Weathermakers."

the bulletin. Built in five sizes,
cooling capacities from 6 to so tons
may be obtained from single unit.
All functional elements-fanS,
filters, coils. controls, motor and
drive-are readily accessible for in
spection. This unit is intended
primarily for installation in con-
cealed locations, from which the
air is distributed evenly through
ducts and outlets to the conditioned
space.
Standard cooling coils, available
for warm weather conditioning,
are direct expansion "Freon-l2," ,"

For cool weather conditioning,
steam or hot water coils and hu-
midifier pan are provided.
Quiet operation is insured by the

welded and dynamically balanced,

vanes of the fans guide air into

increased efficiency. A rugged sheet
steel filter section embodieS ample
filter area for cleaning dust, dirt
and CRIME from air. The filters,
utilizing the impact principle on
viscous odorless wax, have slow in

humidifying, filtering and circulat-
ing the air are provided under auto
matte control Circulating and FL
tering of air in summer can be OBJ
tanned by using a fan in the unit,
and cooling coils are available for
location in the supply duct.
The units are planned primarily
for residence conditioning and
NAV be installed in new or existing
buildings. They are easily adaptable
for replacement of existing warm
air heating systems. Capacities
are varied by changing rate of fuel
burning and by changing fan speeds.
The tWo-stage. tWo-Speed feature
permits operation at low rate of
gas burning and slow fan speed
when the heat demand is normal.
Extremely quiet and entirely eff
cient operation is assured, with quick
response to rapid temperature drop,
