DESCRIPTION
Evaporator blower units are desi
g
ned with two distinct mod-
ules to provide maximum application flexibilit
y
. The 30 and 40
ton units are shipped as sin
g
le packa
g
es with the blower
module mounted on top of the coil module, The blower mod-
ule can be repositioned in the field to meet almost an
y
instal-
lation requirement. Blower and coil modules for the 50 ton
units are shipped separatel
y
to simplif
y
handlin
g
. These mod-
ules can be connected in the field with the same flexibilit
y
as
the smaller units.
The blower module includes the blower wheels and room for
a field-mounted motor and drive. The coil module includes
direct expansion coils, 1 in. throwawa
y
filters, liquid line sole-
noid valves for both capacit
y
reduction and pumpdown, ther-
mal expansion valves, distributors and a condensate drain
pan.
Ever
y
evaporator coil is pressurized with air to 325 psi
g
and
leak tested under water. After the headers are brazed onto
the coil and the coil is installed in the unit, the coil is pressur-
ized with a combination of refri
g
erant-22 and nitro
g
en to 150
psi
g
for pressure testin
g
and additional leak testin
g
. After the
coil is evacuated and deh
y
drated, it is pressurized with a
holdin
g
char
g
e of refri
g
erant-22 for stora
g
e and/or shippin
g
.
Steam coils, hot water coils, base sections, suspension hard-
ware, blower motors and drive packa
g
es are available as
field-installed accessories to provide additional application
flexibilit
y
.
These evaporator blowers, combined with condensin
g
units,
provide
y
ears of quiet, efficient and dependable operation.
These units are manufactured under ISO 9001 Qualit
y
S
y
s-
tem Certification.
MODULAR DESIGN
These evaporator blowers can be arran
g
ed for a variet
y
of air
dischar
g
e patterns in either the horizontal or the vertical posi-
tion.
The above illustration shows three of the common installation
arran
g
ements. Refer to the unit installation instructions for
other possibilities.
Units ma
y
be bottom-supported or ceilin
g
-suspended and
can be arran
g
ed to meet almost an
y
space or duct require-
ments. Each unit is available with a choice of blower motors,
drive packa
g
es and other accessories to make them suitable
for most applications.
FACTORY-MOUNTED COMPONENTS
PART LOAD OPERATION These evaporator blowers have
multiple coils with pre-piped distributors, expansion valves
and solenoid valves. Field modifications are not required for
part load operations. Capacit
y
reduction not onl
y
provides
economical operation, but also maintains more even temper-
ature and humidit
y
levels in the conditioned space.
EASY SERVICE Serviceable expansion valves are provided
on ever
y
unit. These superior valves are factor
y
-installed to
provide man
y
y
ears of trouble-free operation. If service is
required, it is not necessar
y
to unbraze an
y
joints.
PUMPDOWN Evaporator blowers include a solenoid valve
for non-rec
y
clin
g
pumpdown. When the coolin
g
requirement
in the conditioned space is satisfied, the refri
g
erant is
pumped into the hi
g
h side of the s
y
stem.
ACCESSORIES
BASE SECTIONS (30 and 40 ton onl
y
) Base sections can
used to elevate units above the floor. If desired, outdoor air
ma
y
be introduced throu
g
h these sections b
y
cuttin
g
an
access openin
g
to accommodate the outdoor air duct con-
nection. These bases have a durable finish to match the
evaporator blower unit. The
y
ma
y
have to be insulated for
certain applications.
SUSPENSION PACKAGES These accessories can be used
to suspend horizontal units from above without interferin
g
with access to the unit. The
y
can also be used for elevatin
g
a
floor-mounted unit (either horizontal or vertical) to provide
additional hei
g
ht for the installation of a trap at the conden-
sate drain connection. All suspension packa
g
es can be used
with vibration isolators.
HOT WATER COILS Drainable water coils are available for
field installation between the blower and the coil modules of
both horizontal and vertical units. Since their casin
g
s match
the dimensions and the finish of the basic units, the
y
become
an inte
g
ral part of the unit after installation. The coils slide out
of their casin
g
s for eas
y
installation. Coils have copper tubes
that have been mechanicall
y
expanded into aluminum fins.
Both headers are located on the same end of the coil. Coils
are leak-tested at 325 psi
g
under water and dried before their
connections are capped for stora
g
e and shippin
g
.
STEAM COILS (LEU360 onl
y
) A steam coil is available on
the LEU360 for installation between the blower and coil mod-

ules of both horizontal and vertical units. Since the casin
g
matches the dimensions and the finish of the basic unit, it
becomes an inte
g
ral part of the unit after installation. The coil
slides out of the casin
g
s for eas
y
installation and is pitched in
the casin
g
s to facilitate condensate draina
g
e. The coil has
copper tubes that have been mechanicall
y
expanded into alu-
minum fins. Both headers are located on the same end of the
coil. The coil is leak-tested at 325 psi
g
and dried before the
connections are capped for stora
g
e and shippin
g
.
BLOWER MOTORS Different HP motors are available for
each unit to meet almost an
y
air deliver
y
requirement. All
motors are UL approved, have permanentl
y
lubricated ball
bearin
g
s and are field-mounted within the insulated cabinetof
the units to minimize the transmission of sound to the sur-
roundin
g
space. All motors have inherent protection except
those available for the 50 ton unit. Motors for 50 ton units
require a starter and overload elements
DRIVE PACKAGES Different size pulle
y
s and belts are avail-
able for each unit to provide a blower RPM ran
g
e to meet
almost an
y
air deliver
y
requirement. Variable pitch motor pul-
le
y
s can be adjusted to provide the proper blower RPM. All
drive packa
g
es are rated at least 25% above the nominal HP
ratin
g
of the blower motor. Two-
g
roove pulle
y
s and two belts
are provided on ever
y
drive packa
g
e rated at 5 HP and
above.
STARTERS AND HEATER ELEMENTS (50 ton onl
y
) The
blower motors that are available for the 50 ton units do not
have inherent protection and require external motor overload
protection.

the LEU600. These motors require external protection
(starter with overloads and periodic lubrication). All
motors have a solid base.
