GENERAL
The LA and LB evaporator units are designedfor use with the
HA/HB Series condensing units.Units are designed to match
up with LA/LB series Evaporator Blowers to meet ASHRAE
90.1 standards.
Each unit consists of a coil section and a blower section that
are factory assembled and shipped as shown in figures 3 and
4. These sections may be rearranged in the field for other air
discharge patterns. See figures 7, 8 and 9.
The LA and LB evaporator units have 24 volt normally closed
solenoid valves to match the 24-volt control circuits of the

blower motor and drive packages are ordered and shipped

LA300/LB360/LB480 MOTOR MOUNTING
The LA300, LB360 and LB480 ship from the factory with a
motor mounting adapter plate for use with the 7.5 and 10 HP
motors. If a 5 HP motor is used,the adapter is not necessary
and should be removed and discarded.
LB600 MOTOR MOUNTING
The motor mounting plate will accommodate a 10 or 15 HP
motor. One set of boltholes is provided on each end of the
motor mounting plate for either motor. The motor mounting
plate can be raised or lowered to any position on the adjustment screws to adjust the belt tension for the various pulley
settings to cover the complete range of blower speeds.
The physical size of the 15HP motor reducesthe adjustment
range of the motor mounting plate. To maximize this amount
of adjustment, one set of boltholesis provided near the
adjustment screws on each end of the motor mounting plate
(refer to 4).
For some motor/blower wheel arrangements,however, the
motor cannot be mounted in these bolt holes because the
motor terminal box would interfere with one of the blower section panels. To make these motor/blower wheel arrangements possible, a second set of boltholes is provided near
the pivot bolts on each end of the motor mounting plate.

The motors used withthe evaporator blower are 3-phaseand
can drive the blower wheels from either end of the blower
section. Reversing the direction of rotation can be accomplished by changing the connection of the power supply wiring at the motor terminal box.
NOTE: The 7.5-15 HP blower motors have solid bases
and are not inherently protected. For proper
operation, these motors require overload
heater elements. Please see curent product
price pages for overloads.
Unitary Products Group 7
The 15 HP drive package requires two different lengths of
belts to vary the blower wheel RPM over the complete range
of rated conditions. When the motor is mounted near the
adjustment screws, the two lengths of belt are interchangeable except for the higher and lower limits of blower wheel
RPM. When the m otor is mounted near the pivot bolts, the
shorter length of belt is recommended for the higher blower
wheel Rpm's and the longer length of belt is recommended
for the lower blower wheel Rpm's. See Page 7 for the recommended blower motor locations.
035-18496-000-C-1102
MOTOR MOUNT ARRANGEMENTS
The motor mounting arrangement can be changed to allow
motor access based on the airflow arrangement required.
The recommended motor location for each blower arrangement is as follows.
LA300/LB360/LB480 MOTOR ARRANGEMENTS
The LA300, LB360 and LB480 units are shipped with the
motor mount in locationA as shownin 4. If this is the desired
position, the motor mounting assembly is already in the correct position and the motor and drive package can be
installedwithout modifications.
ADDITIONAL MOTOR ARRANGMENTS FOR LA300/
LB360/LB480
Move the entire motor amounting assembly (both the mounting plate and the channels) so that the mountingplate will be
in the correct location.
1. Rotate the motor mounting plate 180 degrees on the
mountingchannels.(For locations B, andD only! Do not
rotate the plate for location C or E.)

NOTE: The blower section must be lifted off the evap-

channel fasteners. Since these sections have
to be repositioned for the arrangements 2
through 10 and 12 of 6, the motor mounting
assembly should be relocated before the two

LB600 MOTOR ARRANGEMENTS
The LB600 unit is shipped with the motor mount in the standard location as shown in 2.
If this is the desired position, the motor mounting assembly is
already in the correct position and the motor and drive package can be installed without modifications.
RE-LOCATING THE LB600 MOTOR MOUNTING PLATE
The motor mounting plate can bere-locatedin three alternate
positions:
ALTERNATE POSITION ONE
For locating motor mounting plate in alternate position one,
see 3 and re-locate as follows:
1. Remove pivot bolts from the mounting plate.
2. Remove the mounting plate from the adjustment screws.
3. Rotate mounting plate 180.
4. With pivot bolts removed in Step 1 fasten the mounting
plate to alternate position No. one.
5. Fasten mounting plate to the adjustment screws.
ALTERNATE POSITION TWO
The motor mounting plate, the pivot bolts and the adjustment
screws can be m oved intoa position similar to the one shown
as standard in 3 but under the other blower scroll. The framework under each blower scroll has the same bolthole
arrangement.
ALTERNATE POSITION THREE
The motor mounting plate, the pivot bolts and the adjustment
screws can be moved into a position similar to the one
detailed in alternate position one but behind the other blower
scroll. The framework behind each blower scroll has the
same bolthole arrangement.
AIR DISCHARGE CONVERSION
LA360/LB360/LB480 AIR DISCHARGE
The LA300 LB360 and LB480 units are shipped for upflow
operation, but may be converted for any of the illustrated air
discharge patterns shown in 7 and 8. C onvert as follows:
1. Remove the panels from the blower section.
2. Remove the Phillips machine screws located inside casing corner angles that hold the coil and blower sections
together.
3. Rotate the blower section for the desired air discharge
pattern.
NOTE: Before proceeding to step 4, see the section
on the blower motor mounting locations and
mount the blower motor in the desired position.
4. If accessory heating coils are used, mount heating coil
between cooling coil and blower sections. Screw fastening locations are the same for all sections and heating
accessories. If heating coils are not used, fasten coil
section to blower section with machine screws removed
in step 2.
5. Before replacingpanels, see duct connectionsand drain
connections.
6. Replace panels.
