LB600 AIR DISCHARGE
The LB600 blower and coil section are shipped separately and must be joined in the field. The blower section can be mounted either above the coil for a vertical positioning or beside the coil for horizontal positioning. Both vertical and horizontal positions can be arranged for upward, downward, or horizontal air discharge.

FIGURE 8 - LB600 AIRFLOW ARRANGEMENTS
The coil section and the blower section may be assembled together as shown in 8. All arrangements may be by rear- ranging the panels as shown.
When arranged vertically (8, arrangements 1 through 3), the LB600 can be set directly on any floor or platform that is capable of supporting its weight.
When arranged horizontally (8, arrangements 4 through 7), the evaporator coil section can be set directly on the floor, but a 9" support is required under the blower section to stabilize the unit. The support should extend the full width of the blower section and be located under the edge away from the evaporator coil section. If the unit does not have to be secured to the platform, the 9" support will not have to be bolted to either the blower section or the floor.
The evaporator blower arrangement 7 shown in 8 is not rec- ommended for bottom support due to interference with the ductwork connection.
NOTE: Ductwork should never be used to support the blower section. Refer to duct connection for more information
UNIT INSTALLATION
LOCATION
The evaporator blowers are not designed for outdoor installa- tion. They must be located inside the building structure, either inside or outside the conditioned space where they are protected from rain and other such moisture.
The unit should be located as close to the condensing unit as practical and positioned to minimize bends in the refrigerant piping.
Units being installed vertically or horizontally can be set directly on a floor or platform, or supported by metal or wooden beams.
Units being installed horizontally (LA300, LB360 & LB480 only) can be suspended from above as shown in figure 12. Refer to form
RIGGING
Care must be taken when moving the unit. Do not remove any packaging until the unit is near the place of installation.
SPREADER BARS SHOULD BE USED BETWEEN THE SLINGS TO PREVENT CRUSHING THE UNIT FRAME OR PANELS. When preparing to move the unit, always deter- mine the center of gravity of the unit in order to equally dis- tribute the weight. Rig the unit by attaching chain or cable slings around the bottom skid. A lift truck may be used to raise a unit to a suspended location. Refer to Table 2 for the total unit operating weight.
CLEARANCES
A
Some clearance will also be required for the duct and power wire connections. A clearance equal to the unit width is required on one end of the unit if the blower shaft or evapora- tor coil is to be replaced without moving the unit.
