A (0501) FIG 1 - VERTICAL AND HORIZONTAL APPLICATION VERTICAL/HORIZONTAL INSTALLATION REFRIGERANT MAINS The unit is shipped for vertical installation with a vertical air discharge as shown in Figure 1, but may be converted to other arrangements per the following instructions. Many service problems can be avoided by taking adequate precautions to provide an internally clean and dry system, and by using procedures and materials that conform with established standards.

035-12124-000 Rev. A (0501) NOTE: To minimize the possibility of system failure due to dirt and moisture, a filter-drier must be installed in each liquid line as close to the evaporator as possible. Filterdriers are not supplied with the evaporator blowers. They are supplied with the matching condensing sections. The temperature required to make or break a brazed joint is sufficiently high to cause oxidation of the copper unless an inert atmosphere is provide.

All supply air motor pulleys are factory set at two “turns open.” After the supply air blower motor is operating, adjust the resistances in both the supply and the return duct systems to balance the air distribution throughout the conditioned space. The job specifications may require that this balancing be done by operation, check the belt and pulleys for tightness and alignment.
