BLOWER ARRANGEMENTS
Models ED060, 090 and 120 are shipped assembled for verti-
cal supply air operation only (See Figure 5).
Model ED180 is shipped assembled for vertical supply air
(see Figure 6) operation and can also be field converted to
one of three-(3) alternate air discharge patterns (See Figure
7).Converting Model ED180 to an alternate air discharge pat-
tern is accomplished per the following procedures:
1. Remove the panels from the blower section.
2. Remove Phillips machine screws located inside casing
corner angles which hold coil and blower section
together.
3. Rotate blower section for the air discharge pattern
desired.
4. Refasten coil section to blower section with machine
screws removed in Step 2.
5. Before replacing panels, see paragraphs on Duct Con-
nection and Drain connections.
6. Replace panels.
SUPPLY AIR BLOWER ADJUSTMENT
The RPM of the supply air blower will depend on the required
CFM, the unit accessories and the static resistances of both
the supply and the return air duct systems. With this informa-
tion, the RPM for supply air blower can be determined from
the blower performance, Table 8.
Knowing the required blower RPM and the blower motor HP,
the setting (turns open) for the supply air motor pulley can be
determined form Table 12.
Each motor pulley has:
1. A threaded barrel with two flats (or notched recesses
180 degrees apart.
