40RU

Fan Motor Lubrication - Fan motor supplied with unit is permanently lubricated and requires no further lubrication.

Fan Shaft Bearings - Size 25-30 units have pillow-block bearings (Fig. 23) that must be lubricated with suitable bearing grease approximately every 3 months. See Table 7 for suitable lubricants.

*Preferred lubricant, contains rust and oxidation inhibitors.

Centering Fan Wheel - If fan and fan shaft assembly are not properly centered, blades may scrape against the blower side scroll plate or may create an objectionable whistling noise. It may be necessary to adjust individual fan wheels or move entire fan shaft. See the following two sections.

Fan Shaft Position Adjustment - Loosen setscrew or locking collar of each fan shaft bearing. Slide shaft into correct position and replace locking collar (Fig. 24). To replace locking collar, push collar up against inner face of bearing. Turn collar in direction of fan rotation until tight, and tighten setscrew. Tightening locking collar in direction of fan rotation results in further tightening of collar should setscrew work itself loose.
