Improper belt fitment may cause pulley misalignment, excessive power consumption, reduced belt life, premature bearing wear, and noise. To check belt tension, press the belt firmly at the center of the span to check deflection objective (Figure 12-4).
- Page 20 Consult factory for lubrication intervals under severe operating conditions such as high temperatures, moisture, dirt or excessive vibration. Lubricant should be a high quality lithium complex grease conforming to NLGI Grade 2. ClimateCraft recommends Mobilux EP-2. Storage periods of 3-months or longer require monthly shaft rotation and purging of the grease prior to startup.
- Page 21 Consult factory for lubrication intervals under severe operating conditions such as high temperatures, moisture, dirt or excessive vibration. Lubricant should be a high quality lithium complex synthetic grease conforming to NLGI Grade 2. ClimateCraft recommends Mobilith SHC-100. The use of non-synthetic grease will decrease lubrication intervals by approximately 3 times.
