12.6 FanMatrix™ Maintenance
ClimateCraft FanMatrix™ air handling units require
less maintenance than air handling units with belt-
driven fans, but they are not without maintenance
requirements.
1. Remove accumulation of dirt and oil buildup on
or around the motor bearings.
2. Verify all mounting hardware is tight.
3. Verify fan is floating freely and not restricted in
movement.
4. Inspect isolation springs for loose or broken
springs and replace.
For your FanMatrix™ motor to run reliably a relubrication
schedule must be established and maintained. Please
use the following guidelines to build your FanMatrix™
maintenance program:
Recommended Grease:
Polyrex EM (Mobil)
Compatible Greases: Texaco Polystar, Rykon Premium
#2, Penzoil Pen 2 Lube, Chevron SRI
