Daikin Packaged Rooftop System DPS012AHME4DV-4

The supply, condenser and exhaust fan motors are permanently lubricated and require no periodic lubrication.

Each unit as shipped is trim balanced to operate smoothly. To provide satisfactory operation after shipping and installation, use accepted industry guidelines for field balancing fans.

NOTE: Excessive vibration from any cause contributes to premature fan and motor bearing failure. Monitor overall vibration levels every six months of operation. An increase in levels is an indication of potential trouble.
