MAINTENANCE
Periodic Maintenance
The following items require periodic inspection and maintenance:
•
Fans should be checked for proper operation and filters cleaned and/or
replaced on a schedule that suits local ambient conditions.
•
Power wiring connections should be checked and re-torqued every six
months.
•
Refer to the FRENIC-HVAC drive Instruction Manual (INR-SI47-1707c-JE) for
drive maintenance requirements and schedule.
•
Removal of the fans requires depressing the retaining clip and lifting the
assembly out of its location and unplugging the connector. For the 30Hp
model, the nut on the side of the retaining clip needs removed. When
finished, reinstall the nut and torque it to 55-58 lb.in.
•
Refer to the pictures on page 34 for the procedure to re-installing the front
cover of the VFD to prevent damage to the gasket.
