Service
Proper identification of your fan is necessary to insure you receive correct replacement parts. The Marley cooling tower serial number can be used to determine the fan and any components installed and maintained as original equipment on a Marley cooling tower. The fan diameter and moment weight class from the blade nameplate (see Figure 8) is required to identify blades for replacement. The fan hub assembly identification number (see Figure 1) is required to identify a replacement hub assembly or repair components. Please provide the Marley sales office or sales representative the necessary information when ordering replacement fans or components.
Blades can be replaced without rebalancing the entire fan.
If rebalancing is desired, contact the Marley sales office or repre- sentative in your area.
