4. INSTALLATION OF RETROFIT KIT ITEMS
When installing the new Electronic Control Valve Actuator and Electronic Control System (ECS)
Control Box, a number of ancillary items must also be installed or replaced. These include a new
Flow Meter, a replacement Water Solenoid Valve and several Temperature Sensors.
To install the Retrofit Kit items, proceed as follows:
4.1 INSTALLATION OF CONTROL VALVE ACTUATOR AND LINKAGE ASSEMBLY
Identical Actuator Assemblies, part no. 69170 are used on all AERCO Control Valve sizes from 1
inch to 4 inches. However, there are two types of Linkage Assemblies designated part no. 24038-
1 and -2 used with different sizes of AERCO Control Valves. Linkage Assembly, part no. 24038-1
is used on AERCO Valve sizes ranging from 1 inch to 3 inches. The 24038-2 Linkage Assembly is
used only on 4 inch Valves. The primary difference between these two assemblies is the Linkage
Assembly Adapter shown in Figure 4-1. In addition, the linkage pin location for 24038-1
assemblies will vary for 1 to 2 inch Valves and for 2 ½ to 3 inch Valves, as shown in the upper
portion of Figure 4-1.
