Figure 5-2 shows a typical DW-68 Double Wall S/W Heater with all ECS and CXT-E Retrofit items
installed. Upon completion of all retrofit procedures in Section 4, the ECS Retrofit heater must be
thoroughly checked to ensure that all required external connections have been made to the
modified Heater. In addition, CXT-E Actuator and ECS Control system adjustments must be made
prior to placing the Heater back into service.
