Figure 3-1 shows a typical DW-68 Double Wall S/W Heater with all ECS upgrade items
installed. Upon completion of all upgrade procedures in Section 4, the ECS upgrade heater must
be thoroughly checked to ensure that all required external connections have been made to the
modified Heater. In addition, the ECS Control system adjustments must be made prior to placing
the Heater back into service.

The following items must be checked to ensure the proper connections have been made:
1. Drain Connection
Ensure that the side of the plugged Drain Ball Valve has been replaced and that
all external drain piping is reconnected.
2. Cold Water Inlet
Ensure that the Cold Water Inlet Flange is connected to the cold water inlet piping.
3. Steam Line
Ensure that the Steam supply line is connected to the inlet of the CXT-E Control Valve.
4. Condensate Line
Ensure it is connected to a nearby drain or condensate collection system.
5. Electrical Power
Ensure that AC power (110 to 240 volts) is connected to the ECS Control Box.
3.2 Adjustments
Prior to placing the unit into operation, the CXT-E Actuator, ECS Temperature Controller and ECS
Over-Temperature Switch must be set. The adjustment procedures for these items are provided in
