ELECTRIC CABINET BASE CONVECTION STEAMER, ECX-16, ECX-24
5.0 OPERATION INSTRUCTIONS FOR BOILERS WITH CSD-1 CONTROLS
Start-up Procedure
1. Close the manual blowdown valve, if so equipped.
2. Open cabinet door and turn "ON" power switch.
The green pilot light will come "ON." Water will begin to enter the boiler. When enough
water has entered the boiler, the (amber) "STANDBY" pilot light will come on.
3. Press the "RESET" switch to begin boiler operation. The "STANDBY" pilot light will go off
and the boiler will begin operation.
Normal Boiler Operating Cycle
Water Fill Cycle
On the initial filling of the boiler, the reset switch must be activated to initialize the safety lockout
circuit. Once the water in the boiler has reached the proper level, the level control will stop the
flow of water to the boiler. As water is consumed in the production of steam, the level control
will supply additional water to the boiler.
Firing Cycle
The elements are operated by pressure sensing devices. On initial operation, the boiler should
reach 14 psi in approximately 15 minutes. At this point, the operating pressure switch will open,
de-energizing the elements. Thereafter the operating pressure switch will cycle the elements
between 9 and 11 psi boiler pressure.
Condensing Drain
A thermostat is located in the drain assembly and is activated by the temperature of steam.
The thermostat operates the cooling solenoid, supplying water to the drain to condense the
steam.
Automatic Blowdown Valve
If the unit has an automatic blowdown valve, it is activated when the main power switch is
activated. The boiler will be drained should the main power switch be turned "OFF."
