ELECTRIC CABINET BASE CONVECTION STEAMER, ECX-16, ECX-24
6.0 PERIODIC MAINTENANCE
WARNING: Disconnect the unit from the power supply before
cleaning or servicing appliance.
Be sure to flush your boiler water level control daily. Failure to follow this procedure can cause
the control to malfunction resulting in serious boiler damage.
The Boiler Water Level Control installed on your boiler requires periodic maintenance. As boiler
water circulates into the float chamber, sand, scale and other sediment may be deposited in the
float chamber. While the chamber has been designed with a large accumulation bowl, it is
necessary to flush the sediment from the chamber by blowing down the control so that the
accumulation of sediment does not interfere with the movement of the float in the control.
Control must be flushed at least once a day.
CAUTION: Protect yourself. When flushing control, hot water and
steam will flow out of the drain.
When flushing control, note water level in gauge glass, allow the boiler to fill if necessary, and
also to come up to temperature.
Before flushing control, note that water level in gauge glass is within operating range and the
boiler pressure is at least 6 psi. While the boiler is being operated, open blowdown valve at
bottom of control by rotating the handle counterclockwise about 1/4 turn to fully open the valve.
Opening the blowdown valve also checks the cut-off operation. Float should drop shutting
steam off, hot water and steam will flow out the drain flushing away sediment.
