Replacing Solid-State Timer

Blending - Automatic Type (FE Urns)
Operation:
The agitator pump circuit is programmed to operate
immediately after brewing cycle. The circuit pumps air
through the coffee gauge glass(es) into the coffee
liner(s). The complete cycle takes about 20 seconds. For
additional blending, simply press the BLEND switch.
Maintenance:
• If agitation is not sufficient to blend coffee, check
flexible tubing, and glasses and fittings, for possible air
leaks. Replace as necessary.
• If agitator pump does not operate immediately after
brewing cycle or when BLEND switch is pressed, replace
agitator pump or solid state agitator timer.
• If agitator pump comes on immediately after brewing
cycle, but does not operate when BLEND switch is
pressed, replace BLEND switch.
Blending - Manual Type (CL Urns)
Operation:
Immediately after brewing cycle, depress BLEND switch
and hold for about 20 seconds. Your coffee will be
completely blended and ready to serve.
Maintenance:
• If agitator pump does not operate when BLEND
switch is pressed, replace switch, if pump still does not
operate, replace pump.
