Operating instructions

. Prevent Brew Basket Overflow on 85 oz. Brew, 4 oz. of Ground Coffee. Total valve time of 236
seconds required for 85 oz. of water. Extend the delivery over a longer period of time, say 5¾
minutes, (or 344 seconds), to prevent overflow of brew basket, by having 3 valve delay period.
Initial Valve time is arbitrarily set at 62 seconds. Program the delay required (i.e. 344–236 = 108
seconds) over 3 pulse cycles, each with a delay of (108 ÷ 3) 36 seconds. To calculate the Pulse
Valve time: Total Valve Time minus Initial Valve Time divided by 3 pulse cycles: 236 – 62 ÷ 3 = 58
seconds.
