other component of the waterflow indi in the field If any other functional part of the detector faulty remove and replace the entire detector Not so may result in the failure of the detector to indicate waterflow condition Mechanism Removal Turn the dial to zero 0 and remove the three screws the delay mechanism in place Gently lift the front of the delay mechanism approxi 30 degrees to clear the paddle lever arm see 1 Pull forward and rock the delay mechanism back and slightly to disengage the switch buttons from the stop Mechanism Replacement Turn the replacement delay mechanism to zero 0 Orient the timer stop as depicted in Figure 2 Note the off in the two vertical faces of the stop and their position Placing the mechanism on a slight angle to the water device as shown in Figure 1 slide the rear of the shaft between the switch buttons until the timer is encountered Rock the delay mechanism back forth to retract the switch buttons and continue to the delay mechanism into position on the plate Check the following before replacing the retaining refer to Figures 1 and 2 Insert the end of the shaft into the rear slot of the enclosure see Figure 1 Rest the paddle lever arm
