AK1200 Flow Cell Installation 3.3.1 Tools & Supplies Needed In order to install the AK1200 flow Cell, you will need A Phillips screwdriver A drill A 1/4" drill bit A 1/4" NPT tap A small flat head screwdriver A 1/2" poly tubing Remove flow cell from shipping carton and make sure all parts are included with AK1200 flow cell. - Page 10 3.3.4 mounting the Flow Cell Select a suitable location for the flow cell meeting the following recommendations: • The sensors should be away from direct sunlight, as this may affect the readings. • The location should be where some water spillage will not damage anything. Preferably below the level of the controller.
- Page 11 WArNINg Securely fasten all electrical, water, and chemical lines. Locate chemical feed pumps and chemical storage tanks in a safe and secure area. WArNINg Check filter daily for debris buildup and clean as needed. To clean filter, turn the flow cell inlet and exit valves OFF, remove filter cover and filter, being careful not to loose seal.

Page 17: Chapter 4 Sensors
CHAPTER 4 SENSORS The AT-8 can accept readings from a wide variety of sensors. Each sensor has its own unique circuitry that is con- nected directly to the micro-controller for measurement. Isolation of each sensor ensures more accurate measure- ments. The AT-8 measures the following sensor measurements with the listed characteristics: Range: 4.22 to 9.78, ±0.02. -
Page 18: Flow Sensors
Flow Sensors The AT-8 is able to recieve information from one flow switch, provided with the Ak1200 flow cell This flow switch is used to indicate flow through the flow cell and determines when it is OK to feed chemicals in to the system. The AT-8 will not allow chemicals to feed if there is no flow in the system. -
