Chemical Feed Pump Location
If unit has not been previously installed, follow the instructions included with the chemical feed pump. Some loads
include power cords already connected to the load and are ready to plug in. If “pigtails” have been ordered with the
Controller simply plug the power cord into the appropriate "pigtail". If "pigtails" are not installed the power cord from
the pump will need to be modified. The list below provides installation recommendations:
1. Mount at least 10 feet from open water.
2. Install the pump below the level of the Controller and away from any other equipment or systems.
This is to reduce any damage to other equipment should the pump leak.
3. Install close enough to the Controller for the feed pump power cords to reach.
4. If "pigtails" are included simply plug in the pumps to the appropriate "pigtail". If pigtails are not installed,
cut the electric plugs from the feed pumps and strip and ferrule the ends.
5. Route the power cords to the Controller through the lower fittings and attach to the appropriate relay
terminals on the relay circuit board. If the wire ends were striped and not ferruled make sure that no frays
of wire are out of the connector as this may lead to a short.

7. When installing metal conduit into the Controller, a ground LUG should be used to connect the conduit to
the relay board ground.
Heater Installation
The Controller third relay can control a heater, turning it on and off based on the temperature settings you have
programmed in to the Controller. The heater control portion of the Controller can be used to maintain a constant
temperature or maintain a temperature during operating hours. Even though the Controller is a very accurate and
reliable device, for safety, always use the over-temp device on your heater to prevent overheating.
1. Always install any heater according to the manufacturer's instructions.
2. Mount the Controller at least 10 feet from open water.
3. Install close enough to the Controller for the wiring connections to reach.
4. DO NOT attempt to power the heater with the Controller controller.
5. A heater unit must always be independently powered, either through a separate cord, or through an
  externalrelayliketheAcu-TrolHAR1relaymodule.(Part#735000060)

Follow the instructions that came with the AK1200 flow cell. This section gives the basic principles to be applied for any
specific installation, which are listed as follows:
1. Turn OFF all equipment including the filtration system.
2. Determine a suitable location for the flow cell. Which should be located where water spillage will not
damage surroundings.
3. Securely mount the flow cell.
4. Install the supply and return lines for each flow cell. Drillandtap¼”holesforthe½”exibletubingorhard
plumb the flow cell.
A. Locate where the water will be supplied from and returned for each flow cell. The most common
location for the water inlet to the flow cell is after the main filter and the outlet after the heater.
B. If there is no suitable location the cell inlet can be after the main pump and the outlet before the main
pump. This method may cause a suction in the flow cell and damage to the sensors. If any chemicals

HARDWARE
Modules are the electronic controls and components that make up the Controller.
Each module has a specific function or functions that tell the Controller what information to accept and what
information to display. The modular design of the Controller enables it to interface with many types of modules
including Sensor, Communication, and Relay modules.
Sensor modules determine the types of sensors signals the control can recieve. There are three sensor modules
currently available for the Controller.
AK111: pH, ORP, temp and heater control. Calculated PPM can also be displayed (Part# 724000010).
AK112: pH, AKColor(PPM), heater control (Part# 724000380)
AK113SC: pH AKColor(PPM) ORP, Temp (Part # 725000390)
The Controller has the ability to work with several types of communication modules. The Controller can communicate
with a PC through an RS232 cable, a standard modem, or a wireless modem.
Controller Modem: High-speed modem. (Part # 725000010)
Wireless Modem: The wireless modem allows the Controller to be accessed over the internet from any PC.
Wireless modems are a perfect solution for installations without phone lines. Please note that the wireless
modem and the standard modem can not be installed in the same Controller.
The Controller is able to automate nearly any device in your pump room. The Controller uses a relay module to turn
electricity to the device on and off. Each Controller can control up to 3 relay modules. Each relay module can control
one device. Relay modules are available in seven different models. The type of relay module used depends on the
load requirements of the device that is controlled with the relay module. To determine the load requirements, please
consult the instruction manual or the device manufacturer. Any combination of the seven models of relay modules can
