AK110 Chemical Controller Installation and User's Guide
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
