EASY LINK SYSTEM 
The T-K3/T-K3-Pro can be connected with other T-K3/T-K3-Pro’s with communication cables to 
work as a multiple manifold system. 
•  The Easy Link system can connect up to 4 units. 
•  A communication cable (gray color) comes with each unit.   
You can manifold from 2 units to 4 units without a multi-system controller. A 4-unit system has

other additional units will only work as individual units.
