What is the difference between a CL200 and a CL220?
The difference between the two units is how they are installed. The CL200 is installed in-line. This means that it is directly installed into the rigid PVC plumbing lines. The CL220 is an off-line chlorinator and is attached to the PVC plumbing lines through the black tubing and saddle clamps included with the unit. The output and types of chlorine dispensed are the same.
