TO INSTALL FLOW CONTROL VALVE HANDLE 1 The flow control valve handle Genuine Hayward Part (CLX200PA) is furnished in two pieces. 2 To install push the handle into the stem and fully install stem into body. You may have to remove handle and reposition to assure the stem is fully seated. 3 Remove handle by pulling straight out. 4 Apply a single drop of Super Glue to the end of the stem, push on handle, positioned in the OFF position. Apply pressure for 30 seconds.

My dog chewed the knob off pretty flush with housing, how does the stem itself come out. Is the stem just pressed in??
 Reply

The stem itself is simply pressed into the Hayward CL200 chlorinator, so you may want try some needle nose pliars to see if you can pull out the broken stem.

Our knob has a fairly large wing on one side and a small protrusion on the other side. Which part should be pointing to the number we want for chlorine use? Thanks (seems like a dumb question...last person to work on this pool didn't leave very good directions.)

The Control Assembly Knob that have the large wing is side that you would adjust to the number that would want your chlorinator to be set at.

My CL220 flow control knob has a slow leak. Believe it needs a new o ring. Does it take one or two o rings and where can I get them? I removed the knob and my unit which is more than 10 years old has one o ring.Thank you.

Hello Tom- There are two o-rings on the knob control. I checked and they no longer sell just the two o-rings by themselves. You would have to purchase the Knob,control Assembly W/o-ring (clx200pa) part # 2110-08a.

The chlorinator is leaking from the adjustment knob. I would like to replace it, but I can't get the old knob off. Am I supposed to pry the handle off or screw it off?

How do you remove and replace the knob control clx2009pa

I have an older version but I simply had to pull it out from the chlorinator. The old one was not really easy to pull out but I eventually worked it out by twisting and turning it while pulling.

There is a slot in the knob almost opposite of the pointer. Place a small slotted screwdriver in the slot and gently push in while unscrewing the knob past the highest setting until it is out.
