Product Desciption

The CL200 Inline Chlorinator is designed to automatically feed chlorine to your inground pool by working with your existing pump and filter system.  Returning water to the pool flows through the chlorinator which is plumbed inline after the filter.  A simple dial valve allows you to easily control the amount of chlorine being dispensed.  No more floating chlorine dispensers in the pool or manually adding chlorine.  The CL200 sanitizes your pool automatically, holding 9 lbs of Trichlor tablets or sticks.  Hayward chlorinators are made from sturdy ABS thermoplastic and feature a durable Viton seal for the lid.

Question

Asked on 07/25/2015 by RICHARD CORELLI

On the outlet side of the chlorinator is there a check valve or anywhere on the chlorinator?

Inyo Answer

Answered on 07/29/2015 by Product Specialist Lennox H.

Hi Richard, The Hayward InLine Chlorinator (CL200) can only flow one way so that would indicate that it has a check valve within the chlorinator. However it does not show as a replacement part.

Unfortunately the CL-200 base is not removable. It is an integral part of the Chlorinator.

Question

Asked on 07/01/2015 by Mike Davis

I have a 30,000 gal. in ground pool. Which chlorinator would go best with this pool? I'm having trouble keeping the pool stable by using the 1 skimmer basket to place the pucks in. I think it had a chlorinator on it at one time that someone has cut out and replaced with a 1-1/2" pvc pipe. Want to get the right one.

Inyo Answer

Answered on 07/01/2015 by Product Specialist Hector F.

This chlorinator would be a very good option. As long as the flow through the chlorinator is at that needed 50-90 gallons per minute then it will work great. Also please be sure that the stabilizer and or also known as the cyanuric acid level is in par, for that will also aid in keeping the chlorine level stable.

If you click on the main picture, it will enlarge and show you a better version of the label. If you look at it as a clock face - then 1:00 will be full open and 10:00 would be closed.

Question

Asked on 06/27/2015 by

difference versus offline 220 chlorinator?

Inyo Answer

Answered on 06/27/2015 by Product Specialist Hector F.

The only real difference between these models is that the CL200 is designed for inline use being plumbed in while the CL220 is for offline using flex tube clamped to the plumbing.

Question

Asked on 06/22/2015 by Jerry Shannon

I just ordered a CL200, the two fittings to use for my flex hoses and a check valve. On the check valve, I know it goes prior to the chlorinator but as I have flex hoses and not rigid schedule 40 plumbing ( above ground 21x41 pool) how will the check valve mate up with the 1.5 inch flex hoses?

Inyo Answer

Answered on 06/23/2015 by Product Specialist Lennox H.

Jerry, You will have to use PVC for the check valve and then connect the flex hose to the PVC. The pressure will be to much for the flex hose  going into the check valve, it may cause it to leak.

Question

Asked on 06/19/2015 by Jerry Shannon

which unit should I use for my above ground 21x41 pool. The CL220 or another unit such as the NA342? I have flex hoses so I would need the adapters and check valve. Of the 2 units which one is your suggestion for me to order. Will the NA342 perform as well as the CL220?

Inyo Answer

Answered on 06/19/2015 by Product Specialist Charlie R.

Mr. Shannon,Both units will work on your pool. However, one of the major differences is the NA342 does not come with any hoses. It must be plumbed inline with the rest of your equipment. On the other hand, the CL220 is an offline unit and comes with all necessary tubing and clamps.  The CL220 is sold more frequently.

Question

Asked on 06/17/2015 by Jim Kee

After adding chloro tabs to my CL200 a couple of weeks ago, my chlorine rose to 10 ppm within 2 days when the dial was set to 2. The unit is about 5 yrs old and setting the dial to 2 usually keeps the Cl at 2-3 ppm. Over 10 days ago I set the dial to off and the ppm still hasn't gone down. The dial still stops when turned to off or full. Do I need to replace the dial or do I need a kit OR should I replace the CL200?

Inyo Answer

Answered on 06/19/2015 by Product Specialist Lennox H.

Jim, You can replace just the Control Knob Assembly W/O-ring (CLX200PA) or replace the complete Hayward InLine Chlorinator (CL200) unit since it is 5 years old.

Question

Asked on 06/16/2015 by Jerry Shannon

I have an above ground set up and use flex hose not rigid schedule 40 pipe. My pool is 21x41 oval. I have a 1.5 hp Hayward Power Flo Matrix pump. Which inline chlorinator model would I use and can I get the fittings to use the flex hose with.

Inyo Answer

Answered on 06/18/2015 by Product Specialist Lennox H.

Jerry, If you're using 1-1/2" flex hose you can use the Hayward InLine Chlorinator (CL200) with the Union Connectors (SP1500UNPAK2C).

Question

Asked on 06/16/2015 by Jerry Shannon

Do I need the check valve to go with the Inline chlorinator for my above ground pool. The filter and pump are on ground level and under the water line.

Inyo Answer

Answered on 06/16/2015 by Product Specialist Dennis R.

Jerry, It is common practice to install a check valve before a chlorinator to keep the more concetrated chlorine from backing up into the filter and pump when the pump is shut off.

Question

Asked on 06/15/2015 by Jerry Shanon

I have a 21x41 above ground pool. Completely decked in. If installing a inline unit, do I need a check valve in place as well? The unit will be under the deck but below the water level of the pool.

Inyo Answer

Answered on 06/18/2015 by Product Specialist Lennox H.

Jerry, A check valve is required to protect chlorine from back flowing into your heater or filter, whichever one you have installed before the chlorinator.

Question

Asked on 06/05/2015 by Allan

I just replaced my Hayward Chlorinator with a new one, same model, CL200. I installed new lines and fittings that came with it. I have two questions. First, the Chlorinator is not completely filling with water...maybe 1/2 full. Why? Second, with 7 tablets in the Chlorinator, and the adjustment set to the maximum, and my chlorine readings are constantly low (.1). Why would it not be reading quite high, and then require me to reduce the setting. Same problem with the old one. Thanks for your help.

Inyo Answer

Answered on 06/07/2015 by Product Specialist Alex V.

Allan, It is common for the chlorinator to remain half empty. When you first put the tablets in, it will take a few days for you to get a chlorine reading since they are slow dissolve tabs. You can try shocking the pool when you first put in the tabs to get a chlorine reading.

Question

Asked on 05/26/2015 by Mark

My Hayward Chlorinator no longer dissolves the salt tablets. To me this means the water flow is bypassing the salt storage area. Is this a simple fix (e.g. cleaning debris out of the intake) or do I need to replace the unit?

Inyo Answer

Answered on 06/03/2015 by Product Specialist Lennox H.

Mark, You can try cleaning out the chlorinator by pouring hot water down the chlorinator. If that doesn't work then replacing the chlorinator will be your next option.

I pump untreated 'spring water through a sediment filter, then into a 1,500 gal storage tank. Can I add your chlorinator to the 1 1/2 inch line going INT0 the storage tank, immediately after the sediment filter? From storage, water goes to a 'pressure tank' and through two 'whole house' carbon filters BEF0RE branching off for use by my family. Is your chlorinator 'adjustable' to our water’s 'chlorine' needs, if any? We test water weekly. Thanks,

Question

Asked on 04/23/2015 by Kathy Money

I have an 18x36 in-ground chlorine pool with an inline chlorinator that was installed when pool was constructed in 1997. Haywayd system, screw off lid with drop in tablets. Dial it in and leave it. I still do the weekly check and treatments if necessary but my question is: I have been told that an inline chlorinator can only be used on saltwater pools. Please respond with information.

Inyo Answer

Answered on 04/23/2015 by Product Specialist Lennox H.

Kathy, In-line chlorinator are made for customers who uses chlorine tablets to chlorinate their pool. Saltwater pool wouldn't need an in-line chlorinator because the chlorine is generated with a saltwater system.

Question

Asked on 04/10/2015 by

Have 2 inch piping through whole system with water features. 55 gpm pump, cartridge filter. Would putting this in create a restriction dropping to 1 1/2 pipe? Would I be better off with a off line? I'm replacing a pentair salt chlorinator and did not know if would be same unions. Can you give thread dimensions? Thank you in advance.

Inyo Answer

Answered on 04/13/2015 by Product Specialist Patrick P.

Yes putting the Hayward CL200 on 2" plumbing would cause a bit of a flow restriction as if you look through the 1-1/2" port it actually bottle-necks down to about 3/4" at its narrowest point. The offline version does have some issues with the tubes getting clogged. I would suggest the Rainbow 320 Inline chlorinator as it is a straight 2" port and has minimal to no flow restriction on 2" plumbing.

Question

Asked on 03/15/2015 by Bruce

I am putting in a small in ground fiberglass pool, +/- 2500 gals and I am installing a 40 watt uv sanitizer and an ionizer. I understand I will still need to add a small amount of chlorine, equivalent to tap water. Is the lowest setting low enough for this application?

Inyo Answer

Answered on 03/16/2015 by Product Specialist Robert M.

Bruce - The CL200 , set on the lowest setting, may produce too much chlorine for your application. We would recommend the Rainbow 320. The 320 has the option to add a spa chamber which allows you to lower the chlorine output by using smaller tabs.

Question

Asked on 09/26/2014 by Guest

I have a Hayward inline chlorinator now and for approx 10 years. For the past 4-5 years we have difficulty unscrewing the top off to add the chlorine and to the point i can no longer add the chlorine myself. I need to ask someone else to do it and it is difficult for them as well. We would like to replace the chlorinator but afraid to get this same model with a screw top as we may have the same difficulty. Does Hayward sell a latch-on type lid rather than a screw-on type?

Inyo Answer

Answered on 09/26/2014 by Product Specialist Patrick P.

Unfortunately Hayward has not changed the design. The best way to prevent this from recurring is to keep the lid o-ring lubricated and to use the lid wrench - Part number 0211-0 or click on this link -  http://www.inyopools.com/Products/07501352020738.htm#parts

You can use flex pvc or hose to plumb in the chlorinator. Keep in mind that both will deteriorate at a faster pace vs hard pvc and will need to be replaced eventually.

What is the difference between an inline and offline chlorinator?

Inyo Answer

Answered on 01/30/2012 by Product Specialist Patrick P.

An inline chlorinator would be plumbed directly inline with the plumbing.  For an existing pool, this would mean a section of pipe would need to be cut out to install the chlorinator.  An offline chlorinator attaches to existing plumbing by chlorinator tubing (holes would be drilled into existing pipe to attach the tubing.)

Question

Asked on 11/21/2007 by Guest

How do I know if one chlorinator is enough for my pool?

Inyo Answer

Answered on 11/21/2007 by Product Specialist Patrick P.

The Hayward CL200 or CL220 chlorinator will provide enough chlorine for up to 40,000 gallons of water.  You would need to calculate the volume of your pool to determine how many chlorinators you would need.  For example, if you have 60,000 gallons then you would use two CL200 or CL220 chlorinators.

Question

Asked on 04/02/2007 by Guest

Does the in-line chlorinator come with a check valve, or must it be purchased separately?

Inyo Answer

Answered on 04/02/2007 by Product Specialist Patrick P.

No this does not come with the check valve. We would highly reccommend purchasing one of the check valves listed on this page http://www.inyopools.com/valves_flo_check.aspx 

Question

Asked on 03/10/2007 by Guest

Is there a feedback mechanism that tells the unit the chlorine balance in the pool? Is this a way for me to automate addition of clorine to keep it always at the correct level? Or, just another place to put the tab aside from the the drain basket?

Inyo Answer

Answered on 03/10/2007 by Product Specialist Patrick P.

There is a dial on this unit which has a setting from 1-10 If you set the dial on 1 it will be letting the least amount of chlorine to the pool and if you have it set at 10 this would send the most amount of chlorine to the pool. So you can automate the feed of chlorine to the pool but you will still need to manually test your water. We do not recommend placing tablets in the skimmer basket because this high concentration of chlorine goes directly back to your pump and can cause corrosion to your pool equipment. If you do not go with the automatic chlorinator we would recommend at least going with one of our floating chlorinators so you do not damage your equipment you may view our floating chlorinators here http://www.inyopools.com/chlorinators_floating.aspx

   (5 out of 5 Stars) Great Chlorinator

Reviewed By: from Enterprise, AL ()

Pros: Makes keeping the chlorine level in your pool easy and trouble free.

Cons: You must be careful when putting tablets in the chlorinator as the chlorine smell is very strong.

This CL200 Hayward chlorinator was a replacement for my 12 year old Chlorinator, which I cracked by accident. The new chlorinator works very well and is a duplicate of the old one, but shinier. Works well, lasts a long time. Get the union kit to ease installation now and in the future.

   (4 out of 5 Stars) hayward inline chlorinator

Reviewed By: from NJ ()

Pros: reliable long lasting unit

Got this at a better price than I could find elsewhere. Since I already had the same unit, I cheaped out and didn't buy the connecting pipes. Bad move. I can't get the old ones off. So currently I have the old unit installed with the new units top. Guess what, that solved my problem which was leaking and air in the pool return lines. A "tune up" kit is sold separately with O-rings for the top that probably would have solved my problem. Oh, well I'm going to order the connecting pipe and replace the unit as it is 15 yrs old anyway.
