I am moving my Hayward CL 100 Chlorinator between the heat pump and return of water to pool. Do I need a check valve installed at beginning of unit where pvc pipe comes to Chlorinator or does the CL 100 have it built in? It will be below water level and almost on the ground. How should I install this and can you send me instructions to help with this?
It is definitely recommended to place a check valve between the heat pump and chlorinator. Being that these chlorinators are not all installed in the same application the only installation instructions would be what the manufacturer provides in the manual that you can view here.
how do i clean chlorinator stopped up
Hi. The best way to clean out a clogged chlorinator is to pour or run hot water through it.
Do you sell the tool to remove the cap on this unit.
Hi, Dennis. Unfortunately, a lid wrench is not for this unit.
I use bromine 1" tables. Can I use the CL100 from Hayward inline unit. My pool is at 18,000 gallons
Yes, you can use bromine tablets in the Hayward CL100. It may be ideal to use a larger chemical feeder, based on the design flow rate of your pump.

Were you wanting to know more about it or just wanting to buy it? If you're ready to buy then you can give us a call to place an order or purchase it off of our website.
On the CL100 chlorinator, the control knob pointer is ambiguous. Which is the end that points to the Hi or Low settings, the big end or the small end?
Hi, The bigger end indicates the desired settings for the chlorinator.
I need the lid /cap for the chlorinator,do you just sell that?
Yes we do carry the Hayward CL100 Lid here.
i'm trying to find and an automatic chlorine feeder for my above ground Intex pool rated at 4,000 gal, which has an intex sand filter and pump unit with all 1 1/2 flexible hoses, so could this install inline after the sand filter using the same hose connections that intex uses for their hoses? if not, then what chlorinator would work without it being installed off line since all my hoses are flexible 1 1/2" hoses and can not be drilled or attached to properly.
Hi Steven, The 4.2lb In Line Chemical Feeder is what is recommended to you with your system if you have a 1-1/2" thread port on your sand filter.
does the chlorinator have to be installed at ground level or can I use the pipe to hold its weight just downstream from my filter?
This chlorinator can be installed inline and not resting on the ground.
I may have tightened the top to much and cannot get it off... is there a tool that fits the grooves on the top, to get it off?? Thanks!
Hi Larry, There is not a Lid Wrench for the CL100, but you can use a strap wrench to remove the lid.
can this be used on a 5000 gallon pool
Yes this chlorinator can be used in a 5k gallon pool as long as there is the required 30-50 gallon per minute rating in your system..
I set my dial at 1 but still seem to,get an awful amount of clorine. Do you sell a replacement dial?
Yes the dial can be seen here. You can always use less chlorine tablets for the time being as well until the chlorine level lowers some.
Would this cap fit a 26 year old Haywood model 3000D?
Hello Sandy, Please contact Hayward at (1-888)-Hayward. They would be able to decide if this lid will fit the older model you have.
Do any of the Hatward clorinators have a clear window to see level of chlorine tablets???
HI Christine Currenty do not have a Hayward model that has a clear top. However CMP has a model 25280100 • Holds (12) 3 in. tablets or 5lbs of 1in. tablets• Treat pools from 5,000 to 50,000 gallons• Clear lid for easy serviceability• 2 in. unions for quick-disconnect• Superior dial with 100% shut-off• Built in flow meter for easy adjustment• No external hoses• All piping is inside unit to eliminate leaks
My CL 100/200 Chlorinator is not chlorinating my pool; this is the 3rd year of operation. I remove it every winter. Is there there a cleaning process?
The safest way to clean out a chlorinatior is to boil some water and pour it down the chlorinatior. If that doesn't solve your problem the check valve may need to be replaced.
What union connectors are needed for the Hayward Chlorinator model # CL100?
The union connectors kit need for Hayward Chlorinator model # CL100, is part # SP1500UNPAK2.
After two normal seasons of operating fine, all of a sudden the inside of my Hayward 300 chlorinator is turning black. What could be the cause of this? And what could I do to fix this?
If the water feels slightly greasy to the touch, it could mean that the chlorinator has turned black due to an excess of iron and manganese in the water. I would suggest checking the composition of your water at your local pool store or supply company. They should be able to tell you whether or not the pH and total alkalinity are in balance with one another.
Can you use bromine tablets in the Hayward CL100 Inline Chlorinator?
Yes, you can use bromine tablets in the Hayward CL100.
What is the difference between an inline and offline chlorinator?
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.)
How do I determine if the CL100 is the proper size chlorinator for my pool?
The Hayward CL100 or CL110 chlorinator will provide enough chlorine for up to 18,000 gallons of water. If the volume of your pool is greater than this, you would need the CL200 or CL220 model which is for pools up to 40,000 gallons. For pools above 40,000 gallons, you would use multiple chlorinators. For example, if you have 60,000 gallons then you would use two CL200 or CL220 chlorinators.
Does the in-line chlorinator come with a check valve, or must it be purchased separately?
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
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?
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
Can I use granular, or must I use 3" tablets or stick?
We recommend using tablets or sticks, and not to use granular with chlorinators.
