Do you install the chlorinator between the pump and the filter or after the filter
 Reply

A  Answered on 5/5/2020 by InyoPools Product Specialist Alex V.

John, The chlorinator would be the last thing that is plumbed in before the return. If you have a heater, it would be installed after the heater. If you don't have a heater, it would go after the filter. You will also want to install a check valve or plumb in a loop to prevent backflow from the chlorinator when the pump is turned off.

i have a 500 gal pool w/ the 320 but seems to raise the cl2 to, does it matter the amount of tablets in the chlorinator the I've been keeping it full.
 Reply

A  Answered on 6/28/2019 by InyoPools Product Specialist Lennox H.

Hi, Rob. The amount of chlorine in the chlorinator will determine how much chlorine is released into the spa. The more tabs in the chlorinator the more chlorine is released.

What kind of ball valve should I use to slow the flow rate down. I have a 2000 gallon spa and stays at 100 degrees 24/7. If I add one tab to the chlorinator it shoot the levels through the roof overnight and that's just barely opening the valve.

Good afternoon, you can add a ball valve to decrease the flow or would just be adding smaller amounts or bromine to the system.

Hi, Jeremy. It does not matter which port is used. The top port is used in high flow applications.

Hello, what is the max flow this chlorinator can handle? Pad is 2.5” and then goes to 1.5” before going to 3 returns, water slide and 3 waterfalls. Can I place the chlorinator right after the filter and before everything else? Or should some water features be bypassed? Thanks
 Reply

A  Answered on 7/14/2018 by InyoPools Product Specialist Lennox H.

Hi, NT. This unit using the bottom feed port max flow rate is19 GPM and using the top feed is 48 GPM. The chlorinator should be placed after all other equipment with a check valve. 
 Reply


?     Asked on 5/9/2018 by Donald Appel

If I want to use the top feed i would run the longer pipe from the top to the valve. I would leave the valve where it is on the chlorinator. Is this correct?

Hi, Donald. You will have to move the valve to the top and plug the bottom. Instruction are available in the SPECIAL FEATURES AND INSTRUCTIONS section of the Rainbow 320 InLine Chlorinator Owner's Manual

Had Rainbow 320 installed and I have it turned all the way up. The chlorine level will not go up. I keep having to put tablets in the skimmer or shock the pool to get it up. The tablets are dissolving in a few days inside the unit. How do I know if it is getting the chlorine delivered.
 Reply

A  Answered on 5/9/2018 by InyoPools Product Specialist Megan C.

If the tablets are dissolving and you cannot keep a good balance on the chlorine level you may have to much cyanuric acid in the water. Please view How To Break Chlorine Lock Link http://www.inyopools.com/HowToPage/how_to_break_chlorine_lock.aspx and have the water tested with a professional.

Hi, Ann. You will need to reduce the amount of chlorine tablet in the unit. Also, monitor the pool water temperature. The colder the water the less chlorine you'll need.

i have a 37000 gallon pool. How long should I have to run my pool to get the bromine to the level it should be?
 Reply

A  Answered on 9/19/2017 by InyoPools Product Specialist Lennox H.

Hi, Laurie Bellows. It's hard to say how long. It depends on how much bromine is in the unit, the flow rate of the pump etc. Also, bromine can not be stabilized so it's will not remain in the pool for a long time so it will have to be continually circulating.

Why does my current chlorinator run dry and suck air into the system?
 Reply

A  Answered on 5/19/2017 by InyoPools Product Specialist Lennox H.

Hi. Your cholrinator is dry because water is not flowing through the unit. The chlorinator is on the pressure size of the system so it's unable to suck air into the system. The problem is on the suction side of your system. To troubleshoot this issue, follow the steps in out How to Identify and Correct Air Leaks guide.

Hello Joyce- here is a link to the Rainbow 320 Parts Diagram. In the diagram, I would like you to look at 17, 18A, 21, and 22 on the diagram. To access this area, you would need to remove #18A, the locking screw. This will allow you to access the #17 o-ring between the #22 Tee and the tube. You would need to order #17 O-ring, Bottom-Inline (128).

How much pressure is required for this chlorinator. I approached my pool builder about a 2 speed pump so I could run the filter pump / chlorinator just as long but not use as much electricity, and he said the 2 speed pump did not provide enough pressure for the chlorinator?
 Reply

A  Answered on 9/29/2016 by InyoPools Product Specialist Scott W.

Your pool guy is probably concerned with the decreased flow rate which will cause the chlorinator to produce less chlorine than when it is on high. I am guessing he is concerned with your pool turning green due to not enough chlorine being applied to your pool.

I have a Rainbow 320 inline chlorinator on my 14,000 gallon in ground pool with a ozonator. The pool and equipment was installed in 2009. The 320 seems to be working properly; water drains when opens, fills when turned on and the tablets are dissolving etc, but no matter how high I set the feed dial the chlorine is always low. Could there be something plugged that needs servicing?

A  Answered on 4/13/2016 by InyoPools Product Specialist Lennox H.

Hi Pat, A few things that you can check: (1) the Screen on the bottom of the unit (2) the Check Valve. You can also try pouring hot water down the chlorinator, that can clear the lines of any blockage due to chlorine build up.

There could be a number of issues that can cause these tablets to not be dissolving. There could be a pinched hose, clogged chlorinator, or even insufficient flow from an equipment issue.

I recommend refilling the chlorinator if and when the pool chemistry calls for it. If the chlorine level is maintaining a high level then either add less or none until that level lowers a bit. If low then a shock and refill is necessary. If its maintaining a level chlorine reading then yes refill.

What is the difference between an inline and offline chlorinator?
 Reply

A  Answered on 1/30/2012 by InyoPools 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.)

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?
 Reply

A  Answered on 3/10/2007 by InyoPools 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

I wanted to have a inline chlorinator to make things easy.

Written on 1/25/2018 by Guest

I shut down the pump and relieved the pressure on line.Due to it being a chemical I also wanted to install a 2 inch check before the chlorinator.When u do this make sure valve is chemical resistant.After a coupling was used I tied in the chlorinator..Then glued in the last coupling.I let it set and started it up after adding 5 3 inch tabs.I started it on the lowest setting and went up from there.It works great!! I saved nearly300.00 by ordering it from INYO supply.

Thanks guys
Rick
