Chemical treatment instructions are based on pools that are approximately 100,000 L; for large or small pools please adjust accordingly. Treatments should begin the week before closing, and with your filtration system running.
One of the last steps of winterizing is freeze proofing all of your pool equipment including your: pump, filter, heater, chlorine or salt system, skimmer and heater. These items all need to be drained of any water. Plugs, pressure gauges, pumps, skimmer baskets and return fitting eyeballs should also be removed and stored in one place so that you don’t lose them.
All plumbing lines need to be blown out with an air blower to ensure that all water is removed (both skimmer and return lines). The skimmer, return and suction lines need to be plugged and/or sealed using winter plug kits and gizzmos for the skimmer.
Filter & Pump
Next, you’ll need to set and leave the pointer on the filter dial valve to the winterize position; if your valve does not have this feature set the pointer between any two positions. For cartridge filters, open the air release valve on the top of the filter followed by removing and storing the drain cap at the base of the filter tank, the pressure gauge and site glass (if applicable). Next, you’ll remove and store the drain plugs from the wet end of the pump. Please ensure that all of the water is drained from both the filter and the pump.
Inground and onground lights should be weighted, placed in a bag and lowered into the pool. Above ground lights should be removed for storage and the resulting opening in the pool wall should be closed with a rubber expansion plug.
First, you will turn off the main gas supply valve to the heater that is found outside the heater jacket. Next, you’ll shut down your heater with the shutdown instructions found on the inside of it. Remove the drain plugs from the return side header, loosen the drain plug from the inlet/outlet side header, and completely drain the heater. You’ll need to use compressed air to blow out any outstanding water remaining in the heat exchanger. Grease the threads on your drain plugs and reinstall your plugs but remember to not tighten them. In addition, please disconnect the pressure switch from the siphon tube (copper tubing).
Remember! Your heater must be completely drained prior to the first frost. Serious damage may occur if any water freezes inside your heater and piping.
Inground & Onground
First, you’ll need to remove and store your basket and floating weir. Insert about 3 feet of foam rope down the hole into the bottom of your skimmer, doubling the top end onto itself for easy removal in the spring; you can also add pool antifreeze as per the manufacturer’s instructions as well. You will then thread a gizzmo into this same opening. If your pool has two unplugged openings, in the bottom of your skimmer you’ll need to install foam rope and a gizzmo into the rear hole, and foam rope and a winterizing plug in the forward hole.
If you own an above ground pool, you’ll need to remove and store the basket and floating weir. Next, please disconnect your hoses from the skimmer and from the return wall fitting. Leave the hole at the bottom of your skimmer open and disconnect the pipe from the front of the pump to prevent ice damage.
Salt Water Generators
Zodiac LM Series
You will need to start by turning off the power to your salt system. Next, you will remove the cell by unthreading the quick-disconnect unions and removing the three lead wires from cell. Inspect the cell and clean it if necessary; please refer to your owner’s manual for cleaning instructions. Coil the wires and wrap them in a plastic bag to prevent corrosion over the winter; for convenience tape the bag to the power back. Insert expandable plugs into the upright plumbing lines where the cell was connected and store the cell indoors; the power pack can remain outdoors for the winter.
Zodiac Duo Clear Series
First you’ll want to turn off the power and disconnect the electrode plug. Coil the electrode cord and wrap it in a plastic bag; tape the bag to the power back for convenience. If your vessel is installed with unions you’ll need to unscrew the unions, remove and store the vessel, seal your exposed pipes with the expandable plugs and discard the used Nature2 cartridge. If your vessel is glued to the pipe, you’ll need to leave the vessel on the line for the winter. In addition, you’ll have to leave the cartridge and electrode inside the vessel for the winter.
Fusion Soft Series
Remove the Nature2 cartridge, place the temporary cap in place and tighten down the collar first. Next, carefully remove any remaining chlorine tablets; be sure to wear protective skin and eye wear. Replace your empty chlorine holder into the unit, retighten the collar and run the pump for 30 minutes to remove any remaining chlorine tablets. Remove and store the drain plug, rinse out your Nature2 Fusion thoroughly with water and blow your lines clear with air. Please ensure that your chlorine regulator dial is set to 5 while doing this. After you complete your Fusion Soft Series winterization, loosen the collars.
Automatic Chlorinator/Brominator Dispensers
In Line Permanently Installed
You will need to remove your cover and drain the plug in order to make sure that all of the water from your chlorinator is gone. Carefully remove undissolved tablets, rinse out your chlorinator thoroughly and replace the cover with your drain plug.
To start, remove your cover while carefully removing any undissolved tablets. Disconnect your unit at the inlet and outlet followed by turning it upside down for several minutes in order to remove any excess water. Once all of the water is out, you may re-install your unit. Please remember that this remaining water is concentrated chlorine; use extra caution here.
