Winterizing Procedures for Hot Tubs

NOTES: Arctic and Coyote spas are all designed to be run year round.
This is the factory winterizing procedure for northern Canada; your dealer may recommend a different method based on local experience.

You may have complications with the spa when you try to restart in the spring, and having your dealer do both the winterizing and the spring startup is the best way to protect your spa and your warranty.

It will take approximately 4 to 6 liters (1 to 1.5 gallon) of RV antifreeze, depending on the model of the tub. A funnel with a flexible spout will give best results.

1. Remove as much of the water in the spa as possible.
2. Remove all of the unions off of the pumps and heaters to allow all of the water to drain out.
3. Us a wet/dry vac to remove as much of the water as possible out of the jets and lines. Remove the filter and suck out any water in the cannister.
4. Reattach the unions to the pumps and heaters.
5. Remove the diverter valves and pour approximately 500 ml (16 oz) of RV antifreeze down each position of the diverter (left, center, right).
6. If you have a waterfall, remove the control handle and pour 500 ml down the line. (Note: there is a special procedure for correct reinstallation of the waterfall valves. Ask your dealer for Information Bulletin 145).
7. Using a small funnel, put a few milliliters (1 tbsp) of antifreeze down each of the jet lines.
8. Make sure to get some antifreeze into the pumps and heater as well.
9. Pour approximately one liter of antifreeze into the filter cannister.
10. If you have a Peak Ozone system, remove the large fitting at the top of the stainless steel mixing chamber and get as much water out as possible. Pour some antifreeze into the Static mixing chamber. Add antifreeze until the chamber is full or until antifreeze begins flowing out of the peak jet into the bottom of the tub.
11. Remove the wetend off of the circ pump and leave disconnected.
12. Make sure that all lines have some antifreeze in them.
