Winterizing & Storing Your Spa - Master Spas SEATTLE Owner's Manual & Limited Warranty

WINTERIZING & STORING YOUR SPA
WINTERIZING YOUR SPA
Your spa is designed to be used year round in any type of climate.
However, if you decide you don't want to use your spa in the winter, you must drain it
and follow the winterizing steps listed below.*
DISCLAIMER: Master Spas does not recommend winterizing your spa. If you choose to do so,
any damage that may result is not covered under the spa warranty.
1.
Drain your spa completely using the drain valve (if so equipped) or use an inexpensive
submersible pump that you can buy from your local hardware store.
2. Use a shop vac to get all standing water out of your unit.
3.
Remove access panels from equipment area.
4.
Loosen all pump unions.
5. Remove winterizing plug from face of the pump(s) where applicable.
6. Using your shop vac in a blowing mode, insert the hose into the nozzle of each jet and blow
the trapped water from the lines into the interior of the spa. A non-toxic, RV water line type
antifreeze can be used and added to jets in each seat around your spa to help prevent freeze
damage from occurring. Be sure to thoroughly flush the system before startup.
7.
After this is completed, use the shop vac to remove any standing water in the spa and in the
equipment area.
8. Clean the spa with a soft cloth and a non-abrasive spa surface cleaner.
9.
Replace access panels.
10. Cover the spa to prevent water from entering it and check the spa periodically to be sure
no water is entering and accumulating. Spa covers are a great insulator but will allow some
precipitation to enter the spa. For this reason, it is highly advised to also cover the spa with
a water tight tarp while winterized. It is beneficial to keep the spa cover slightly gapped off
the acrylic shell while winterized to allow air flow in to the shell area to reduce mildew/mold
buildup caused by trapped moisture.
* If you decide to winterize your spa, we recommend that you periodically check the spa
throughout the winter to assure water is not entering the spa through or around the spa cover.
STORING YOUR SPA
The spa shell should never be left unprotected and uninsulated while being stored. Clear plastic
wrap or similar material should never be used to cover/protect the spa.
Prolonged, direct sun heat can damage the surfaces of the spa along with any components on the
spa's surface. Always keep the spa covered and protected with an insulating spa cover. Resulting
damage such as cracking in the shell surface, warping or discolored components on the spa would
not be warranted.
An empty spa should never be exposed to temperatures below 0°F (-18°C) after delivery as
extreme cold can cause shell damage. This includes storage and draining (winterizing). If your spa
will be exposed to these temperatures, keep the unit filled and running. If you do not plan to use
your spa, you can set the spa to the lowest temperature setting allowed by the control system
while in Standard/Ready Mode.
Failure to adhere to these guidelines may result in unwarranted damage caused to the spa.
