WINTERIZING YOUR SWIM SPA
Your swim spa is designed to be used year round in any type of climate.
*However, if you decide you don’t want to use your swim spa in the winter,
you must drain it and follow the winterizing steps listed below:
1.) Due to the physical size of the swim spa, we recommend draining your swim
spa with a submersable sump pump. Draining your swim spa with a
conventional spa drain is not a reasonable option.
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 the face of the pump(s).
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
swim spa.
7.) After this is completed, use the shop vac to remove any standing water in the
swim spa and in the equipment area.
8.) Clean the swim spa with a soft cloth and a non-abrasive spa surface cleaner.
9.) Replace access panels.
10.) Cover swim spa to prevent water from entering the swim spa.
*If you decide to winterize your swim spa, we recommend that you periodically
check the swim spa throughout the winter to assure water is not entering the
swim spa through or around the swim spa cover.
*Disclaimer: Master Spas does not recommend winterizing your swim spa. If you choose to
do so, any damage that may result is not covered under the swim spa warranty.
