2013 Michael Phelps Swim Spa RX Owner's Manual - Master Spas

Winterizing Your Spa
1. Due to the physical size of the spa, we recommend draining your spa with
a submersible sump pump. Draining your spa with a conventional spa drain
is not a reasonable option in some cases.
2. Loosen all pump unions
3. Remove winterizing plug from face of the pump(s) where applicable.
4. 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.
5. Connect a hose to the manifold drains located on the step side of the unit to drain manifolds.
6. After this is completed, use the shop vac to remove any standing water in the spa and in
the equipment area.
7. Clean the spa with a soft cloth and a non-abrasive spa surface cleaner.
8. Replace access panels.
9. Cover spa to prevent water from entering the vessel.
* If you decide to winterize your spa, we recommend that you periodically check the unit
throughout the winter to assure water is not entering through or around the cover.
