Winterizing & Storing Your SWIM Spa
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.*
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.
1.
Due to the physical size of the swim spa, we recommend draining your swim spa with
a submersible sump pump. Draining your swim spa with a conventional swim 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 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 swim spa. A non-toxic, RV water line
type antifreeze can be used and added to jets in each seat around your swim spa to help pre-
vent 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 swim spa and
in the equipment area.
8.
Clean the swim spa with a soft cloth and a non-abrasive swim spa surface cleaner.
9.
Replace access panels.
10.
Cover the swim spa to prevent water from entering it and check the swim spa periodically to
be sure no water is entering and accumulating. Swim spa covers are great insulator but will
allow some precipitation to enter the swim spa. For this reason, it is highly advised to also
cover the swim spa with a water tight tarp while winterized. It is beneficial to keep the swim
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 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.
STORING YOUR SWIM SPA
The swim 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 swim spa.
Prolonged, direct sun heat can damage the surfaces of the swim spa along with any components
on the swim spas surface. Always keep the swim spa covered and protected with an insulating
swim spa cover. Resulting damage such as cracking in the shell surface or warped or discolored
components on the swim spa would not be warranted.
An empty swim 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 swim
spa will be exposed to these temperatures, keep the unit filled and running. If you do not plan to
use your swim spa, you can set the swim spa to the lowest temperature setting allowed by the
control system.
Failure to adhere to these guidelines may result in unwarranted damage caused to the spa.
