12. Remove jet faces and insert the hose of a high-pressure air blower into each jet fitting. Continue this process,
until no more water comes out of any jet fitting or drain fitting, and you no longer hear water gurgling within
the plumbing. Place all jet faces in a plastic bag and set aside until you are ready to use your spa again.
13. Remove both bleeder valves from the top of the filter canister area. Place hose of a high-pressure air blower into
the rear-most bleeder fitting first. Confirm that water mist is blowing from one or both of the circulation system
return jets in the footwell of the system. You may also get some water mist blowing from the filter canister.
Repeat this process with the front-most bleeder fitting. Confirm that water mist is blowing from the drain
fittings of the jet pumps.
14. Place the hose of a commercial grade, wet-vacuum over each jet fitting, bleeder valve fitting, and drain fitting to
draw out as much remaining standing water as possible.
15. Remove drain hose bib assembly from the outside bottom of the system.
16. Use the wet-vacuum to remove standing water from the pumps and any other fittings within the equipment
compartment.
17. Once you are sure that all water is evacuated from the plumbing and equipment of the system, put the system
back down in its normal position and repeat Step 10 and Step 11
18. Read all Directions and Safety Precautions on the Swimming Pool or Recreational Vehicle antifreeze bottle
before opening and using. Ensure that it is non-toxic and safe for this use. Beware of and follow all safety
precautions.
19. Using a long funnel, begin pouring non-toxic swimming pool or recreational vehicle water system antifreeze
into the filter canister fittings, bleeder valve fittings and jet fittings of your system. Continue adding antifreeze
until it comes out of the drain fittings or from the opening you are pouring it into. You must complete this task
for every jet fitting in the system. Some of the antifreeze will seep into the system from the drain or jet fittings,
which is okay, the goal is to have anti-freeze collect in the areas of the plumbing that would normally trap
water. Use the funnel to also place antifreeze into the pump housing(s).
When pouring antifreeze into the rear-most bleeder valve fitting, you may see antifreeze pouring
from one or both of the circulation system return fittings. This is okay.
DO NOT USE AUTOMOTIVE COOLING SYSTEM ANTIFREEZE IN YOUR SYSTEM. IT IS
TOXIC AND HARMFUL TO HUMANS AND ANIMALS. CHECK WITH YOUR LOCAL SPA
DEALER OR RV DEALER TO PURCHASE
NON_TOXIC ANTIFREEZE THAT IS
COMPATIBLE WITH DRINKING WATER SYSTEMS!
20. Replace all equipment access panels onto the system.
21. Replace thermal cover and secure locking tabs. If your system is located in an area of high snowfall, you may
want to take one more extra precaution to safeguard the life of your system cover. Span the cover with (2 or
more) 2x4’s cut to length to reach the outside edges of your cover. Place a sheet of plywood, cut to fit each half
of the cover, over the 2x4’s; this will support the load of a heavy snowfall and prevent the cover from warping
or breaking. You can also cover the entire system with a tarp at this point for maximum protection.
Springtime Startup of a Winterized Spa
In the spring, or when you are ready to restart a Winterized spa, follow these instructions:
• Make sure o-rings for pumps are in place and undamaged.
• Make sure all the fittings that loosened are re-tightened.
• Replace all jet fittings, pump drain plugs, hose bib drains, and bleeder valves
• Fill the system up, as you would normally do.
• Turn the power back on.
• Run the jets on high speed for about 15 minutes.
• Drain the water.
