Your model’s manual comes first
Start with the current owner’s manual for your exact spa model and a qualified spa service professional. Ask Hot Tub Wholesaler to help identify your model and the correct manual before draining, winterizing or reopening your spa.
The linked Strong shared manual is the manufacturer’s current revision. Confirm that it covers your spa’s model, build year and installed equipment; it is not a verified exact-model manual for every Strong spa or a universal procedure for older models. Follow the applicable instructions for ongoing cold-weather operation, seasonal shutdown, reopening and warranty coverage.

Seashore pool, pump and filter

A retailer-hosted installation PDF has not been verified as an exact match for this package. Pump horsepower and filter size alone are not enough to select equipment manuals.
Historical reference: original draining & winterizing steps
The original numbered steps and drain-location notes below are preserved for historical reference. They are not current model-specific instructions. Follow the current manual for your exact spa and consult a qualified spa service professional.
Historical draining instructions
- Turn off the power at the breaker.
- Remove all filters.
- Using a Phillips screwdriver, remove the screws to the access panel and open it.
- Locate hose ending with the 3/4 inch hose-bib fixture.
- Hook up the female end of a garden hose to the drain fitting.
- Place the other end of the garden hose where you would like the water to drain to.
- Twist the hose-bib fixture counterclockwise and pull to open the drain.
- Let spa drain completely, then remove garden hose.
- Twist the hose-bib fixture clockwise to close it.
Historical winterizing instructions
Historical reference only. These original steps are incomplete for current Strong 230/240V hardwired spas and must not be used as a current procedure.
- Open all filter covers.
- Remove the filter baskets and filters.
- Drain your spa completely as described in the instructions above.
- Remove drain plugs from the front of the pumps.
- Disconnect the unions from both sides of the pump.
- Use a wet/dry vacuum to blow any remaining water out of the jets and equipment area.
Cover your spa with a good spa cover and an all-weather tarp to ensure that neither rain nor snow enters the spa.
