The Fill & Start-Up Process
Fill & Start your Strong Spa in 9 easy steps.
Prep Your Foundation
Place the spa on an approved surface and have it properly wired by a licensed electrician.
Remove Exterior Panels
For DURA-LAST™ models, remove exterior spa panels by inserting a flathead screwdriver at bottom edge of the panel and prying it out. For ULTRA-TEC models, remove screws that hold the side panels in place. For Durasport models, unlock and open the access door.
Check the Unions
Make sure white plumbing unions are secure and did not loosen during shipping. There will be 4 unions on a 1-pump spa and 6 unions on a 2-pump spa. Hand-tighten any loose unions.
Open the Gate Valves
Open all gate valves in the equipment area. Before operation, these valves must be in the UP/OPEN position and have plastic clips inserted. Never run the spa with the gate valves closed or without water circulating for any period of time.
Remove the Filters
Remove the filter(s) (and weir and basket, if equipped) from the filter chamber.
Fill Your Spa
Fill with a garden hose using cold water through the filter canister, preventing airlock, until 2 inches above the highest back jet (not neck jet).
Power On the GFCI
Once the water is at the correct level and air is bled, turn on the power at the GFCI breaker. When the power is turned on, the controls will per¬form a diagnostic check for a few minutes. When complete, the spa will automatically operate at filter speed and continue heating until water reaches desired temperature.
Check the Pumps
If water does not flow from the jets when the pump is running, there could be an air pocket. See the “Priming the Pump” section below for methods of removing air pockets from the pump(s).
Install The Filters
Install the filter(s) (and weir and basket, if equipped) into the filter chamber.
Priming Your Spa's Pump
Sometimes air can become trapped in the pump while filling the hot tub. You will know this has happened when after filling and starting the spa, the pump does not function. You will hear the pump operating, but no water will be moving. DO NOT continue to operate the pump this way or it will cause damage to the spa.
Priming your pump for the first time can be frustrating, but these simple instructions can help you.
Removing Trapped Air Bubbles and Pockets
Turn the spa on and wait for PR (Priming Mode) to appear on the topside display.
Press the JETS1 button to turn on the pump, then let it run for 10 seconds. The pump should be running on low speed.
Press the JETS1 buttons again and let the pump run on high speed for 10 seconds.
Press the JETS1 button again to turn off the pump. The pump should be left in the off position for 10 to 15 seconds.
Repeat steps 1 through 4 until water is flowing through all the jets and all the air is removed from the plumbing.
Removing a Large Air Lock in your Pump
Turn the spa on and wait for PR (Priming Mode) to appear on the topside display.
Turn off power at the breaker.
Remove the hot tub panel closest to the pump.
Loosen the white pressure union on the top of the pump by hand or with a strap wrench. When air is bled out, tighten the union, turn the breaker on and set the pump on high speed. NOTE: If you press the “Temp” button any time during Priming Mode, it will exit that mode and begin Standard Mode.
