It’s finally starting to feel like Spring is really here! If you were foolish enough to close down your hot tub for the winter months and missed enjoying the lovely winter season from your hot tub, you are probably anxious to get back into your spa now.

If you followed our winterizing procedures, then your spa should have been protected all winter long from damage and is now ready for Spring Start Up. Follow these simple steps to get your spa ready for the summer months ahead!

Steps Before You Fill

Before you refill your spa with water, you need to inspect it to ensure that it is ready to be refilled and powered up.

  1. Remove any debris in and around the spa and wipe the shell surface clean with a damp sponge. Be careful not to scratch the surface with any particles that may have falled into the tub
  2. Make sure that the “T” valves on each water pump are open by pulling them up as far as they will go. Each water pump has two “T” valves that are located on either side of it. Both “T” valves on every pump must be open to enable air and water to flow through the spas internal pipes.
  3. Tighten all water pump and heater unions.
  4. Check all drain plugs located on each water pump to make certain they are closed
  5. Make sure the hose spigot on the water pump is closed by turning it clockwise until it is tight. The hose spigot is lcoated on the primary water pump
  6. Make sure all filters are in place
  7. Always be sure to check your water source for soft water or a high mineral content before filling your spa.
  8. If your home has a water softener, bypass it.
  9. Let the water run out of the garden hose for several minutes before filling the spa. They will flush out stagnant water in the line that may cause bacteria.

Initial Start Up of Your Spa

It’s now time to fill and start your spa. Most people fill their spa with a garden hose. Occasionally people with well water or water with a high mineral content have water delivered, but this is not usually necessary. 

  1. Begin by filling your spa after following the steps above. Fill the spa to the recommended level: at least 2″ above the filter inlet and approximately 6″ below the spa rim.
  2. Once your spa is sufficiently filled, turn on the spa’s main circuit breaker (after reading all warnings.)
  3. Turn on the water pump(s).
  4. Once the water pumps are operating, set the digital thermostat control between 100 F and 104 F. (Do not exceed 104 F).
  5. Shut off the therapy control valve that controls the jets to the filtration pump. This will save heating costs, along with helping you to keep bacteria out of the water when the hot tub is not in use.
  6. Install and secure the insulated cover.
  7. Allow between 5 and 24 hours for the water to reach your desired temperature.
  8. Treat the water with chemicals, performing the start up procedural for your preferred sanitation method found in your Owners Manual.
