How to use and maintain your Oasis Spa with Spa Tech Controller


Congratulations on the purchase of your new oasis spa. We want to help you get the most from your spa right from the start, by understanding how to set it up, operate the controls, manage the water and look after your investment.

We’ll break this into easy segments:

  • Filling your spa
  • Setting up the control system
  • Turning on the jets and bubbles
  • Adjusting the massage jets
  • Water maintenance
  • Jet maintenance
  • Cleaning your filters
  • Cleaning your cabinet and spa cover
  • Draining your spa
  • Fixing air locks
  • And cleaning water diverters and massage controls

Once you’ve unwrapped you new spa and removed the tape from the filter lid, filter face and anywhere else, it’s time to fill up your spa. Remove the filter face by sliding the cover up and then off. Remove the filter or the left-hand filter with dual filter spas. Then place your hose where the filter was and fill to the line shown on the sticker inside your spa. Now you can turn on your spa at the power point or isolation switch.

The spa will start itself up and begin filtering and heating your spa until it reaches the factory set temperature of 38 degrees. It will also begin filtering the water based on the factory settings. If your touch-pad is not illuminated, you’ll need first to wake it up by pushing the power button. Now set the time and adjust the temperature. The time can be set by pushing the time button then the mode button, use the warm or cool buttons to change the time and the mode button to confirm each setting. To set the filter times press the time button once, then the mode button three times, then set the start and end times of each of the two filter periods. Using the warm or cool buttons followed by the mode button to confirm your settings. 2 hours per filter period is suggested, but this can be increased in times of heavy use. The temperature can be set pushing either the warm or cool buttons. Then once the temperature is flashing, use the up and down buttons to select the new desired temperature. If you don’t want people using your spa or changing settings, you can lock the control panel by pushing the warm and cool buttons at the same time, unlock by pushing the same buttons again. You can invert the display panel also, by pushing the time and warm button at the same time, and to swap it back, push them again. There are other non essential settings and features that also may be of interest, and these are explained in your manual and on the DVD supplied in your spa warranty kit.

In spas with one jet pump, turn on your jets by using the Jet 1 button. If you have a two speed pump, press the button once and the pump will come on at high speed, and then after 5 seconds it will drop back to low speed. Press the button a second time for high speed. The Jets 2 button will not do anything. If you have a two pump spa, pressing the Jets 1 button will turn on your first jet pump, this powers half of the jets. The Jets 2 button turns the second jet pump on and powers the rest of the jets. The air jets can be turned on by pressing the blower button. If you turn any pumps or bubbles on, they’ll always turn themselves back off after 30 minutes. To turn your lights on, press the light button, press it again and the lights turn off.  Additional presses will turn the lights back on but with a different colour or effect. The mode button will allow you choose various modes. To move between modes, use the warm or cool buttons, and then press the mode button again to set that mode. Standard mode allows the spa to heat whenever it wants to always maintain you set temperature. Economy mode only allows the spa to heat during filtration times, and then there’s the sleep mode, where the spa will filter but not heat. After you’ve selected the mode you want, push the mode button again to lock in your choice.

To keep your water clean and clear, you need to do four things:

1. Keep the PH at the correct level:

If your water has a low PH level, it will be acidic. While it will be crystal clear, it will be uncomfortable to relax in and can damage your equipment. High PH allows calcium to come out of the solution and make the water cloudy. For water clarity, your comfort and equipment life, make sure you keep your PH level between 7.4 and 7.6. Take the reading, and if it’s outside of this range adjust it as directed on the bottle. Make sure to test the PH first as you’ll get false readings if you test after adding other chemicals. If necessary, adjust the PH using Alkalinity Increaser or PH Decreaser.

2. Sanitise the water:

Do this by adding an approved product as recommended by your Oasis dealer. Make sure the filtration pump is running and add the correct dose to the middle of the spa. Make sure to keep the correct level of sanitizer in the water. And remember if you’re using the spa more frequently, you need to add more sanitizer. If you use it less, you should back off the dosage.

3. Shock or Oxidize the water regularly to remove body oils, makeup, sun tan lotion and organic waste:

Failure to do this can make the water cloudy with oily bubbles on the surface. If you’re using the spa more, you’ll need to shock treat the water more often.

4. Ensure adequate filtration:

Filtration is essential to remove particles and organic materials from the water. It’s a good idea to add extra filtration after each use, by pushing the sanitize button on your Spa-Net SV control panel or push the Pump button on Spa-Tech ST control panels. Even more importantly, remember to keep your filters clean as body oils, makeup and sun tan lotion will clog the cartridges and make the water go bad very quickly. Dirty filters are also a breeding ground for bacteria that will make the water quality even worse.

While our jets are self-cleaning, will rarely clog or stop spinning, it is necessary to regularly remove and check the jets, for any grit or oils on the rear of the jet insert or thread. If this isn’t done, they can be hard to turn on or off, and to remove. To get a better grip on the jet face, try using gloves or a special grip cloth. If they’re really stuck, you may have to do this when the spa is empty. Once removed, wash out the housing and use an old toothbrush to get any grit out from the thread. To clean your filters, turn the spa off, remove the filter face and unscrew the filters. Spray the filter of if it has any visible debris and place it in a bucket with a filter cleaner. Ideally let it soak overnight, then rinse well with an adjustable spray nozzle. If you have a spare set of filters, you can use one set while soaking the other set, and not have any time without filters in your spa. If your cabinet is dirty, you can simply clean it with warm water and a mild detergent. If your cover is dirty, then clean that too with mild detergent. Then treat it with a product you can find at all good spa shops, Aerospace 303, don’t use Armor All. After really heavy use, from time to time when you’re finding it harder to maintain your water quality, you should drain your spa. Use the drain fitting at the base of the spa and the attachment supplied in your warranty pack. Remove the cap, attach the nozzle, click on your hose. Twist the base of the fitting anti-clockwise and pull on the hose to start the flow. The water will flow through the hose and can be directed where you want. When you drain your spa, make sure you always refill it by placing the hose in the filter box as shown earlier. Otherwise you can get an airlock in the plumbing system. There’ll be no water in the heater and you’ll get an error message on the touch-pad. You can try pushing the filtration pump button or pump 1 for spas with 2 speed pumps, on and off to try and get the water flowing. If this doesn’t work, you’ll have to remove the cabinet panel underneath the touch-pad, and unscrew one of the barrel unions on the pump, you’ll hear the air escaping and see the water start to leak from the union. Re-tighten it, and try the pump again. Now it should work. Your massage controls, often referred to as water diverters, make it very hard to move due to sand, grit and body oils getting into the body of the diverter. If this happens, it’s important to turn the spa off first to protect your safety. Next, unscrew the base of the diverter by twisting anti-clockwise. There’s no need to remove the handle. Wipe or wash out the body of the diverter to remove the grit. If the body of the diverter is badly scratched, use fine sandpaper to make it smooth again. You can use detergent or methylated spirits to remove any oily or sticky marks. Then insert the handle or diverter mechanism, and screw the base back on. If you have any other questions regarding the maintenance and use of your Oasis spa, please call the retailer where you bought your spa. Congratulations on choosing Oasis spas. With just a little care, your spa will bring you years and years of pampering and true relaxation.
