To prevent airlocks when filling your spa, be sure to open all valves in the JetPaks and all other jets in the spa before filling to allow as much air as possible to escape from the system during the filling process. Fill your spa through the filter by taking the filter cap off and put the hose directly in the filter. Detailed instructions for filling each spa series are found in your owner’s manual. Your hot tub’s pumps must be primed directly after filling to ensure correct operation of your spa and get rid of any airlocks. After initial startup, verify that the home status screen appears on the panel. Depending on your spa model, your spa has either 1,2, or 3 pumps. To prime the pumps, press the “Jets 1” button once to prime in low-speed. After the pump turns on and water is visibly flowing from the jets wait a few seconds and then press “Jets 1” again to initiate highspeed operation of Pump 1. The pump has primed when water is flowing from the jets. If your spa is equipped with a second jet pump, repeat the priming process for Pump 2 by pressing the “Jets 2” button once to turn on low speed and then a second time to turn Pump 2 on high. If your spa has a 3rd pump, press the “Jets 3” button to prime the third jet pump. All pumps will have primed when water is observed flowing from the jets associated with each pump. On rare occasions, priming the pumps will not get rid of an airlock. The next step is to remove the front panel and locate the pump with an airlock. The wet-end of the pump has a bleed valve—loosen this until all the air escapes and water starts to drip out, or loosen the union on the pump to let the air out until you see water. Do not attempt this while the spa pump is running. If you need help doing this or this does not resolve the problem, please contact your authorized Bullfrog Spa Dealer.
