Typically jets are placed on the rear wall of the pool just above the seat. The jets can be either clustered together or located remotely from one another. Because personal preference will vary, a good way to select location is to sit in a chair and measure from the seating surface to where the jet would be most comfortable on your back. This will give you the vertical distance from the base of the bench to the desired jet location. If the jets are to be vertically aligned, the distance from center point to center point must be a minimum of 10. The top jet has to be a minimum of 11 from the top of the pool. The two jet suctions need to be 3 apart (from center point to center point). We have provided a diagram for placing the suction holes at the front of the pool with the rest of your equipment. The 3/4hp, 220v jet pump needs to be installed in the cavity created for the Water Quality System at the front of the pool, since it will receive its electrical supply from the heater controller. The electrical cord, which is pre-wired to the pump, plugs into port P1 (orange) on the heater controller. Please remember that drainage for the Water Quality System cavity is required. Important notice: If your pool or equipment will be subjected to freezing temperatures, special consideration must be given to the jet system in order to avoid freezing of the plumbing lines. Your heater/controller is programmed to automatically circulate the jet plumbing lines four times a day. This circulation reduces the likelihood that the plumbing lines will freeze. Once your pool s installation is complete and the pool is in an enclosed space, additional insulation of the siding material will help keep the warm air radiating from your pool in the enclosed space, which is where both your jet pump and jet plumbing lines are located. Having your jet plumbing line run within the space immediately adjacent of the pool is necessary for proper protection from freezing. Additionally, the heater controller comes equipped with a smart winter mode (SWM). When the SWM is enabled, the system will automatically turn the pump on to ensure that there is warm water moving through the plumbing lines. Please see the Water Quality for more information on this feature. If you believe that these measures will be insufficient to prevent your jet plumbing lines from freezing, please call our Customer Service Department.

After the holes have been drilled, sand or grind the backside of the pool flat, and apply a small amount of silicone to the exposed edge of the hole. Again, the placement of the two suction holes need to be considered. They have to be 3 apart (from center point to center point), a minimum of 12 up from the floor of the pool, and a minimum of 12 away from the corner. These suction fittings should be placed at the front of the pool. 2. Install each thru-wall fitting so that there is a rubber gasket between the fitting and the inside of the pool wall. The second rubber gasket will not be used in this application. The cork gasket will be used on the backside of the pool wall. Make sure to use silicone sealant on both sides of the pool wall. 3. Remove the protective strainer from the suction fitting. Add Teflon sealant onto the thread of each and attach a female slip x female pipe thread union onto each adapter. Next glue a male slip x female slip 90º elbow into each union so that they are facing each other. These two suction lines need to be connected before the suction line goes back to the pump. Ideally, the tee should be centered between the two suction fittings. Once the jet suction fittings are installed, the fitting can be plugged from inside the pool with a #10 wing nut plug until all of the jet plumbing is complete. 4. Cut lengths of the 1/2" PVC pipe for the air supply to each jet. The air pipes for the lower jets may require elbows to clear the jets and piping above. Once installed, the open top of the air supply must be above the water line to prevent spill over. The pipe should be terminated 1/4" below the top flange of the pool. The 1/2" air supply tubes should be cemented to the jet bodies first, in an inverted position, with the jet internals removed, to prevent dripping of PVC cement or cleaner into the air passages. If you intend to install your pool fully in-ground, then the 1/2 air pipe installation will not be appropriate. Instead, glue the plug into the 1/2 opening in the top of the jet body. Then connect the 1 1 / 2 air openings with 1 1 / 2 pipe and run this one large air-line back to the front of the pool so that it terminates in the cavity that was created for your water quality system. Make sure that the end of this air pipe is positioned above the water line in the pool. 5. For your four jet fittings, place the white gasket between the bulkhead fitting and the pool wall. The clear gasket provided will not be used in this application. Apply a bead of silicone sealant on the backside of the pool wall around the perimeter of the hole where contact will be made with the face of the jet body (The portion of the jet fitting that receives the plumbing). Press the jet body with air tube installed against the pool wall, aligning with the drilled hole. 6. Apply Teflon sealant completely around the threaded barrel of the jet bulkhead. Screw the jet bulkhead with the gasket and Teflon into the corresponding jet body. Repeat this procedure for each of the three remaining jets. A jet tool has been included in your kit to help with the tightening of the jet bulkheads. Note: Be sure not to cross-thread the jet bulkhead as it will not seat properly. 7. Cut lengths of the 1 1 / 2 " PVC pipe provided to connect to each of the four jets. Three 1 1 / 2 " tees and one elbow should be fabricated to provide a supply piping manifold to coincide with the four jet locations. From each of these four fittings extends 1 1 / 2 " PVC to a union. From the unions, connect to each jet with 1 1 / 2 " PVC and an elbow (lower jets use male slip-female slip street elbows, upper jets use a nipple cut to length and a female slip-female slip elbow). The side of each jet opposite where the supply is connected at the bottom will require a plug. The unions allow each jet to be installed separately either before or after the supply piping manifold is assembled. 8. Cement all PVC slip connections following the cement manufacturer's recommendations. 9. Check the 1/2" air supply pipes to make certain that all four are 1/4 below the top flange of the pool wall. Extend or cut these tubes as required. 10. With the four jets and the suction fittings installed, the ball valves and remaining piping back to the jet pump can be installed. Union fittings have been provided on each side of the jet pump to facilitate its removal should service ever be required. The pump will come with the electrical cord pre-wired. The pump should be placed into the Water Quality System cavity close enough to the heater controller so that it can be plugged in. The clearance behind finish skirting should be considered when plumbing the jet pump.

3 Page 3 of The jets can be turned on by pressing the pump button on the keypad once then, press it a second time to turn off the jets. Before operating the hydrotherapy jets, make certain that both ball valves are open and the threaded plug in the suction fitting has been removed. The protective suction strainer should now be reinstalled at this time. It is extremely important that strainer be screwed into the suction fitting assembly.
