Step 1 Attach a suction hose(1 ½ inch vacuum hose, filter suction hose, or auto vac suction hose) to the end of the CSU with the hose fitting.

Step 2 Carefully lower the CSU into the water being sure that the hose and the CSU fill with water.
Important The CSU is heavy and must be lowered and lifted out of the pool using rope or twine.

Step 3 Insert the other end of the hose directly to the skimmer, or thread a hose adapter into the bottom of the skimmer and attach the end of the hose onto the adapter. This will insure that if the pump is turned off, the hose will remain in place.

Step 4 Adjust the skimmer and main drain valves to achieve optimum water flow. The CSU will restrict water flow through the skimmer.
Important Be sure that the skimmer with the CSU attached, does not starve the pump.

Step 5 Keep the pump and heater running until you have achieved the desired results. This could be from 1 to 7 days depending on the water quality and the surface condition of the pool.

The Crystal Capsule CSU works with all sanitizing systems and filtration systems. The Crystal Capsule CSU is not a replacement for pool chemicals. A sanitizing system must be in place to operate the Crystal Capsule CSU. The Crystal Capsule CSU works best in water temperatures of 65 degrees or more.

Warning: The Crystal Capsule CSU has a strong magnetic field output. Those with pacemakers or other medical devices should not handle this device. Keep a five foot distance between the Crystal Capsule CSU and other electronic and CRT based equipment.
