OPERATION & TROUBLESHOOTING
Operation: Cleaner Movement
While observing the MX8 Cleaner, it is crucial to understand that each cleaner has a dynamic, or unique pattern created by the Directional Control Devices (DCDs). The following shows the timing of the DCDs. 1- The cleaner timing cycle repeats approximately every 30 minutes. 2- There are 12 long runs of between 30 and 40 seconds.
3- There are 5 full reverses of approximately 4, 5, 6, 9, and 15 seconds. (Not in that order). 4- There are 5 overlapping turns that will produce short duration full reverses of about 1 to 2 seconds.
Troubleshooting: 1- Clean skimmer(s), filter pump basket, and filter. 2- Confirm returns are facing down to the pool bottom 3- Confirm proper installation: • Main Drain Closed • Hose Length & Float Location are correct • Pool Connection is tight • Flow (use Flow Gauge to confirm) • Cleaner Connection. 4- Check for debris jammed in the engine. 5- Check for air in the system by looking at the pump basket while running. If there is a drop in the water level, or excessive bubbles are present, there maybe an air leak. Check hose connections, tighten all fittings and check o-ring at the pump. Note: In some pools where the cleaner either doesn’t climb the walls or it comes out of the pool, the flow may need to be adjusted from the factory recommendations. First confirm proper float location and adjusting the flow as needed by watching the cleaner movement for 5 to 10 minutes.
