Jacuzzi JPDS Quick Start Manual

Jacuzzi JPDS Auto DescalerHow the Unit WorksOnce the unit has been installed correctly on the pool circulation system, the JacuzziJPDS Auto Descaler will pass a radio signal into the water. This causes the calciumions to precipitate in suspension in the water, instead of on the surface of the pool.Existing scale will be removed over the course of a few weeks, and any staining willdisappear with it. Some silica scale may reappear, though considerably less thanbefore.NOTE: Silica scale which has been leached from behind the tiles will not necessarilybe reduced.Installation TipsFollow these three essential points for proper installation:1. Wires must be tight on the PVC pipe and secured at both ends by the provided UVrated plastic zip ties.TIP: Vibrations from the pump may cause the wires to come loose. Check the wiresoccasionally to retighten.2. Keep the Descaler control box close to the pipe so you have the maximumamount of wire available to wrap round the pipe.TIP: Secure the box directly to the PVC pipe or simply let it hang just below from theaerials.3. Install the auto Descaler on a horizontal pipe on the discharge side of the pump,preferably immediately after it and before the filter.This product is intended for use on plastic PVC pipe up to 2.5” diameter onrecirculating systems for swimming pools. The Jacuzzi JPDS is fully waterproof andcan be exposed to rain and harsh weather.The antennas and power supply are directly wired into the control box and cannotbe removed from the unit. The circuit board is fully encapsulated in epoxy resin.Enclosed you will find a plastic sheath which can be heat-shrunk onto the powersupply connection.
