Jacuzzi JPDS Auto Descaler
How the Unit Works
Once the unit has been installed correctly on the pool circulation system, the Jacuzzi
JPDS Auto Descaler will pass a radio signal into the water. This causes the calcium
ions 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 will
disappear with it. Some silica scale may reappear, though considerably less than
before.
NOTE: Silica scale which has been leached from behind the tiles will not necessarily
be reduced.
Installation Tips
Follow these three essential points for proper installation:
1. Wires must be tight on the PVC pipe and secured at both ends by the provided UV
rated plastic zip ties.
TIP: Vibrations from the pump may cause the wires to come loose. Check the wires
occasionally to retighten.
2. Keep the Descaler control box close to the pipe so you have the maximum
amount 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 the
aerials.
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 on
recirculating systems for swimming pools. The Jacuzzi JPDS is fully waterproof and
can be exposed to rain and harsh weather.
The antennas and power supply are directly wired into the control box and cannot
be 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 power
supply connection.
