Pool 2000 Dosing Pump Features
The Pool-2000 dosing pump is a microprocessor-controlled, clock-based chemical injection pump for accurate dosing of the COVERfree liquid.

The Pool-2000 has a real-time clock, and keeps track of which day of the week it is, so it can dose daily during certain times of the day, and is programmable for independent dates/times. [i.e. 7 day clock, 1 event per hour and all events can be different, absent or programmed to be the same].

For example, it can provide regular doses throughout the week and extra doses during high bather-load times such as weekend nights in a spa, or weekend days in a pool. Need to add extra doses Saturday afternoon or evening? No problem for Pool- 2000, just 10 seconds of programming will let you add an extra pump event for Saturdays, etc. In addition, it has an optional audible alarm that lets you know when the COVERfree product container is empty.

It comes with a 2-year warranty
