Project Description

Removal of the existing feeder, booster pump, and all associated face piping from the chlorine room to the filtration system will be removed and disposed of offsite. A new 2 HP, 3-phase booster pump will be installed and interlocked with the main circulation pump's mag starter. A dual Venturi manifold will be mounted in the chlorine room, and the main return line will be modified to include a 2" SCH80 PVC side loop to serve the manifold. Electrical work will include installing a new 15A, 208V, 3-phase breaker with a safety disconnect for the booster pump, as well as a dedicated 20A, 120V circuit for the Precision control boxes. Two Pulsar Precision calcium hypochlorite feeders will be installed in the chlorine room, along with the required spray and vacuum tubing. The chlorine feed outputs from the existing chemical controller will be wired to the new Precision control boxes. Finally, the system will be started, tested for proper operation, and undergo a factory
