By-pass line assembly includes a monobloc cell housing fitting for Chlorine sensor (ppm) control, pH control, and optional Temperature monitoring. It features Inlet & Outlet service valves connected to 3/8″ tubing, inline strainer, flow indicator, flow control valve, safety flow switch, and water sample valve.

Specifically tailored for compatibility, the PC1555 comes with a 600 x 500 mm PVC sheet backboard, while the PC110c is equipped with a larger 730 x 530 mm PVC sheet backboard.

MODEL 5

Suitable for PC110c

Chlorine (ppm) sensor with pH, ORP, TDS, and temperature capabilities. Designed for pools, spas, water parks, and similar applications.

The controller wiring options include hardwired dosing pumps or General Purpose Outlets (GPOs) ready for connection to dosing equipment. The by-pass line assembly includes two flow control valves, a safety flow switch, a clear acrylic flow cell for the chlorine sensor, a flow indicator, and a water sample valve.

Both the Controller assembly and the By-pass line assembly are mounted on a grey PVC backboard measuring 600×400 mm.

MODEL 6

Monobloc cell housing for water analysis

Suitable for PC1500

pH and ORP control with Temperature monitoring.

By-pass line assembly includes a monobloc cell housing fitting for pH and ORP control, with temperature monitoring. It features Inlet & Outlet service valves connected to 3/8″ tubing, safety flow switch, flow indicator and water sample valve.

Specifically tailored for compatibility, the PC1500 comes with a 600 x 500 mm PVC sheet backboard.

Bypass line & Feature diagram

Pool and Spa programmable controller (PC) range installation:

For optimal installation, it is recommended to mount the controller backboard on the right-hand side, with the plumbing manifold positioned on the left.

Alternatively, another viable option is to mount the plumbing manifold below the controller, maintaining an approximate 300mm gap between these two PVC backboards. This gap is essential for the servicing and maintenance of the chlorine (ppm) sensor.

Bypass line assembly (INLET)

Please connect to the discharge of the main recirculation filter pump, incorporating an inline strainer to ensure water cleanliness before sensor sampling. Ensure that the system maintains a maximum flow of 10 liters per minute (l/m) and a minimum flow of no less than 4 liters per minute (l/m).

*1 – Please ensure the installation includes an additional isolation valve positioned before the inline strainer. This valve is essential for facilitating maintenance and backwash processes, allowing for efficient servicing of the system.

Bypass line assembly (OUTLET)

Please ensure the connection is made before the pool main filter pump on the suction side. This arrangement is designed to promote consistent water flow out of the manifold.

*2 – It is crucial to incorporate an additional isolation valve into the system to facilitate maintenance and backwash processes. This valve will ensure efficient servicing of the system when needed.

Note: As each pool may have variations in filtration and recirculation equipment, we recommend consulting with a CHEMTROL® representative to determine the optimal connection for plumbing inlet/outlet on your facility.

Carbon Dioxide pH control

The schematic illustrates the installation principle, showcasing the recommended optional Automatic Switchover System for continuous pH control assurance.

Gas injection control is attained by connecting the 230v pH control output of the CHEMTROL® controller to the CO2 feeder cabinet.

Multiple CO2 gas cylinders can be manifolded together on each line to meet the required feed rate for maintaining proper pH levels.

Controller with co2 feeder set

For a clean and organized installation, it is recommended to mount the controller and CO2 feeder side by side on a PVC backboard with a thickness of 10mm. Incorporate slotted cable management ducting for a tidy arrangement.

Assembly : grey PVC backboard 730×530 mm.
