KEMIDOSE pH+ORP Pump Seko Instruction Manual

KEMIDOSE pH+ORP Pump Seko

Product Information

The KemiDose Double is a system that allows for precise measurement and injection of chemicals into a water system. It is designed to ensure accurate pH and ORP levels in water treatment processes. The package includes various components such as hoses, valves, probes, filters, and mounting brackets.

The KemiDose Double system is available in two configurations:

KemiDose pH – ORP: This configuration includes 2 pumps, 2 suction hoses, 2 delivery hoses, 2 ball valves, 4 probe-holders, 1 tapping saddle, 1 reducer, 1 foot filter, 1 mounting bracket kit, 5 filter minors, 1 probe holder with chlorine probe, 1 pH probe, 1 redox probe, 1 cleaning brush for chlorine probe, and 1 set of balls for chlorine probe.

KemiDose pH – ORP – CL: This configuration includes additional components for chlorine measurement and injection. It includes all the components of the KemiDose pH – ORP configuration, plus an additional probe holder with chlorine probe, pH 4 and pH 7 buffer solutions, a calibration solution, a filter wrench, and a PVC hose for probes holder.

Note: The WiFi model of the KemiDose Double may include an extra piece of certain components.

Product Usage Instructions

Warning

Before carrying out any work inside the control panel of the KemiDose device, ensure that it is disconnected from the power supply. Failure to comply with this instruction could result in injury or damage to the appliance and system.

Installation Instructions

Probe Positioning: For optimal probe reading, position it perpendicular to the tubing.

Use with Salt Chlorinator: When using the KemiDose system with a salt chlorinator, follow these instructions to prevent malfunctioning or damage:

1. Position the pH measuring probe prior to the chlorinator cell.
2. To eliminate eddy currents, connect the pool water to an electrical ground point.
3. Position the product injection point after the chlorinator cell.

Electrical Connections

• Refer to the connection label for the corresponding input and output connections. Ensure proper connections are made to the power supply, pumps, probes, and other components as indicated in the label.

WARNING

• Before carrying out ANY work inside control panel of the KemiDose device, make sure you disconnect it from the power supply.
• Failure to comply with the instructions contained in this manual could cause injury to people and/or damage to the appliance and the system.

WARNING: These products are DANGEROUS (IA) and require special precautions during use, handling and storage.

• NEVER mix chemical products.
• NEVER allow children or people who have not read this manual to use or tamper with KemiDose or any of its peripheral components (including chemical products).

pH chemical products:

• ABSOLUTELY not recommended => pure sulphuric acid
• Recommended for lowering pH => negative pH (with a sulphuric acid base)
• Recommended for raising pH => positive pH (sodium carbonate or bicarbonate)

ORP chemical products:

• ABSOLUTELY not recommended => all types of organic chlorine
• Liquid chlorine or 12% bleach can be used neat. If the product has a concentration of 48%, it is necessary to dilute it in water in a 1:3 ratio.

The pH / ORP probes are subject to wear and tear and therefore are not covered by the warranty.

INSTALLATION INSTRUCTIONS

Warning

• Make sure that the injection pressure is below 1.5 bar

Probe positioning

Installation plant

Warning: Use with salt chlorinator:

For the pH systems, to prevent the risk of system malfunctioning or damage, observe the following instructions:

1. Position the pH measuring probe prior to the chlorinator cell.
2. To eliminate eddy currents, connect the pool water to an electrical ground point
3. Position the product injection point after the chlorinator cell.
