General information

• The meter left the factory in a faultless condition where safety and hygiene are concerned.
• Calibration-relevant security seals on the meter must not be damaged or removed. Otherwise, the guarantee and calibration validity of the meter will lapse.
• Further technical support will be provided by the manufacturer on request.

Safety information

• The meter may only be used in building service engineering systems and only for the applications described.
• The local regulations (installation etc.) must be adhered to.
• Adhere to the operating conditions according to the dial plate during use. Non-adherence can cause hazards and the guarantee will lapse.
• In no case do any welding, drilling, or soldering near the meter.
• Do not lift the meter by the electronic unit.
• Protect the meter against damage from shocks or vibrations at the mounting place.
• Only personnel trained in the installation and operation of meters in building service engineering sys-tems, may install or remove the meter.
• The meter is suitable for drinking water. Take necessary hygiene measures during installation:
  • Only remove the meter from its packaging at the mounting place.
  • Wear disposable gloves.
  • Clean and sanitize the relevant tools before installing the meter.
  • Protect the measuring tube and thread surfaces from dirt and contact.
• Be aware of sharp edges on the thread, flange, and measuring tube.
• After installing the meter, check the leak-tightness of the system.
• As far as disposal is concerned, the meter is a waste electronic appliance in the sense of European Di-rective 2012/19/EU (WEEE) and it must not be disposed of as domestic waste. The relevant national, legal regulations must be observed as the appliance must be disposed of via the channels provided for this purpose. The local and currently valid legislation must be observed.
• You can return the lithium batteries to the manufacturer for appropriate disposal following use. When shipping please observe legal regulations, in particular, those governing the labeling and packaging of hazardous goods.
• Do not open the batteries. Do not bring batteries into contact with water or expose them to temperatures above 80 °C.
• The meter does not have any lightning protection. Ensure lightning protection via in-house installation.

Installation

• Note: During installation, adhere to the notes from chapters 1 and 2.
• Note: Observe the dimensions of the meter and check whether there is sufficient space available.
• Note: The meter must not be exposed to stress or forces caused by pipes or fittings. If this cannot be guaranteed permanently, improve the installation site or fix the pipes, e.g. with suitable connection brackets.

To install the meter, proceed as follows:

1. Close all valves before and after the mounting place.
2. If necessary, remove the old meter. Collect the excess water in a suitable container.
3. Remove the old sealings and residues of teflon tape and hemp.
4. Clean the union nuts thread and the sealing surfaces at the screw connections.
5. Install the provided sealing at the threaded connector of the meter. Check if the sealing is properly positioned and is free of damage.
6. When using a backflow preventer, check its correct placement at the meter (see Chapter 7).
7. Fit the meter horizontally or vertically so that the arrow on the housing and the flow direction match.
8. Tighten the screw connections. Note and use the tightening torques specified in the following table and the corresponding angle from the contact of the union nut with the gasket:
   Flat gasket| Novapress basic
   ---|---
   Meter thread| ¾‘‘| 1‘‘
   Tightening torque| 10 – 15 Nm| 25 – 30 Nm
   Angle from contact| 45 – 60°| 45 – 60°
9. Pay attention to the correct placement of the union nut.
10. Ensure that all connectors are tightened securely and that tthe meteris properly installed.
11. Open all valves before and after mounting place andpreventt theinstallation.
12. Check the installation for leakage.
13. Seal the screw connection to protect it against manipulation(see chapter 8).
