Description

The fitting can be used for all heat flowmeters with the dimensions ¾" × 110 mm and 1" × 130 mm. For heat flowmeters with other dimensions, the adapter set must be obtained by the customer. In the delivery included are the required flat-sealing fitting pieces, thus enabling to install additionally a heat flowmeter.
The fitting for heat flow meter is mounted in the return line of the heating circuit. The sensors can be installed in the ½" sleeves of the thermometer ball valves (extensions might be necessary) or in connections provided by the customer. The immersion sleeve is not included in delivery. When the heat flowmeter is installed, the front insulation may be adapted to the shape of the case (simply by cutting out). As the insulation is closed, we recommend to install the heat flowmeter separately.

The heat flowmeter is not included in delivery!

Safety instructions
The installation and commissioning as well as the connection of electrical components require technical knowledge commensurate with a recognised vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge [specialist].
The following must be observed during installation and commissioning:
- relevant local and national regulations
- accident prevention regulations of the professional association
- instructions and safety instructions mentioned in these instructions.

NOTICE
Material damage due to mineral oils!
Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant properties get lost. We do not assume liability nor provide warranty for damage to property resulting from sealants damaged in this way.
- It is imperative to avoid that the EPDM sealing elements of the unit get in contact with substances containing mineral oils.
- Use a lubricant based on silicone or polyalkylene and free from mineral oils, such as Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.

ATTENTION
The PAW fitting for heat flowmeter must only be used in heating circuits filled with heating water according to VDI 2035 / Ö-Norm H 5195-1. The fitting for heat flowmeter must not be used in domestic hot water applications.
