Description

Mit Hilfe des Pumpensets wird eine Unterschreitung des Taupunktes im Kessel und damit die Kesselversottung verhindert. Das Pumpenset wird zwischen dem Pufferspeicher und dem Kessel montiert. Der Stellmotor PM2 wird von einem externen Regler angesteuert. Der Stellmotor öffnet das 3-Wege-Ventil erst, wenn der Kesselkreis die eingestellte Öffnungstemperatur erreicht hat. Dann steht die Leistung der Pumpe zur Beladung des Speichers zur Verfügung.
Pumpensets DN 40 und DN 50 mit Pumpen in DN 32 werden inklusive Reduzierflansche geliefert. Pumpensets in DN 25 und DN 32 werden inkl. Isolierung geliefert.

Product information

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.

CAUTION
Personal injury and damage to property!
The product must only be used in heating circuits filled with heating water according to VDI 2035 / Ö-Norm H 5195-1. The product must not be used in domestic water applications.

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.
