Strange: in the zugschweißten pack there is a German and an English manual. The English is less than the German adapter. With me 4 times the English adapter bag was there.
Had it been the German manual to, a heart-adapter had been there.
(See picture gallery)
Just as the package arrives, it fits to the following valves:
(From Adapter table of instructions)
- Honeywell Braukmann, MNG, Heimeier, Junkers Lands & Gyr 'Duodyr'
- Adapter for Danfoss RA | RAV | RAVL,
- Adapter for Caleffi (only if you get a bag of adapters to German instructions)
- (Not another word for heart-Adapter)
Does not fit with Oventrop "M 30 x 1.0 OV" thread. Here is definitely need an adapter to "M30x1,5"
For more information whether an adapter is required or not: "klimalex thermostatic valve adapter" googling.
