Hello Forengemeinde, I got a new LMC Style Lift 500K, and got plenty of stuff in the equipment catalog. Now I could pick him up and had to find out that the Heki2 is missing and instead “only” a small 40×40-Luke is installed. The dealer was first overburdened and could not understand it. After a question with LMC it turned out that one can have either the climate preparation (roof reinforcement) or the Heki2. The 2 positions however are excluded. Neither the The dealer on the knife, the documents and catalogues give this to me. Well. I have a contract and there is both inside for the first time…. The dealer has to bathe it now (although he can not do so), but makes me an offer: Either the subsequent installation of the Heki2 in autumn (if the seasonal stress decreases) for 0€ Or a climate system FreshJet 1500 for 999 or FreshJet 2200 for 1399, each plus 369,-€ installation. Think, the discount is not so wrong, but it falls d of course the central roof hatch away (light/air!). My thought was, after the discussion at the fair, that the climate can be placed in the front skylight – so was the idea then at the fair – if a climate is needed at all. What is absolutely unclear and first has to be tried out. Only the dealer at the fair strongly recommended to me for the preparation, since one can no longer do this afterwards, and the roof is (as a result) walkable. So. I am kla r, that now from 100 people 200 opinions come here, that works for me already. It would be interesting, as you quite personally would decide, in this case. I currently tend rather to the subsequent installation of the Heki 2. Advantages: – More light (in autumn/winter/frühling) – More air – Less weight – Less costs Disadvantages: – Less cold ^^ – If later nevertheless climate, then probably more expensive, because less estate – Manual subsequent installation of the Heki2 with the risk, later Pr Obleme in the tightness/stability to get… (doubts justified?) For assessments of your side I would be happy…
