Firstly this geyser uses proprietary fasteners which the company does not ship in box. And these fasteners are not available in market. Bought this geyser from delhi electric kotla 45 days back and yet not installed. Have tried racold customercare/ area service manager Vinit(tel:9015897712) and not one cares to take the effort to provide service. They all say will check and revert and till now not installed. This is the service they give to clients buying their most expensive model.
