Installation
The tank must be assembled and installed by a certified specialist company!
When transporting and opening the packaging, the instructions in the note attached to the head of the
buffer must be followed.
If necessary, the prefabricated CFC free fleece insulation with a foil jacket and zip fastener can be
disassembled to reduce the dimensions when positioning (1000R2). The dimensions of the tank may
not exceed the max. insertion dimensions!
The storage tank must be installed in a frost-proof room with short cable routes. When installing the
unit in an attic, a suitable collecting basin with a drain unit must be provided.
The weight of the filled tank may not exceed the max. permitted ceiling loading!
The storage tanks, enameled in accordance with DIN 4753, part 1, are suitable for normal drinking
water. Mixed installation is permitted.
It must be connected in accordance with DIN 1988 and DIN 4753. All connection sockets not used must
be closed with plugs.
The operating overpressure ratings specified on the type plate may not be exceeded. If necessary, a
pressure reducer must be installed.
The enclosed adjusting feet allow the storage
tank to be adapted for height differences at its installation location.

Recommendation
In order to equalize pressure fluctuations or water rushes in the cold
water circuit and to avoid unnecessary water loss, we recommend that
you install a suitable expansion vessel with a flow-through fitting.
