Product Description

These installation and maintenance instructions apply to the following
types:
Buffer cylinder:
• PW 750.6 PN6 for increased operating pressure
• PW 500, 750, 1000.6 (W) (special version for heat pumps)
• P 500, 750, 1000.6 (W)
• P 500, 750, 990, 1000, 1300.6 M(W)
Buffer cylinder with connections for temperature-dependent return
feed and connection for a immersion heater:
• PR 500, 750, 1000, 1300.6 E(W)
Solar buffer cylinder with connections for temperature-dependent
return feed and connections for the solar system and immersion heater:
• PNR 500, 750, 1000, 1300.6 E(W)
Heat pump buffer cylinder with connections for temperature-dependent
return feed and connections for the immersion heater:
• PRZ 500, 750, 1000.6 E(W)
The PRZ 500, 750, 1000.6 E(W) is also equipped with a separating
plate. The separating plate makes it possible to divide the interior of the
cylinder into standby and heating areas. In addition, the flow feed lance
ensures that the heat pump inflow remains stable. Special flow and
return pipes in the heating areas ensure a low temperature loss.
Heat pump buffer cylinder with connections for temperature-dependent
return feed and connections for the solar system and immersion heater:
• PNRZ 750, 1000.6 E(W)
The PNRZ 750, 1000.6 E(W) also has two separating plates. The
separating plates make it possible to divide the interior of the cylinder
into standby, heating and solar areas. In addition, the flow feed lance
ensures that the heat pump inflow remains stable. Special flow and
return pipes in the heating areas ensure a low temperature loss.

Determined use

These buffer cylinders may only be filled with heating water and used in
sealed heating systems.
The buffer cylinders can be used for indirect potable water heating via a
freshwater station.
Only fill solar heat exchangers with propylene glycol/water mixtures
(heat transfer medium L or LS). The use of any other heat transfer
medium is not permitted.
