Safety instructions

General
These installation and maintenance instructions are intended for
contractors.
Failure to observe the safety instructions can result in serious injuries.
▶ Read and follow the safety instructions.
▶ Install and commission cylinders and their accessories according to
the relevant installation instructions.
Transport and installation
▶ At least two persons are required for transportation and installation!
Siting and conversion
▶ Fire hazard! Soldering and welding can lead to a risk of fire as the
thermal insulation is combustible. The buffer cylinder must only be
installed or converted by an authorised contractor.
▶ Never use open expansion vessels.
▶ Never close the pressure relief valve!
Function
▶ Observe these installation and maintenance instructions to ensure
trouble-free operation.
▶ Risk of scalding! When the buffer cylinder is in operation,
temperatures over 60 °C can occur.
Service work
▶ Recommendation to customers: Arrange a maintenance and
inspection contract with an approved contractor.
▶ Only use genuine spare parts.
Instructing the customer
▶ Instruct the user in how to operate the buffer cylinder and draw their
attention to safety-related points.
▶ Hand over the installation and maintenance instructions to the user

Product Description

These installation and maintenance instructions apply to the following
types:
Buffer cylinder:
• BH 750-6 PN6 for increased operating pressure
• BH 500, 750, 1000-6 (special version for heat pumps)
• B 500, 750, 1000-6
• B 500, 750, 990, 1000, 1300-6 M
Buffer cylinder with connections for temperature-dependent return
feed and connection for a immersion heater:
• B 500, 750, 1000, 1300-6 ER
Solar buffer cylinder with connections for temperature-dependent
return feed and connections for the solar system and immersion heater:
• BS 500, 750, 1000, 1300-6 ER
Heat pump buffer cylinder with connections for temperature-dependent
return feed and connections for the immersion heater:
• BH 500, 750, 1000-6 ERZ
The BH 500, 750, 1000-6 ERZ 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:
• BHS 750, 1000-6 ERZ
The BHS 750, 1000-6 ERZ 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.
