Transport

DANGER: Risk to life through falling load.
▶ Only use lifting ropes that are in perfect condition.
▶ Only insert hooks into the lifting eyes provided.
WARNING: Risk of injury through carrying heavy loads
and inadequately securing loads for transport.
▶ Use suitable means of transportation, e.g. a sack
truck with strap.
▶ Secure the buffer cylinder to prevent it falling.
A sack truck or crane is required for transportation. Alternatively, the
cylinder can be transported using a pallet truck or forklift truck.
▶ Transport with a sack truck ( Fig. 3, page 49)
▶ Transport with a crane ( Fig. 4, page 49)

Fitting

5.1

Installation location

NOTICE: Risk of material damage from frost and
corrosion.
▶ Site the buffer cylinder in a dry, frost-free room.
5.2

Installing the buffer cylinder

 Fig. 5, page 49 and Fig. 6, page 50
5.3

Hydraulic connection

For buffer cylinders with 80 mm thermal insulation, the thermal
insulation must be installed before the pipework.
For buffer cylinders with 120 mm thermal insulation, we recommend
installing the pipework before fitting the thermal insulation.
Observe the technical guide when establishing the hydraulic
connection.
DANGER: Risk of fire from soldering and welding.
▶ As far as possible, carry out any soldering and
welding work before installing the thermal insulation.
▶ Take appropriate protective measures when
soldering and welding as the thermal insulation is
combustible (for example, cover the thermal
insulation).
▶ Check the integrity of the thermal insulation after
completing work.
NOTICE: Water damage from leaking connections.
▶ Fit all connection lines free from stress.
To prevent damage to the buffer cylinder:
▶ Use installation material that is heat-resistant up to 90 °C.
▶ For solar connections, use installation material that is heat-resistant
up to 130 °C.
▶ Only use the buffer cylinder in sealed systems.
▶ Never use open expansion vessels.
We recommend using screw fittings with shut-off valves
to connect lines to the cylinder.
▶ Install a drain valve on site at the lowest point of the lower
connection.
5.4

Installing temperature sensors

 Fig. 8 , page 50
▶ Observe the technical guide when positioning the sensor.
▶ Apply heat conducting paste to the contact surfaces.
▶ Insert the temperature sensor into the spring clip so that the entire
length of the contact surface makes contact with the storage
cylinder.
▶ Mark the temperature sensor leads according to how the sensor is
being used; do this at the end of each lead.
▶ Route the sensor lead to the controller, ensuring it will be possible to
install the insulation.
▶ Establish the electrical connections for the sensor leads; observe the
controller installation instructions during this process.
