5.3 Positioning the buffer cylinder, fitting the thermal
insulation
NOTICE: Material damage from a low ambient temperature.
If the ambient temperature is below 15 °C, the
foil jacket tears while closing the zipper.
▶ Warm the foil jacket (in a warmed-up room) to above
15 °C.
The following applies for the ErP "B" cylinder with one
connection level:
▶ The hydraulic connection can be established before
the thermal insulation is installed.
The following applies for the ErP "B" cylinder with two
connection levels:
▶ If necessary remove perforated material on connector
pipes.
▶ Covers are available (as accessory) for the slots
500 litre cylinder ( Fig. 9, page 63)
▶ Remove packaging.
▶ Remove casing lid and top insulation.
▶ Remove thermal insulation (ErP "B") or foil jacket (ErP "C") and store
provisionally.
▶ Unscrew the cylinder from the pallet.
▶ Optional: fit the adjustable feet (accessory).
▶ Position and align the cylinder.
▶ Fitting the thermal insulation
– ErP "B": establish hydraulic connection, fit separate
thermal insulation. Close with Velcro fastener.
– ErP "C": fit foil jacket. Close the zipper.
▶ Place the top insulation and casing lid on.
▶ Remove the plug from the connector.
750-1300 litre cylinder ( Fig. 9, page 63)
▶ Remove packaging.
▶ Provisionally store bag with accessories and floor insulation panel.
▶ Remove casing lid and top insulation.
▶ Provisionally store thermal insulation:
– ErP "B": separately packaged polystyrene jacket.
– ErP "C": remove foil jacket.
▶ Remove fixing straps.
▶ Pull off the PU rigid foam halves.
▶ Unscrew cylinder from the pallet.
▶ Lift the cylinder off the pallet.
▶ Optional: fit the adjustable feet (accessory).
▶ Position and align the cylinder.
▶ Attach floor insulation panel, paying attention to the slots for the feet.
▶ Fitting the thermal insulation
– Fit PU rigid foam half-shells, draw together with a ratchet strap,
tap. Fit fixing straps. Remove ratchet strap.
– ErP "B": fit fleece strip round the connector pipes and attach
fleece circular blank for the cover and push in firmly. Make a hole
for the connector in the polystyrene jacket by cutting round the
perforation with a cutter knife. Fit top layer, unrolling it to the
right. Pay attention to the position of the connector.
Close Velcro fastener
– ErP "C": fit foil jacket, pull zipper shut
▶ Place the top insulation and casing lid on.
▶ Mount logo.
▶ Remove the plug from the connector.

Hydraulic connection

Before installing pipework:
▶ Install the thermal insulation/foil jacket.
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 fitting 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 on the heating circuit side 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.

Immersion heater (accessory)

If an immersion heater is used:
▶ ( Fig. 22, page 66)
– ErP "C": cut round perforation to create recess.
– ErP "B": insert compass provided, turn to cut out circular piece.
▶ Install the immersion heater in accordance with the separate
installation instructions.
▶ When the cylinder installation is complete, inspect the earth
connection (including the metal connection fittings).
