4 Transport
A crane is appropriate for transport. Alternatively the cylinder can be
transported using a pallet truck or forklift truck (

Fig. 4, page 68).
5 assembly
▶ Check that the buffer cylinder is complete and undamaged.
5.1 Installation location
If there is a danger that water may collect on the floor of the installation
site:
▶ Position the buffer cylinder on a plinth.
▶ Site the buffer cylinder in dry, ventilated internal areas that are free
from the risk of frost.
▶ Observe the minimum room height (

table 6, page 66, table 7,
page 67 and table 8, page 68) and minimum wall clearances
(

fig. 5, page 69) in the installation location.
5.2 Installing the temperature sensor
500 litre cylinder (

Fig. 6ff, page 69)
Assembly is also possible once the insulation has been installed.
▶ Observe the technical guide when positioning the sensor.
▶ Apply heat conducting paste to the contact surfaces.
▶ Insert the temperature sensor with installation set (part of the sensor
set) in the sensor pocket until it comes to a stop.
▶ Mark the temperature sensor leads at the end of each lead according
to sensor use.
▶ Route the sensor lead to the controller, ensuring it will be possible to
install the insulation.
▶ Electrical connection to the sensor leads. Observe the controller
installation instructions during this process.
750...1300 litre cylinder (

Fig. 7, page 70)
▶ 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 sensor surface makes contact with the storage cylinder.
▶ Mark the temperature sensor leads at the end of each lead according
to sensor use.
▶ Route the sensor lead to the controller, ensuring it will be possible to
install the insulation.
▶ Electrical connection to the sensor leads. Observe the controller
installation instructions during this process.
1) VOB: German contract construction procedures – Part C: General technical
specifications in construction contracts (ATV)
DANGER: Risk to life through falling load.
▶ Only use lifting cables that are in a faultless condition.
▶ Only insert hooks into the lifting eyes provided.
Tilting danger with forklift trucks or pallet trucks.
WARNING: Risk of injury through carrying heavy loads
and inadequately securing loads for transport!
▶
At least two persons are required for transportation
and installation.
▶ Use suitable means of transport.
▶ Secure the buffer cylinder to prevent it falling.
Applies to 750...1300 litre cylinders:
▶ Remove the foil jacket and rigid foam shells before
transporting and store in a clean place.
NOTICE: Risk of material damage from frost and corrosion.
▶ Site the buffer cylinder in a dry, frost-free room.
