3.11 Pressure maintenance

B Size the expansion vessels correctly.
B Set the pre-charge pressures correctly.
If using pump-controlled pressurisation units, pressure fluctuations will
occur. They can occur very frequently depending on the design of the
system and the appliance settings. Even if these pressure fluctuations
are small, if they occur very frequently they may cause considerable
damage to the boiler, as it is designed for a predominantly static
pressure load.
To protection against damage:
B Ensure that every heat source is equipped with a separate expansion
vessel.
B Set the pre-charge pressure of the expansion vessel correctly.
Recommended minimum volume of the expansion vessels if using pump-
controlled pressurisation units:

Transport

DANGER: Risk to life from inadequately secured boiler.
B Use suitable means to transport the boiler (e.g.
several pallet trucks, a forklift truck, crane or heavy
duty rollers).
B When transporting, secure the boiler to prevent it
falling.
The transport height can be reduced by removing the
base frame rails
(
Fig. 1, [7], page 6).
Securing the load
To secure the load during transportation:
B Never pull retaining straps (fixing straps, chains) [2] over the boiler
insulation [1].
B Only secure retaining straps to the locking lugs [3].
The maximum tensile strength of each chain is 2 kN.

Moving the boiler with a forklift truck, pallet truck or
heavy duty rollers
DANGER: Risk to life through falling load.
B Distribute the boiler weight evenly across the forklift
truck/pallet truck when lifting and moving the boiler.
B Observe the weight of the boiler and that of the means
of transport.
B When transporting, secure the boiler to prevent it
falling.
NOTICE: System damage through damaged boiler body.
Only move the boiler with a forklift truck if the forks are
long enough to reach right under the boiler.
B Prior to lifting the boiler, check that both lateral
profiles of the boiler are supported by the forks of the
forklift truck.
B Only lift the boiler at its profiles and base frame, not at
the boiler body.
B Transport the boiler with the forks of the forklift truck
inserted from the side.
The boiler can be transported by crane, forklift truck, several pallet
trucks or rollers.

4.1.1 Lifting the boiler with a crane

DANGER: Risk to life through falling load.
B Only use lifting ropes of the same length.
B Only use lifting ropes that are in perfect condition.
B Only hook lifting tackle into the lifting eyes provided in
the gusset plates on top of the boiler.
B Never hook lifting tackle into the locking lugs on
the front and back of the boiler, or into the
connectors.
B Only lift the boiler with a crane if you are suitably
qualified to operate the crane.
B Never lift the boiler with a crane on its side or on end.
