3.3 Special hazards

Before a fitting is removed from the system or before a fitting is dismantled but partially
remains in place, the pressure in the system on both the inlet and outlet side must be
completely reduced so that there is no uncontrolled flow of the medium out of the system.
In the case of toxic or hazardous media, the system must be completely drained
danger of
before the fitting is removed.
fatalities
Caution is required with residues that might continue flowing.
If a fitting is removed from a system with a toxic medium and is taken out of the plant:
it must be properly decontaminated before repair.

4 Transport and storage

A fitting must be handled, transported and stored with care:
The fitting must be transported and stored in its protective packaging until it is installed.
•
The fitting has moving internal parts and external floats and lever systems.
Even packaged fittings should be transported smoothly without any shocks.
caution
In the case of a fitting that can no longer be transported by hand, the lifting gear must be
attached to a suitable position on the housing (branches).
Under no circumstances may the lifting gear be affixed to any attachments or
caution
external floats or float lever.
When the fitting is stored prior to installation, it should be kept in closed rooms and protected against
•
harmful influences such as dirt, moisture and frost.
In special cases, the fitting is supplied free of oil, grease or silicone and is marked accordingly.
•
A fitting such as this must not come into contact with oil/grease/silicone during storage and handling
(particularly when subsequently unpacked).
A MANKENBERG fitting generally has functional and/or sealing parts made of elastomer materials.
•
These cannot be stored for an unlimited period.
ISO 2230 describes the storage conditions for elastomers in detail and specifies the
permissible storage period.
Functional and sealing parts must be replaced well before the storage period
note
expires. They are available from MANKENBERG as a "service set".
See also Section 10 <Troubleshooting help>.
MANKENBERG fittings of small and medium nominal diameters are largely made of
stainless steel (high-alloy CrNiMo steel).
If, under exceptional circumstances, fittings are stored in a unpacked state, they must be
note
protected against ferritic dust to avoid corrosion.
The fitting is generally not capable of standing alone:
Handle with care so that the fitting does not tip over during transport/storage.
