Hint!
GEA Tuchenhagen recommends Rivolta F.L.G. MD-2 and PARALIQ
GTE 703. These lubricants are approved for foodstuff and are resistant
to beer froth. They have the NSF-H1 (USDA H1) registration. They do
not affect the taste or the consistency of the products and are
compatible with the seals in contact with product.
PARALIQ GTE 703 can be ordered from GEA Tuchenhagen under
material no. 413-064, and Rivolta F.L.G. MD-2 can be ordered under
material no. 413-071. Using other types of grease can result in
malfunctions or in premature seal failure. The warranty will also
become null and void.
A Manufacturer's Declaration for these products can be obtained from
GEA Tuchenhagen if required.
A thin film of grease is required on the seals to ensure the proper
function of the fittings. It reduces friction and extends the service life
of the seals. This is absolutely harmless from a health and hygienic
point of view.
Running dry must be avoided!

Installation
Assemble the valve in reverse order of disassembly. Observe the notes and
instructions given in the following sections when doing so.
10.7.1 Reconnect the cleaning hose
Prerequisite:
•
The cleaning hose is made of plastics. When screwing the cleaning hose on,
it can become easily constricted in the area of the sealing disc and the
cleaning hose can become detached. Therefore, during assembly of the
cleaning hose, insert sleeves must be used.
