and Storage

5.1 Packaging

Safety valves are checked for damage and
leaks before delivery. For safe transport, all
sealing surfaces, sealing lips and threads
must be protected against damage using
protectors.

5.2 Transport

Safety valves may only be lifted by the
transport tabs/cast support brackets (only
A) and ring nuts provided for transport
(only B). Safety valves which do not have
any transport tabs/cast support brackets
must be transported with suitable transport
aids, such as lifting belts.
Safety valves must not be lifted by the
venting lever or by any outside pipework.
Safety valves must be transported careful-
ly. Safety valves must not fall over. Vibra-
tions and impacts may damage the sealing
surfaces.
Safety valves must be protected against
soiling during transport. Protectors and
suitable packaging must be used.

5.3 Storage

Safety valves must be stored in a dry area
and protected against soiling.
The safe storage temperature is between
5 °C and 40 °C.
The upper limit for the storage temperature
is 50 °C, and the lower limit is -10 °C.
Safety valves are equipped with flange pro-
tection caps at the factory. These flange
protection caps must be in place during
storage.
If safety valves are stored at temperatures
below zero degrees, then the temperature
resistance of the materials (e.g. of seals)
must be taken into consideration.

Installation

6.1 General Information about Instal-
lation
Only trained personnel may install safety
valves.
Training can be obtained in seminars from
LESER, from experienced personnel in
workshops, or by studying the documen-
tation provided by LESER such as video
films, catalogues and installation guides.
Besides these general installation instruc-
tions, there are also type-specific installa-
tion guides. Those installation guides must
be observed.
Safety valves must be secured in accord-
ance with the specifications in the draw-
ings. All designated fastening elements
