Specified Use

Hint!
Observe the "Specified Use" chapter
of the installation instructions for the
screw compressor!
The screw compressor package must only be oper-
ated up to a maximum discharge pressure in accord-
ance with the type plate.
It is imperative that you comply with the applicable
conditions of use with respect to pressure and tem-
perature for the screw compressor package.
Do not change the setting values of the safety pres-
sure switch. This would endanger the operating
safety of the refrigeration plant.
If the switch-off value is set higher than 0.9 x maxi-
mum operating pressure (see EN378-2) of the high
pressure section of the refrigerating system, this may
result in the the tank within this section of the system
rupturing.
The operating regime stipulated by the manufacturer,
especially for the starting phase of the screw com-
pressor package, must be observed.
Operating parameters must be monitored. Operating
parameters must not deviate from within the defined
limits.
The screw compressor package has been designed
and manufactured for a specific application under
defined conditions of use. Unauthorised structural
modifications are not permitted. We assume no liabil-
ity for any resulting damage or injury. In the interest
of further development, GEA Refrigeration Germany
GmbH reserves the right to make technical modifica-
tions. The screw compressor package described
here corresponds to the state of the art at the time
this operating manual was published.
The manufacturer must be consulted in all cases as
to the permissibility of the modification if there is any
change of the application or the conditions of use.
Do not make any modifications to the screw com-
pressor package and the compressor control system.
These may impair the safety and functionality of the
SCP. They will also void the guarantee.
The pressure equipment described here must not be
used for any purpose other than the purpose speci-
fied here. The units must only be installed by the
supplier/installer and not by the end user. If the pres-
sure equipment is not used according to the regula-
tions, the safe use of the equipment is not guaran-
teed. The supplier/installer or the operator – and not
14
the manufacturer – is responsible for all personal
injury and damage to property resulting from
improper use.
The pressure equipment is not designed for dynamic
loads. If there is a risk of lightning strikes, the pres-
sure equipment must be earthed. The supplier/instal-
ler must record instructions for regular inspection of
the pressure equipment in his operating manual and
must specify the procedure to be followed by the end
user in the event of damage. In order to prevent
burns or frostbite, the pressure receptacle must not
be touched during operation. This can be prevented
by respective safety measures. Appropriate warning
signs must be affixed. Compressor units or systems
must be equipped with safety valves in accordance
with EN 378. The foundation must provide sufficient
rigidity.
The supplier/installer must carefully install the acces-
sories for the pressure equipment. The pressure
equipment must not be damaged during installation
and must be painted after installation. The pressure
equipment must only be filled with the refrigerant
specified in the contract. The pressure units must be
installed in the compressor unit or the system in such
a way that vibrations or pulses cannot be transferred
to the pressure units. The contacts must be installed
with the power supply disconnected.
Specified use includes observance of this manual
and all supplied operating manuals as well as com-
pliance with the maintenance and service intervals
and conditions stipulated therein.
Warranty claims and authorisation for operation
become void if the equipment is not used for its
specified purpose.
1.5 Warning against foreseeable abu-
sive use
A package/chiller is said to have been abused, if
– unauthorised refrigerants, fuels and lubricants
and secondary refrigerant materials are used.
Hint!
Observe specification for the project!
– electrical components are wrongly connected.
Hint!
Watch voltage and frequency!
– mechanical components are wrongly connected.
