Notes on reducing noise and vibration
4.8.1.
Noise
Details of your chiller's airborne sound emissions are given in
Chapter 4.7
.
To reduce noise pollution caused by airborne sound emissions it is advisable to install the chiller out of doors
and out of the range of workplaces.
If this is not possible we recommend that when the unit is installed attention is paid to ensuring that the air
intake side is not pointed directly at a workplace/workstation.
High ambient temperatures mean high fan speeds and this increases the noise levels produced. It is
advisable not to expose the chiller to direct sunlight or to install it in rooms with high air temperature. Further
information is given in
Chapter 6.2 Installation site
.
4.8.2.
Vibration
The chiller is designed so that the vibrations caused by the compressor are largely isolated by the chiller's
frame.
To minimise the effect of vibration still further it is possible to install the chiller with optionally available
levelling feet (see
Chapter 3.7 Levelling feet (accessories)
). These are fitted with damping elastomers.
4.9.
Residual risks
4.9.1.
Electrical
If all safety provisions are complied with there is no risk.
4.9.2.
Mechanical
If all safety provisions are complied with there is no risk.
Mechanical damage to components or pipes of the refrigerant circuit can cause refrigerant to leak. Leaking
refrigerant can cause cold burns.
4.9.3.
Chemical
ATTENTION: The mains voltage must comply with the quality characteristics of EN
50160 and the defined standard voltages of IEC 60038.
The electrical connection on the building side is the responsibility of the operator.
The operator must ensure that the limit values permitted in DIN EN 60204-1
(occurrence of a leakage current to earth at any mains connection of more than 10 mA
AC or DC) are complied with, and that measures are taken to reduce them to non-critical
values if they are exceeded.
ATTENTION! Toxic and caustic products are produced by the thermal decomposition of
the R410A refrigerant.
ATTENTION! Do not install in rooms with naked flames or smoke.
