4.4 Acoustic Data
Acoustic data have been determined in a reverberation
chamber in the LTG test lab.
The technical data sheet contains the A weighted sound
pressure levels L
A18
for different primary air flow rates/
static pressures at primary air socket.
Sound pressure levels apply to a room absorption surface
of 194 ft
2
Sabine which equals a room absorption of about
6 dB(A). Thus, sound power levels may easily be calcu ­
lated.
L
WA
= L
A18
+ 6,5 dB(A)
The data given apply to one unit, i.e. one room axle. If more
than one unit is installed in the same room, the sound
pressure level will rise accordingly.
Increase in sound level with several sound sources of the
same type:
Number of sound sources of
the same type
1 2 3 4
Sound level increase [dB] 0 3 5 6
Measuring accuracy is ± 10%.
4.5 Hydraulic Data
Heat exchangers are approved for an operating pressure
of 145 psi max. (test pressure 232 psi). Pressures exceed
­
ing 145 psi require the express permission of LTG.
Water-side pressure losses have been measured directly
at the heat exchanger connections. Further resistances
will have to be added.
Measuring accuracy is

10%.

5.1 Notes
Shipping of Unit
If not required otherwise, units are shipped in wrapping
boxes which may also serve as a protection during instal
­
lation. Boxes must be stored in an upright position as indi ­
cated by the arrow on the box. The packaging is disposable
and not to be returned to LTG.
Timing of Installation
Installation of the units should not be performed unless
the prefabricated floor has been finished, the window sill
installed, the intermediate ceiling and any other dust pro
­
ducing work completed.
Handling of Units
Handle units with care during transport and installation.
Avoid dropping to the ground.
5.2 Suspension
For reasons of stability and rigidity, never
use bolts with a property class inferior to
the one indicated. Fixing elements are not
included in the delivery.
Do not use other than the holes provided for to fasten fix ­
ing elements.
Do not use the air conditioning units as load-bearing ele ­
ments for other components and avoid any other load ­
ing.
Fixing elements must be chosen in a way to ensure that
any sound transmission is avoided.
Parts and tools.
When working overhead.
