Installation, operating and maintenance instructions
Active chilled beams HDF-600, ceiling installation

Check after installation
Mechanical check
Having completed the installation the unit is to be checked
for any mechanical damages. Remainders of the packag
ing material and dust in or on the unit must be removed.
Check the following:
- leakproofness of the water connections (including heat
exchanger connections),
- the insulation of all cold water carrying components to
the heat exchanger for damage,
- the fixing screws for proper fit,
- the suspension for rigidity and sufficient load-bearing
capacity (ceiling units),
- the unit's connection,
- the diffusion area/diffusion grille of the unit to be free of
any obstructions,
- proper horizontal alignment, accurate to dimension,
- sufficient water hose lengths and strainless laying,
- The unit must be supported from the ceiling slab. The unit
must not be supported by the the ceiling grid.
Check for media supply
- Check for proper availability of primary air, cold water,
warm water, and electrical power or compressed air for
the control.
- Check whether voltage and line frequency comply with
the data given on the actuator's type plate. Never oper
ate control devices with inappropriate voltage or fre
quency since this might result in destruction of the units
and put people at risk.
Warning: Make sure
- all windows are closed
- and the building is free from air filtration
- and the space dewpoint has reached the
design setpoint
prior to opening chilled water valves.
Do not apply excessive force in tightening
water connection fittings. The use of ex
cessive force could result in fracturing of
the water pipes ot their bolder points.
Control technical equipment
Supply of control devices by LTG Aktiengesellschaft is op
tional, however it is the rule for actuators for units with
dampers. Control valves are often factory-mounted.
Check for proper functioning
Turn the temperature control's selection knob slowly
from one end position to the other while keeping an eye on
the control dampers and linkage or the valves. Dampers
and valves must move correspondingly quite smoothly
and without rattling noises from one end position to the
other.
No exceptional noise must be produced by the electric ac
tuators. In case the units show damages have them prop
erly repaired by an expert. Damper linkages have been
gauge adjusted in the factory and, therefore, require LTG
Aktiengesellschaft's skilled personnel for readjustment.
Starting Standard Operation
Then set the temperature controller to the desired tem
perature. After a certain time the indoor air temperature
should meet the setpoint.
