Installation, operating and maintenance instructions
Active chilled beams HDF-600, ceiling installation
7.2
Heat exchanger, water connections
It is recommended to vacuum clean the heat exchanger on
a regular basis.
The heat exchanger blades
are sharp-edged.
Wear gloves for protection.
Check water connections and heat exchanger for tight
ness and possible corrosion damages.
If corrosion occurs inside the heat exchangers skilled
staff must check the water treatment.
7.3
2-pipe and 4-pipe system
Here a few explanations regarding
two-pipe systems
and
four-pipe systems
for easier understanding:
The
two-pipe system
has 2 water connections (supply and
return) with one heat exchanger for either heating or cool
ing, or for heating in winter and cooling in summer.
The
four-pipe system
has 4 water connections (2 each for
supply and return, one each for warm water and cold wa
ter) with 2 heat exchangers or one heat exchanger with
separate water circuits, for heating and cooling.
7.4
Selecting the room temperature
Set the room temperature controller to the desired value
(usually in the range's center). If, after a certain time, you
consider this too cold turn the knob in direction of
”warmer”. If considered too warm, turn the knob in direc
tion of ”cooler”.
In order to find the right setting meeting your personal
needs adjust in small steps and allow sufficient time for
walls, ceilings, floors, furniture to adapt (about
½ to 1 hour).
7.5
Out-of-service times
If the primary air system is not to be operated for a longer
period of time in summer, shut off the cold water supply
to the induction units' heat exchangers to avoid conden
sate formation, overflow, and thus damages.
7.6
Repair
If the damage is not obviously a mere ”damage to the
bodywork”, e.g. on the condensate tray or outlet, units
should be completely replaced and checked by the
factory
.
The filter in front of the heat exchanger (option) is easy to
replace since it is fixed to the unit with a simple adhesive
strip.
Replacement of the control unit should be
performed by skilled staff only or by the
factory.
Replacement of individual components, is
not recommended since the greater num
ber of settings can only be performed in
the factory using special equipment.
