Screw connection (flexible hoses or screw connection)
- Ensure that the surfaces are clean
- Insert seal and tighten screw connection by hand.
There is a risk of damage to the heat exchanger if it is not installed correctly!
Always use a suitable tool to counter the tightening force in order to prevent any damage.
Soldered joint
Clean the pipe ends and make a proficient solder joint.
Filling the heat exchanger
NOTICE!
Subzero temperatures will damage the heat exchanger!
Only fill the heat exchanger if there is no danger of freezing.
Fill the heat exchanger and vent it. To fill the system, use clean tap water (pH value 6.5 to 9) or a water glycol mixture (max. 30% glycol).
Check the system for leaks immediately after installation and then at regular intervals.
Connecting the ductwork
Active chilled beams are fitted with a primary air (fresh air) spigot.
Commissioning
Spigots are suitable for circular ducts according to EN 1506 or EN 13180.
Before you start commissioning:
- Check active chilled beams for correct position
- Remove protective films, if any
- Ensure that all connections are correct
- Ensure that all active chilled beams are clean and free from residues and foreign matter
- Ensure that the water system including the heat exchanger has been filled and vented.
Adjusting the air control blades
The air discharge pattern can be changed by adjusting the optional air control blades in 15° increments up to 45° to the left or right.
Fig. 8: Changing the air discharge pattern
Three air distribution patterns can be set.
NOTICE!
Incorrect handling will damage the air control blades!
To avoid any damage, always use both hands to adjust the air control blades.
Fig. 9: Examples
① Straight air discharge
② Angled air discharge
③ Divergent air discharge
Adjusting the nozzles
The DID614 is fitted with adjustable twin nozzles that allow for adapting the airflow velocity to changed operating conditions at a later stage, if required.
CAUTION
Hot surfaces!
Danger of burn injuries when working on the hot water system.
Before working on the water-side connections, shut down the system and let it cool down.
Fig. 10: Opening the induced air grille
-
To open the induced air grille (Fig. 10/1), pull it down. To completely remove the grille, unhook the safety cables (Fig. 10/2) by pulling them down with the retaining plates (Fig. 10/3).
Fig. 11: Adjusting the nozzles on the DID614
-
Loosen the Allen screws (SW4) (Fig. 11/4) of the flat adjustment bar (Fig. 11/1).
-
Slide the flat adjustment bar back or forth to open or close the nozzles as required:
- small nozzle open (Fig. 11/2) (DS)
- large nozzle open (Fig. 11/3) (DB)
- both nozzles open (DA, factory setting)
-
Manually tighten the Allen screws of the flat adjustment bar.
-
Fix the induced air grille.
Cleaning
Cleaning the casing
The casing may be cleaned with a damp cloth. Sticky dirt or contamination may be removed with a commercial, non-aggressive cleaning agent. Cleaning agents that contain chlorine must not be used.
Cleaning the heat exchanger
Personnel:
- Trained personnel
Protective equipment:
- Industrial safety helmet
- Safety shoes
- Protective gloves
-
Remove the induced air grille,
Fig. 12: Cleaning the heat exchanger
-
Carefully clean the heat exchanger with an industrial vacuum cleaner. Be careful to not damage any blades. We recommend using a soft brush with the suction inlet for cleaning.
-
After cleaning, reattach the safety cables, and screw-fix and close the grille.
CAUTION!
Danger of head injuries from the fall of the induced air grille!
