Function

The air is supplied horizontally into the space through the perforated front panel of the diffuser.

The supply air pattern can be deflected radially in the different directions desired (1, 2, 3 and 4) with separate deflector panels (delivered as accessory).

Diffuser can also be used as an exhaust unit.

 The recommended maximum temperature difference between supply and room air as follows:

  • 8 0C for 4- and 3 –way air supply direction
  • 6 0C for 2- and 1–way air supply direction

Installation




Fig.1. Installation above list                       Fig.2. Installation under list
 

The diffuser is available in size 595x595 for direct installation to the modular T-bar ceiling (600x600).

Ceiling installation for standard sizes can be made above or below T-bars (Fig.1. and2.).

The diffuser is connected either direct to the duct by screwing or riveting, alternatively to the Halton’s balancing plenums Halton TRI or Halton TRH.

Direct the flow pattern in the desired directions by installing the deflector panels on the perforated front panel to meet the required specifications (4 way direction in standard delivery, see Fig.3.).

Installation with plenum 

The collar in Halton’s TRI can be installed either internally or externally on the bottom of plenum. The height of unit is presented in the tab Dimension.

A recommended minimum safety distance upstream of the plenum is normally 3 x duct diameter.

The technical performance for the combination of Halton Jaz Rain Ceiling diffuser and Halton plenum is presented separately for different installations.

Opening the diffuser

Open the front panel using some suitable thin material (like plastic sheet - Fig.5.). Push the sheet on the slot between front panel and chamber on the side where the Halton logo is located (distance about 50 mm from the corners). Pull slightly to open the front panel.

Detach the open front panel by pressing the hinge from inside (Fig.6); reassembly it by pulling it against the hinges.

Close the front panel by pushing it until the springs lock.

Adjustment

Halton Jaz Rain Ceiling diffuser does not include any separate airflow adjustment.

In order to enable the adjustment and measurement of airflow rate it will be recommended to connect the diffuser to Halton TRI or Halton TRH plenum. The supply airflow rate is determined by using the plenum’s measurement and adjustment module.

Open the diffuser’s front panel and pass the tubes and control spindle through the hole in perforation. Close then the front panel.

Measure the differential pressure using a suitable manometer. The airflow rate is calculated using the formula below

 
 

TRI > 8xD min. 3xD
100 6.0 7.5
125 9.9 12.6
160 16.9 21.9
200 28.3 32.0
250 47.9 51.5
315 78.6 -

 

TRH > 8xD min. 3xD
100 6.5 7.5
125 10.8 12.6
160 19.4 21.9
200 29.7 31.0
250 48.8 51.5

       

Adjust the airflow rate by rotating the control spindle until the desired setting is achieved. If needed lock the damper position with the screw in module.

Replace the tubes and spindle into the plenum.

Servicing

Detach the front panel of the diffuser and let it balance on the hinges.

Wipe the diffuser casing and front panel with damp cloth. Ensure that the deflector panels are directed as requested. After cleaning reattach the front panel.

 

Option with balancing plenum  

Remove the measurement and adjustment module by gently pulling from the shaft; not from the control spindle or measurement tubes. Wipe the components with damp cloth instead of immersing in water. Wipe also the inner part of the plenum; detach the attenuation material if needed.

Reassemble the module by pushing the shaft until the unit meets the stopper.

Push the front panel back into casing so that the springs lock.
