Function

Supply air is supplied through the linear slots of the diffuser horizontally along the ceiling surface or vertically into the occupied zone.
For wall installation, the plane jet air is supplied horizontally or directed to the ceiling surface, which increases the throw length.

For an exhaust application, the diffuser is supplied without flow control vanes.

Installation

Code description
1.     Mounting bracket
2.     Transversal bar
3.     Screw

The Halton SLL linear slot diffuser is connected directly to the Halton PLL or Halton PLD plenum.
The plenum is installed into the suspended ceiling with M8 drop rods (not included in the delivery) and connected to the ductwork.

Remove the T-profiles of the Halton SLL by pulling them gently, in order to access the transversal bars located behind the profiles.
Fit the installation brackets into the grooves of the plenum and secure with the screws supplied with the unit.
Put screws into the holes of the transversal bars. Screw on until the diffuser is flush to the ceiling.
Replace the T-profiles.

The unit can be installed without plenum using the staff brackets. Those pieces are available as accessory (2 by slad or by linear meter).
 

String course mounting

The maximum length is 2000mm. So when length is superior to 2000mm, it is necessary to place side by side several pieces. Some alignement guides are given in order to make the the mounting easier.

Adjustment

The air pattern can be changed through 180° by adjusting the flow deflection vanes using a screwdriver. Each deflection vane section can be individually adjusted without removing the T-profiles in order to provide flexibility in supply air pattern orientation.
Diffusers are delivered unadjusted with the flow deflection vanes in the open position.
 

 

To aid in adjusting and measuring the air flow rate, it is recommended that the diffuser is connected to a plenum equipped with a MSM.
The supply air flow is determined by measuring the pressure difference with a measurement module.
Measure the differential pressure with a manometer. The air flow rate is calculated according to the following formula:
 

where:

∆Pm is the measured pressure (Pa)
is a factor given as a function of mounting and diameter
Qv is the airflow rate (l/s)

 

The k factor for installations with different safety distances (distance of other items from the MSM):

 

  Safety distance
NS > 6XD min 3XD
160 19 22
200 49 32
250 51 51


Adjust the air flow rate by rotating the control spindle until the desired setting is achieved.
Lock the damper in position with a screw.
Replace the tubes and spindle in the plenum, and return the linear diffuser to its position.

Servicing

Remove the T-profiles.
Remove the linear diffuser by unscrewing the screws of the transversal bars.
Clean the parts by wiping with a damp cloth.
Push the linear diffuser back into place by screwing the transversal bars to the installation brackets.
 

Option:
With balancing plenum Halton PLD + MSM/MEM or Halton PLL + MSM/MEM

Remove the measurement and adjustment module by gently pulling the shaft (not the control spindle or measurement tubes!).
Wipe the parts with a damp cloth, instead of immersing in water.
Reassemble the measurement and adjustment module by pushing the shaft back into place until the module meets the stopper.
Push the linear diffuser back into place by screwing the transversal bars to the installation brackets.
