Function


FUNCTION




Supply air is divided into several jets through the cones.
The divergent sections of the diffuser create negative pressure below the diffuser so room air is induced into the supply air device. Room air and supply air mix.
This internal induction reduces temperature and the air velocity into the space.
The process is the same outside the diffuser between the supply and mixed room air, with external induction further reducing velocity and the temperature difference between supply and room air.
This effect reduces the flow disturbances .

The diffuser can also be used as an exhaust unit.

Installation


INSTALLATION




CODE  DESCRIPTION
1  TCM
2  PLC PLENUM

The TCM diffuser can be installed flush with a suspended ceiling or fully exposed in the space.
The diffuser is connected either directly to the duct or using a PLC plenum or TRI balancing plenum.
When it is connected directly to ductwork, a safety distance of minimum 3D upstream of the diffuser should be maintained.

Adjustment


ADJUSTMENT


The airflow rate can be adjusted and measured only when the diffuser is installed.

In order to enable airflow adjustment and measurement of airflow rate, it is recommended that the diffuser be connected to a plenum equipped with the MSM module.
The supply flow rate is determined using measurement and adjustment module MSM.

Detach the conical central core and pass the tubes and control spindle through the diffuser.
Measure the differential pressure with a manometer. The flow rate is calculated using the formula below.


Adjust the airflow rate by rotating the control spindle until the desired setting is achieved.
Lock the damper position with a screw.
Replace the tubes and spindle in the plenum and push the conical central core back into place.

Airflow adjustment damper DD

The airflow rate is adjusted by turning the damper blades behind the diffuser with a screwdriver. The measurement is carried out when the diffuser is installed.

Servicing


SERVICING


Remove the conical central core by gently drawing it out by the central panel (simultaneously, a small pin on the inner side of the external cone is pushed and the assembly is turned clockwise, until it comes free).
Clean the parts by wiping them with a damp cloth.
Push the conical central core back into place so that the springs lock.

Option: with balancing plenum TRI + MSM or PLC + MSM

Remove the measurement and adjustment module by gently pulling the shaft (not the control spindle).
Wipe the parts with a damp cloth, instead of immersing in water.
Reassemble the measurement and adjustment module by pushing the shaft until the module meets the stopper.
Push the conical central core back into place so that the pin locks.
