The nozzles of the diffuser direct the airflow obliquely toward the ceiling surface. Cover sleeve Cover sleeve for exposed installation (only for TLD/B plenum) The supply air pattern can be directed by rotating the nozzles. Direction of the supply air jet does not affect the pressure drop or the airflow rate. The recommended maximum air temperature difference between supply and room air is 8 0C. The maximum recommended operating temperature for the plastic material is 60 °C. Note: The airflow pattern data has been prepared for a wall installation with a distance of 200 mm from the ceiling...

diffuser section Plenum CODE DESCRIPTION Measurement and adjustment module Do not fasten screws or rivets in the section at The recommended installation distance below ceiling distance K1 from the front edge of the plenum, in order to keep the section clear for diffuser section (1) fastening. Installation opening The recommended minimum safety distance before the supply unit is 3xD (D = duct diameter). TLD - Wall Diffuser Unit 246

The supply flow rate is determined by using measurement and adjustment module MSM. The tubes and control spindle are passed through the nozzles of the diffuser section, which is then replaced. 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 diffuser section. The k factor for installations with different safety p distances (D= duct diameter) is as follows. ^ The...

Product code Open the diffuser section, and remove the measurement and adjustment module by gently pulling from the shaft (not from the control spindle or measurement tubes). Diffuser section Wipe the parts with a damp cloth, instead of TLB Plenum (with MSM module) TLB Plenum (without MSM module) Reassemble the measurement and adjustment TLC Plenum (with MSM module) module by pushing the shaft until it meets the TLC Plenum (without MSM module) stopper. The diffuser section is replaced by pushing it into the D = Diameter of duct connection plenum until the springs lock. Suggested...
