Do not install the MTD-ERV 350 with a side against a wall to avoid possible contact noise.

The air ducts to be connected, minimum diameter 150mm,mustbeinstalledwithaslittleairresistance as possible and air tight.

4.3Wall Mounting

•Insulate the outside air duct and the stale air duct vapour-tight between the roof/gable opening and the MTD-ERV 350. This prevents the formation of condensation on the outside of the ducts.

•Install the exhaust air duct with a gradient to- wards the MTD-ERV 350.

4.3.2 Connection of the Condensation Drain

Install the MTD-ERV 350 on a wall with a load-bear-				ion
			Connect
ing capacity of at least 200 kg/m².
For other walls we recommend the use of a base for
installation on the ßoor (available as an option, see
section 4.8 with service parts). This helps to avoid
the transmission of structure-borne noise.
¥ Fasten the supplied mounting bracket to the	MTD-ERV 350	LEFT
wall horizontally.

¥Connect thecondensationdrain(notsupplied) to the underside of the MTD-ERV 350.The value shown of 235 mm is only an indicative value. The actual value depends on the type of con- densationdrainselected,seealsosection4.3.2 for the connection of the condensation drain.

¥Ensure that at least 1 metre of space is left in front of the MTD-ERV 350 for later maintenance work.
