Exhaust compensation valve

Positioning of the exhaust compensation valve
with access hatch

3.3. EXHAUST COMPENSATION VALVE (MCP 125)

The valve is located in the final duct that serves the exhaust compensation unit (in the kitchen). It is
therefore in Ø125 mm. This product is specific to Aereco system.

The valve can be positioned in any direction, the maximum length being 232 mm.

However,

attention must be paid to the direction of the airflow in the valve:

an arrow marked on the

valve indicates the correct position.

Check the good quality of the pressure pipe before carrying the

installation. The pressure pipe must not be crushed.

The valve must be placed in the duct, at a minimum distance equivalent to 3 diameters (38 cm for
a 125 mm duct) from any fittings, and from the compensation unit.

In addition, there must be an inspection hatch to access the valve for maintenance.
