6.13 Mixing valve
Mixing valves which are optimally matched to the units are available for easy
installation of RoofVent
®
units. They have the following specifications:
■
3-way mixing valve with modulating rotary actuator (run time 9 s)
■
Flow characteristic:
–
Equal percentage control path
–
Linear bypass

Integrated position control and response
6.14 Condensate pump
The condensate pump is installed directly under the condensate drain connection;
the supplied container is prepared for installation on the Air-Injector. It pumps
the condensate through a flexible hose to a delivery head of 3 m, thus enabling
discharge of the condensate
■
through waste water pipes directly below the ceiling,
■
onto the roof.
