3. INSTALLATION
8
It is very important to remove the small rubber plug inside the valve; otherwise the valve
cannot work with overpressure! Secondly the arrow with PA+ has to show in the direction
of the drainage!
3.5 Installation and connection of components
All components and duct work of the air handling unit must be installed correctly before
starting up and commissioning the DanX unit.
Installation and connection work should only be carried out by trained professionals
or by
people supervised by authorized staff. It is the responsibility of the fitter to read and
understand this guide and other given information.
All temperature sensors are ready mounted and wired to the control panel, just the supply air
temperature sensor and return air temperature / humidity sensor have to be installed in the
duct system.
3.5.1 Condensed water outlets
Drainage from the condensate tray
(1”) takes place in two outlets, one on the exhaust side
(positive pressure, outlet on the side) and one on the supply side (negative pressure, outlet
in the front).
Normally it is only necessary to connect the drainage from the exhaust air side. We
recommend using our special ball valve to avoid that humid air is blown through the outlet
into the technical room.
Remove the small rubber plug inside the valve!
The drainage on the front of the unit (supply side) has been blocked by the factory as only
very little condensate will appear on that side of the heat exchanger and this small amount of
condense will then evaporate again into the airstream. If it should show that more condense
then normal is produced, it is possible to remove the plug from the outlet and connected the
outlet with the help of a ball valve to the drain. If you connect a ball valve to this outlet it is
important that the arrow with PA- has to show in the direction of the drainage, as the supply
side works with under pressure!
When using a ball valve on the under pressure side the small rubber plug inside the valve
should not be removed!
