3. INSTALLATION

3.3.3 Condensed water outlet

Drainage from the condensate tray is taking place through a connection in front of the
inspection side through the cover panel. On a XWPRSS unit will be three condense outlets,
two on the exhaust side (negative pressure) and on the supply side (positive pressure). On
XKS and XK units we will see one outlet on the exhaust side (negative pressure). There are
two different types of water traps available.
Drain trap with ball valve
This drain trap should only be installed where there is negative pressure in the drain system
as the ball valve will open on positive pressure. The inserted float ball prevents the intake of
air under dry operation, where in a traditional drain trap you have to refill water to avoid air
been sagged into the unit. At the same time you need less space in height than on a traditional
drain pipe. This drain trap can be used up to -900 Pa.
Normal drain pipe
The normal drain pipe with screw cap for filling with water and check can be used for negative
and positive pressure. The length of the pipe can be calculated the following way.
Positive pressure
Negative pressure : H1 = ∆p + 50 mm
∆p = pressure in mm WS (100 Pa = 10 mm WS)

3.3.4 Damper motors

All damper motors, except in the mixing module, are installed, prewired and connected to the
terminal strip of the XWPRS or WP. The prewired damper motors in the mixing module must
be connected to the terminal strip of the XKP or WP module after the installation of the unit.
You will find the 3 pole wiring cable inside the mixing module. For further information see the
electrical diagram of the unit.

3.3.5 Filter gauges

The filter gauges for outside and return air are mounted at the front of the XWPRS or WP
module and prewired to the terminal strip.
After assembling the unit the pressure tubes have to be connected to the probes in the filter
section. You find the pressure tubes, which are marked – and +, inside the main section. Run
the pressure tubes inside the cable channel to the filter section and connect the + tube to the
probe behind the filter and the – tube to the probe before the filter.
H2 = ∆p + 50 mm
: H1 = 50 mm
H2 = ∆p / 2 + 50 mm
