3. INSTALLATION
3.3.5 Flow gauges for centrifugal fans
The flow gauges for centrifugal fans are mounted at the front of the XWPS, XKS or XK
module and prewired to the terminal strip of the module.
After assembling the unit the pressure tubes have to be connected to the probes in the fan
section. You find on pressure tube for each fan inside the main section.
Run the pressure tube inside the cable channel to the fan section and connect the tube to
the probe on the low pressure side of the fan.
3.3.6 Temperature sensors
All temperature sensors in the unit are mounted and prewired to the terminal strip of the
XWPS, XKS or XK module.
Only the supply air duct sensor has to be installed after assembling the DanX unit. You find
the coiled up duct sensor near the connection panel of the XWPS, XKS or XK module.
The supply air duct sensor is installed in the supply air duct after the heating coil in the
following way.
Drill an 8 mm hole in the supply air duct about 1.5 m from the unit.
•
Place the sensor in the hole.
•
Fasten the sensor housing to the duct with two screws.
•
3.3.7 Humidity sensor
The humidity sensor is a room or duct mounted sensor, depending on what has been
ordered. You find the humidity sensor separately wrapped inside the electrical panel.
The duct humidistat is installed in the following way:
Drill a 15 mm hole in the return air duct about 1.5 m from the unit.
•
Fasten the sensor housing to the duct with two screws.
•
Connect the sensor directly to the electrical panel.
•
The room humidistat is installed in the following way:
Find a suitable place for the sensor in the swimming pool hall. Avoid placing the
•
sensor in direct sun light or near the supply air duct.
Place the humidistat in a height of about 2.5 m to avoid direct influence from wet
•
people passing the sensor.
Fasten the sensor housing to the wall with two screws.
•
Connect the sensor directly to the electrical panel.
