Removal of a condenser fan
WARnIng
Risk of injury by burns and rotation
The electronics housing can get hot.
The fans have an operation delay after the unit is stopped !
You need an appropriate secured access (e.g. working platform) to the chiller top, to dismount a condenser fan
for each heat exchanger element.
• open the centrally located cable duct on top of the chiller.
The duct is divided into a part for the power lines and a narrower part for control lines. The fan is connected by
a screwed plug connection in the power line part and two screwed plug connections in the control line part.
• disconnect the electrical connections and protect them against damage and humidity.
• completely unscrew the 4 Torx screws of the fan grille
• lift the fan (weight: approx. 30 kg) with another person and place it upside down on a fan next to it.
Condenser fan
The bearings of the fans are lifetime lubricated and do not need maintenance. Check the operation current.
An increased operation current indicates a winding short circuit in the fan motor.
Air filter in the compressor cabinet
• Check the filter in the air intake / outlet (see figure on page 21) in terms of pollution (visual inspection).
• Replace the filters (filter class G3) if necessary. The grilles are held by plastic clips and can be removed
using a screwdriver.
