Installation Instructions
Pay attention to the following item at the horizontal assembly of the radiator:
To avoid damages of the fan motor please bore some holes on the backside of the fan (diameter
approx 4mm). Because water can enter the fan (rainwater, condenswater, sweatwater etc.). The
water can run out through these holes. (see below 02) Generally a fan is a wearing part and
should be changed one time a year.

Distance from the radiator to the unit
The coolant water pump mounted on the generator is so laid out that a distance of up to 7 mtrs
length from the radiator is possible. The hose cross-section must be laid out accordingly. The
minimal internal diameter amounts to 18mm (Panda 4500). A hose must be used for both sides
(forward and back flow) which is resilient to pressure and high temperatures (at least 120° C).
Minimum hose diameter for cooling lines:
Panda 04 - 10 kW .................... Ø18mm (¾")
Panda 12 - 20 kW .................... Ø25mm (1")
