5.6.6 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.

5.6.7 Distance from the radiator to the unit
The coolant water pump mounted on the generator is so laid out that a maximum distance of up to 5 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).
5.6.7.1 Minimum hose diameter for cooling lines:
Panda 04 kW .................... Ø18mm (¾")
Panda 06 - 20 kW .................... Ø25mm (1")
Panda 25 - 30 kW .................... Ø32mm (1¼")
Panda 40 - 50 kW .................... Ø38mm (1½")
Panda 50 - 60 kW .................... Ø44mm (1¾")
5.6.8 Coolant expansion tank
It is absolutely essential, that a exoansion tank, that can be aerated, is fitted adjacent to the radiator. The ventilation
pipe should, if possible, be fitted to the radiator’s highest position. For this, a pipe with a maximum diameter of
10mm suffices, which must be fed to the expansion tank. A further pipe, which must be fitted to the floor of the
expansion tank, can be fitted to the cooling system in any desired place (i.e. T-piece). Frequently a connection is
provied on the radiator itself. The coolant expansion tank is not normally supplied by Fischer Panda. For this a stan-
dard vehicle expansion tank is the most suitable. Vehicle accessory range is the most suitable.
