Temperatures
max. +80 °C [max. +176 °F] Temperature
of pumped
gases/vapors:
At higher fluid temperatures,
measures must be taken on
the system to prevent burns,
e.g. mount separating safety
device (cover).

liquid temperature
(see Fig. 2, Pg. 17)
When this temperature is
dropped below, the hose of
the liquid separator
(accessory) must be
connected to the connection
for cavitation protection
(Fig. 7, Pg. 25, Item 4).

If higher pressures can occur
in the system, then
corresponding protective
