4.6.5 Installing the check valves
Note: An inlet check valve can be installed incorrectly in an outlet
check valve position, and vice versa. Make sure that the check
valves are installed in their correct positions.
If cleaning of the check valve as decribed in section 4.6.3 Cleaning the
check valves does not correct the fault, replace the check valve with a
new one.
The check valves are of four different types (see Fig. 4-1):
– Inlet check valve short (1 pc.)
– Inlet check valve long (2 pcs.)
– Outlet check valve short (2 pcs.)
– Outlet check valve long (1 pc.)
The inlet check valves have line-shaped holes.
The outlet check valves have round holes.

inlet (lower) port on the connection part, and the outlet
check valves next to the outlet (upper) port.
2 Fasten the check valve using the screwdriver.
3 Reinstall the connection part according to section 4.4.3 Installing
the connection part.
