INSTALLATION
Power must be cut off before carrying out any
installation, maintenance or removal opera-
tion.
DANGER
The oil supply (Suction 1) (Fig. 5) blanking plug is
made from plastic material. Once removed this
should be discarded and not reused under any cir-
cumstances.
WARNING
In single pipe installations the plug supplied in the
return line 2) of the pump is made from steel.
IT IS VERY IMPORTANT that ONLY the steel
plug is used for this purpose.
To replace it:
replace the connection 3) supplied as standard equipment;
block the pump by uniformly tightening the 3 screws 1)
(Fig. 6) - recommended tightening torque 3 ± 0.3 Nm.
Before beginning to use the new RIELLO pump:
check the disassembled pump for any dirt.
WARNING
Proceed as follows:
loosen and remove the 4 fixing screws 2) (Fig. 6) of the
cover 4) and check the condition of the fuel filter.
If there is dirt on the inner surface of the pump body, cover
or filter, then the fuel tank and relative piping are probably
contaminated. Corrective action (cleaning) is therefore nec-
essary
you are advised to use an additional, good quality filter (with
a filtering capacity of max. 15 micron), to be installed on the
power supply line.
