3.5.5 Installation of the electrical harness of the fuel pump.
If the length of the wiring harness of the fuel pump needs to be shortened, it is
permissible to remove the unnecessary portion from the middle of the harness.
The connection point must be insulated.
Never connect the fuel pump to a continuous DC power supply. It will burn the
coil of the fuel pump.
Installation of the electrical harness connector of the fuel pump is shown in Fig.26.
Make sure that the wiring of the fuel pump is installed in the right way before inserting
the pins of the wiring in the plastic casing.
Make sure the pins are inserted all the way to the end and that they lock securely in the
plastic casing. When correctly inserted, a small click can be felt. The polarity of the pins
does not matter.
3.6 Installation of heater wiring.
Install the electric harnesses of the heater according to the diagram of heater
electrical connections. (see Annex.4).
When installing electrical harnesses avoid all possibility of them being heated.
Install all the wire harnesses and electrical elements in dry and protected places. No
deformation or wire movement is permissible when the vehicle or vessel is operating.
IMPORTANT!
Fuses must be removed before installing electrical harnesses.
The battery of the vehicle or an auxiliary battery powers the heater. Control the
charge of the battery on a regular basis. It is recommended to disconnect the heater from
the battery to avoid discharge during long dockage or storage of the vessel or vehicle. Do
not disconnect the heater from power before the purge cycle ends.
The heater must be connected to an uninterrupted power supply at all times. Cutting
the power to the heater will result in loss of settings (clock, operation mode and settings).
If the heater is connected to an existing electrical installation, the wiring should be
of sufficient diameter to prevent a voltage drop (main cause of error 15). It is always
recommended to connect the heater directly to the battery of the vehicle/vessel or
auxiliary battery. It is strongly recommended to use new and provided wiring for
installation of the heater.
