HYDRAULICS
Inlet transit gaskets must be discarded and replaced with suitable new gaskets at
the time of installation.
Refer to Part D “Servicing” 1.4 for target torques for gasket sealing.
If the dispenser has been in storage for longer than 3 months, the following checks
and actions must be carried out during the installation and commissioning process:
a Hoses - Visually check over each hose and ensure no kinking has occurred;
b Nozzles and swivels - Check that the swivels on each hose move freely through a full
range of movement. Check that the rotatory joints are free and not seized;
c Head - Visually inspect the interior of the head for any signs of moisture or
condensation. Inspect all PCB’s for any sign of corrosion. Remember to also check
the Multiplexer Board which is usually located underneath the top panel of the
Hydraulic Cabinet;
d Vee Belt (pumps only) - Check the Vee Belts for any permanent distortion or
delamination due to sticking to the pulley.
3.1 Pumps
Fuel lines in are connected to their respective pumps by means of flex-connectors. To
facilitate ease of installation, motors may be temporarily removed and the tension of the
drive-belts adjusted upon replacement.
3.2 Dispensers
Fuel lines in (from one or more submersible pumps) are connected to their respective
meters by means of fixed piping via a shear valve chosen and supplied by the installer.
3.3 LPG
The LPG return valve is not attached to the hydraulic cabinet in order to allow it to be
placed in the best position.
Additional LPG Information may be found in Part C “Commissioning” - Section 7 LPG
SECTION.
3.4 Vapour Recovery
Vapour Recovery (VR) components are common throughout the Gallagher PULSE range.
Integral models are equipped with their own vapour recovery pump. This pump’s vapour
line should be connected to underground vapour lines by means of a shear valve.
All VR models in the PULSE range have vapour recovery pipes and hose components fitted
prior to despatch.
A separate Install/Commissioning Manual for VR2 equipment is available, part number
2A03039
