Accessories and Options
The VFOCS hose burst pressure switch can be mounted either onto the filler/breather tube or
direct to the back of the casing depending on the pump size (see Fig.23 below)
There is also the option to fit an add on vent kit which via a copper tube, allows the pump to
breath and reduce running temperature, but does not affect the signal to the switch during hose
burst

Fitting Instruction:
There are two types of installation, one is mounting to the filler/breather tube and affects the
VF10 to VF25 inclusive, as the switch body can interfere with the mounting frame. The other is
a direct mounting onto the rear case, which covers the rest of the pump range from VF32
upwards
Filler /Breather tube mounting:
Remove the plastic plug from the standard filler tube, then fit the brass compression fitting to the
filler tube using the pipe nut and collar and tighten the nut, so as to crimp the fitting onto the pipe
(tighten the nut until the fitting does not rotate and then a further ½ a turn, to avoid over-
tightening!)
This allows a ½” male to ¼” female reducer to be fitted which allows either the VFOCS pressure
switch or the optional tee piece and vent tube (see additional notes below) to be fitted first & then
the VFOCS switch to complete the assembly
Direct case mounting:
The ¼” bsp female reducer for the pump is simply fitted and this allows either the VFOCS
pressure switch or the optional tee piece and vent tube (see additional notes below) to be fitted
first & then the VFOCS switch to complete the assembly
