Ancillary equipment, such as hose, gate valves and Y-pieces, is unloaded from the
main module and taken to the scene of operations on a sack truck.
Once the Hydrosub module has been placed in position the crew open and secure side
curtains to reveal the HFS 3000 submersible pump.
The Hydrosub module is powered by a Volvo diesel engine with a pre-heat sequence
which is started from the control panel. Three seconds before the engine starts an
audible alarm sounds and the amber warning beacon operates. The 125 litre fuel tank
is sufficient for 5 or 6 hours pumping before refuelling is necessary. Work lights
on manually extended telescopic masts are provided together with a blue warning beacon
which aids other firefighters in identifying the location of the unit and, especially
in remote locations, reminds them that it and its operator are there.
