altitude and the room temperature increase (the drop is approximately 3.5% for every
305m / 1000 ft above sea level and 1% for every 5.6°C/42°F above 16°C/61°F). Refer to
the combustion engine’s instructions for any precautionary steps to take if the appliance is
to be used at high altitudes or at high room temperatures.
Refer to figures 1, 2, 3 and 4 located at the start of these operating and maintenance instructions
for the following.
2.1 IDENTIFICATION OF PARTS
2.1.1 Trolley/Barrow parts
2.1.2 Motor-driven pump parts
2.2 SAFETY DEVICES
Pressure limit/adjustment valve
This valve has been correctly set by the Manufacturer and enables adjustment of the operating
pressure and the pumped fluid to return to the by-pass hose, thus preventing the creation of
dangerous levels of pressure when the delivery outlet is closed or should pressure be set that is
above permitted levels. A pressure limit/adjustment valve complete with interception/distribution
devices for the pumped liquid (for example taps) is usually called a
pump control unit.
For
simplicity’s sake, these instructions use the term
control unit
to refer to both the pressure limit/
adjustment valve and the pump control unit.
