Room Planning and Pre-Installation
Cooling-water Supply
In order to supply the S4 PIONEER with cooling water, a connection must be made to the mains water
supply with a discharge.
Cooling water supply
Flow rate
Difference pressure
(= difference between input and pressure-free output pressure)
Water temperature
WARNING
The pressure of the main water supply must not be higher than 7.5 bar. If the local water pressure
exceeds this value, then a water pressure reducer must be provided!
The cooling water should be low in suspended matter. A suitable filter must be installed in the inlet
line. It is recommendable to connect two water filters in parallel if the water is highly contaminated.
The devices then need not to be switched off in order to clean one of the filters.
The water valves are only opened if necessary. As a result the water consumption is reduced to a
minimum.
If a sufficient tap-water supply is not available an external cooling-water unit with a closed water circu-
lation can be used. In this case it must be considered that the water flow is not continuous. It can be
necessary to install a bypass.
Two hoses of NW 1/2" must be used for connecting the cooling-water unit to the X-ray generator. The
maximum permissible length of the hoses is 10 m each. They must be fixed using hose clamps.
3/4-inch piping of copper or galvanized steel must be used in the case of larger distances. The maxi-
mum length is 15 m per pipe. The ends must be provided with hose unions. Short hoses NW 1/2" are
used to connect the X-ray generator and the cooling-water unit. The maximum permissible difference
in height between the cooling-water unit and the X-ray generator is 6 m.
