WARNING
Risk of scalding from suddenly escaping hot cooling water
The turbopump water connections are open to both sides. When connecting the cooling water supply,
there is a risk of scalding from suddenly escaping, hot cooling water at over pressure.
► Prior to installation, ensure that pressure is discharged from the cooling water system, and that it
is cooled down.
► Wear protective equipment, e.g., safety goggles and gloves.
Recommendations for cooling the turbopump
► Use additional cooling in the event of increased fore-vacuum pressure (> 0.1 hPa).
► Use additional cooling if operating with high gas throughput.
► Always use water cooling at ambient temperatures > 35 °C.
