Technical Information
High Temperatures
Hot Surfaces: Boiler temperatures reach 530 °F (275 °C) which can cause
serious burns. Always ensure that surfaces have cooled to near room
temperature before touching them.
Hot Cooling Water and Steam: The water used to cool the pump can reach
scalding temperatures. Touching or rupture of the cooling surface can cause
serious burns. Water left inside Quick Cool coils from previous use turns to
steam when the pump is reheated. This steam must be allowed to escape
without contacting personnel. Whenever possible, design the water system
with interlock valves so that power cannot be applied to the pump unless water
is flowing in the main cooling coils (not Quick Cool coils).
High Voltages
Diffusion pump heaters operate at voltages (up to 480 V) high enough to
kill. Design systems to prevent personnel contact with high voltages.
Securely attach prominent hazard warnings. Personnel should always break
the primary circuit to the power supply when direct access to the heater or
wiring is required.
Large Equipment and Heavy Weights
The lifting and moving of large diffusion pumps requires power-assisted
equipment and the use of trained moving and installation personnel to avoid
dropping, slipping, and overturning the pump. Pumps weigh in excess
of 500 lbs (226.8 kg) and are 3 to 6 feet in their largest dimension (1 to 2
meters). Their mishandling can cause severe injury. Check the weight of the
equipment before lifting and assure that the power-assist device is adequate
for the task. Do not stand under the equipment being lifted and moved.
