➡
Place the pump on its high vacuum flange
(Caution: do not damage the sealed surfaces).
➡
Pull out the synthetic feet from the base of the pump.
➡
Screw air cooling to the holder 37 with 4 srews M8 and
spring washers onto the turbopump. The fan have to be
installed parallel to the electric connection.
Connection to the cooling water mains
➡
Fit the dirt trap (Accessory) in the supply line.
➡
Connect the supply line with hose clips onto one of the two
cooling water connections.
➡
Connect Cooling Water Monitor TCW 002 in return line.
➡
Connect the return line to the other cooling water connec-
tion of the turbopump.
➡
Tighten all hose clips and check for firm seating of the
hoses.
➡
Tighten the hollow screws on the cooling water
connection to a torque of 20 Nm.
Electrical connection, air cooling
➡
The electrical connection of the air cooling unit is made on
the control line 57 (please see Section 3.8.) on the connec-
ting cable TCM-turbopump (see the operating instructions
for the TCM 1601, PM 800 478 BN).
Alternatively, either the casing heating unit or the TMS can
be connected to the control line. Simultaneous operations of
the functions is not possible.
3.5. Connecting The Venting Valve
Uncontrolled venting can cause overloading on
the axial bearing resulting in activation of the
safety bearing.The TMH/TMU 1600M may only
be vented via the venting valve fitted. It must
not be replaced by other venting equipment.
Maximum pressure on the venting valve: 1.5 bar absolute.
If a higher venting rate is required further venting
components can be opened as soon as the rotation speed of
the pump is less than 100 Hz.
If, from the beginning, the pump is to be vented with
equipment other than that fitted, the pressure increase on the
high vacuum flange must be limited to 2 mbar/s until the rota-
tion speed is less than 100 Hz.
Electrical connection, venting valve
The electrical connection of the venting valve is via the
connecting cable magnetic bearing controller - turbopump.
➡
Connect the plug from the cable junction to the venting
valve and secure with screw.
Please also refer to the connections diagram for the
TCM 1601 in Operating Instructions PM 800 478 BN.

Air Cooling (Accessory)
Air cooling is only permissible where the
ambient temperature is < 30 °C.
Ensure that the supply and exhaust air ducts
are not restricted.
Fitting the air cooling unit
➡
Place a fluff-free and clean pad on the working surface.
