Before commencing helium filling:
• Remove the transport kit.
• Re-configure the magnet venting (operational configuration).
• Connect the quench pipe.
NOTE
Use the DISPLAY button on the MSUP hand-held display to
scroll through the parameters.
If Magnet Display Unit does not indicate a liquid helium level:
• If the helium level reading is zero, the bottom carbon resistors should be checked with
the MSUP hand-held display (parameters 4 and 5).
NOTE
Inform Magnet HSC immediately. A bottom helium fill may be
required. Refer to Installation - Startup - Filling for more information.
Checking Magnet Temperatures
• Use the MSUP hand-held display unit to measure:- Helium level values

If the magnet was shipped by air with liquid helium in the helium container, the ventilation
valve is also equipped with an excess-pressure valve. This ensures that the pressure in
the helium container remains above the atmospheric pressure.
The correct transport configuration is shown below. Note that the 16psia outlet flex line
is not connected to the manifold. Split rings and seals are supplied in plastic bags for
use when the kit is removed.
NOTE
The copper seals for ventilation and turret connections are
only used once. After opening one of the clamps, these seals

Depressurization procedure
WARNING
Risk of asphyxiation
Failure to observe the following safety warning may result in
personnel experiencing dizziness or loss of consciousness
while working with cryogen.
¹ Do not vent helium gas into the magnet room. As an
exception, helium gas may be vented to cool the
syphon.
¹ Ensure that the turret venting kit is connected to the
quench pipe or exhausts to the outside.
¹ When venting to the outside, ensure the vent line is
positioned and secured in a safe manner.
• Connect the depressurization line
(from the customer site box) to the
16 psia valve flexible outlet.
• Run the free end of the depressurizing line to a connection for on-site
venting, or to the outside.

NOTE
FAILURE to close this valve before depressurizing will result
in excessive cooling of, and damage to, the cold head.
• Partially open the system bypass valve. (2/Fig. 101 / p. 81)
¹ Pressurized gas is vented slowly outside the suite through the depressurization line.
NOTE
The rate of depressurization is restricted by the bypass
valve; depressurization could take up to 2 hours.
The helium vessel is depressurized, therefore a large amount
of liquid helium will be boiled off.
NOTE
Siemens
Depressurization could take up to 6 hours or more. Attempting to do this more quickly will result in a significant loss of
liquid helium.

Post-positioning steps
• Depressurize until the helium vessel pressure is between 15 and 16 psia (1.3 psig).
• Close the system bypass valve. (3/Fig. 101 / p. 81)
• Warm the joint and remove the depressurization line from the 16 psia flexible vent
line. (Fig. 100 / p. 80)
CAUTION
Cryogenic liquids.
Failure to observe the following safety warning may result in
cold burns.
¹ Protective clothing, gloves, and eye protection must be
worn.
• Defrost the turret.
• If all of the other checks in Table 1 are ‘YES,’ the 16 psia valve may be faulty.
(Tab. 2 / p. 74)
• To replace the 16 psia valve, contact Magnet HSC.
• After depressurization, the airfreight kit can be safely removed. Refer to (Removal
of Air Freight Kit / p. 75).

• Attach the cables securely so they cannot shift.
• Route an additional cable harness, if necessary.
NOTE
You are permitted to cross cables at one or two places near
the filter plate, on the cabinets, or at the magnet. The cables
must be positioned as far away from one another as local
conditions permit. In all cases, the distance between the
cables in the cable duct must be 300 mm. If possible, use
existing materials.
NOTE
Keep the individual cables separate, i.e., tie the gradient
cables, RF cables, the signal and power cables separately
(minimum distance 300 mm). DO NOT TIE ALL CABLES
TOGETHER!
NOTE
In case of remaining cable lengths: Do not coil up the remaining cable lengths. Instead let excess cable lengths meander

Test running the compressor before startup
The compressor must be operated for 10 minutes to clean up any oil migration incurred
during transportation, BEFORE the helium lines and cold head are connected. For this
test, only the water and power connections are required.
• Check the transformer voltage
taps are correctly selected to match
the supply voltage.
• If required, remove the plastic
cover(3), re-position the tap and
replace the cover.

NOTE
The unit is configured in the factory to 400V3~50Hz.
NOTE
If the compressor is wired for 400 V3~50Hz, connecting to a
higher voltage may damage the control circuit.
• Ensure the ICS cabinet is connected to the water supply and return, and that the
water is turned on.
• Ensure the compressor water shut off valves are open, and water is flowing through
the compressor.
