System Installation
Please note: This unit is specifically designed to monitor oxygen levels within the MRI
Scanner room safely from within the control room.
Unpack the items and check against the packing list.
1.
Position the Oxygen monitor in a suitable location in the MRI Control Room to allow the end
user to be able to see the LCD screen and, under fault conditions, hear the audible alarm.
2.
If not already fitted remove the back of the unit by undoing the six Philips screws and fit the
Sensor Cell and HEPA Vent Filter (See Page 12). Replace the back.
3.
The power supply unit is plugged into the DC input socket (on the back of the unit Fig 1) and
the mains plug inserted in a suitably positioned wall socket.
4.
Connect the PVC flexible hose to the chromed
‘
Air Inlet
’
nozzle on the back of the unit (Fig 2).
5.
The other end of the flexible hose should be routed through a suitable open wave guide into
the MR Scan room, allowing the hose to be routed to the close proximity of the cold head of
the MRI scanner. This is usually within the suspended ceiling cavity and secured in place
along the run with cable ties. Any excess tubing should be cut off.
(see Drawing 1420C on page 9)
The unit can now be switched on at the mains.
Please see page 10 of the Manual for final power up guidance.
