Page 8: System Installation
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. 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. - Page 9 Drawing 1420C...
- Page 10 Power Up Guide For the first time, or after an extended period of being disconnected from the main supply, the unit should be left powered on whilst the internal ‘dryfit’ battery and Envitec batteries are charged up - ideally overnight. However, we recommend that the unit is left on permanently. The Envitec screen will display an animated battery charging symbol (See Fig 1).
- Page 11 Power Down Guide The system can be left running 24/7. If the user requires the system to be powered down, either due to an alarm condition or power saving over a long weekend when O2 monitoring is not required, then a shutdown procedure must be followed to avoid flattening the internal batteries.

Page 12: Maintenance
Important It is recommended that the filter and fuel cell sensor are replaced every 6 months. The replacement kit (Ref: MR106) may be obtained directly from Wardray Premise Ltd or in overseas countries from our local agents. When switched on the fuel cell cable plug has a voltage on its terminals (to power the fuel cell), which must not be allowed to touch the chassis if left disconnected. - Page 13 Medical Oxygen Sensor Fuel Cell Fuel Cell cable connector Ease out gently here HEPA Vent Filter O2 Sensor ‘T’ Piece Housing Fig 1 Fig 2...
