V. GENERAL INSTRUCTIONS
1. Warranty
Unpack flowmeter and inspect to make certain that the unit has not been damaged
during shipment.
The unit’s serial number is located on the back of the flowmeter (see page 17 for
Newport's serial number location). Record the serial number in the area provided
at the back of this booklet. Note: After Cabinet Mount model is mounted into a cab-
inet, the serial number will no longer be visible. Always reference the serial number
when corresponding with Accutron.
Complete the warranty card supplied with flowmeter Ultra and mail to Accutron.
Completion of this step ensures proper device warranty coverage. Accutron
analgesia machines carry a two-year limited warranty (see Warranty on page 25
for details).
2. Gas Supply Connection
Always use clean, dry medical gases. Introduction of moisture or other contami-
nants into Accutron analgesia gas machines may result in defective operation.
After device installation, connect the oxygen and nitrous oxide supply lines to the
Diameter Specific Instant fittings or DISS fittings located on the back of the device.
See pages 15 and 16 for information specific to the Newport. It is important that the
regulators for both gases be set to give pressures in the range of 50-55 PSI.
Verify that the correct gases are being delivered to the correct ports on device before
initial use. This can be done closing O
2
gas cylinders, opening N
2
O gas cylinders,
and attempting to use flowmeter. Turn Total Flow Knob all the way open and
% N
2
O Knob all the way to 70%. There should be no gas flow. If either gas tube
shows flow, gas lines may be crossed internally. Turn off unit and call Accutron
before use.
