WARNING:
Use high–flow cartridge for flows 5-40 lpm and low-flow cartridge for flows 1-8 lpm.
7-7. Plug in power cord, and check that all the display indicators light. The Precision Flow
®
performs a self-test:
• all icons and numeric displays light up for a few seconds
• internal sensors and control systems are checked
• if no faults are detected the unit enters STANDBY mode
• “Water Out” icon indicates there is no water in the disposable water path
• status LED is amber
7-8. The Precision Flow
®
unit has three controls.
Run/Standby Button
– Powers the unit on and places it in standby.
Setting Control Knob
- Allows you to adjust the parameters.
Alarm Mute Button
– Will intermittently silence alarms
and also dims the display panel.
The Precision Flow
®
has three modes. Those are
Sleep
,
Standby
, and
Run
. In Sleep mode, the unit will have a
blank screen and an amber light showing.
The unit
cannot be started from sleep.
To put the unit in
Standby
, simply rotate the blue
Control Setting Knob to illuminate the display. You
will see the three parameters of Flow, percent
oxygen, and Temperature. There will also be a
corresponding vapor transfer cartridge indicator
on the lower right hand side which will identify
what type of disposable patient circuit is
in place (Blue/High or Red/Low).
To enter
Run Mode
, with the screen illuminated,
simply press and release the Run/Standby Button.
The machine will give a series of 10 beeps, and begin to power up. At this point the small
light above the Run/Standby Button will change from Amber to flashing Green. During this
start up, you will also see two amber alarm indicators illuminated. This is normal and is
part of the Precision Flow
®
start up self test.
7-9. Push or rotate the control setting knob in either direction to light up the display in
STANDBY mode.
7-10. Press the Mute button to change between bright and dim display (this function is only
available if no alarms are active).
7-11. To connect the sterile water supply, remove spike cap and disinfect spike with 70-90%
isopropyl alcohol or equivalent. Firmly insert spike into spike port of the sterile water supply,
avoiding direct hand contact. Unclamp the water inlet tube so that water (>200 ml) flows into
the disposable water path and the “Water Out” alarm icon clears. Wait approximately 90
seconds (or 180 seconds if using a hard water bottle) before pressing the Run/Standby button.
7-12. Press Run/Standby button to start gas flow, pump and heater.
Press twice if the display is initially blank.
