Hanging the Omniguard
The Omniguard can be hung on a wall for easy viewing and to keep it
off of the floor, away from possible damage. Hanging the Omniguard
by the clip allows the cover to close, protecting the unit from water
damage while allowing the monitoring screen to be viewed through
the window on the cover. The pressure tubing and AC cord should exit
the case thru the foam slot, then the cover should be latched closed
to protect the unit from damage.
Caution: Only hang the Omniguard from a sturdy hook. A
fall could damage the unit and disrupt accurate pressure
measurements.
Loading the Thermal Printer Paper
Caution : Only use Omniguard thermal printer paper!
Thermal paper prints on one side only. If the paper roll
is installed incorrectly, the printer will be able to advance
the paper but will not be able to print on it.
1. Remove the paper lid and
thumbscrew. Cut the end of the
paper to a tapered point.
2. Place the paper roll, marked A,
into the paper lid so the paper
unrolls from the bottom.
3. Insert the tapered point of the
paper into the front panel slot
marked B, feed through the
printer until tapered point can be
pulled from the top of the front
panel at slot marked C.
Do not use the Paper Feed
function to advance the
paper.
4. From C, gently pull the paper until
the tapered portion is completely
exposed.
5. Replace the paper lid onto the
front panel and secure with the
thumbscrew.

Section 4: Detailed Operation
The Omniguard monitors and records (logs) the differential pressure
between the
nozzle and the nozzle (Reference).
In abatement applications, the Omniguard should be located outside
the containment area and not in any antechambers (i.e. shower or
changing room). This allows a supervisor or hygienist to monitor
pressure readings without entering the containment area.
Work Area Setup (see Appendix C for more details)
The Omniguard should be placed on a solid (non-vibrating) surface,
excessive vibrations disrupt accurate pressure measurement.
1. The intake end of the pressure tubing must be located a minimum
of 5 feet away from any openings or HEPA fan/filter units. Choose
a location away from excessive dust or moisture.
2. Cut a 1/2” slit in the polyethylene barrier and feed approximately
1 ft. of pressure tubing through it. Tape the tubing securely to the
polyethylene.
3. Connect the free end of the tubing securely over the
nozzle.
Be careful not to turn the nozzle.
4. Route the tubing and AC cord through the foam notch area on
the upper right corner of the case. Close the lid to protect the
Omniguard from damage, (be careful to not pinch the tubing or
AC cord).
5. The maximum hose length is limited to 70 ft (for 3/16”ID hose).
Lengths beyond 70 ft can degrade reading accuracy.
Caution: It is important that there be no kinks or
sharp bends in any part of the tubing. Any blockage
could inhibit accurate recording of the pressure in the
containment area.
Power-Up
To use the Omniguard, plug the power cord into a standard wall outlet
providing 115-230 VAC, 50-60 Hz and press the power
button.
The first time that a new Omniguard is turned on, the settings will be
at default values.
Initial Power-Up
Note: The first time the Omniguard is turned on, the
touchscreen will need to calibrated. The screen will
display a small box with an X in the middle of it. Touch
the X and continue until the calibration is completed.
Touchscreen calibration will need to be done if the
Omniguard is reset to factory default settings.
