1.0 Introduction
The Setra LITE Construction Kit provides everything needed to monitor pressurized spaces
around on-site construction or fume-extraction. The kit can also be used to verify pressurized
isolation of temporary spaces such as renovations, loss of power conditions, and temporary
isolation rooms. Simply place the kit outside the work area and run the flexible tubing inside the
pressurized space to provide continuous differential pressure readings and visual alarming.
The visual indication on the kit is provided via the Setra LITE pressure monitor. The Setra LITE
features an LED light ring that will glow red if room pressurization violates the congured alarm
threshold. The design of the light ring allows the room status to be visible from a distance,
even from down a hallway. With a simple press of the front lens of the unit, the LCD displays
the reading of the current differential pressure. Conguration of the unit can be performed on
the device via buttons located behind the removable front lens. The unit can be put into and
taken out of “Standby” mode by pressing the front lens 3 times in quick succession.
2.0 Key Features
2.1 Case
The Setra LITE Construction Kit comes in a convenient easy to carry case which is designed
for the most rugged applications but still compact enough to provide pressure monitoring in
a minimally invasive footprint (12” x 15” x 7”). The case is IP67 (NEMA 6) rated and includes
auto venting for air travel. The lockable case is also padlock-ready for added security while
travelling or while on site.
Conveniently located on the outer side of the case are all the connections needed for power,
pressure sensing, and signal wiring. As shown in the image below, the AC power jack
(provided) plugs into the side or the toggle button can be used to operate on battery power
(provided) instead. The 2-wire output signal is available to connect to from the side of the case
to run an analog output to a local BAS or monitoring system for advanced visualization and
data logging of the pressure readings. The pressure tubing (provided) connects to the quick
disconnect tubing port on the side to be run into the pressurized space being monitored.

3.0 Unit set up
3.1 Power
Remove pluggable AC power pack from the case and snap on the plug adapter needed for
your location (USA/UK/EU/Canada/Mexico/Asia). The adapters can be switched out with the
quick release button on the power pack as seen in Image 1.
Connect the adapter to the outer side of the case via the power jack as shown in Image 2.
Turn on via the Power Switch located as shown in Image 2. The power switch functions as
follows:
Center = OFF
Up = ON via AC Power (up direction is towards case handle)
Down = ON via Battery Power
If power is lost or unavailable, simply move Power Switch to downward position. The battery
pack will begin to power the unit and last 10 – 12 hrs. Replacement batteries are any standard
retail 9V batteries (qty 4).

3.2 Pressure Sensing Tubing
Remove the pressure sensing tubing from the case. One end of the tubing has the sintered
lter to be placed inside the pressurized space and the other end has the connection for the
Quick Disconnect Tubing Port. Connect to the Quick Disconnect Tubing Power as shown in
Image 1.
Note: Unit should be placed in such a manner as to reach the sensing space within 15 feet.
Tubing can be routed over or under isolation tarp as needed and secured in the space such
that the sintered lter, seen in Image 2, is present in the space. The pressure in the space will
be compared to the pressure where the eld case is located.

3.3 Monitor Interface
With power connected, silicon tubing in place and power switch in the upward position,
the unit will begin sensing the differential pressure between the case environment and the
isolation area immediately. In order to set up the visual green / red alarming and set up the
desired monitoring features proceed with the following steps:
3.4 Removal
With the unit powered on, grab the lens by the left and right edge, then pull away from the unit.
Locate the 3 buttons located below the LCD display.
Press and hold the LEFT button for 3 seconds to access the conguration menu (the LED ring
should shut off after the conguration menus are accessed).
Press the RIGHT button (“”) to navigate to the next screen.
Press the LEFT button (“”) to navigate to the previous screen and eventually exit the
configuration menu. The unit will also automatically timeout and return to normal operation if
no buttons are pressed for a set period of time.
To change a setting, navigate to the desired setting screen, and press and hold the RIGHT
button(“”). The screen text should flash 3 times, indicating ability adjust the setting.
Use the LEFT (“”) and MIDDLE (“") buttons to adjust the selected setting.
When finished, press the RIGHT button ("”) to save the setting. The screen text should flash
3 times to indicate return to the main configuration selection screens.
To exit configuration, press the LEFT button (“”) to navigate to the previous screen and
eventually exit the configuration menu. The unit will also automatically timeout and return to
normal operation if no buttons are pressed for a set period of time.

3.5 Conguration menus
This section will describe the function of each of the conguration menus.
3.5.1 Zero
3.5.2 Alarm limits
Press and hold the RIGHT button (“”) to zero the onboard pressure sensor. The unit contains
an onboard valve to automatically equalize the pressure differential across the sensor.
Press and hold the RIGHT button (“”) to adjust the alarm limits (i.e. pressure at which the
LED ring will turn red); the screen text will flash 3 times to indicate that the setting is ready to
be adjusted.
Use the LEFT ("") and MIDDLE ("") buttons to adjust.
When finished, press the RIGHT button (“”) to save the setting. The screen text should flash
3 times to indicate return to the main configuration selection screens.
