1. IMPORTANT INFORMATION TO REVIEW PRIOR TO INSTALLATION, OPERATION
AND MAINTENANCE
Read the ENTIRE MANUAL prior to installing and maintaining the pressurization unit. Do not install or
perform maintenance on the pressurization unit if you do not understand all of the instructions. Contact
VoltAire at [phone] with any technical questions or concerns.
Warning: Improper installation and operation may cause property damage, personal injury or loss of
life. The pressurization unit shall only be installed and maintained by a qualified professional in strict
accordance with the requirements within this manual and in accordance with all local, state and federal codes.
In the event of a conflict, code requirements shall take precedence over the instructions provided within this
manual. The installer shall be aware of all code requirements and shall comply fully.
Use care when transporting and lifting the pressurization unit.
Remove power from the unit during maintenance and installation, as line voltage may be dangerous,
hazardous and lethal.
Warning: Wear proper personal protection equipment, including but not limited to safety glasses,
goggles and gloves. Edges may be sharp.
These instructions should be retained by the owner and/or with the unit.

3. PRODUCT DESCRIPTION
VoltAire Pressurization Systems provide the ability to apply positive or negative pressure to a building or room.
The system automatically maintains pressure relationships with adjacent areas or ambient air with a high
efficiency variable capacity fan. Fan speed is controlled through a specially programmed controller in order to
provide quick response times to changes in pressure by maintaining a pressure setpoint (measured in inches of
water column). The controller maintains all of the functionality of the Pressurization Unit maintaining the
differential pressure through adjustable PID loops and providing alarms. All alarms can be acknowledged on the
digital display that interacts directly with the controller. Air that passes through the unit is filtered with 1” pre-filter
and 2” final filter to ensure that clean air is being supplied. A low pressure alarm is provided via dry contacts
which notifies the user/operator of the need to change filters or to identify inadequate pressurization. The air
discharge grille exhausts downwards, but may be flipped so it exhausts upwards. The stainless steel cabinet
provides for durability and environmental resistance. The unit mounts to any wall that accepts the specified
cutout dimensions.

5. INSTALLATION INSTRUCTIONS
The mounting/cutout drawing reflects the minimum and maximum cutout dimensions for mounting the
pressurization unit to a wall.
Figure 4 –Wall Cutout
All Units are in Inches
Provide a rectangular hole in wall in accordance with Figure 4.
Clean the mounting surface to remove any residual debris and dust in order to ensure a proper seal when unit
is installed.

Install air intake hood (if applicable) with screen on unit and connect pressure sensor tubing to low side
pressure port.
Apply border of field supplied sealant around edges of cutout and around interior perimeter (the surface that
mounts against the wall) of the exterior mounting bracket. Install unit into wall using field supplied fasteners.
Note that all areas of the unit are maintainable either through the front opening or the duct opening, however all
standard maintenance is provided through the front of the unit. Reattach the three front panels and the four
hinges and secure them with their respective fasteners.
Figure 5
Install the field supplied disconnect adjacent to the unit and installer conduit and wire through electric entry
hole. Run high voltage wires in accordance with the electrical schematic through the electrical opening. The
installer shall provide electrical service and wire size in strict accordance with the National Electric Code and
any other applicable codes.
If external alarm notification is being used the installer may provide a second entry point into the electrical panel
and run low voltage wires for the alarm to the low voltage terminal block specified in the electrical schematic.
Dry contacts are rated at 8 amps at 240 VAC.
The unit is provided with fire smoke shutdown terminals F1 and F2. The unit is shipped with these terminals
jumped out. If the unit is to be connected to an external smoke/fire monitoring and control system these
terminals are to be used for a field supplied relay. Removal of this jumper will disengage the unit operation to
immediately eliminate airflow. Do not apply voltage to the F1 and F2 terminals.

6. START-UP AND CONTROLS INSTRUCTIONS
STOP AND READ BEFORE PROCEEDING! It is important to understand the controls and functionality of the
unit in order to achieve desired performance levels. The pressure controller is used to monitor differential
pressure across two environments to ensure consistent positive pressure in the room/building that is being
pressurized. The on-panel display can be used to adjust desired setpoints for the building’s differential pressure
in inches of water column.
The display has three main parts of its interface as seen in Figure 6.
FIGURE 6 –User Interface Overview
Display shown is default Pressure Controls
1) The screen displays the digital user interface.
2) The rotary dial allows you to scroll through the interface and select/input options. Scrolling through the
interface is achieved through rotating the dial clockwise or counterclockwise. Selecting/inputting options or
values is achieved through pressing on the rotary dial.
3) The return button returns you to the prior screen and can be used to cancel inputs and return to your prior
selection.

VoltAire Systems has a uniquely programmed password protected user interface for the Pressurization Unit as
shown in Figure 7 (shows lock screen). This interface is used to provide security over different functionality of
the pressurization unit. There are three main users that may be selected through the password screen. You can
enter password select mode by pressing the rotary dial on the lock screen. Doing so prompts you with a
password input as seen in Figure 8. Through password input. Default user and password information is found in
Table 1. Guest and Operator passwords may be changed by the installer. Admin is not available and is not
required.
