INSTALLATION REQUIREMENTS & RECOMMENDATIONS:
Prior to the installation, please read through the requirements and recommendations listed below so you have
a clear understanding of your system and the location you plan to install the shut-off valve.
If you cannot meet these requirements, or are unsure of your system, please contact your dealer or PowerHalt
representative and we can work with you to overcome your installation constraints and challenges.
A PowerHalt Technical Representative can be reached Monday-Friday 6:00-4:30 (PST) at 800.663.0096
• A 1" clearance is required from the valve to any other components. The valve can be in any orientation.
• Maximum ambient air temperature at the valve should not exceed 120°C.
• All hoses, adapters, and fittings must be suitable for the vibration of the engine application, and of
reinforced type. *If unsure of your vibration requirement, contact Pacbrake.
• Flexible hose gaps should be kept to a minimum and the overall pipe quality and integrity from the shut-off
valve to the intake manifold should be confirmed.
NOTE: - Failure to ensure this may result in hose collapse during valve activation and
possible system leaks, preventing engine shutdown
- For excessive vibration applications, and installations with long pipe runs,
additional support brackets may be required.
• If an air intake flame trap is used, the valve must be installed upstream of the trap.
• Crankcase breather connections in the intake system between the valve and engine
(or in engine intake parts) must be sealed and replaced by an external breather.
• If you need to cut the existing intake piping to allow for the shut-off valve installation, please make sure to
cut the pipe off of the engine and that it is cleaned thoroughly to ensure no shavings are present.
NOTE: Failure to do so may result in engine damage caused by foreign debris ingesting into
the engine.
• It is highly recommended that the pipe is rolled with a bead to ensure hose fitting retention on both the inlet
and outlet sides of the shut-off valve.
• If more than one shut-off valve is installed on one engine it is imperative that the control method is
consistent with this requirement, ensuring valve activation is simultaneous for both valves.
