Suitably rated conduit seals must be used for the conditions of use such as dust tight seals for
Class II & III, Groups E, F, G or water proof seals to prevent water ingress.
•
To maintain Type 4X and IP66 rating when installing threaded conduit, use PTFE thread sealant
tape according to instructions.

Installation
The PAX1 can be mounted in any position without affecting its operation. It can be mounted to a flat
surface using the mounting holes on the actuator. An optional mounting bracket is also available. For
details, see “PAX1 Exterior Dimensions”.
Clean all pipelines to remove dirt and scale before installation. Apply a minimum amount of pipe
compound to the male threads of the fitting only. Do not use Teflon tape as a sealant. Start with the
third thread back and work away from the end of the fitting to avoid the possibility of contaminating the
regulator. Install the regulator in the air line. The inlet and outlet connections are labeled on the
regulator body under the ports. Tighten connections securely.
NOTES: Oil free air must be applied to the regulator. Use a filter to remove dirt and entrained liquid in
the air line ahead of the pressure regulator. If an airline lubricator is used, it MUST be located
downstream of the pressure regulator or performance will be affected.
Installation below ground level
Pressure Regulator Vent: For units that are installed below ground and in areas where the unit may be
under water due to flooding, the pressure regulator vent should be piped to an area where the outlet of
the pipe is located at an elevation above any possible flooding. Water entering the bonnet vent will
cause an increase in the outlet pressure in direct relation to the depth of the water above the vent. This
can cause a significant increase in outlet pressure especially in low pressure systems and may cause
dangerous system overpressure conditions.
Conduit Seal: The PAX1 is rated for limited submerged operation but the user is responsible for ensuring
water cannot enter the PAX1 enclosure through the conduit connection and conduit port. Ensure the
conduit installation is water tight at elevations that may be submerged below water. Where conduit is
prone to collect internal condensation, appropriate conduit traps, drains and seals must be employed to
prevent condensation from collecting inside the PAX1 enclosure.
