Attach the unit to its mounting surface with the four self-tapping #10x3/4” sheet
metal screws through the holes in the mounting feet. The preferred mounting
orientation is with the pressure ports facing down to prevent condensation
from entering the pressure transducer. Do not mount to a vibrating surface
as vibration may cause issues with the accuracy of the sensing element. See
page 3 for an actual size mounting template for the unit.
The two cover latch screws must be installed to achieve an IP66 rating.
After Auto-Zeroing, remove the deadhead tubing and push the system tubing
onto the port nipple without creating any kinks or holes.
If a hole must be cut into the plastic plugs in the ½” NPSM
threaded ports of the BAPI-Box enclosure, it’s recommended
to use BAPI’s Clean-Cut Tool. Not using this tool could cause
damage to the electronics of the sensor. See the Accessories
section of BAPI’s website or product catalog for more info on
the Clean-Cut Tool.
