Safety Considerations
• Read this document for information on installation, handling,
mounting, general product specifications, and operation of this
product. These installation instructions contain important
information on handling the instrument.
• Working safety requires that all safety instructions and work
instructions are observed.
• Observe the relevant local accident prevention regulations and
general safety regulations for the range of use of the instrument.
• The installation instructions are part of the product and must
be kept in the immediate vicinity of the instrument and readily
accessible to skilled personnel at any time.
• Skilled personnel must have carefully read and understood the
installation instructions, before any work begins.
• The Bulletin 836P-N pressure transmitter measures and
monitors absolute and gauge pressures. The device has been
safely built with state-of-the-art technology and meets the
applicable requirements and EC directives. It can, however, be a
source of danger if used incorrectly or for anything other than
the designated use.
• Qualified individuals are required for installation and
commissioning. Failure to comply results in personal injury or
equipment damage.
• During mounting, make sure that the sealing faces at the
instrument and the measuring point are clean and undamaged.
• Safety Installation Considerations: Before installation,
commissioning, and operation, be sure that the appropriate
pressure transmitter has been selected in terms of measuring
range, design, and specific measuring conditions.

Commissioning
Making the Mechanical Connection
ATT EN TI ON : Before commissioning, the pressure transmitter must be subjected to a visual inspection.
• Fluid leakage is indicative of damage.
• Only use the pressure transmitter if it is in perfect condition concerning safety.
• While mounting, make sure that the sealing faces at the instrument and the measuring point are clean and undamaged.
• Only screw or unscrew the instrument via the spanner flats and to the prescribed torque with an appropriate tool. The correct torque
depends on the dimensions of the process connection and the gasket used (form/material). When screwing or unscrewing the pressure
transmitter, do not use the housing as contact surface.
• Be careful not to cross-thread.
• Max torque is 50 N·m (442.54 lb·in).

per EN 837 per DIN 3852-E
NPT
Parallel Thread Tapered Thread (NPT)
Correct sealing of the process connections with parallel threads at the sealing face must be made using suitable flat gaskets and sealing rings.
The sealing of the tapered threads (for example, NPT thread) is made by providing the thread with additional sealing material such as, PTFE tape
(EN 837-2).
Dismounting and Disposal
ATT EN TI ON : Residual media in the dismounted pressure transmitter can result in a risk to persons, the environment, and equipment. Take sufficient
precautionary measures.
Dismounting: Only disconnect the pressure transmitter once the system has been depressurized.
Disposal: Incorrect disposal can put the environment at risk.
Dispose of instrument and packaging materials in an environmentally compatible way and in accordance with the country-specific waste disposal
regulations.
Waste Electrical and Electronic Equipment (WEEE)
At the end of life, this equipment should be collected separately
from any unsorted municipal waste.
