Tubing Installation; Confi Gurations - Pepperl+Fuchs 1001A Series Installation And Operation Manual

Model 1001A Installation and Operation Manual
HELPFUL HINTS
All work must be performed by technicians qualifi ed in
pneumatic tubing and electrical conduit installation.
Pepperl+Fuchs recommends the use of .035" wall
thickness, welded or seamless stainless steel tubing.
If fl exible tubing is used, it must be installed in a manner
that protects it from damage and corrosion.

System supply connections
1. Select or install a protective gas supply header tap, fi tted
with the proper tube size fi tting and located within twenty
(20) feet of the enclosure protection system.
2. If a service valve is placed between the protective gas
supply header and the enclosure protection system, it must
be installed in close proximity of the protected enclosure
and be labeled in accordance with section 2-11.4 of the
NFPA 496, 1998 edition.
3. Select the appropriate fi ttings required to connect the
protective gas supply to the protection system regulator
as determined on page 12, "Pneumatic Connection
Requirements".
4. Determine appropriate tubing route from the protective gas
supply header to the protection system regulator.
5. Bend tubing using industrial grade benders, check tubing
fi t to ensure proper seating between the tubing and fi ttings.
Fully ream all tubing ends.
6. Install tubing and tighten all fi ttings to fi tting manufacturer's
specifi cations. Secure tubing to appropriate structural
supports as required.
Enclosure supply & reference connections
For systems supplied with an ECK (enclosure connection kit),
go to page 15 "Electrical Supply Requirements".
1. Choose location for the enclosure supply connection(s)
based on the requirements on page 6, "Getting Started".
2. Place the enclosure reference connection fi tting directly
behind the enclosure protection system whenever possible.
For systems protecting multiple enclosures in series, the
enclosure reference connection fi tting must be placed
on the last enclosure in the series. See page 6, "Getting
Started."
3. Drill and deburr enclosure supply and reference fi tting holes
on the protected enclosure. Mount the fi ttings.
4. Determine appropriate route for the enclosure supply and
reference tubing.
5. Bend tubing using industrial grade benders, check tubing
fi t to ensure proper seating between the tubing and fi ttings.
Fully ream all tubing ends.
6. Install tubing and tighten all fi ttings to fi tting manufacturer's
specifi cations. Secure tubing to appropriate structural
supports as required.

Tubing Installation

Tubing PM Confi gurations
Enclosure Bulkhead Fittings
1. Select the fi ttings required to install the system supply,
system supply bulkhead Fitting and atmospheric reference
bulkhead fi tting. See page 12, "Pneumatic Tubing
Requirements."
2. Choose location for the system supply bulkhead fi tting. This
fi tting allows the protective gas supply to pass through the
wall of a protected enclosure to the protection system's
regulator supply inlet connection.
3. Choose location for the atmospheric reference bulkhead
fi tting. This fi tting allows the enclosure pressure gauge to
reference atmospheric pressure.
4. Drill and deburr system supply and reference bulkhead
fi tting holes in the protected enclosure. Mount the fi ttings.

4. Determine appropriate tubing route from the system supply
bulkhead fi tting to the protection system regulator.
5. Determine appropriate tubing route from the atmospheric
reference bulkhead fi tting to the enclosure pressure gauge's
reference inlet connection.
6. Bend tubing using industrial grade benders, check tubing
fi t to ensure proper seating between the tubing and fi ttings.
Fully ream all tubing ends.
7. Install tubing and tighten all fi ttings to fi tting manufacturer's
specifi cations. Secure tubing as required.
