installation.
Analyzer Mounting
The 2-Pack and 3-Pack gas analyzers are manufactured for wall installa
-
tions. For detailed mounting dimensions → 3–1 and refer to the layout
diagrams provided with the purchased analyzer model.
Lifting/Carrying the analyzer system
Due to the analyzer’s size and weight (configurations can weigh approxi
-
mately 90 kg [200 lbs] for the 2-Pack and 130 kg [290 lbs] for the 3-Pack),
Hauser recommends the use of a forklift, pallet jack, etc. to lift or
move the analyzer. If the analyzer is to be lifted by hand, designate multiple
individuals and distribute the weight among personnel to avoid injury.
Before removing from the crate, move the analyzer as close as possible to the
final installation location. Never lift the analyzer by the electronics enclo
-
sures. Always carry the load using one of the following points/methods
(refer to the drawings included with the purchased analyzer system):
Hauser Class I Division 2 analyzers use a non-
incendive protection method, and as such all portions of the
local installation codes apply. The maximum allowed
inductance to resistance ratio (L/R ratio) for the field wiring
interface must be less than 25 µH/
Ω
. The maximum total
loop capacitance shall be 0.27 microfarads.
The safety of the analyzer is the responsibility of the installer
and the organization he/she represents.
Configurations requiring optional accessories (e.g., probe
assemblies) with specific characteristics must meet
manufacturer specifications.
Hauser analyzers are designed for operation within
the specified ambient temperature range. Intense sun
exposure in some areas may cause the analyzer temperature
to exceed the maximum.
When mounting the analyzer, be sure to position the
instrument so that it is not difficult to operate adjacent
devices. Allow one meter (three feet) of room in front of the
analyzer.
It is critical to mount the analyzer so that the supply and
return lines reach the supply and return connections on the
chassis, while still maintaining flexibility, so that the sample
lines are not under excessive stress.
