Any rotation of the inlet or outlet fitting during installation of a metal
seal device may result in a leak. Always use two (2) wrenches when
attaching gas lines to prevent rotation.
WARNING !
Prior to installation:
a. Verify that tube fittings match the fitting type and size supplied with
your Quantim instrument.
b. Make certain that all piping and fittings are clean and free of
obstructions for the instrument and filter.
c. Assure that the final installation permits easy access to the
instrument.
2-7 Mechanical Installation
(For Dimensional Drawings see Section 1-4 Dimensions)
Recommended installation procedures:
a. All models should be mounted to a stable surface that is relatively free
from mechanical shocks and mechanical vibration using the supplied
mounting plate.
b. Leave sufficient room for access to the electrical connections.
c. Install in a manner that allows the instrument to be easily removed.
d. Install the instrument with an appropriate filter on the fluid inlet side.
e. It is recommended that a positive shutoff valve be installed downstream
of the Quantim product to allow for proper zeroing after installation.
Manifold Mounting
If the Quantim is provided with the downport option it should be mounted to
the proper manifold. Make sure the correct seals are used between the
Quantim and the manifold to prevent leaks.
