Handling instructions
All Viega ProPress components and associated
piping shall be free from dirt, debris or items that
may interfere with the sealing element and the
press connection.
Viega ProPress sealing elements, separator rings
and grip rings are to be visually inspected prior to
installation to ensure the seal is intact and properly
located within the fitting. See section 1.4.1 on page
6 for more information.
3.3
Pressing requirements
3.3.1 Minimum distance between fittings
To ensure a correct press, a minimum distance
between press fittings must be maintained (refer
to Table 3.1 and Table 3.2). Failure to provide this
distance may result in an improper seal.
Note:
Viega ProPress systems include XL (copper)
and XL (stainless) fittings. All XL sizes are 2½" to 4".
For installations where the minimum distance is 0, it
is particularly important to ensure the correct insertion
depth of the tubing into each fitting.

3.3.2 Pressing in tight quarters
The minimum distance between piping, or the piping
and the wall/ceiling construction, must be taken into
consideration in the planning phase for a problem-
free work process. The following figures illustrate the
clearance requirements for the jaws and fittings and
the procedure for pressing fittings in tight quarters.
