1. Cut stainless steel tubing only with an approved
stainless steel pipe cutting tool. Cut tubing at right
angle to permit proper joining with the fitting.
2. Keep end of tube a minimum of 4" away from the
contact area of the vise to prevent possible damage
to the tube in the press area.
3. Remove burrs from inside and outside of tubing to
prevent damage of the sealing element.
4. Check seal and grip ring for correct fit. Do not
use oils or lubricants. Use only Viega ProPress XL
(Stainless) sealing elements.
5. Mark proper insertion depth as indicated by Viega
ProPress XL (Stainless) insertion depth chart. Improper
insertion depth may result in an improper seal.
6. Illustration demonstrates proper fit of grip ring,
separation ring and sealing element.
7. While turning slightly, slide press fitting onto pipe to
the marked depth.
Note: End of tube must contact stop.
8. Press Viega ProPress XL (Stainless) fitting connections
with Viega ProPress XL-C rings and V2 ACTUATOR.
Note: Use of Viega ProPress XL rings and/
or Actuator (for Bronze Fittings) will result in an
improper connection. See Ridge Tool operator’s
manual for proper tool instructions.
9. Open XL-C Ring and place at right angles on the
fitting. XL-C Ring must be engaged on the fitting
bead. Check insertion depth.
10. With V2 ACTUATOR inserted in the tool, open
the V2 ACTUATOR as shown and connect the V2
ACTUATOR to the XL-C Ring.
11. Place the V2 ACTUATOR onto the XL-C Ring. Hold
the trigger until the Actuator has engaged the XL-C
Ring. Keep extremities and foreign objects away from
the XL-C Ring and V2 ACTUATOR during pressing
operation to prevent injury or incomplete press.
12. Release V2 ACTUATOR from XL-C Ring and then
remove the XL-C Ring from the fitting on completion
of press. Remove tag from fitting, indicating press
has been completed.
It is the responsibility of designers of
piping systems to verify the suitability of type 304 and 316
stainless steel pipe for use with the intended fluid media.
The fluid’s chemical composition, pH level, operation
temperature, chloride level, oxygen level, and flow rate
and their effect on AISI type 316 stainless steel must be
evaluated by the material specifier to confirm system
life will be adequate for the intended service. Failure to
do so may cause serious personal injury or property
damage.
Leak Testing with Smart Connect
®
:
Unpressed connections
are located by pressurizing the system with air or water.
When testing with water the proper pressure range is 15 psi
to 85 psi maximum. Leak testing with air can be dangerous
at high pressures. When testing with compressed air the
proper pressure range is ½ psi to 45 psi maximum. Following
a successful leak test, the system may be pressure tested up
to 200 psi with air, or up to 600 psi with water, if required by
local code requirements or project specifications.
