GF CONTAIN-IT Plus 546 Pro Operating Instructions Manual page 13

Operating Instructions
1. Make a function test: close the ball valve by hand and open it again. Ball valves which do not function properly must not be in-
stalled.
2. Built the ball valve always into the system in the opened position.
3. Make sure that pressure rating, type of connection and dimensions correspond to the operating conditions.
4. Remove the ball valve from its original packaging immediately before installation.
5. Make sure the ball valve is in the «OPEN» position.
6. Join the inner pipe of the ball valve with the inner pipe of the double containment pipe system.
7. Adhere specific jointing instructions for solvent cementing, fusion and screw connection methods, see operating manuals of the
fusion machines or the cementing instructions of the adhesive manufacturer.
8. Join the connecting parts with the pipe ends according to their materials and types (fusion, cementing, screwing, flanges).
9. Abide by the waiting times after fusion or cementing as indicated in the chapter on "Jointing Technology" in the Planning Funda-
mentals Industry.
10. The tightening torque of the flange screws and other useful information, see GF Planning Fundamentals.
WARNING!
Material damage due to excessive tightening!
Material damage of the union nuts or the thread due to tools, such as pliers or if they are tightened too strong.
► Thighten the union nuts only handtight without the use of additional tools.
WARNING!
Material damage due to nonobservance of the insertion depth!
The pressure load of a damaged housing can cause breakage.
► When using the integrated fastening in the foot of the ball valve, always observe the requirements regarding the maximum in-
sertion depth of the screws.

CAUTION!
Forces due to thermal expansion!
In piping systems with temperature fluctuations, bending and longitudinal forces can occur if heat expansion is hindered.
In order as not to impair the functioning of the valve:
► Forces

Use mounting plate for front fastening. Forces which can occur during valve operation are absorbed (e.g. initial break-away
torque). The operating forces are thus prevented from being transferred over to the piping system.
