1. Do not perform continuous pressing in order
not to overheat the press or the grippers. Every
40/50 pressing let the presser stand for 15
minutes (refer in detail to what is contained
in the manual of the pressing machine).
2. Do not re-use fittings that have already been
clamped.
3. Do not tamper with the tools.
4. Check the tools regularly for correct opera-
tion.
5. Carefully read the Instruction Manual sup-
plied with the pressing tool.
6. Keep pressing machine and jaws always
clean.
7. In the event of pressing joints with threaded
connections (e.g.: flanged elbows with female
threading), use the provided grip-wrench
during tightening, to avoid deformations and
tensions.
8. In the under wall systems, to avoid corrosions
and stress corrosions phenomena (happen-
ing in the presence of humidity, chlorides,
ammonia vapours, highly reactive hydraulic
binders, etc) it’s recommended to provide
the joints insulation by the means of proper
materials (insulating tape/band, etc).
9. For the heating and water/plumbing systems
you must arrange to have the appropriate
safetydevices installed (expansion tank ,
safety valve ) to avoid pressure levels from
rising above the maximum values established
for multi-layer systems or hammering.
Freezing of the fluid being conveyed must
also be avoided.
Such phenomena can in fact cause damage
or the breakage of parts (pipes, joints,
accessories, etc.).
Attention!
Do not effect couplings with tapered or
uncalibrated cast-iron threads, because the
high closing torque would damage the female
brass couplings.
Teflon may be used to provide the seal. Hemp,
too, may be used as long as the quantity is
correct.
