07 System protection
7.1
General
• Prior to any installation, ensure all components
being used are REHAU EDGE
TM
components only
•
Do not use dirty or damaged system components, pipes,
fittings, compression sleeves or seals.
• Make sure that the connection components are free
of inadmissible stress during assembly and when
in operation. Make sure that the piping has suicient
scope of movement (e.g. from deflection legs).
• Protect the system against damage (e.g during
the construction phase and when installed in areas
with vehicles and machines)
Installation temperature
• Minimum installation temperature is -5ºC
• Maximum installation temperature is +50ºC
7.2
Protection against corrosion and damage
• Screed, cement, mortar, plaster, bonding agents
and other materials and substances may
cause corrosion. Where a contact with such
substances is foreseeable, protect fittings
and compression sleeves from contact, e.g
by wrapping with RAUTITAN protective
tape, silicone tape or another suitable tape.
Petrolatum tapes, or tapes containing solvents
are NOT suitable.
• Do not install pipes and fittings, pipes
and compression sleeves in wet areas
(e.g. green houses, indoor pools, or conditions
where water or condensation on the surfaces
must be expected on a regular basis)

-2 Avoid contact with solvents and oils including paints,
lacquer, liquid thread sealant and tapping oil.
EDGE
TM
polymer fittings
• EDGE
TM
polymer fittings are solvent resistant and
have excellent resistance against most aliphatic and
aromatic hydrocarbons and Chlorine.
Solvent resistant means that EDGE
TM
polymer fittings
are not susceptible to environmental stress cracking
when in contact with solvents found in glues,
primers and thread sealants commonly used on building
sites. Only use leak detection agents (e.g. foaming
agents), sealants, thread sealants, cleaning agents,
building foams, insulation, protective tape, adhesive
tape and flux, which were approved by the respective
manufacturer for PVDF.
• When using the connection components, check the
compatibility of materials for the corresponding area
of application.
• Contact with basic environments with pH≥12 is
not permitted.
