Friatec Electrofusion Assembly Instructions

WARNINGFRIALEN ® Safety Fittings with integrated heating coils guarantee optimalheat transfer through their exposed heating coils and may thus notbe scraped at the inside of the fitting.4.3 External and internal chamfering of the cutting edgeFor this purpose, the manual scraper is a suitable tool. Remove swarvesfrom within the pipe.4.4 Restoration of irregular /oval pipesPipes, in particular bundled coils anddrums, may loose their roundnessduring storage. If the pipe out-of-roundnessin the fusion zone area exceeds1.5% of d (outer diameter) oris > 3.0 mm, these pipes must be roundedin the fusion zone area. Pleaseuse rounding clamps for this purposewhich are installed at the endof the fusion zone (see Fig. 6).4.5 CleaningThe surfaces of the pipes to be fusedand the interior surfaces of theFRIALEN ® Safety Fittings must beabsolutely clean, dry and free fromany grease. These areas are to becleaned with a suitable cleaningagent and exclusively with absorbent,lint-free and non-dyed paperdirectly before the assembly and afterscraping (see Fig. 7).Fig. 6Fig. 7We recommend PE cleaning agents which meet the requirements of the testbasis DVGW-VP 603, e.g. AHK cleaning agents.When cleaning, ensure that no contaminations from the unscraped pipesurface are introduced into the fusion zone.9
