Flushing of pipesAll water systems, independent of their material, should be flushed thoroughly after their installation. The following requirements must be complied with before the installation can be put into service:
These requirements are met by
The flushing medium may be determined by local codes, engineering specifications or the needs of the mechanical equipment used. Where no requirements are established, potable water is sufficient for flushing aquatherm piping materials. GroundingMost building codes require that grounding be provided for all conductive components inside the structure. It is important to note that aquatherm pipes do not carry electrical currents and cannot be used to provide grounding. An alternative method of grounding is required. Where metal pipes are replaced by PP-R pipes, the ground can not be created by the piping system. An alternative ground system must be installed. The grounding system should be inspected by a qualified electrician. Transport and storageAquatherm greenpipe and climatherm pipes may be stored outside at any temperature. Providing a solid, flat, and level base for the pipe is very important to avoid a deformation of the pipes while in transport and storage. Improper storage of pipe can cause bowing. At temperatures below 0°C (32°F), it is possible to damage the pipes through strong impacts. In spite of its high impact resistance, the material must be treated with caution at low temperatures. UV-radiation has detrimental effects on all high polymer plastics. Maximum outdoor storage time is 6 months if removed from factory-supplied UV-protected bags. Outdoor installationIn applications where the installed pipe will be exposed to UV-radiation (such as outdoor applications), it is recommended that aquatherm greenpipe UV be used (Art.-No. 70758 – 70776). This pipe is engineered with an outer coating that protects the pipe from the aging and discoloration that can occur from prolonged exposure to UVradiation. See page 6.6. |
