Aircom Installation

The AIRCOM system allows reducing installation, maintenance and system management costs. However, the installation shall be optimally executed by authorized, qualified and specialized personnel, accurately following the provided instructions to obtain the expected reliability, security and performance results. The lines shall always be slightly slanting towards a condensate collection and discharge point.In order to guarantee constant maintenance of the system or a general intervention, it is advisable not to install the system underground. Provide inspection wells in case of underground installation. 

Avoid conditions that may lead to excessive misalignment of the pipes. Lacking pipes alignment with the respective fittings may involve an incorrect position of the pipe end inside of the fitting and hence incorrect working conditions for the o-ring seal, and consequently possibile untightness situations.

Support the heavier accessories and equipment of a given weightmounte installed on the piping system (e.g. valves, flex some flexible hoses, flanged expansion compensators, filters etc.) using dedicated, suitable supports, to be installed arranged directly upstream and downstream of the same such accessories or equipment. If not properly supported, the static weight of such additional components or accessories may involve over the time negative consequences on the correct alignment of the piping-fitting connections and hence lead e.g. to untightness conditions. 

For same reason, direct hanging of heavier objects to parts of the piping, as e.g. hose reels or similar items hanging at droplegs, should be strictly avoided too. 

Provide good sealing of the threads using appropriate products in the proper quantity required. and at the right amounts. In case of doubts, we recommend to contact our Technical Service for suggestions about possible sealing solutions. 

For flanged connections it is recommended to always refer to our installation instructions and to make sure availability of a correctly trimmed torque wrench to ensure the proper tightening of the bolts (please be aware that flange-to-flange connections and flanged-fitting–to–flange connections require bolt tightening at different torque
values!). 

All supply system maintenance or modifications shall be carried out with the system empty. Always provide for the possibiity of disconnecting parts of the system that may be subject of maintenance, expansion or modifications thus avoiding total shutdown. 

Within the Quick Line System, various options are available to this purpose thus offering high flexibility in layout: “Sliding fittings” – similar to the usual straight fittings but without internal stop for the pipe (to be used in pairs, one sliding fitting at each end of the pipe section(s) that may require to be temporarily removed / disconnected); by proper operation they can be unscrewed and carefully slide onto the opposite pipe end, thus enablying easy removal from the side of the pipe section on which they were mounted. Reverse procedure to be followed for re-installation of the removed pipe section(s). Flanged fittings – on larger piping sizes, pairs of flanged fittings coupled together flange-to-flange on both ends of a pipe section enable easy removal from the side of such section of pipe, after careful unscrewing of the bolts connecting the flange pairs. Please take care of respecting proper assembly procedure for flanged fittings, when reassembling together the removed part of piping. 

Ball Valves and Butterfly Valves – such devices enable safe and reliable shut-off of branches of a piping network, to enable easy and safe disassembly of a part of it, so that their installation at “strategic” layout-specific places is also strongly recommended, e.g. upstream and downstream of a section or branch of piping subject to possible removal for maintenance/expansion/changes on the piping network.
