NSTALLATION TIPS

It is advisable to install your NAUTA® flexible tank in a small “berth” which will help to insure its protection against sharp objects. This berth prevents abnormal wearing from abrasion. Figure hose lengths with tank empty, and allow sufficient slack. Use grommets for positioning only, not for supporting a loaded tank. When securing, it is important to remember that tanks expand when loaded; a loose fit in the deflated state or elastic tie-downs will work best.

DDITIONAL FITTINGS

We have designed a comprehensive range of nylon fittings to be used only on NAUTA® tanks. Each type of fittings is composed of 3 parts which ensure together with the rubber seal and the rubber coated fabric a complete tightness. The necessary fitting for self-installation at the most suitable location on the tank wall. Generally, vent fittings are required on holding or gas tanks (not required on water), should be positioned at the higher end of the tank, while draw fittings are best located at the lower end. Under no condition should fittings be installed on the bottom side of the tank. All fittings should be installed on the bottom side of the tank. All fittings should be installed in the top half of the tank and not closer than 4” to the edge and not through a seam doubler.

AINTENANCE

NAUTA® flexible tanks used for drinking water will operate more satisfactory if the following procedures are observed. Before putting in use for the first time, partly fill the tank with warm water (50°c) and a 1% solution of mild detergent. After a few minutes, rinse with clear water and fill it again with water treated with chlorine tablets (follow package instructions for a 5% concentration). Empty after 2 hours and carefully and thoroughly rinse with clear water. These cleaning operations should be performed with the system fully installed so that all the piping undergoes the same treatment. When the tank will not be used for a long period (winter layup…), keep it partly filled with water and 10% of chlorine solution. Because it is not possible to completely evacuate the tank, this procedure best prevents the development of micro-organisms which could coat the inside and contribute to a bad taste in water. Before returning the tank to service, follow the same procedure as used with a new tank. Even if using your tank constantly, this cleaning operation is recommended at 6 months interval. Do not forget that the pipes also contribute to the water’s taste and should be involved in the regular cleaning process. 384, rue d’Alger – B.P 89 Tel : 33 (0)3 20 11 36 00 59052 ROUBAIX CEDEX Fax : 33 (0)3 20 11 36 71 Web : www.pennel.fr E- mail : nauta@pennel.fr
