3 The instller should hve generl knowledge of the instlltion techniques relting to Armflex tube nd sheet products. Use high qulity tools. A shrp knife, good brushes nd fresh Armflex dhesive, Arm-Chek Mstic nd Armflex Clener / Locl solvent re required. Use clen mteril. No dust, dirt, oil or wter should be present on the surfce. Clen using Armflex clener where necessry. Use correctly dimensioned mteril! Never pull glued joints when seling. When using pre covered Arm-Chek R tubes lwys push joints to gether nd fit under compression. On externl /internl instlltions lwys provide the Arm-Chek mstic sel to ll exposed sems nd joints fter the ppliction of the specified Armflex dhesive.

4 R APPLICATION MANUAL 1 Generl >> Working with Arm-Chek R Correct use of Armflex Adhesive Applying Armflex Adhesive Generl >> Working with Arm-Chek R Armflex Adhesive 520 Armflex Adhesive 520 hs been specilly developed to bond ll Armflex except HT/Armflex. Arm-Chek R nd ArmSound RD my lso be bonded using Armflex Adhesive 520. It joins the surfces relibly nd sfely t medium tempertures of up to +105ºC. The bond is resistnt to wethering nd ging. Armflex Adhesive HT625 Armflex Adhesive HT625 hs been specilly developed to bond HT/Armflex. Arm-Chek R nd ArmSound RD my lso be bonded using Armflex Adhesive HT625. When using HT/Armflex only Armflex Adhesive HT625 should be used. It joins the surfces relibly nd sfely t medium tempertures of up to +150ºC. The bond is resistnt to wethering nd ging. Prepring for work Check condition of Armflex Adhesive. Cns of Armflex Adhesive should hve been stored in cool environment wherever possible. Cns must lso hve been kept free from frost. Dmge due to frost cn be reversed by storing in wrm conditions, or for immedite use by plcing the cn into bucket of hot wter. Shelf life pprox. 1 yer. 1. Where instlltion surfces re soiled with dust, dirt, oil or wter ll of these contminnts must be removed nd, where pplicble, clened with Armflex clener before strting work. In ddition ll surfces to be joined must be dry before gluing begins. 2. Py close ttention to the instlltion instructions on the dhesive cn. Use smll cns during work so tht the dhesive does not thicken too quickly. Refill from lrger cns when necessry nd keep closed when not in use to void thickening. 3. Plnts must not be in opertion during the instlltion process! 4. Do not use dhesive under 0 C. If the dhesive is too cold it cn be wrmed in bucket of hot wter. At tempertures below 5 C, condenstion cn pper on the surfces to be glued or the dhesive film. If this occurs the mterils cn be glued only with difficulty. Check whether this hs hppened by pplying bsorbent pper. When working in res with high tmospheric humidity nd high tempertures see Hot Climtes dvice on or Armflex Appliction Mnul. 5. Stir dhesive well fter opening. If left to stnd, hevier components in the dhesive my settle in the bottom of the cn. These must be mixed thoroughly before use in order to effectively ctivte the dhesive. 1. Plnts must not be in opertion during the instlltion process! 2. Use brushes with short, stiff bristles. Alterntively the Armflex dhesive glue mster cn be used when working with the dhesive. A short pile fbric pint roller/lrge pintbrush my be preferred on lrge circulr nd flt surfce res. 3. Where ll over dhesive coverge is required pply dhesive in thin, uniform lyer to both the Armflex surfce nd the inner fce of the Arm-Chek R. Alwys ensure there is ll over dhesive coverge to both surfces with no signs of dry spots. 4. Allow the dhesive to tck-dry on overlpping detils. This tck time is dependent on number of fctors including the humidity of the ir. All overlpping contcting surfces shll be fully covered with Armflex Adhesive. 5. If surfces re left too long to dry they will not bond when pressure is pplied. When this hppens you cn re-ctivte by pplying further film of Armflex Adhesive. 6. Do not use dhesive under 0ºC (for further informtion see Armflex ppliction mnul pge 3). 7. Use Armflex clener to clen your tools, contminted metl surfces nd surfces which hve hd tlc pplied. Fingernil Test Test for tck-dryness by using the fingernil test : touch the surfce with fingernil, if the fingernil does not dhere to the surfce nd the surfce itself does not feel tcky the covering cn be positioned nd fixed using hnd pressure. Correct use Of Arm-Chek Mstics Arm-Chek mstic is n dhesive nd seling product designed to give dditionl nd long life protection to ll Arm-Chek R glued sems nd joints in externl environments. Arm-Chek mstic cn lso be used to vpour sel connecting metl prts ttched to piping equipment, within the service temperture limits of the product. Alwys use the pproprite Arm-Chek mstic for the colour of covering: Arm-Chek Grey mstic for use with Arm-Chek R Grey nd Arm-Chek Blck mstic for use with Arm-Chek R Blck.

19 4 Covering >> Ductwork, Irregulr Shpes, Vessels & Tnks APPLICATION MANUAL R Covering of insulted rectngulr shpes (ductwork, tnks nd flt surfces) To reduce lbour time it is recommend to instll the Arm-Chek coverings to the ductwork in single complete wrp-round : 1. Mesure the circumference of the ductwork nd cut the Arm-Chek coverings to the correct dimension, llow for 50 mm overlp of the fixing sem. Note: for lrger duct surfces step-by-step ppliction of the coverings in 2 or 4 seprte sections my be the preferred option where there is only one instller on the ppliction. 2. Apply the Armflex dhesive directly to both the Armflex nd the Arm-Chek R surfces in thin nd even mnner using lrge pint brush/ fbric pint roller. Allow the dhesive to touch dry. 3. Position the coverings nd fix to the Armflex sheet. Ensure the covering is in-line nd in the desired position. Apply firm even pressure nd smooth the covering round the surfce of the insultion voiding ny ir/ solvent pockets or crese s nd crinkles. Use plstic crd to enhnce the edges t the corners of the duct. Pinch nd smooth long the covering, s its being pplied. 4. Clen ll sem nd joints with Armflex Clener or loclly pproved solvent clener before pplying Ductwork bends nd irregulr shpes b 1. Mesure the length of the inner nd outer ductwork bend. Cut the Arm-Chek R covering to the correct dimensions, llowing n dditionl 50 mm overlp long ech edge for fethering. Note: Contour lines of duct nd other irregulr shpes cn lso be plotted by pplying chlk to the duct nd plcing piece of the covering directly onto the outline to crete n ccurte imprint (see section Hints ). 2. Cut the overlp into tssels using the fethering method. 3. Apply Armflex dhesive to one side of the Arm-Chek R pttern nd lso to the Armflex instlled on the duct. Allow to tck dry before pplying. 4. Apply the cut pieces following the procedures described (see chpter rectngulr shpes on this pge). 5. Smooth the covering using sptul to remove ny ir gps.
