The holders for the water trough must be placed horizontally at even intervals of max. 75 cm, and in the horizontal
alignment. For further distances, see the illustration below. Recommended tools for installation are a chalk cord
and a cordless drill.
3.6.4 Glue connections
LUBING recommends “Tangit” glue for glue connections.
3.6.4.1 Preparation of the parts
The pipe ends must be cut off rectangular, chamfered and deburred to 15°. Missing
or improper pipe chamfers will prevent permanently tight connections.
3.6.4.2 Pre-treatment of the adhesive surfaces
Clean the adhesive surfaces (pipe end and water trough outside, fittings and couplings inside) of gross dirt first.
Remove any adhering ice by heating (hand-warm). Then the adhesion length of the fitting must be marked on the
pipe end so that the required glue application and complete insertion of the pipe can be reviewed. Fine cleaning
takes place with Tangit cleaner. For this, a white, lint-free roll-crepe paper is soaked with cleaner and used to clean
the surfaces to be bonded thoroughly to make them grease- and dirt-free. The paper must be replaced after each
cleaning process. The surfaces cleaned with Tangit cleaner must be dried before application of glue.
3.6.4.3 Processing
Stir Tangit well before use. The glue should flow off slowly from a rod held diagonally and form a kind of glue vane.
Apply an even, uninterrupted glue layer inside the sleeve and then on the pipe in the axial direction. Thinly coat the
inside of the sleeve with Tangit in order to avoid detrimental bead formation in the pipe; apply it thickly to the pipe
end. Tangit PVC-U can be used to bridge tolerances up to +0.6 mm according to DIN EN 14814.
Push together the pipe ad sleeve to the stop or to the full sleeve depth at once without twisting/canting against
each other and hold them in this position for a few seconds until the glue has cured.
Remove excessive glue with the cleaning paper directly after joining. Due to the quick curing of the glue, the joined
parts must be pushed together within 4 minutes after application of the glue commences.
The open time of Tangit, i.e. the time from starting to apply glue to joining of the parts, depends on the film
thickness of the glue and/or the ambiance temperature.
At a film thickness of 1 mm, the processor will have the following times depending on the processing temperature:
3.6.4.4 Waiting times/pressure test
The pipes must not be moved during the first five minutes after bonding. For temperatures below +10 °C, this time
will increase to at least 15 minutes.
The lines should only be filled and pressure tests up to a test pressure of 1.5 x PN should only be performed 24
hours after the last bonding. It is recommended to flush lines that are not taken into operation at once well and to
