Mounting instruction

  1. Determine the required component length.
  2. Shorten the VIROTEC®-drop nipple to the required length.
  3. Cut the outer thread and seal.
  4. Screw the VIROTEC®-drop nipple in the relevant fitting.
  5. Seal the sprinkler and screw into the inner thread (max. 25 Nm tightening torque).
  6. After fitting the sprinkler, visually inspect for cracks at the reducer.

 

 

Function

The VIROTEC®-drop nipple is made as a welded threaded pipe to DIN 2440. It is available in primed and zinced versions and in the standard lengths 0.5 and 1.0 m. The VIROTEC®-drop nipple is cut to the required length on building site and equipped with an outer thread. In the double-sided reduced pipe the cutting produces two drop nipples.

Telescope pipe VS
VIROTEC®-telescope pipe length tailor-made

The VIROTEC®-telescope pipe VS is an adjustable drop nipple for use in fixed, stationary water systems for extinguishing fires. It enables precise adjustment of the sprinkler heads to the location of a suspended ceiling in a vertical direction. The initial length can be adjusted to the installed situation by shortening the outer pipe. The longitudinal adjustment can take place after the pipe network has been completely installed. The installation time is considerably reduced

Mounting instruction

  1. Determine the installed length and if necessary shorten the tele pipe at the outer pipe (only VS 0.3 and VS 0.4 models). Important: Note the marking for the smallest length (160 mm).
  2. If necessary cut outer thread R1”.
  3. Seal the thread and fit the component. 4. Adjust length, adjustment made by screwing (also possible under pressure).
    Important: The adjusting pipe may only be screwed in up to the start of the outer pipe!


Function

The VIROTEC®-telescope pipe VS is made up of the following components:

Telescope pipe VSI

VIROTEC®-telescope pipe length tailor-made

The VIROTEC®-telescope pipe VSI is an adjustable drop nipple for use in fixed, stationary water systems for extinguishing fires. It enables precise adjustment of the sprinkler heads to the position of a suspended ceiling in a vertical direction. The initial length can be adjusted to the installed situation by lengthening the pre-fitted double nipple. The longitudinal adjustment can be carried out after the pipe network has been completely installed. The installation time is considerably reduced.

Mounting instruction

  1. Determine the installed length and if necessary lengthen the tele pipe with a 1” double nipple.
  2.  If necessary seal the extension and fit the component.
  3. Adjust length; adjust by screwing (even possible under pressure).
    Important: The adjusting pipe may only be screwed in up to the start of the connecting pipe!

Function

The VIROTEC®-telescope pipe VSI is made up of the following components:

  • Item 1 Outer pipe (CED-coated, black)
  • Item 2 Adjusting pipe (CED-coated, black)
  • Item 3 O-ring (silicon)

The VSI 0.1 and VSI 0.2 models are ready to install with a 1” inner thread. They have a double nipple for the extension. The length of the double nipple depends on the respective installed situation in the suspended ceiling and is freely selectable. It cannot be shortened by sawing. The precise lengthwise adjustment is achieved by screwing the adjusting pipe and outer pipe to gether. This is also possible under pressure. The seal seals off the gap between the two pipes.
