It should take some effort to attach the nozzle to the mounting frame on the respective device. If the nozzle is too loose, it can be bent with a suitable pipe wrench or similar. (cf. Instruction Manual). If the disk reflector is not positioned exactly at an angle of 90° to the base body, this is due to the manufacturing process, does not affect the function and is therefore not a reason for complaint.

Instruction Manual 

Instructions Manual for The Disk Reflector Nozzle (SRD)

The SRD (nozzle) can only be used in conjunction with a hot air tool (for 31.5- or 33.5-mm mounting frames, depending on the version)

For this purpose, the nozzle is placed on the hot air tool. Make sure that the nozzle is tight enough with tension so that it can only be pulled off with a little force. More frequent use may cause the mounting frame to widen. In this case, the mounting frame must be compressed slightly with a pipe wrench or similar until the nozzle sits tightly on the hot air tool again. The nozzle is made of A2 stainless steel.

The nozzle is designed for loosening glued joints by uniform heating of the inner side of a pipe section/remnant (D 50 – 75) glued in a sleeve (PVC fitting, PVC insert or similar).

When the pipe section is soft enough, a screwdriver (3-5 mm blade width) can be used to pierce between the sleeve and the pipe. The pipe section can then be bent inwards. Make sure that you push the screwdriver through to the end of the pipe section.

With the help of a short but strong needle-nose pliers or similar, you can grab the pipe section and loosen it gradually by rotating it.

The key is to heat the pipe section as quickly but safely as possible so that the outer sleeve remains as cold as possible to prevent deformation, and little heat passes through the fitting or similar.

When used correctly according to the above instructions, the sleeve can be glued again immediately. It may be necessary to remove any protruding glue residues and to clean the sleeve with solvent.

After use, the nozzle must cool down before being removed from the hot air tool.

Observe the instruction manual and the safety notes of the hot air tool used.

Wear gloves to avoid injuries due to heat or cuts.

Nozzles that can no longer be used must be disposed of as scrap metal.
