Injection method for drill hole depth ≤ 250 mm (without overhead applications)
Injection method for drill hole depth > 250 mm or overhead applications
required mortar level
Injection system Hilti HIT-HY 150 MAX
Product description
Installation instruction
Inject adhesive from the back of the drill hole without forming air voids.
Inject the adhesive starting at the back of the hole, slowly withdrawing the mixer
with each trigger pull.
Fill approximately 2/3 of the drill hole to ensure that the annular gap between the
anchor and the concrete is completely filled with adhesive along the embedment
length.
After injection is completed, depressurize the dispenser by pressing the release
trigger. This will prevent further adhesive discharge from the mixer.
Assemble mixing nozzle HIT-RE-M, extension(s) and piston plug HIT-SZ
(see Table B5 or B6).
For combinations of several injection extensions use coupler HIT-VL-K.
A substitution of the injection extension for a plastic hose or a combination of
both is permitted.
The combination of HIT-SZ piston plug with HIT-VL 16 pipe and then
HIT-VL 16 tube support proper injection.

For overhead installation the injection is only possible with the aid of extensions
and piston plugs. Assemble HIT-RE-M mixer, extension(s) and appropriately
sized piston plug (see Table B5 or B6). Insert piston plug to back of the hole and
inject adhesive. During injection the piston plug will be naturally extruded out of
the drill hole by the adhesive pressure.
After injection is completed, depressurize the dispenser by pressing the release
trigger. This will prevent further adhesive discharge from the mixer.
