Insert foil pack in foil pack holder. Attention!
Check foil packs and foil pack holder for proper functioning
or damage - especially after they have been dropped. Dropping foil packs, also foil packs already inserted
into the foil pack holder, is likely to cause damage leading to mal function. Never use damaged foil packs
and/or damaged or unclean foil pack holders.
6
Tightly attach Hilti HIT-RE-M mixer to foil pack manifold.
Attach new mixer prior to dispensing a new foil
pack (snug fit). Do not modify the mixer in any way. Make sure the mixing element is in the mixer. Use
only the type of mixer supplied with the adhesive.
7
Insert foil pack holder with foil pack into HIT-dispenser P 8000 D.
8
Discard initial adhesive.
The foil pack opens automatically as dispensing is initiated. The mortar initially
dispensed from the mixer must not be used for making fastenings and has to be discarded. Do this by
pulling the empty outer packaging over the mixer and holding it there to prevent mortar squirting out. Dis-
pense a quantity of approx. 65 ml (quantity corresponds to a cylindrical shape of approx. 50 mm diameter
and height of 35 mm) into the bag and dispose of this. The foilpack opens automatically as dispensing is
initiated. If a new mixer is installed onto a previously-opened foil pack, the first trigger pulls must also be
discarded as described above. For each new foil pack a new mixer must be used.
Caution!
Never remove the mixer while the foil pack system is under pressure.

Inject adhesive from the back of the borehole without forming air voids:
Verify if borehole conditions have changed (e.g. water in the borehole) after cleaning. If yes, repeat cleaning
according points 2 - 4.
•
Inject
the adhesive starting at the back of the borehole (use the extension for deep boreholes), press
the dispenser trigger in variable speed regulation mode and slowly withdraw the mixer as mortar is
dispensed.Fill holes approximately 2/3 full, or as required to ensure that the annular gap between the
fastening element and the concrete is completely filled with adhesive along the embedment length.
•
Piston plug injection - is recommended for borehole depth > 250 mm. For overhead installation the
injection is only possible with aid of piston plugs Hilti HIT-SZ.
Assemble HIT-RE-M mixer, extension(s) and appropriately sized piston plug HIT-SZ. Insert piston plug to
back of the borehole and inject adhesive as described in the injection method above. During injection the
piston plug will be naturally extruded out of the borehole by the adhesive pressure.
10
Insert fastening element into borehole.
Mark and set fastening element to the required embedment depth
“h ef”
. Before use, verify that the fastening element is dry and free of oil and other contaminants. To ease
installation, the fastening element may be slowly twisted as they are inserted. After installing a fastening
element, the annular gap must be completely filled with adhesive.
Attention!
For overhead applications take special care when inserting the fastening element. Excess ad-
hesive will be forced out of the borehole - take appropriate steps to prevent it from falling onto the installer.
Position the fastening element and secure it from moving/falling during the curing time (e.
g. wedges).
Observe the gel time
“t gel”
, which varies according to temperature of base material. Minor adjustments
to the fastening element position may be performed during the gel time. See table.
11
Do not disturb the fastening element
once the gel time
“t gel”
has elapsed until
“t cure,ini”
has passed.
