1. Remove the cap and attach the supplied static-mixing nozzle to the cartridge and load the cartridge into the correct dispensing tool. Cut off the foil tube clip before use. For every working interruption longer than the recommended working time (Table 4) as well as for new cartridges, a new static-mixer shall be used.

2. Prior to dispensing into the anchor hole, squeeze out separately a minimum of three full strokes and discard non-uniformly mixed adhesive components until the mortar shows a consistent grey colour.

Installation in solid masonry (without sleeve)

3. Drill a hole into the base material to the size and embedment depth required by the selected anchor (Table 4).

4. Blow from the bottom of the bore hole two times. Brush the hole clean two times, and finally blow out the hole again two times.

5. Starting from the bottom or back of the cleaned anchor hole fill the hole up to approximately two-thirds with adhesive. Slowly withdraw the static mixing nozzle as the hole fills to avoid creating air pockets. Observe the gel-/ working times given in Table 5.

6. Push the threaded rod into the anchor hole while turning slightly to ensure positive distribution of the adhesive until the embedment depth is reached.

The anchor should be free of dirt, grease, oil or other foreign material.

7. Be sure that the anchor is fully seated at the bottom of the hole and that excess mortar is visible at the top of the hole. If these requirements are not maintained, the application has to be renewed.

8. Allow the adhesive to cure to the specified time prior to applying any load or torque. Do not move or load the anchor until it is fully cured (attend Table 5).

9. After full curing, the add-on part can be installed with the max. torque

(Table 4) by using a calibrated torque wrench.

Assembly instructions

1. Drill with hammer drill a hole into the base material to the size and embedment depth required by the selected anchor (Table 3).

2a.

Attention! Standing water in the bore hole must be removed before cleaning.

Starting from the bottom or back of the bore hole, blow the hole clean with compressed air or a hand pump (Annex 4) a minimum of four times. If the bore hole ground is not reached an extension shall be used.

or

The hand-pump can be used for anchor sizes up to bore hole diameter 20 mm. For bore holes larger then 20 mm or deeper 240 mm, compressed air (min. 6 bar) must be used.

2b. Check brush diameter (Table 2) and attach the brush to a drilling machine or a battery screwdriver. Brush the hole with an appropriate sized wire brush > db,min (Table 2) a minimum of four times. If the bore hole ground is not reached with the brush, a brush extension shall be used (Table 2).

or

2c. Finally blow the hole clean again with compressed air or a hand pump (Annex 4) a minimum of four times. If the bore hole ground is not reached an extension shall be used. The hand-pump can be used for anchor sizes up to bore hole diameter 20 mm. For bore holes larger then 20 mm or deeper 240 mm, compressed air (min. 6 bar) must be used. After cleaning, the bore hole has to be protected a gainst re-contamination in an appropriate way, until dispensing the mortar in the bore hole. If necessary, the cleaning repeated has to be directly before dis pensing the mortar. In-flowing water must not contaminate the bore hole again

3. Attach a supplied static-mixing nozzle to the cartridge and load the cartridge into the correct dispensing tool. Cut off the foil tube clip before use. For every working interruption longer than the recommended working time (Table 4) as well as for new cartridges, a new static-mixer shall be used.

4. Prior to inserting the anchor rod into the filled bore hole, the position of the embedment depth shall be marked on the anchor rods

5. Prior to dispensing into the anchor hole, squeeze out separately a minimum of three full strokes and discard non-uniformly mixed adhesive components until the mortar shows a consistent grey colour.

Assembly Instructions (continuation)

6. Starting from the bottom or back of the cleaned anchor hole fill the hole up to approximately two-thirds with adhesive. Slowly withdraw the static mixing nozzle as the hole fills to avoid creating air pockets. For embedment larger than 190 mm an extension nozzle shall be used. Observe the gel-/ working times given in Table 4.

7. Push the threaded rod or reinforcing bar into the anchor hole while turning slightly to ensure positive distribution of the adhesive until the embedment depth is reached.


8. Be sure that the anchor is fully seated at the bottom of the hole and that excess mortar is visible at the top of the hole. If these requirements are not maintained, the application has to be renewed.


10. After full curing, the add-on part can be installed with the max. torque (Table 3) by using a calibrated torque wrench.
