Installation Details – Drilling

Consult engineers drawings for hole dimensions; otherwise refer to ChemSet 801 Xtrem Technical Data Sheet

• Drill hole to specified dimensions using carbide tipped drill bit as appropriate.
• Ramset™ Dustless Drilling System is recommended as the fastest most certain method of removing drilling debris and dust and eliminates post-drilling hole cleaning.
• Otherwise drilling debris and dust must be removed by brushing and blowing out of drilled holes as described below.

Hole Cleaning – Carbide Drilled

Dust removal and cleaning is not required with Ramset™ D3™ Dustless Drilling System.

Drilling debris and dust must be removed from holes drilled with standard carbide as follows:

1. Using Ramset™ blower (Part Number HCPHV), compressed air blast or wet / dry vacuum (Ramset™ AC1630P), remove dust with 2 swift pumps.
2. Using the appropriate sized brush, with a twisting / rotating motion, insert brush to the bottom of the hole and remove 2 times.
3. Remove remaining dust residue with air blower (2 pumps), compressed air blast or wet / dry vacuum.

Hole Cleaning – Flooded Holes

 Remove dust and drilling debris from Flooded holes as follows:

1. Flush holes with clean running water until water is clear.
2. Using the appropriate sized brush, with a twisting / rotating motion, insert brush to the bottom of the hole and remove 2 times.
3. Flush holes with clean running water until water is clear.
4. Note a load reduction factor applies to Flooded holes but not to Wet Holes. Refer to RAmset Specifiers Anchoring Resource Book for Flooded Hole Reduction Factors

Opening and using Cartridge

1. Remove cap from cartridge and attach mixing nozzle Part Number ISNE

2. Load cartridge into dispensing gun (Ramset Part Numbers CUAP (Manual), CUAPN (Pneumatic) and CUAR18 (18V Battery Powered)

3. Dispense a small quantity of adhesive (1 to 2 trigger pulls) to waste to ensure both adhesive components are balanced

4. Insert mixing nozzle tip to bottom of hole (to avoid air bubbles) and inject adhesive. Gradually withdraw nozzle to keep the nozzle tip at the surface of the adhesive. Continue injecting until hole is about ¾ filled

5. Insert fixing using a twisting / rotating motion into adhesive and wipe away any excess

6. Allow adhesive to cure. Refer to Working and Loading Times table above

7. Apply torque (to threaded fixings) in 1 hour and apply full load after appropriate cure time
