1 Anchor may be installed in a hole drilled with a carbide-tipped bit without cleaning the drilling dust from the hole . Temperature must be 41 ° F or higher .
Drilling dust must be removed from the hole if the temperature is below 41 ° F . See Manufacturer ’ s Published Installation Instructions ( MPII ). 2 When temperatures are below 41 ° F , TE-CD or TE-YD Hollow Drill Bits used with a Hilti vacuum cleaner are viable methods for removing drilling dust from the hole . 3 Holes drilled by diamond coring require cleaning with a water hose and compressed air . See MPII .
