Carlon Duct Proofing and Cable - Manual

DUCT PROOFING AND CABLE INSTALLATION
www.carlonsales.com
Duct Proofing for Cable Pulling
Use 175 or 250 CFM Compressor for maximum line blowing potential. Choose
pull line based on length of pull and tension expected.
1. Remove all plugs in terminator at exit end and only the plug being shot
into on the entrance end.
2. Turn threaded nozzle into terminator until tight, without pull line or missiles
to blow any debris or water which might have collected.
3. Open gate on nozzle to apply air to innerduct. Close gate after any debris
or water has been blown out.
4. Unscrew nozzle and thread pull line through eyelet in nozzle and tie to line
blowing missile. Place pull line reel on stand for feeding.
5. Place line blowing missile into open innerduct and carefully open gate on
nozzle.
6. Feed pull line off reel and keep slight tension to avoid rope packing in
innerduct.
7. When using flat tape as pull line, use twisted blow line (RP142) to blow in
and retrieve flat tape.
Proofing for Jetting Cable
Use 375 CFM compressor for best results
1. Attach polyethylene feed tube (1'' SDR 13.5 for 4 way and 1 3/4'' SDR
13.5 for 3 way) with coupling recommended for high speed air blowing
systems to empty innerduct extension on jet through terminator.
2. Assemble coupling according to high speed blowing system
manufacturers recommended instructions.
3. Attach opposite end of polyethylene feed to high speed air speed
machine.
4. Plug all unused holes in the Multi-Gard terminator at entry point and
remove all plugs at exit terminator. Apply 100 -110 PSI to the Multi-Gard
innerduct. Close the air output valve and stop compressor. The innerduct
is acceptable if a loss of 20 PSI or less happens within 2 minutes of
pressurization. WARNING: NO PERSONNEL IN MANHOLES DURING
PRESSURE TEST.
