You MUST use a purge gun toremove all air from the system if any divider block system components,(tubing or connections, divider blocks, lube pumps, check valves etc. ) aredisconnected, or removed. Although divider block systems can sometimesself purge of air, this severely delays lubrication reaching cylinders and rodpacking. Allowing air to remain in the system can result in phantom no-flowshutdowns and premature failure of rings, rods and packing. If only 12inches of the tubing lines are filled with air, lube oil can take up to 30 minutesto reach lube points. Therefore the operator MUST use a purge gun toremove air from the system before startup or after maintenance. This willensure that all air trapped in the divider block system is completelyremoved and cylinders and packing will immediately receive neededlubrication when the compressor is started.Use only clean filtered oil common to the system! CAUTION when purging the divider block lubrication system.Discharge Sideof Lube PumpTubingPurging AirFrom Divider BlockLubrication SystemsFollow this procedure after installing any divider block system, replacing tubing, replacing individual dividerblocks or when any components of the divider block system are removed or replaced.Step 1: After maintenance or before compressor start-up, loosenthe tubing connections at the inlet of the master divider valve,cylinder and packing gland injection points. If there are secondarydivider valves loosen tubing connections at the inlet of thesecondary divider valves .Step 2: If a purge port is available at the pump head connect thepurge gun. If no purge port is available remove the tubing from thedischarge side of the pump and connect the purge gun to the tubing.Visit Us On the Internet: www. cct.nuCC TechnologyDivider Block SystemPurge Gun10005001500Part # 382510-32000CC TPurge GunPump inVertical Position25003000Purge PortStep 3: Pump clean oil common to the system into the tubing lineuntil there are no air bubbles observed flowing from the tubingconnection at the inlet of the master divider valve.

The manual pump is also an efficientdevice to trouble shoot the divider block system tolocate blockage in divider blocks, tubing lines, andcylinder/packing injection points. The pump deliversfull pressure at minimum stroke for ease of use intight quarters.
