ONICON’ s INSTL1 

Standard 

Installation Hardware

 kit for black iron 

pipe is for use in a drained, non-
pressurized system. The access hole is 
drilled (1”  minimum) prior to installation 
of the 1”  NPT branch outlet, close nipple 
and full port ball valve. Once the 
isolation valve is installed, the piping 
system can be flushed and pressurized. 
The flow meter may now be inserted or 
removed by hand without having to drain 
the system. Please read all instructions 
before proceeding with meter insertion. 
 
ONICON’ s INSTL2 

Hot Tap Installation 

Hardware

 kit for black iron pipe offers 

an alternative installation when it is not 
practical to drain or relieve the pressure 
in the system. In this case, a 1¼”  branch outlet, close nipple and 1¼”  full port ball valve are 
installed first. Then, a hot tap drilling apparatus can be used to drill a 1”  diameter hole through 
the valve, without shutting down or draining the pipe. 
 

(See Appendix A for List of Available Onicon Installation Hardware Kits for other types of pipe 
materials and applications.) 

 
 

After fitting the necessary plumbing hardware, flush the entire system so that it is free of flux, 
solder and slag. Prepare to install the flow meter by loosening the clamping nut and withdrawing 
the turbine assembly fully into the hot tap adapter. Next, thread the adapter on to the ball valve 
using a paste type thread sealant. Do not use Teflon tape because torn strands of the tape may 
wind around the turbine, slowing down or even stopping the turbine. 

 
 

Check the installation for leaks by slightly opening the ball valve.  An ‘ O’  ring in the hot tap 
adapter seals the meter stem against leakage. If there are any leaks around the clamping nut or 
stem, 

DO NOT ATTEM PT TO STOP THE LEAKAGE BY OVERTI GHTENI NG THE 

CLAM PI NG NUT.  Damage to this nut or the clamping ring under the nut may prevent 
the assembly from properly holding the meter in the pipe.

 The clamping nut is not part of the 

sealing mechanism. Any leaks in this area indicate that the ‘ O’  ring is not sealing properly and 
you must contact the factory for assistance.
