A 140mL aluminum tank with a ball valve may substitute for the flush bottle in normal and unattended
injections. The ball valve allows injection to continue while the valve is closed.
Figure 5:
140mL tank with ball valve.
When possible, attach the
graduated flush bottle for easy
measurement of flushed fluid.
If left unattended under any
circumstances, place the flush bottle
or tank in a basin to prevent
accidental spills.

Use a spill basin to guard
against spills and overflow.
Pre-Injection Check
1.
Check for leaks.
Before sending fluid straight to the cable, make sure each part of the injection assembly is leak-free. If
any leaks are found in the following process, close all valves, relieve pressure, and fix the leak.
Double-check that
all
valves on the feed tank, flow meter, tubing, and gas tank are closed.
Open the valve on the feed tank’s injection port. This will send fluid to the liquid flow meter. Wait for
three to four seconds and watch for leaks.
Open the valve on the liquid flow meter. This will send fluid to the inline ball valve. Wait for three to
four seconds and watch for leaks.
If no leaks are seen in the assembly, open the ball valve to send fluid to the injection tool. Watch for
leaks coming from the injection tool or the interface between the tool and the IA.
