1. Perform Shutdown, page 49 .
Note
Whip hose must be connected.
2. Remove cover (CV).
3. Disconnect system wires from the Reactor.
4. Disconnect hose wires (HW) from terminal block
(TB), see Fig 3.
5. Using an ohmmeter, check between the hose
wires (HW). There should be continuity.
6. If hose fails test, retest at each length of hose
from the system out to the gun, including whip
hose, until failure is isolated.
7. Reconnect wires and install cover (CV).

4. Retest at each length of hose, including whip
hose, until failure is located.
5. If the FTS is not reading properly at the end of
the hose, connect FTS directly to RTD cable (C)
at the manifold.
6. If the FTS reads properly at the manifold but
not at the end of the hose, check cable (C)
connections. Verify they are tight.

To assist in taking readings, order RTD
Test Kit 24N365. Kit includes two cables:
one cable with a compatible female M8
connector and another cable with a male
M8 connector. Both cables have stripped
wire at the other end for easy test probe
access.
