1. Perform Shutdown, page
NOTE: Whip hose must be connected. NOTE: NOTE:
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).

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.
