Remove the Manifold RTD
1. Relieve system pressure. Refer to Section 5, Relieving System Pressure.
See Figure 6‐6.
2. Isolate the pump from the manifold by rotating the isolation valve handle
to its full vertical position (valve closed).
3. Remove the three pump‐mounting bolts from the front of the pump body.
4. Rotate the top of the pump slightly toward the front of the melter, and then
pull the pump up and away from the manifold.
NOTE: The face of the pump body contains two M6 threaded holes.
Bolts can be threaded into these holes to gain leverage when removing
the pump.
5. Remove the air line from the back of the pump.
6. Lift the pump clear of the melter.
7. Remove the RTD from its retention slot.
8. To replace the RTD and pump, reverse the order of steps 2 through 7.
CAUTION! Before replacing the pump, ensure that the cross‐over tube is
in‐place between the pump and the manifold.
NOTE: Before replacing the RTD, apply thermal compound (P/N 1023441)
to the RTD and its retention slot. To avoid damage to the RTD, ensure that
the RTD is correctly inserted into its retention slot before replacing the pump.
