Frame - Carrier AquaEdge 19XRV Installation Instructions Manual

6. Disconnect all wires and cables that cross from the cooler
side of the machine to the condenser side, including:
a. temperature sensor cable at the waterbox (Fig. 10,
Item 5)
b. water-side transducer cables at the transducer
(Fig. 10, Item 4)
c. condenser transducer cable at the transducer
(Fig. 9, Item 7)
d. motor power wires at the motor terminal box
(Fig. 8, Item 3)
e. wires and cable housings at the power panel that
cross from the VFD to the power panel (Fig. 9,
Item 2).
7. Disconnect the tube sheet mounting brackets on the tube
sheets (Fig. 8, Item 5).
8. Rig the vessels apart.
To Separate Compressor from Cooler
1. Unbolt the compressor suction and discharge elbows
(Fig. 8, Items 1 and 10).
2. Cut the refrigerant motor cooling line at the location
shown (Fig. 8, Item 2).
3. Disconnect the motor refrigerant return line (Fig. 8,
Item 6).
4. Disconnect the following:
a. compressor oil sump temperature sensor cable
(Fig. 11, Item 4)
b. bearing temperature sensor cable (Fig. 11, Item 2)
c. motor temperature sensor cable (Fig. 11, Item 1)
d. wires and cable housings that cross from the power
panel to VFD and control panel (Fig. 9, Item 2)
e. discharge temperature sensor cable (Fig. 11, Item 6)
f. compressor oil sump pressure cable (Fig. 11,
Item 3)
g. compressor oil discharge pressure cable (Fig. 11,
Item 5)
h. guide vane actuator cable (Fig. 9, Item 1)
i. diffuser actuator cable (Frame 5 compressor and
Frame 4 units with split ring diffuser — Fig. 10,
Item 2)
j. diffuser pressure cable (Frame 5 compressor and
Frame 4 units with split ring diffuser — Fig. 11,
Item 8).
5. Disconnect the flared fitting for the oil reclaim line
(Fig. 8, Item 9).
6. Unbolt the compressor discharge elbow (Fig. 9, Item 6).
7. Cover all openings.
8. Disconnect motor power cables at the VFD lugs (Fig. 8,
Item 3).
9. Unbolt the compressor mounting from the cooler (Fig. 8,
Item 7).
10. Rig the compressor.
To Rig Compressor
NOTE: The motor end of the 19XRV compressor is heavy and
will tip backwards unless these directions are followed:
1. Cut two 4 in. x 6 in. wooden beams to the same length as
the compressor.
2. Drill holes into the beams and bolt them to the base of the
compressor using the compressor base mounting holes.
Additional Notes
1. Use O-ring lubricant on new O-rings when refitting.
2. Use gasket sealant on new gaskets when refitting.
3. Cooler and condenser vessels may be rigged vertically.
Rigging should be fixed to the tube sheets of all 4 corners
of the vessel.
