DANGER:
Before doing any maintenance work
on the Votator II, lock out and tag out equipment.
1. Check to insure all supply lines to unit are closed and
locked and tagged out.
2. Make sure that entire unit is purged of fluids (product,
coolant, refrigerant, etc.)
3. Remove mutator shaft and drive end head as
described in this section.
DANGER:
Before removing the heat exchanger
tube from the jacket, all refrigerant must be
evacuated from the jacket assembly.
4. Remove locking latch and associated hardware that
holds front cover in place.
5. Remove the eight (8) 3/8-inch bolts that hold
removable tube to jacket. See Figure 33.
6. Take four (4) bolts and thread them into the “B”
holes. The “B” holes are located at the 12, 3, 6, and 9
o’clock locations. DO NOT TIGHTEN!
7. Using an X pattern, gradually tighten bolts to
withdraw tube from jacket. Considerable effort may
be needed to overcome any stickiness.
If tube does not start to pull away from jacket as bolts
are tightened, stop and do the following:
• Make sure product head on drive end is removed.
• Place a block of wood across drive end of tube and
apply pressure to force tube opposite the drive end.
• When tube is loose, use bolts to complete removal.
• If tube cannot be budged, contact SPX Process
Equipment.
8. Pull tube out of jacket. Care should be taken to avoid
marring jacket cylinder during heat transfer tube
removal. Mark tube and jacket so that tube can be
reinstalled in same jacket. See Figure 34. On BWS or
liquid units, install a new packing ring.
