3. Periodic inspection and maintenance
a. Inspect the machine weekly for damage.
b. Check the machine compound gauge daily to verify that there is no decline in vacuum
and record the vacuum value. If the vacuum is lower than the low limit, contact your
nearest authorized Johnson Controls Service Center immediately.
c. If the vacuum has dropped as a result of improper machine operation, contact your
nearest authorized Johnson Controls Service Center immediately.
CAUTION
Use care that foreign matter does not enter the drain valve and air vent valve in the water chamber
casing. Keep these valves fully open while the machine is in storage.
Hoisting the machine
When hoisting the machine, attach a shackle to each of the four eye plates. Lift the machine using
care that the angle formed by the wire is within 60 degrees, as shown in Figure 4.
Do not apply shock to the machine. The machine is a high-vacuum vessel containing a corrosive
solution. Use diligence in protecting the machine, as repair is labor intensive and costly.
Lift the machine horizontally. If the machine is inclined, the solution and refrigerant inside shifts
the unit, producing an offset load. This is can cause damage to the machine and pose a risk to the
machine installer or persons moving the unit.
Moving the machine on rollers
Plan the entrance for the machine from the following figure.
Do not incline the machine more than 10 degrees. If the machine has to be inclined more than 10
degrees, extract the solution and refrigerant beforehand.
Do not apply shock to the machine. The machine is a high-vacuum vessel containing a corrosive
solution. Use diligence in protecting the machine as repair is labor intensive and costly.
When a skid base is used to move the machine on rollers, secure the skid base and place the
machine legs evenly on the skid base before moving the machine on rollers.
