Disassembly for
Cleaning
The frequency of cleaning will depend upon the purity of the water being
used. The distilled water center should be inspected at frequent intervals
until cleaning intervals are determined. Disassemble, inspect, and clean the
distilled water center as follows:
1. Shut off and drain the Distilled Water Center (see Normal Operation).
2. Lift the top hinged cover up so that the unit can be serviced from the
top.
3. Remove the upper front panel by lifting the panel up and pulling it
out.
4. Remove the lower panel by reaching underneath the unit and pushing
the panel retaining strip up to disconnect it from the frame inside and
at the center of the unit and pulling the panel out at the bottom and
down.
5. Slide the vapor pipe connector toward the condenser to disconnect the
vapor pipe/evaporator cover/”Q” baffle assembly from the condenser.
Be careful not to damage the two O-rings in the collar.
6. Disconnect the low water cutoff electrical leads from the electrode
assemblies by pulling the lead clips up from the electrode assembly
terminals.
7. Remove the wing nuts securing the evaporator cover to the evaporator
and remove the evaporator cover.
8. Slide the vapor pipe connector off the portion of the vapor pipe
connecting to the condenser and inspect the O-rings inside the
connector for damage. Replace the O-rings if necessary.
9. Inspect the electrode assemblies for scale and clean as required.
10. Inspect the heating elements inside the evaporator for scale and the
interior of the evaporator for scale and clean as required.
11. Remove and clean the waste cup.
12. Remove and clean the constant level device.
