9-2 Disassembly and Assembly
The following gives the procedure if each part must be disassembled or assembled to check the seal, replace parts, or
clean the device.
Disassembling the Probe
Do not disassemble the probe if possible, in order to maintain airtightness. Before disas-
sembling the probe, be sure to turn off the power. Additionally, before disassembling a
probe that is pulled out of the water, be sure to wipe off all moisture.
