● Discharge the condenser before the work involving the electric parts.
● Allow parts to cool.
● Do not expose the electric parts to water.

Some lead wires and pipes are bundled with bands. Cut the bands to undo the fastened pipes and lead wires if necessary. When bundling the
lead wires and pipes again, use new commercially available bands.
When removing the parts associated with water pipe work, drain the cylinder unit as necessary. Refer to "Draining the cylinder unit" on page 23.
