DISASSEMBLY PROCEDURE

<Preparation for the repair service>
● Prepare the proper tools.
● Prepare the proper protectors.
● Provide adequate ventilation.
● After stopping the operation of the hydrobox and outdoor unit, turn off all the power-supply breaker.
● Discharge the condenser before the work involving the electric parts.
● Allow parts to cool.
● Do not expose the electric parts to water.
● When replacing or servicing water circuit parts, drain system first.
Check individual illustrations and positions of the parts by referring to the parts catalogue.
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 hydrobox as necessary. (Refer to "Draining the Hydrobox"
on page 21.)
When draining the hydrobox, keep water from splashing on the internal parts (mainly electric parts and insulations).
