Ensure that the electrical cable used for power supply
and control of the system is unable to come into
contact with either service valves or piping work which
are not insulated.
9-10-2. Electrical wiring
When installation is complete, check that all power
supply and interconnecting wiring has been
appropriately protected.
9-10-3. Refrigerant piping
When refrigerant and drain piping have been
completed. Ensure that all pipework is fully insulated
and apply finishing tape to seal the insulation.
9-10-4. Check and Test Operation
• Pressure of R410A is approx. 1.6 times of that of

gas leakage may occur at the cases such as
pressure rise during operation.
Therefore, be sure to test the piping connections for
leakage.
• Check the flare nut connections, valve stem cap
connections and service port cap fittings for gas
leak with a leak detector or soap water.
