R410A.

  Using existing parts (for R22 or R407C) can cause the unit 

failure and serious accidents due to burst of the refrigerant 

circuit.

• Tighten the flare nut by torque wrench with specified 

method.

  If the flare nut were tightened with excess torque, this may 

cause burst and refrigerant leakage after a long period.

• Do not open the operation valves for liquid line and 

gas line until completed refrigerant piping work, air 

tightness test and evacuation.

  If the compressor is operated in state of opening operation 

valves before completed connection of refrigerant piping 

work, air can be sucked into refrigerant circuit, which can 

cause bust or personal injury due to anomalously high 

pressure in the refrigerant.

• The electrical installation must be carried out by the 

qualified electrician in accordance with “the norm for 

electrical work” and “national wiring regulation”, and 

the system must be connected to the dedicated 

circuit.

  If the power supply is not shut off, there is a risk of electric 

shocks, unit failure or personal injury due to the unexpected 

start of fan.

• Stop the compressor before disconnecting refrigerant 

pipes in case of pump down operation.

  If disconnecting refrigerant pipes in state of opening 

operation valves before compressor stopping, air can be 

sucked, which can cause burst or personal injury due to 

anomalously high pressure in the refrigerant circuit

• Only use prescribed optional parts. The installation 

must be carried out by the qualified installer.

  If you install the system by yourself, it can cause serious 

trouble such as water leaks, electric shocks, fire.

• Ensure that no air enters in the refrigerant circuit 

when the unit is installed and removed.

  If air enters in the refrigerant circuit, the pressure in the 

refrigerant circuit becomes too high, which can cause burst 

and personal injury.

• Do not processing, splice the power cord, or share a 

socket with other power plugs.

  This may cause fire or electric shock due to defecting 

contact, defecting insulation and over-current etc.

• Do not bundling, winding or processing for the power 

cord. Or, do not deforming the power plug due to 

tread it.

protections.

  Touching rotating equipments, hot surfaces or high voltage 

parts can cause personal injury due to entrapment, burn or 

electric shocks.

• Do not perform any change of protective device itself 

or its setup condition.

  The forced operation by short-circuiting protective device of 

pressure switch and temperature controller or the use of 

non specified component can cause fire or burst.

• Use the circuit breaker with sufficient breaking 

capacity.

  If the breaker does not have sufficient breaking capacity, it 

can cause the unit malfunction and fire.

• Earth leakage breaker must be installed.

  If the earth leakage breaker is not installed, it can cause 

electric shocks.

• Install isolator or disconnect switch on the power 

supply wiring in accordance with the local codes and 

regulations.
