    Adoption of R32 Refrigerant Original instruction This air conditioner adopts the HFC refrigerant (R32) which does not destroy the ozone layer. This outdoor unit is designed exclusively for use with R32 refrigerant. Be sure to use in combination with a R32 refrigerant indoor unit. CONTENTS SAFETY CAUTION ....................

  • Page 3: Safety Caution

    SAFETY CAUTION Please read carefully through these instructions that contain important information which complies with the Machinery Directive (Directive 2006/42/EC), and ensure that you understand them. Some of the details provided in these instructions differ from the service manual, and the instructions provided here take precedence.
  • Page 4 Definition of Protective Gear When the air conditioner is to be transported, installed, maintained, repaired or removed, wear protective gloves and “safety” work clothing. In addition to such normal protective gear, wear the protective gear described below when undertaking the special work detailed in the table below.

CAUTION CAUTION BURST HAZARD BURST HAZARD Open the service valves before the Open the service valves before operation, otherwise there might be the burst.
  • Page 7 Precaution for Safety The appliance shall be installed in accordance with national wiring regulations. Capacity shortages of the power circuit or an incomplete installation may cause an electric shock or fire. DANGER Before carrying out the installation, maintenance, repair or removal work, be sure to set the circuit breaker to the OFF position.
  • Page 8 When you access inside of the electric cover to repair electric parts, wait for about five minutes after turning off the breaker. Do not start repairing immediately. Otherwise you may get electric shock by touching terminals of high-voltage capacitors. Natural discharge of the capacitor takes Electric about five minutes.
  • Page 9 When performing repairs using a gas burner, replace the refrigerant with nitrogen gas because the oil that coats the pipes may otherwise burn. When repairing the refrigerating cycle, take the following measures. 1) Be attentive to fire around the cycle. When using a gas stove, etc., be sure to put out fire before work;...
  • Page 10 When the refrigerant gas leaks, find up the leaked position and repair it surely. If the leaked position cannot be found up and the repair work is interrupted, pump-down and tighten the service valve, otherwise the refrigerant gas may leak into the room. When gas touches to fire such as fan heater, stove or cocking stove, it may generate noxious gases, causing a fire though the refrigerant gas itself is innocuous.
  • Page 11 Only a qualified installer ( 1) or qualified service person ( 1) is allowed to install the air conditioner. If the air conditioner is installed by an unqualified individual, a fire, electric shocks, injury, water leakage, noise and/or vibration may result. Before starting to install the air conditioner, read carefully through the Installation Manual, and follow its instructions to install the air conditioner.
