2 Specific installer safety instructions Charging refrigerant (see "6 Charging refrigerant" [ 4 9]) WARNING The appliance shall be stored in a room without WARNING continuously operating ignition sources (example: open The refrigerant inside the unit is mildly flammable, but flames, an operating gas appliance or an operating electric normally does NOT leak.
3 About the box WARNING About the box ALWAYS use multicore cable for power supply cables. Outdoor unit WARNING Use an all-pole disconnection type breaker with at least 3 mm between the contact point gaps that provide full 3.1.1 To remove the accessories from the disconnection under overvoltage category III.
4 Unit installation NOTICE The height of the wall on the outlet side of the outdoor unit MUST be ≤1200 mm. Do NOT install the unit in sound sensitive areas (e.g. near a bedroom), so that the operation noise will cause no trouble. Note: If the sound is measured under actual installation conditions, the measured value might be higher than the sound pressure level mentioned in "Sound spectrum"...
