2 Specific installer safety instructions
Unit installation (see "5 Unit installation" 4[ 6])
WARNING
Installation shall be done by an installer, the choice of materials and installation shall comply with the applicable legislation. In Europe, EN378 is the applicable standard.
Installation site (see "5.1 Preparing the installation site" 4[ 6])
CAUTION
▪Check if the installation location can support the unit's weight. Poor installation is hazardous. It can also cause vibrations or unusual operating noise.
▪Provide sufficient service space.
▪Do NOT install the unit so that it is in contact with a ceiling or a wall, as this may cause vibrations.
Connecting the refrigerant piping (see "6.2 Connecting the refrigerant piping" 4[ 9])
CAUTION
▪No brazing or welding on site for units with R32 refrigerant charge during shipment.
▪During installation of the refrigeration system, joining of parts with at least one part charged shall be performed taking into account the following requirements: inside occupied spaces non permanent joints are not allowed for R32 refrigerant except for site made joints directly connecting the indoor unit to piping. Site made joints directly connecting piping to indoor units shall be of non permanent type.
CAUTION
▪Use the flare nut fixed to the unit.
▪To prevent gas leakage, apply refrigeration oil only to the inside of the flare. Use refrigeration oil for R32.
▪Do NOT reuse joints.
CAUTION
▪Do NOT use mineral oil on flared part.
▪Do NOT reuse piping from previous installations.
▪NEVER install a drier to this R32 unit to guarantee its lifetime. The drying material may dissolve and damage the system.
WARNING
Connect the refrigerant piping securely before running the compressor. If the refrigerant piping is NOT connected and the stop valve is open when the compressor is run, air will be sucked in. This will cause abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.
CAUTION
▪Incomplete flaring may cause refrigerant gas leakage.
▪Do NOT re-use flares. Use new flares to prevent refrigerant gas leakage.
▪Use flare nuts that are included with the unit. Using different flare nuts may cause refrigerant gas leakage.
CAUTION
Do NOT open the valves before flaring is complete. This would cause refrigerant gas leakage.
DANGER: RISK OF EXPLOSION
Do NOT start the unit if it is vacuumed.
Charging refrigerant (see Charging refrigerant)
WARNING
The refrigerant inside the unit is mildly flammable, but normally does NOT leak. If the refrigerant leaks in the room and comes in contact with fire from a burner, a heater, or a cooker, this may result in fire, or the formation of a harmful gas.
Turn off any combustible heating devices, ventilate the room, and contact the dealer where you purchased the unit.
Do NOT use the unit until a service person confirms that the part from which the refrigerant leaked has been repaired.
WARNING
▪Only use R32 as refrigerant. Other substances may cause explosions and accidents.
▪R32 contains fluorinated greenhouse gases. Its global warming potential (GWP) value is 675. Do NOT vent these gases into the atmosphere.
▪When charging refrigerant, ALWAYS use protective gloves and safety glasses.
CAUTION
To avoid compressor breakdown, do NOT charge more than the specified amount of refrigerant.
WARNING
NEVER directly touch any accidental leaking refrigerant. This could result in severe wounds caused by frostbite.
Electrical installation (see "7 Electrical installation" 4[ 10])
WARNING
Appliance shall be installed in accordance with national wiring regulations.
WARNING
▪All wiring MUST be performed by an authorised electrician and MUST comply with the applicable legislation.
▪Make electrical connections to the fixed wiring.
▪All components procured on-site and all electrical construction MUST comply with the applicable legislation.
WARNING
▪If the power supply has a missing or wrong N-phase, equipment might break down.
▪Establish proper earthing. Do NOT earth the unit to a utility pipe, surge absorber, or telephone earth. Incomplete earthing may cause electrical shock.
▪Install the required fuses or circuit breakers.
▪Secure the electrical wiring with cable ties so that the cables do NOT come in contact with sharp edges or piping, particularly on the high-pressure side.
▪Do NOT use taped wires, stranded conductor wires, extension cords, or connections from a star system. They can cause overheating, electrical shock or fire.
▪Do NOT install a phase advancing capacitor, because this unit is equipped with an inverter. A phase advancing capacitor will reduce performance and may cause accidents.

3.1Indoor unit
Use an all-pole disconnection type breaker with at least 3 mm between the contact point gaps that provide full disconnection under overvoltage category III.
WARNING
If the supply cord is damaged, it MUST be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
WARNING
Do NOT connect the power supply to the indoor unit. This could result in electrical shock or fire.
WARNING
▪Do NOT use locally purchased electrical parts inside the product.
▪Do NOT branch the power supply for the drain pump, etc. from the terminal block. This could result in electrical shock or fire.
WARNING
Keep the interconnection wiring away from copper pipes without thermal insulation as such pipes will be very hot.

Do NOT perform the test operation while working on the indoor units.
When performing the test operation, NOT only the outdoor unit, but the connected indoor unit will operate as well. Working on an indoor unit while performing a test operation is dangerous.
CAUTION
Do NOT insert fingers, rods or other objects into the air inlet or outlet. Do NOT remove the fan guard. When the fan is rotating at high speed, it will cause injury.

5.1Preparing the installation site
WARNING
Make sure installation, servicing, maintenance and repair comply with instructions from Daikin and with applicable legislation (for example national gas regulation) and are executed only by authorised persons.
WARNING
The appliance shall be stored so as to prevent mechanical damage and in a well-ventilated room without continuously operating ignition sources (example: open flames, an operating gas appliance or an operating electric heater).
5.1.1Installation site requirements of the indoor unit
INFORMATION
The sound pressure level is less than 70 dBA.
▪Air flow. Make sure nothing blocks the air flow.
▪Drainage. Make sure condensation water can be evacuated properly.
▪Wall insulation. When conditions in the wall exceed 30°C and a relative humidity of 80%, or when fresh air is inducted into the wall, then additional insulation is required (minimum 10 mm thickness, polyethylene foam).
▪Wall strength. Check whether the wall or the floor is strong enough to support the weight of the unit. If there is a risk, reinforce the wall or the floor before installing the unit.
▪Spacing. Install the unit at least 1.8 m from the floor and keep the following requirements in mind for distances from the walls and the ceiling:
|
<![if ! IE]> <![endif]>≥30 |
≥50 |
≥50 |

(mm) |
5.1.2Additional installation site requirements of the outdoor unit in cold climates
Protect the outdoor unit against direct snowfall and take care that the outdoor unit is NEVER snowed up.
In heavy snowfall areas it is very important to select an installation site where the snow will NOT affect the unit. If lateral snowfall is possible, make sure that the heat exchanger coil is NOT affected by the snow. If necessary, install a snow cover or shed and a pedestal.
