2 Specific installer safety

instructions

Always observe the following safety instructions and regulations.

Installation Manual

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.

WARNING

ALWAYS use multicore cable for power supply cables.

WARNING

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.

DANGER: RISK OF ELECTROCUTION

All electrical parts (including thermistors) are powered by the power supply. Do not touch them with bare hands.

DANGER: RISK OF ELECTROCUTION

Disconnect the power supply for more than 10 minutes, and measure the voltage at the terminals of main circuit capacitors or electrical components before servicing. The voltage MUST be less than 50VDC before you can touch electrical components. For the location of the terminals, see the wiring diagram.

5.1 Preparing 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).

5.1.1 Installation 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:

5.1.2 Additional 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.

5.2 Opening the indoor unit
