Installer reference guide

1 General safety precautions

1.2 For the installer

1.2.1 General

If you are not sure how to install or operate the unit, contact your dealer.

NOTICE

Improper installation or attachment of equipment or accessories could result in electric shock, short-circuit, leaks, fire or other damage to the equipment. Only use accessories, optional equipment and spare parts made or approved by Daikin.

WARNING

Make sure installation, testing and applied materials comply with applicable legislation (on top of the instructions descr bed in the Daikin documentation).

CAUTION

Wear adequate personal protective equipment (protective gloves, safety glasses,…) when installing, maintaining or servicing the system.

WARNING

Tear apart and throw away plastic packaging bags so that nobody, especially children, can play with them. Poss ble risk: suffocation.

DANGER: RISK OF BURNING

▪ Do NOT touch the refrigerant piping, water piping or

internal parts during and immediately after operation. It could be too hot or too cold. Give it time to return to normal temperature. If you must touch it, wear protective gloves.

▪ Do NOT touch any accidental leaking refrigerant.

WARNING

Provide adequate measures to prevent that the unit can be used as a shelter by small animals. Small animals that make contact with electrical parts can cause malfunctions, smoke or fire.

CAUTION

Do NOT touch the air inlet or aluminium fins of the unit.

NOTICE

▪ Do NOT place any objects or equipment on top of the

unit.

▪ Do NOT sit, climb or stand on the unit.

NOTICE

Works executed on the outdoor unit are best done under dry weather conditions to avoid water ingress.

In accordance with the applicable legislation, it might be necessary to provide a logbook with the product containing at least: information on maintenance, repair work, results of tests, stand-by periods,…

Also, at least, following information must be provided at an accessible place at the product:

▪ Instructions for shutting down the system in case of an emergency

▪ Name and address of fire department, police and hospital

▪ Name, address and day and night telephone numbers for

obtaining service

In Europe, EN378 provides the necessary guidance for this logbook.

1.2.2 Installation site

▪ Provide sufficient space around the unit for servicing and air

circulation.

▪ Make sure the installation site withstands the unit's weight and

vibration.

▪ Make sure the area is well ventilated. Do NOT block any

ventilation openings.

▪ Make sure the unit is level.

Do NOT install the unit in the following places:

▪ In potentially explosive atmospheres.

▪ In places where there is machinery that emits electromagnetic

waves. Electromagnetic waves may disturb the control system, and cause malfunction of the equipment.

▪ In places where there is a risk of fire due to the leakage of

flammable gases (example: thinner or gasoline), carbon fibre, ignitable dust.

▪ In places where corrosive gas (example: sulphurous acid gas) is

produced. Corrosion of copper pipes or soldered parts may cause the refrigerant to leak.

1.2.3 Refrigerant

If applicable. See the installation manual or installer reference guide of your application for more information.

NOTICE

Make sure refrigerant piping installation complies with applicable legislation. In Europe, EN378 is the applicable standard.

NOTICE

Make sure the field piping and connections are not subjected to stress.

WARNING

During tests, NEVER pressurize the product with a pressure higher than the maximum allowable pressure (as indicated on the nameplate of the unit).

WARNING

Take sufficient precautions in case of refrigerant leakage. If refrigerant gas leaks, ventilate the area immediately. Possible risks:

▪ Excessive refrigerant concentrations in a closed room

can lead to oxygen deficiency.

▪ Toxic gas may be produced if refrigerant gas comes

into contact with fire.

DANGER: RISK OF EXPLOSION Pump down – Refrigerant leakage. If you want to pump

down the system, and there is a leakage in the refrigerant circuit:

▪ Do NOT use the unit's automatic pump down function,

with which you can collect all refrigerant from the system into the outdoor unit. Possible consequence: Self-combustion and explosion of the compressor because of air going into the operating compressor.

▪ Use a separate recovery system so that the unit's

compressor does NOT have to operate.

Installer reference guide

4P482333-1 – 2017.03

1 General safety precautions

WARNING

Always recover the refrigerant. Do NOT release them directly into the environment. Use a vacuum pump to evacuate the installation.

NOTICE

After all the piping has been connected, make sure there is no gas leak. Use nitrogen to perform a gas leak detection.

NOTICE

▪ To avoid compressor breakdown, do NOT charge more

than the specified amount of refrigerant.

▪ When the refrigerant system is to be opened,

refrigerant must be treated according to the applicable legislation.

WARNING

Make sure there is no oxygen in the system. Refrigerant may only be charged after performing the leak test and the vacuum drying.

▪ In case re-charge is required, refer to the nameplate of the unit. It

states the type of refrigerant and necessary amount.

▪ The unit is factory charged with refrigerant and depending on pipe

sizes and pipe lengths some systems require additional charging of refrigerant.

▪ Only use tools exclusively for the refrigerant type used in the

system, this to ensure pressure resistance and prevent foreign materials from entering into the system.

▪ Charge the liquid refrigerant as follows:

If Then

A siphon tube is present

(i.e., the cylinder is marked with "Liquid filling siphon attached")

A siphon tube is NOT present Charge with the cylinder upside

Charge with the cylinder upright.

down.

WARNING

Take sufficient precautions in case of brine leakage. If brine leaks, ventilate the area immediately and contact your local dealer.

WARNING

The ambient temperature inside the unit can get much higher than that of the room, e.g. 70°C. In case of a brine leak, hot parts inside the unit can create a hazardous situation.

WARNING

The use and installation of the application MUST comply with the safety and environmental precautions specified in the applicable legislation.

1.2.5 Water

If applicable. See the installation manual or installer reference guide of your application for more information.

NOTICE

Make sure water quality complies with EU directive 98/83EC.

1.2.6 Electrical

DANGER: RISK OF ELECTROCUTION

▪ Turn OFF all power supply before removing the

switch box cover, connecting electrical wiring or touching electrical parts.

▪ Disconnect the power supply for more than 1 minute,

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.

▪ Do NOT touch electrical components with wet hands.

▪ Do NOT leave the unit unattended when the service

cover is removed.

▪ Open refrigerant cylinders slowly.

▪ Charge the refrigerant in liquid form. Adding it in gas form may

prevent normal operation.

CAUTION

When the refrigerant charging procedure is done or when pausing, close the valve of the refrigerant tank immediately. If the valve is not closed immediately, remaining pressure might charge additional refrigerant.

Possible consequence: Incorrect refrigerant amount.

1.2.4 Brine

If applicable. See the installation manual or installer reference guide of your application for more information.

WARNING

▪ ONLY use copper wires.

▪ Make sure the field wiring complies with the applicable

legislation.

▪ All field wiring must be performed in accordance with

the wiring diagram supplied with the product.

▪ NEVER squeeze bundled cables and make sure they

do not come in contact with the piping and sharp edges. Make sure no external pressure is applied to the terminal connections.

▪ Make sure to install earth wiring. Do NOT earth the unit

to a utility pipe, surge absorber, or telephone earth. Incomplete earth may cause electrical shock.

▪ Make sure to use a dedicated power circuit. NEVER

use a power supply shared by another appliance.

▪ Make sure to install the required fuses or circuit

breakers.

▪ Make sure to install an earth leakage protector. Failure

to do so may cause electric shock or fire.

▪ When installing the earth leakage protector, make sure

it is compat ble with the inverter (resistant to high frequency electric noise) to avoid unnecessary opening of the earth leakage protector.

NOTICE

Precautions when laying power wiring:

▪ Do not connect wiring of different thicknesses to the

power terminal block (slack in the power wiring may cause abnormal heat).

▪ When connecting wiring which is the same thickness,

do as shown in the figure below.

▪ For wiring, use the designated power wire and connect

firmly, then secure to prevent outside pressure being exerted on the terminal board.

▪ Use an appropriate screwdriver for tightening the

terminal screws. A screwdriver with a small head will damage the head and make proper tightening impossible.

▪ Over-tightening the terminal screws may break them.

Install power cables at least 1metre away from televisions or radios to prevent interference. Depending on the radio waves, a distance of 1metre may not be sufficient.

WARNING

▪ After finishing the electrical work, confirm that each

electrical component and terminal inside the electrical components box is connected securely.

▪ Make sure all covers are closed before starting up the

unit.

NOTICE

Only applicable if the power supply is three‑phase, and the compressor has an ON/OFF starting method.

If there exists the possibility of reversed phase after a momentary black out and the power goes on and off while the product is operating, attach a reversed phase protection circuit locally. Running the product in reversed phase can break the compressor and other parts.
