2.1 For the installer
2.1.1 General
If you are NOT sure how to install or operate the unit, contact your dealer.
DANGER: RISK OF BURNING/SCALDING
▪ 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.
2 | General safety precautions
WARNING
Improper installation or attachment of equipment or accessories could result in
electrical 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 described 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. Possible risk: suffocation.
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.

2 | General safety precautions
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.
CAUTION
▪ 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.
2.1.2 Installation site
▪ Provide sufficient space around the unit for servicing and air circulation.
▪ Make sure the installation site withstands the weight and vibration of the unit.
▪ 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.
2.1.3 Refrigerant — in case of R410A or R32
If applicable. See the installation manual or installer reference guide of your
application for more information.
Installer reference guide

2 | General safety precautions
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 might 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 leak 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: Selfcombustion 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.
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.
Possible consequence: Self-combustion and explosion of the compressor because of
oxygen going into the operating compressor.
▪ In case recharge is required, see the nameplate of the unit. It states the type of
refrigerant and necessary amount.
EBLA09~16DA + EDLA09~16DA
Daikin Altherma 3 M
4P620241-1 – 2020.06
▪ 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:

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
electrical shock or fire.
▪ When installing the earth leakage protector, make sure it is compatible with the
inverter (resistant to high frequency electric noise) to avoid unnecessary opening
of the earth leakage protector.
CAUTION
▪ When connecting the power supply: connect the earth cable first, before making
the current-carrying connections.
▪ When disconnecting the power supply: disconnect the current-carrying cables
first, before separating the earth connection.
▪ The length of the conductors between the power supply stress relief and the
terminal block itself must be as such that the current-carrying wires are tautened
before the earth wire is in case the power supply is pulled loose from the stress
relief.
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
above.
▪ 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.

In case of freeze protection by glycol:
WARNING
Ethylene glycol is toxic.
WARNING
Due to the presence of glycol, corrosion of the system is possible. Uninhibited glycol
will turn acidic under the influence of oxygen. This process is accelerated by the
presence of copper and high temperatures. The acidic uninhibited glycol attacks
metal surfaces and forms galvanic corrosion cells that cause severe damage to the
system. Therefore it is important that:
▪ the water treatment is correctly executed by a qualified water specialist,
▪ a glycol with corrosion inhibitors is selected to counteract acids formed by the
oxidation of glycols,
▪ no automotive glycol is used because their corrosion inhibitors have a limited
lifetime and contain silicates which can foul or plug the system,
▪ galvanized pipes are NOT used in glycol systems since the presence may lead to
the precipitation of certain components in the glycol's corrosion inhibitor.
