2.2.3 Refrigerant

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

2.2.4 Water

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

2.2.5 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.
WARNING
If not factory installed, a main switch or other means for
disconnection, having a contact separation in all poles
providing full disconnection under overvoltage category III
condition, shall be installed in the fixed wiring.

Daikin Altherma - Low Temperature Split
4P313774-1 – 2012.05
WARNING
Only use copper wires.
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 compatible with the inverter (resistant to high
frequency electric noise) to avoid unnecessary
opening of the earth leakage protector.
Install power cables at least 1 meter away from televisions or radios
to prevent interference. Depending on the radio waves, a distance of
1 meter 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.
