Electrical Wiring - Daikin VAM350J7VEB Installer And User Reference Manual

Extreme bend. Do NOT bend the duct over 90°.
Multi bend
Reduced diameter. Do NOT reduce the duct diameter.
▪ The minimum bend radius for flexible ducts is as follows:
(Øduct/2)×1.5
▪ To prevent air leakage, wind aluminium tape around the section
where the duct joints and the ducts are connected.
▪ Install the opening of the supply air as far as possible from the
opening of the return air.
▪ Use ducts with a diameter that fit the unit model. See the data
book.
▪ Install the two outdoor ducts with down slope (slope ratio of 1 in
50 or more) to prevent entry of rain water. Also provide insulation
for both ducts, to prevent dew formation. (Material: 25 mm thick
glass wool)
▪ If the level of temperature and humidity inside the ceiling is always
high, install ventilation inside the ceiling.
▪ Insulate the duct and the wall electrically when a metal duct has to
penetrate the metal lattice and wire lattice or the metal lining of a
wooden structure wall.
▪ Install the ducts in a manner that the wind CANNOT blow inside
the ducting.

INFORMATION
Also read the precautions and requirements in the
"General safety precautions" chapter.
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 the site and all electrical
construction MUST comply
legislation.
Precautions when connecting electrical
wiring
DANGER: RISK OF ELECTROCUTION
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, MUST be installed in the fixed wiring.
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 compatible with the inverter (resistant to high
frequency electric noise) to avoid unnecessary opening
of the earth leakage protector.
