Error Codes When Charging Refrigerant; Checks After Charging Refrigerant; Connecting The Electrical Wiring; Precautions When Connecting Electrical Wiring - Daikin RXYTQ8T7YF Installer And User Manual

INFORMATION
The manual refrigerant charge operation will automatically
stop within 30 minutes. If charging is not completed after
30 minutes, perform the additional refrigerant charging
operation again.

"8 Commissioning" on page 38.
INFORMATION
▪ When a malfunction is detected during the procedure
(e.g., in case of closed stop valve), a malfunction code
will be displayed. In that case, refer to
codes when charging refrigerant" on page 27
solve the malfunction accordingly. Resetting the
malfunction can be done by pushing BS3. The
procedure can be restarted from
manually charge refrigerant" on
▪ Aborting the manual refrigerant charge is possible by
pushing BS3. The unit will stop and return to idle
condition.

Error codes when charging refrigerant

If a malfunction occurs, close valve A immediately. Confirm the
malfunction code and take corresponding action,
problems based on error codes" on
6.7.8

Checks after charging refrigerant

▪ Are all stop valves open?
▪ Is the amount of refrigerant, that has been added, recorded on the
refrigerant charge label?
NOTICE
Make sure to open all stop valves after (pre-) charging the
refrigerant.
Operating with the stop valves closed will damage the
compressor.

6.8.1 Precautions when connecting electrical
wiring
DANGER: RISK OF ELECTROCUTION
WARNING
All field wiring and components must be installed by a
licensed electrician and must comply with the applicable
legislation.
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.

WARNING
▪ ONLY use copper wires.
▪ Make sure the field wiring complies with the applicable
legislation.
▪ All field wiring must be performed in accordance with
in
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 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
Do not operate the unit until the refrigerant piping is
complete. Running the unit before the piping is ready will
break the compressor.
NOTICE
If the power supply has a missing or wrong N-phase,
equipment will break down.
NOTICE
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.
NOTICE
Never remove a thermistor, sensor, etc., when connecting
power wiring and transmission wiring. (If operated without
thermistor, sensor, etc., the compressor may break down.)
NOTICE
▪ The reversed phase protection detector of this product
only functions
Consequently
performed during normal operation of the product.
▪ The reversed phase protection detector is designed to
stop the product in the event of an abnormality when
the product is started up.
▪ Replace two of the three phases (L1, L2, and L3)
during reverse-phase protection abnormality.
