Checks Before Initial Start-Up; Field Setting - Panasonic Urban Multi U-8ME4XPQ Manual De Instalación

12.2. Checks before initial start-up

NOTE Remark that during the first running period of the unit,
required power input may be higher than stated on the
nameplate of the unit. This phenomenon originates
from the compressor that needs elapse of a 50 hours
run in period before reaching smooth operation and
stable power consumption.
Make sure that the circuit breaker on the power supply
panel of the installation is switched off.
Attach the power wire securely.
Introducing power with a missing N-phase or with a
mistaken N-phase will break the equipment.
After the installation, check the following before switching on the
circuit breaker:
1 The position of the switches that require an initial setting
Make sure that switches are set according to your application
needs before turning the power supply on.
2 Power supply wiring and transmission wiring
Use a designated power supply and transmission wiring and
make sure that it has been carried out according to the
instructions described in this manual, according to the wiring
diagrams and according to local and national regulations.
3 Pipe sizes and pipe insulation
Make sure that correct pipe sizes are installed and that the
insulation work is properly executed.
4 Air tight test and vacuum drying
Make sure the air tight test and vacuum drying were completed.
5 Additional refrigerant charge
The amount of refrigerant to be added to the unit should be
written on the included "Added Refrigerant" plate and attached
to the rear side of the front cover.
6 Insulation test of the main power circuit
Measure the insulation resistance and check if the value is in
accordance with relevant local and national regulations..
7 Installation date and field setting
Be sure to keep record of the installation date on the sticker on
the rear of the upper front panel according to EN60335-2-40.
and keep record of the contents of the field setting.
