2.8 COMMISSIONING MODE.
Important: the customised connection of the
interface circuits could pose safety risks: any
changes to the control panel must maintain
the equipment compliance with local regula-
tions. Precautions must be taken to prevent
accidental electrical contacts between circuits
fed by different sources:
• the selection and features of the conductor
insulation must ensure double electrical
insulation.
• In case of accidental disconnection, the con-
ductor fixing between different conductors
and/or in the control panel must prevent any
contact between the conductor ends and a live
active component.
Refer to the wiring diagrams of the Audax Top
18-21 ErP units provided with the unit, for the
possible configuration wiring.
2.9 CHECKS BEFORE STARTING THE
UNIT.
Do not start the heat pump without reading, and
fully understanding, the operating instructions
and without having performed the following
pre-start checks:
• Make sure that all electrical connections are
properly tightened.
• Make sure that the unit is on a flat surface and
securely fastened.
• Verify that the hydraulic circuit has sufficient
water flow and that the connection pipes cor-
respond to the installation diagram.
• Make sure there are no water leaks. Verify the
correct operation of the valves installed.
• All panels must be assembled and securely
fastened with appropriate screws.
• Make sure there is sufficient space for the as-
sistance and maintenance operations.
• Make sure there are no coolant leaks.
• Verify that the electricity source complies with
the data on the unit plate, wiring diagrams and
other documents relating to the unit itself.
• Make sure the power supply complies with the
applicable regulations.
• Make sure that the compressor can freely move
on the assembly springs.
Attention:
• The heat pump commissioning and start-up
must be monitored by a qualified refrigera-
tion technician.
• The start-up and operating tests must be per-
formed with a thermal load applied and with
water circulating in the water heat exchanger.
• All set-point adjustments and control tests
must be performed before starting the unit.
Make sure that all safety devices are working.
In particular, make sure that the high pressure
switches work constantly and that the alarms are
acknowledged.
N.B.: failure to comply with the Manufacturer’s
instructions (electrical connections, hydraulic
conn installation), automatically voids
the Manufacturer’s warranty.
