Check that the hydraulic systems and the freon installation are complete
and
and ready for operation and that the correct amount of heating or cooling
medium has been introduced to start up the unit.
Check that earthing cables are in place, connecting the control systems
to the ventilation ducts.
Check that the condensate traps and drainage systems from the
condensate gutter are fitted.
Check the connections of the peripheral devices (T1 terminal) - as the
optional equipment of the control panel, such as operator panels and
some temperature sensors, may differ depending on the chosen
configuration, check that their connection is made through a dedicated
T1 terminal, has
documentation (pay particular attention to the correct connection of the
24V power supply
(pay particular attention to the correct connection of the 24V power
supply and Modbus communication cables, as their confusion may
damage the entire communication bus of the control unit)
Check that the power supply is correctly connected to the main switch -
the correct voltage must be applied to the block switchboard in
accordance with the unit's wiring diagram in the relevant section of its
technical data sheet or User's Manual (DTR).
Check that the power supply to the electric heater (if any) is correctly
connected - the appropriate voltage must be applied to the heater
switchboard in accordance with the wiring diagram of the appliance in
the relevant section of its technical data sheet or the User's Manual
(DTR).
During operation of the air handling unit (and also prior to its initial start-
up), when the heater is not operating, dust may settle on the heating
elements. When the heater is switched on again, the heavy soiling can
cause a smell of burning dust or even a fire hazard.
Check the condition of the electrical connections, the condition of the
heating elements and the degree of dirt on a regular basis (annually),
especially before the first start-up and before the start of the heating
period. Remove any dirt with a hoover with a soft nozzle or compressed
air.
The operation of the overheating protection and the no-airflow protection
should also be checked regularly. The air velocity in the AHU during
heater operation should not be less than 1.5 m/s.
Check that the inspection panels are closed - the rotating parts of the
control panel can pose a risk to health and life when the protective
covers are removed
