Troubleshooting, Spare Parts and Service
Troubleshooting
When performing any handling or troubleshooting of the air-
handling device, the power supply of the entire distribution
board must be disconnected using the main switch. When
performing inspections, pay increased attention to the correct
functioning of the protection devices (SUMX mixing set, motor
thermo-contacts and electric heater thermo-contacts). Verify
the correct functioning of evaluating, protection and switch-
ing devices. Check the control signal. Check the terminals
for proper tightening, both on the peripheral device side and
control unit side.
Regular Inspections
Service inspections of the entire air-handling system must be
performed at least twice a year (unit transition from winter to
summer operating mode).
In addition to these, extra inspections must also be performed
after a unit failure, natural disaster or emergencies.
Maintenance of the control unit includes just regular cleaning
and inspection of the screw connections – wires, grounding,
component fixing, etc. Internal parts of the unit must be
cleaned of dust and any other dirt at the specified mainte-
nance intervals.
If the control unit is equipped with a fan fitted with a filter
(outdoor version), change the filter once a year.
If necessary, clean the face panel of the unit's box using a wet
cloth. Use common cleaners.
If the control unit is equipped with a filter fan (external version),
replace the filter once a year.
When changing over to the summer operating mode, drain the
heating water circuit; the mixing set pump must be discon-
nected. To do so, turn the disconnector to the "Off" position.
(Otherwise, ensure regular turning of the pump to prevent the
pump seizing; operating the pump without water can damage
it). In the winter operating mode, the pump must be activated
using the reverse order of steps, i.e. turned "On" and checked
for proper operation.
The same procedure must be performed when the water
cooler is being shut down for a season or reactivated. (Note
that the water cooler pump does not turn the system).
