Maintenance and repairs
Cetetherm AquaEfficiency does not require any specific maintenance.
The frequency of the inspections depends on the water hardness, temperature and flow rate.
Weekly inspections:
•
Check for leaks on pipes and components
•
Check that the operation control system is stable and that the temperature does not fluctuate.
Temperature hunting causes unnecessary wear of valves, actuators.
Annually:
•
Check the control box electrical connections tightening.
•
Check the control valve for leaks.
•
Check the electric current requirement of the circulation pump.
•
Lime scaling on the connected devices.
Scaling of the secondary side will be evidenced by:
•
a high pressure drop on the secondary side of the exchanger
•
improper temperature range on the secondary side of the exchanger
•
low temperature difference between inlet and outlet on the primary side of the exchanger when the
control valve is fully open.
•
a warning from the controller if the unit is equipped with the scaling control or CIP option (F/B series
only).
Only replace any defective parts with the
original spare parts.
Please contact your Cetetherm distributor for spare parts, note serial number and model
designation.
Maintenance work must be carried out by a qualified and authorized technician.
Hazard of severe electrical shock or burn.
Before cleaning and servicing, disconnect power supplies.
Risk of burns. Let the pipes and exchanger cool down before starting out with maintenance work.
