Maintenance and repairs
Alfa Laval AquaFirst does not require any specific maintenance.
The frequency of the inspections depends on the water hardness, temperature and flow rate.
•
Weekly inspection to check for leaks from pipes or components.
•
Weekly inspection to make sure that the operation control systems is stable and that the temperature
does not fluctuate. Temperature hunting causes unnecessary wear of valves, actuators.
•
The control box does not require any specific maintenance; annually check the electrical connections
tightening.
•
Annually check the control valve that no leaks are detected.
•
Regularly check lime scaling on the connected devices as scaling depends of water quality, hardness
and temperatures levels.
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.
Only replace any defective parts with the
original
spare parts.
Please contact your Alfa Laval distributor for spare parts, note serial number and model
designation.
