Maintenance and repairs
16
HRS Hevac AquaSave 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.
Clean and disinfect the system at least once a year, see
16.1 Antibacterial treatment of the AquaSTOR.
Regularly:
The cleaning schedule for the exchanger will depend on the quality of the water and how much
demand is placed on the system.
Flush-out the tank on a regular basis.
Check regularly that the safety devices (like safety valve, etc.) are working properly.
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 that should not exceed 50 kPa on all
models (heat exchanger only).
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 our after sales company HeatExchangerSpares.com 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.
