3.7 Additional remarks
• The cables may carry voltage even when the unit is powered off.
• The action service switch on/off restarts the machinery/fan. Take appropriate precautions.
• All the main pressure bearing parts of the air heat exchanger (AHE) are designed according to PED
2014/68/EU and Harmonized standards only for internal pressure within the limits of maximum design
pressure (PS) and maximum operation temperature (TS) pointed out in the nameplate (positive pressure).
• The end user is responsible for adopting the suitable safety devices against overpressure and overheating
(i.e. safety valves).
• The stop/emergency stop device is not supplied by the manufacturer, because the total process risk may
increase or a new risk would be introduced by the action of a localized stop/e-stop system.
• S-models without service switches (and without SW or cabinet options): The end user is responsible for
securing the equipment, that is, for switching off the installation/machine where the fan is installed and for
securing it from being switched on again.
• The end user is in charge of the periodic inspection of the safety devices installed on the air heat
exchanger (AHE) according to the national regulations.
3.7 Additional remarks
Caution:
The venting/draining valve of the liquid coolers is not suitable for heat transfer fluids based on
potassium formiate. There is a danger of leakage.
When using heat transfer fluids based on potassium formiate, the piping system and venting/draining
valves of the heat transfer section must be adapted for the heat transfer fluid in question. Always
check this from documentation.
Follow the instructions of the heat transfer fluid supplier at installation, pressure testing, startup,
operation and maintenance.
Caution:
Only a skilled mechanic using proper tools and approach may discharge and assemble the motor.
The mechanic must perform the repair work according to the standard IEC-60079-19. Under the
period of guarantee, always return a faulty motor to the supplier. Do not demolish it.
Always use the spare part motor available from Fincoil LU-VE Oy to guarantee its applicability to the
operating conditions.
