Electrical Part - flowair AURA HCS Series Installation And Operating Instruction

It is recommended to flush the piping system after its completion by bypassing the cooling equipment.
To prolong the life of the components, we recommend the use of additives for antifreeze mixtures, so-called corrosion
Glycol mixtures
V případě použití glykolových směsí:

The freezing point of glycol must be lower than the minimum evaporation temperature

The concentration of the mixture should not be higher than the calculated one stated on the nameplate, otherwise
the cooling capacity of the system will be reduced

Check the pH of the mixture, which should be approximately between 9.5 - 8

Check the pH value regularly (during maintenance)

In the case of an external hydromodule, make sure that the pump used and other circuit elements and seals are
suitable for working with refrigerated media (when using glycol).
It is not permissible to discharge a mixture of water and glycol into the sewer. Mixture Must be collected in special
packaging and disposed of in accordance with waste disposal regulations.

3.3. Electrical part

The equipment documentation also includes an electrical wiring diagram and the ACS System Manual, which is used to control
all functions of the cooling equipment.
The mains voltage and frequency must correspond to the values on the rating plate of the appliance. The supply voltage
should not exceed the values given in the wiring diagram for a short time, which is +/- 5% for the voltage; +/- 1% for frequency,
unless otherwise stated.
The supply cables must be adequately fused and dimensioned to correspond to the electrical performance characteristics
specified on the nameplate and the supplied electrical specifications in the wiring diagram.
The protective earth conductor, which interconnects the protective conductor, the earth lead and the conductive parts, must
comply with standard EN 60204-1. The connecting cable (earthed) must have a cross section of at least 10 mm2.
It is not permissible to mechanically load the supply terminals of the electrical switchboard.
The electrical connection must be carried out by qualified personnel in accordance with the local regulations in force.
Before connecting the equipment or servicing electrical parts, make sure that the main / safety switch is in the OFF position.
The system operator must ensure that the power supply is equipped with a disconnector, e.g. a mains switch with an
appropriate contact rating, and that the mains supply must also be equipped with a separate fuse and an emergency
switch. (all dimensioned according to the relevant approved project documentation of the electrical installation).
