Note: Re-tighten the connections after 48 hours of operation.
Also, it is indispensable to install an appropriate air flow control
device in the circuit (curtain, pallet, pressostat...) to prevent the
functioning of the battery in case of an air flow problem.
CIAT does not accept any responsibility in case of no respect of this
recommendation.
1) Take care not to operate the battery when the fan is not
running.
2) In the case of a 2-speed motor, regulation must be made so that
a reduction of air flow will automatically give a proportional
reduction in the battery output.
Example : 1500/750 rpm motor
30 kW battery output
At low speed, the battery output should not exceed 15 kW.
Possible faults
Numerous causes can lead to over-heating of the electrical heating
elements and to the subsequent tripping of the thermostat.
They are
• Operating the battery when the fan is not running
• Partial clogging of the filter
• Fan turning in the wrong direction (occurs frequently on
commissioning).
• Wrong positioning of the air inlet or outlet dampers
•
Insufficient tension of the fan/motor drive belt
