MANDÍK CPV Installation, commissioning, and maintenance
Airflow of 1 m/s must be maintained at a minimum at all times for electric heaters under all
operating conditions and modes to ensure the heat from the heating elements is dissipated.
The electric heat exchanger is sized for 3~400 V / 50 Hz mains and may contain multiple
sections.
The surface temperature of the heating rods under operating conditions significantly exceeds
the safe contact temperature of 60°C. Allow a sufficient amount of time to enable the heating
rods to cool before starting any work or activities on the heaters!
Any intervention into electrical heaters may only be performed by personnel with professional
qualifications under the valid legislation in the country of installation of the equipment.
Check the condition of the heating elements and for any contamination, vacuum to clean as
needed.
It is necessary to check the operation of the operating thermostat and the alarm thermostat,
e.g. by manually adjusting the airflow.
