5.5 Maintenance
•
The recommended inspection interval is 6 months.
•
Make sure that the water side connections of the coil do not leak.
•
Make sure that the heat transfer surfaces of the coil are clean and intact.
•
Clean the coil gently with a brush, compressed air or a vacuum cleaner.
•
Bleed the coil and check the operation of the anti-freezing thermostat at the beginning of each
heating season.
•
A damaged coil must be repaired in place, sent to the manufacturer to be repaired or replaced.
CAUTION
If the coil is not used during the heating season, water must be drained from it or it has to
be filled with a water-glycol mixture to avoid freezing. The coil does not drain fully through
the drain screw; 20 to 30% of the total water volume remains in the coil. To drain water
from the coil, you can, for example, blow compressed air through the bleed screw,
observing the maximum permissible operating pressure.
