Rittal HD air/water heat exchangers
Nature and extent of the work to be performed:
Check the air/water heat exchanger for damage, e.g.
scratched surfaces or damaged seals, at regular inter-
vals.
Eliminate scratches using a surface polish.
Replace any damaged seals and check all tightening
torques specified in these instructions at regular inter-
vals.
Only in this way is it possible to guarantee a reliable
and hygiene-compliant seal between the air/water
heat exchanger and the enclosure.
Check the area around the air/water heat exchanger
for any signs of corrosion, as this could lead to corro-
sion of the unit itself.
The installed fan is mounted on ball bearings, protected
against moisture and dust, and fitted with a temperature
monitor. The life expectancy is at least 30,000 operating
hours. If dirt is present in the cooling water, a filter must
be fitted. Maintenance interval: 2,000 operating hours.

Emptying, storage and disposal
During storage, the air/water heat exchanger must stand
upright.
Disposal can be performed at the Rittal plant.
Please contact us for advice.
Emptying:
During storage and transportation below freezing point,
the air/water heat exchanger should be drained com-
pletely in the water supply direction using compressed
air. To this end, the temperature in the area of the fan air
intake must be raised above the set value by artificial
means (e.g. with a hot air gun), so that the magnetic
valve opens.
Note:
Do not make any changes to the air/water
heat exchanger other than those described in
these instructions or associated instructions.
Note:
The air/water heat exchanger must not be
subjected to temperatures above +70°C dur-
ing storage.
