Maintenance and cleaning
The rotary heat exchanger must be regularly checked for contamination and damage every 6 months.
The following must be checked:
- Tension of drive belt
- Quality of bearings (assess by bearing noise)
- Condition of casing
The cleaning process consists of three steps. First, rinse the heat exchanger with water using a high-pressure cleaner to
remove dust, particles, deposits etc. Then, use detergent to clean the heat exchanger. As a third step, remove the detergent
with water. Make sure that the nozzle of the high-pressure cleaner is adjusted to a plain jet.
Rotary Heat Exchanger Cleaning Procedure:
1.
Place the nozzle at a distance of approximate 300 mm (11”) from the heat exchanger.
2.
Have the nozzle adjusted to plane jet.
3.
Vary the spray angle b 30 and -
30 degrees from the openings at a distance of 300 mm (11.81”)
from the entrance
4.
Spray the whole wheel. Don’t forget to rotate the wheel in order to clean the parts hidden behind the framework.
5.
Let the heat exchanger air-dry.
6.
Spray the heat exchanger with detergent (YES/Fairy) with a low-pressure sprayer.
7.
Repeat point 1-5 in order to remove all detergent.
Allow heat exchanger to dry before installation!
