MAINTENANCE
A forklift can be used to remove the cross counterflow heat exchanger
from the Vallox Pureo TX 1300 and 1800 units. Ensure that there is
sufficient space for the forklift, so that maintenance work can be carried
out on the heat exchanger.
CLEANING
The cross counterflow heat exchanger must be regularly checked for
any accumulated dirt and dust. The cross counterflow heat exchanger
must also be checked for damage once in every 6 months. If there is
dirt or dust on the heat exchanger, these can be removed as follows:
• Aluminium cross counterflow heat exchangers can be cleaned with
water (cleaning pressure max. 5 bar).
• The cleaning can be carried out with cold or warm water (up to max.
70°C). Household cleaners may be used.
• Clean the heat exchanger on both sides!
• Do not bend the fins!
• When cleaning, ensure that the heat exchanger is not damaged
either mechanically or chemically.
IMPORTANT
Allow the heat
exchanger to dry before
installation!
5. Pull the heat exchanger latches forward and open them.
