If the vacuum cleaning of impurities while the coil remains in its place does not suffice, disconnect
it from the heating / cooling medium, remove it and clean it using a high-pressure cleaner.
Proceed with care so as not to damage the coil.
When cleaning the coil proceed in such a way so as to prevent impurities or moist from entering
the other parts of the appliance.
9.5. Cleaning the plastic heat recovery exchanger
The recommended period for cleaning the exchanger is approximately 30 to 50 thousand running
hours depending on the nature of the operating environment.
It is necessary to clean the exchanger when it shows only minimum signs of contamination.
After opening the door and unlocking the fixing elements, slide individual recovery exchanger
blocks out of the guide rails in the following order: size 650 – 1,2; 1100 – 1,2; 1600 - 1, 2; 2600
and 3600 - 1, 2, 3. Rinse the individual blocks with hot water containing detergent with maximum
temperature 70°C, alternatively use disinfectant in concentration recommended by the producer.
After letting them dry thoroughly, slide the individual heat recovery exchanger blocks back in in the
reversed order and secure them in place.
Check for the tight fit of the exchanger in the guide rails.
Do not expose the exchanger to ultraviolet light, store it in darkness if necessary.
Never clean the exchanger with agents that might contain organic solvents - there is a risk of
irreversible damage to the exchanger!!
9.6. Draining and inspection of the condensate collection tank (not included
in delivery)
If the condensate is drained into a sufficiently large and accessible tank, make sure it is inspected
regularly and timely drained.
Make sure the tank is easily accessible; keep it clean!
9.7. Other minor maintenance
When replacing the air filters also check the following:
o
Cleanliness of the condensate drain. A blocked drain might cause serious problems.
o
Condensate drain flooding.
o
Door seal condition.
Regularly check the level of measurement liquid in the manometers, if necessary adjust the zero
value using the bottom knob (marked with - +). Before adjusting to zero make sure that no
pressure enters the manometer by disconnecting both hoses located on the top of the appliance.
Also regularly check the condition of the sludge filter (part of the heating / cooling system) on the
inlet of heating / cooling water into the hot water heater / water chiller.
Keep the heating/cooling system including the heater / chiller and the control set bled of air. Check
pressure in the heating / cooling system.
