VII. Maintenance
Kooltronic Air-Cooled Heat Exchangers are designed to require only routine cleaning of air filters and the heat
exchanger element to assure unimpeded air flow. Since the level and nature of airborne particulate matter
differs with each installation, it is difficult to recommend specific filter cleaning intervals. However, it is generally
sufficient to remove and wash the reusable aluminum mesh air filter when the outer surface of these filters
appears covered with a thin layer of dust or lint. Filter recoating adhesive, (
Part No. A-16
), available from
Kooltronic, is recommended. Replacement aluminum mesh filters are also available from Kooltronic.
If filter service is neglected or delayed, the heat exchanger will not perform at its design capacity. The first
indication of an excessively clogged air filter is a gradual increase of temperature within the equipment cabinet.
Continued operation under these conditions may cause damage, shorten blower motor life and void the warranty.
Heat Exchanger Element Cleaning
1.
Loosen and remove the (2) Torx screws on the top of the ambient impeller box.
2.
Move the ambient impeller box up and toward you and remove it from the front panel.
3.
Disconnect the plug of the ambient impeller.
4.
Remove the ambient impeller box from the unit.
5.
Depending upon the amount of buildup, the heat exchanger can be cleaned by
compressed air or by water from the top to the bottom.
6.
Reinstall the ambient impeller box:
a) Plug in the ambient impeller connector.
b) Install the ambient impeller box into the unit.
c) Tighten the ambient impeller box to the unit with (2) Torx screws.
