IX. Maintenance
KoolTray II fantrays are designed to require only routine cleaning of optional air filters (if supplied) to assure
unimpeded air flow. It is not possible to recommend specific filter cleaning intervals since the level and the nature
of air borne particulate matter differs widely with each installation. 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 is recommended. Appropriate disposable filters are available from Kooltronic.
X. Packing Procedure For Warranty Repair
Pack the KoolTray in an appropriate carton (preferably the original carton), with adequate internal protective
packaging, making sure carton is marked properly.
