Cleaning
The most important cleaning task is to remove accumulations of dust,
lint, and grime that could interfere with proper air circulation and
therefore efficient heat transfer. The heat exchanger surfaces,
particularly on the inside, should be checked periodically for possible
collection of dust and lint. When cleaning is necessary, follow these
instructions.
1. Remove and retain the 18 screws from the edges of the top panel,
and the top panel.
2. Clean off dust and lint, if any, with a radiator brush or stiff bristle
brush. A vacuum can be used to clean the coils if necessary.
3. Check under the ribs of the exhaust grille (at the side) for dust
collection. If there is a buildup, remove the grille and clean under
the ribs.
4. Replace top panel and screws.
Heavy coatings of lint on any surfaces of the heat exchanger unit can
impair the efficiency of the Moduload unit. Keep the surfaces of the
heat exchanger clean.
Radiator Surface The radiator surface, particularly on the inside, should be checked
periodically for possible collection of dust and lint. A heavy lint
coating on the inside surface of the radiator can impair the cooling
efficiency of the unit. Follow the instructions below for cleaning.
1. Remove the 18 screws from the edges of the top panel and remove
the panel.
2. Clean off any collected dust and lint with a radiator brush or any
stiff bristle brush.
3. Replace the top panel.
Connector and
Outside
The outside surface of the unit should also be wiped free of dust and
dirt at regular intervals. Use a soft, clean cloth dampened with mild
detergent. Check the condition of the RF coaxial connector. If needed,
clean the RF input connector using a selfdrying contact cleaner that
leaves no residue on the inaccessible portions.
