Procedure
Step 1 Use a multimeter to check the grounding of each cabinet component:


Step 2 Remove the air filter frame from the cabinet bottom. Wash and dry the filter thoroughly and
then place it back into the cabinet.
Step 3 Remove the air filter gauze from the inner side of the cabinet's front door. Dehydrate the
gauze and let it dry. Then, replace.
Step 4 Take out the air deflector from inside the jamb on the cabinet's front side. Use a piece of clean
cotton gauze, an anti-static brush, or a vacuum cleaner. Then replace.

Maintenance Guide
(1) Check the cabinet cover for
cleanliness.
(2) Check the air filter at the
cabinet bottom for cleanliness.
(3) Check the air filter gauze at
inner side of the cabinet's front
door for cleanliness.
Check labels are clearly written
and marked and securely
attached.
Set the multimeter to the resistance position and connect one lead to a fixed place in the
equipment room (you may need to extend the lead cable) and the other lead to measure
each grounding point inside the cabinet. Given the measuring accuracy, the measured
resistance of each grounding point should be approximately 1 ohm or less. If the
resistance measured at a grounding point exceeds 1 ohm, check the grounding cable,
connecting terminal and fastening screw and make appropriate corrections.
Set the multimeter to the voltage position and connect one lead to a fixed place in the
equipment room (you may need to extend the lead cable) and the other pointer to
measure each grounding point inside the cabinet. Given the measuring accuracy, the
voltage measured at each grounding point should range between 0 V and 5 V. If the
voltage measured at a grounding point is 0 V, the point is not grounded. In the case of a
value larger than 5 V, check the grounding cable, connecting terminal and fastening
screw at the grounding point and make appropriate corrections.
