Humidifying Tray Cleaning
(Not necessary for LU cabinet)
CAUTION
•
SHARP EDGES! Be careful of projections or sharp
edges inside the cabinet.
For your safety, always wear gloves when working inside the
cabinet.
•
HOT ON THE INSIDE! Cool down the test area
before cleaning the humidifying tray.
During and shortly after operation, the cabinet is HOT and humid
on the inside.
During operation, dirt and foreign matter stick to the humidifying tray and
humidifying heater. To ensure long lasting use, clean the tray and heater
of dirt once a month. A good way to inhibit dirt from accumulating is to
drain the humidifying tray after every test.
