6. Always shut the inner door
Shut the inner door completely, and then shut the outer door. If the inner door is not closed completely,
even if the outer door is closed, the unit will fail to exhibit its maximum performance. And close the
doors gently. Rude closing may cause spillage of medium, incomplete closing, or damage of gasket.
Before opening the inner door, check that the UV light is OFF.
7. Keep the inside panels dry
To protect the inside of the unit from contamination, the inside panels should always be kept dry. If
water is spilled from a humidifying pan or if the door is kept open for a long period, condensation will form
on the panels, allowing germs to breed. In such a case, wipe away the water with a dry sterile gauze.
Particularly, if the medium is spilled, wipe it up immediately and sterilize the area.
8. Fill the humidifying pan with sterile distilled water
Always use sterile distilled water to fill the pan. The RH PAN light on the control panel flashes when the
water level is low. Refill the sterile distilled water to the pan when the RH PAN light blinks. Note that
when low temperature water is poured, the chamber temperature drops significantly. Clean the pan
once a month.
