Operating Instructions
Before getting started, please remove the
Clean Air Optima CA-604
from its box and allow it to
become accustomed to the room temperature for at least 30 minutes especially if the machine is
cold from the outside air. The CA-604 is designed to operate at temperatures between 5 -40 ºC
and relative humidity of less than 80%.
To get started, grasp the water tank by the handle at the top and lift from the base. Next, flip the
tank over and unscrew and remove the water tank lid and filter.
Then place the water tank under the faucet for filling, grasping it from the handle under the water
tank. Fill the tank with tap water (or other clean water source with water temperature under 40ºC),
re-insert the lid and filter. Flip the water tank once again until it is on the right side up. Ensure that
the basin is clean and then carefully place the water tank back on the lower body.
Wait a few seconds until the water tank lid starts to release water into the basin. You will hear a
bubbling sound as the air enters the water tank. Plug the power cord into the electrical outlet
(NEVER SWITCH ON THE HUMIDIFIER WITHOUT WATER IN THE BASIN). If the humidifier is
switched off, the power icon (#13) should now be red and the values for temperature and humidity
will now be displayed.
