Frequently Asked Questions - DF-AF1833C Cotech

How do I fill the water reservoir?

Unlock the water reservoir, pull out the drawer, and fill with cold water and ice or freezer blocks up to the maximum water level mark. Do not overfill. Slide the drawer back in and lock it.

How do I clean the filters?

Press the spring catches on the dust filter (A) to remove it, then remove the water filter (B). Vacuum the dust filter. Soak the water filter in warm soapy water, rinse, and refit in reverse order.

How do I set the timer?

Press the TIMER button on the control panel or remote repeatedly to select 1, 2, 4, or 8 hours. The air cooler will automatically turn off after the set time.

What is Nature mode?

In Nature mode, the fan speed varies according to a fixed pattern based on the selected speed, alternating between off, low, medium, and high to simulate natural breezes.

What is Sleep mode?

Sleep mode follows the same pattern as Nature mode but reduces the speed at 30-minute intervals. For example, starting at high, it drops to medium after 30 min, then to low after another 30 min.

How do I use the remote control?

Insert a CR2032 battery with the positive (+) side facing up. Point the remote at the IR receiver on the unit. Buttons correspond to those on the control panel.

Why does the unit beep continuously?

A continuous beep for 10 seconds indicates low water level. Refill the water reservoir. If the button sound is annoying, you can disable it by holding the horizontal and vertical louvre buttons simultaneously for 3 seconds.

How do I disable the button sound?

Hold the horizontal louvre (UP/DOWN) and vertical louvre oscillation (LEFT/RIGHT) buttons simultaneously for 3 seconds. Repeat to re-enable.

What happens after a power cut?

The air cooler automatically goes to standby mode when power returns. Press the ON button to resume operation.

Can I use the cooler outdoors?
