Frequently Asked Questions - PAC18J Climachill

How do I install the Climachill PAC18J portable air conditioner?

Installation requires a window kit (included). Attach the exhaust hose to the unit and the window kit, then close the window onto the kit. Ensure the hose is straight and not kinked for proper airflow.

What do the error codes on the display mean?

Common codes: E1 - room temperature sensor failure, E2 - evaporator coil sensor failure, E3 - condenser coil sensor failure, E4 - display board communication error. Refer to the manual for full list.

How often should I clean the air filter?

Clean the washable electrostatic filter every 2 weeks under normal use. A dirty filter reduces cooling efficiency and may cause frost buildup.

Why is the unit not cooling or blowing warm air?

Check if the filter is dirty, the exhaust hose is blocked or not connected properly, the door/window is open, or the set temperature is higher than room. Also ensure the unit is not in Fan mode.

Does the PAC18J need to be drained manually?

In most conditions it is self-evaporating. However, in very high humidity, water may accumulate and require manual drainage via the bottom drain plug. Check the water level indicator.

Can I use an extension cord?

It is not recommended. Plug directly into a grounded 115V outlet. Using an extension cord may cause voltage drop, overheating, or fire risk.

How to program the timer?

Press the TIMER button on the remote or control panel. Use +/- to set the desired off time. Timer can be set from 0 to 24 hours. Confirm with SET button.

What is the noise level of this model?

Noise level is approximately 52 dB on low speed and 56 dB on high speed. It is comparable to a normal conversation or background music.

How to switch between Celsius and Fahrenheit?

With the unit off, press and hold the MODE button for 3 seconds until the display toggles between °C and °F.

Where can I find replacement parts like the remote or filter?

Contact Climachill customer service or visit the official website. Common spare parts include the remote control (model RC-18), air filter, and drainage hose. Check the manual for part numbers.

Venting the Exhaust Air

The exhaust hose should be kept as short and straight as possible so as to not restrict airflow of the exhausted air.

There are 3 x options with venting the exhaust air,

1) You can make a hole in the wall and pass the exhaust hose through the hole in the wall (this option doesn't require a window to be slightly open)
2) You can pass the end of the exhaust hose out of a slightly open window (you can pass the funnel attachment out of the window and then close the window onto the attachment to hold it in place
3) You can use the sliding window kit if you have an up/down or a side opening window

Window Kit Installation

The window kit is designed to fit into most standard vertical and horizontal windows. However, it may be necessary to modify some aspects of the installation process for certain window types.

1. Open the window or sliding door and adjust the length of the window kit to fit the opening. Mark and cut down a single panel of the window kit if necessary.
2. Place the window kit between the window and the window frame as shown in the images to the right. Close the window onto the window kit to form a tight seal.
3. Attach the exhaust duct adapter to the window kit. Tabs located on the adapter will lock into place securing the adapter to the window kit.

OPERATION

Before Use

• Check that the Exhaust Hose has been mounted properly (see 'Installation' section). If the exhaust Hose is not correctly used, hot air will blow back into the room you are trying cool
• Check that the drain plug at the bottom rear of the unit is securely plugged in, to prevent water leaks (see page 9 – Water Drainage)
• Check that the local mains power matches that shown on the rating label of the unit
• Check that the location of the unit is suitable (flat, stable surface; away from sources water / heat)
• If the unit has recently been transported, let it stand for 6 hours to allow the compress contents to settle

Press the SLEEP key again can cancel the setting.

WATER DRAINAGE

When the unit is in cooling mode, unwanted water is extracted from the air. Most of this water is re-used to cool the unit and make it run more efficiently. When the unit is used in extremely humid environments, water will collect in a water container at the bottom of the unit. When the water container is full, the compressor will stop but the fan will continue to run.

When the water container is full, the unit will display 'FULL' by means of the Water Indicator Full lamp being illuminated on the control panel until the tank is emptied. To resume operation, empty the water container according to the following steps:

1. Turn the unit off. Try not move the unit when the water container is full (can cause spillage)
2. Place a drain pan under the drainage port at the back of the unit (perhaps use a shallow tray)
3. Remove the rubber plug from the drain hole & drain water
4. Once the water container has been emptied, replace the rubber plug into the drain hole firmly

NOTE: In heating mode, the unit will also create water which needs emptying from the machine.

Continuous Drainage

You can of course set the unit up for continuous drainage thus negating the need to empty water from the machine. To do this remove the rubber bung from the unit and attach the drain hose to the unit, then drain the water into a container (be careful that it doesn't overspill from the container)

How to use two drainage tubes

While in Cooling & Dehumidify mode there is no need to drain water from the machine if the ambient humidity is not high as the machine will automatically evaporate the water, if ambient humidity is high then it may be necessary to drain the machine.

Draining in Cooling & Dehumidifying Mode

To Drain the machine in Cooling & Dehumidifying Mode please remove the drain plug in the middle back of the machine and attach the drain hose to have a gravity drain, this way the water full lamp will not appear.

Draining in Heating / Cooling & Dehumidifying Mode

To Drain the machine in Heating / Cooling & Dehumidifying Mode please remove the drain plug in the bottom back of the machine and attach the drain hose to have a gravity drain, this way the water full lamp will not appear.

When the water full lamp lights up, please remove the drain plug in the bottom back of the machine and attach the drain hose to have a gravity drain, this way the water full lamp will not appear.

You can drain from both outlets at the same time if you wish, doing this then water created from cooling/dehumidify mode will drain from the top outlet and water from heating mode will drain from the bottom outlet.
