Frequently Asked Questions - PAC18H Climachill

How do I clean the air filter on my Climachill PAC18H?

Turn off and unplug the unit. Remove the filter cover located on the back panel, slide out the filter, and wash it with warm water and mild soap. Allow it to dry completely before reinstalling. Clean the filter every two weeks for optimal performance.

Why is my PAC18H not cooling properly?

Check if the air filter is dirty (clean it if needed). Ensure the exhaust hose is properly connected and not kinked. Verify that the window kit is sealed correctly. Also check that the unit is not in Fan mode instead of Cool mode. The set temperature should be lower than the room temperature.

Does the Climachill PAC18H require a bucket for water drainage?

No, the PAC18H features self-evaporation technology. It automatically evaporates condensation, so you don't need to empty a water bucket unless humidity is extremely high. In such cases, a drain hose can be attached.

Can I use the PAC18H in a room without a window?

The unit requires a window for venting the hot exhaust air. The included window kit fits vertical or horizontal windows. It can also be vented through a sliding door or a wall hole with an optional kit (not included).

What is the recommended room size for the PAC18H?

The PAC18H is designed to cool rooms up to 450 square feet, ideal for living rooms, large bedrooms, or open-plan areas.

How do I set the timer on the remote control?

Press the Timer button on the remote. Use the +/- buttons to set the desired hours (1-24). Press Timer again to confirm. The unit will turn on or off after the set time, depending on the current state.

Why does my PAC18H make a loud noise?

A rattling sound may indicate loose panels or debris in the fan. Check that the unit is level on the floor. A hissing or gurgling noise is normal due to refrigerant flow. If the noise persists, contact support.

What does the 'AA' error code mean on my PAC18H?

The 'AA' code is a self-cleaning function indicator. It runs automatically after shutdown to dry the unit and prevent mold. Wait for it to complete (about 10 minutes). This is not a fault.

How do I use the dehumidifier mode?

Press the Mode button until the 'Dry' indicator appears. The fan will run on low speed. No exhaust hose is needed in this mode, but water will accumulate in the internal tank and may need manual draining via the drain plug.

What is the warranty for the Climachill PAC18H?

The PAC18H comes with a 1-year warranty covering parts and labor. For warranty claims, contact Climachill customer service with your proof of purchase.

INSTALLATION

Exhausting the Air

It is necessary to use the exhaust hose when using the machine. When in Cooling Mode hot air will be expelled out of the exhaust hose When in Heating Mode cold air will be expelled out of the exhaust hose

Setting Up the Exhaust Hose

Take the 3x components, extend the exhaust hose and then twist the accessories onto each end of the hose

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

Cooling Mode

Press the "Mode" button till the "Cool Mode" icon appears.

Press the “▲” or “▼” button to select a desired room temperature. (16 ℃ - 31 ℃)

Press the "Fan Speed" button to select wind speed.

NOTE: During hot days, the unit will cool off the room most efficiently by setting the temperature at the lowest and the fan speed at the highest. Reducing the length of the exhaust hoses, insulating the exhaust hoses, and keeping direct sunlight to a minimum will also improve the cooling efficiency.

Heating Mode

Press the "Mode" button till the "Heat Mode" icon appears.

Press the “▲” or “▼” button to select a desired room temperature. (16 ℃ - 31 ℃)

Press the "Fan Speed" button to select wind speed.

Dry (De-humidifying) Mode

Press the "Mode" button till the "Dry Mode" icon blinks

Set the selected temperature to current room temperature minus 2°C. (16°C - 31°C)

Set the fan motor to LOW wind speed.

AUTO Mode

According to the current room temperature the unit will automatically select the mode - cooling, dehumidifying or heating.

When the room temperature is <23 °C the unit will enter Heat Mode

When the room temperature is 23C - 26C the unit will enter Dry Mode

When the room temperature is ≥slant26^ the unit will enter Cooling Mode

Timer Mode

Timer ON setting

When the air-conditioner is OFF, press the "Timer" button and select a desired ON time through the temperature and time setting buttons.

"Preset ON Time" is displayed on the operation panel.

ON time can be regulated at any time in 0-24 hours.

Timer OFF setting

When the air-conditioner ON, press "Timer" button and select a desired OFF time through the temperature and time setting buttons.

"Preset OFF Time" is displayed on the operation panel.

OFF time can be regulated at any time in 0-24 hours.

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 'E2/E4' 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)

Recommendation

To make it easier to empty the water from the machine we recommend raising the unit from the floor, this will allow easier access to the drain port and allow easier drainage. We aim to sell a floor mount for the unit which will allow you to place the unit into the floor mount which will raise the height of the unit and thus raise the height of the drain port – please see www.climachill.co.uk for details.

MAINTENANCE & CLEANING

1) Before cleaning, be sure to disconnect the unit from any electric supply outlet;
2) Do not use gasoline or other chemicals to clean the unit;
3) Do not wash the unit directly;
4) If the conditioner is damaged, please contact the dealer or repair shop.
