TIPS FOR SAVING ENERGY IMPORTANT SAFETY INSTRUCTIONS
Here are some tips that will help you minimize power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions below:
- Do not cool excessively indoors. This may be harmful for your health and may consume more electricity.
- Block sunlight with blinds or curtains while you are operating the air conditioner.
- Keep doors or windows closed tightly while you are operating the air conditioner.
- Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly. - Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.
- Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

INSTALLATION INSTRUCTIONS
Installation
1 Please fasten the back plate securely to the wall using the provided screws. Please ensure to not band the back plate as this could cause issues with installation.

2 There are three different wiring configurations. ①Through the surface of the wall ②Upper section of Remote Controller ③Right section of Remote Controller


3 Please secure remote controller upper part into the backplate attached to the surface of the wall, as pictured below, and then, connect with backplate by pressing lower part. Please make sure to leave no gaps on the top, bottom, left or right sides between the remote controller and backplate. Before assembly with the backplate, arrange the Cable not to interfere with circuit parts. Remove remote controller by inserting a screwdriver into the lower separating holes and twisting to release the controller from backplate. There are two separating holes. Please individually separate one at a time. Please be careful not to damage the inside components when separating.

CAUTION
When installing the wired remote controller do not bury it in the wall. (It can cause damage in the temperature sensor.) Do not exceed 164ft(50m) for cable length. (It can cause communication error.) Specification of LG supplied extension cable : AWG 24, 3 conductor or above. (Model : PZCWRC1)
Remote controller installation
Since the room temperature sensor is in the remote controller, the remote controller box should be installed in a place away from direct sunlight, high humidity and direct supply of cold air to maintain proper space temperature. Install the remote controller about 5ft/1.5mt above the floor in an area with good air circulation at an average temperature. Do not install the remote controller where it can be affected by:
Drafts, or dead spots behind doors and in corners
Hot or cold air from ducts.
Radiant heat from sun or appliances.
- Concealed pipes and chimneys
- Uncontrolled areas such as an outside wall behind the remote controller.
This remote controller is equipped with LCD display. For proper display of the remote controller LCD's, the remote controller should be installed properly as shown in Fig.1. (The standard height is 4\~5 ft (1.2\~1.5 m) from floor level.)
