Installation of Indoor, Outdoor Unit

Read completely, then follow step by step.

Indoor unit

1. Does not have any heat or steam near the unit.

2. Select a place where there are no obstacles in front of the unit.

3. Make sure that condensation drainage can be conveniently routed away.

4. Do not install near a doorway.

5. Ensure the unit is unobstructed, allow proper space on all sides according to the arrows and distance measurements in the figures.

6. Use a stud finder to locate studs to prevent unnecessary damage to the wall.

Outdoor unit

1. If an awning is built over the unit to prevent direct sunlight or rain exposure, make sure that heat radiation from the condenser is not restricted.

2. Ensure the unit is unobstructed, allow proper space on all sides according to the arrows and distance measurements in the figures.

3. Do not place animals and plants in the path of the warm air.

4. Take the air conditioner weight into account and select a place where noise and vibration are minimum.

Select a place so that the warm air and sound from the air conditioner does not disturb neighbors.

Rooftop Installations:

If the outdoor unit is installed on a roof structure, be sure to level the unit. Ensure the roof structure and anchoring method are adequate for the unit location. Consult local codes regarding rooftop mounting.

Seaside Applications and Installation

8 Wall Mounted Multi-Zone Split System Air Conditioner

Installation of Indoor, Outdoor Unit

Air conditioners should not be installed in areas where corrosive gases, such as acid or alkaline gas, are produced.

2. Do not install the product where it could be exposed to sea wind (salty wind) directly. It can result in corrosion to the product. Particularly on the condenser and evaporator fins, could cause product malfunction or inefficient performance.

If the outdoor unit is installed close to the seaside, ensure that it is not exposed directly to the sea wind.

1) If the outdoor unit is to be installed close to the seaside, direct exposure to the sea wind should be avoided. Install the outdoor unit on the opposite side of the sea wind direction.

2) To install the outdoor unit on the seaside, set up a windbreaker/barrier, to lessen the unit's exposure to sea air

3) Select a well-drained place.

• It should be strong enough (like concrete) to obstruct the wind from the sea.

• The height and width should be more than 150% of the outdoor unit.

• A minimum of 70cm (27.6inches)

of space between outdoor unit and the windbreaker/ barrier for easy air flow.

Sea wind Sea wind
