CAUTION

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

2. If the outdoor unit is installed close to the sea shore, direct exposure to the sea breeze

should be avoided and choose an outdoor unit with anti-corrosion treatment.

3.1 Selection procedure

Outdoor units selection

In general, an outdoor unit may be selected as follows, though the location of the unit, and usage of the room, etc. should be considered. The combination of indoor and outdoor units should be determined so that the sum of indoor unit capacity index is smaller than the max. combination capacity of the outdoor unit. Up to max.8 indoor units can be connected to one outdoor unit. It is recommended to choose a large capacity outdoor unit if the installation space is large enough.

Indoor units selection

Look up the table on combination of indoor and outdoor units, and determine the appropriate indoor unit capacity which satisfies the given thermal load. For proper system operation, refer to the following:

1) At least 2 indoor units should be connected to outdoor unit.

2) Total capacity of indoor units connected should be minimum 40% of outdoor unit above mentioned capacity.

3) Calculation method for total capacity index = sum up the capacity index of connected indoor units.

3.2 Combination of indoor and outdoor unit

The total capacity index of indoor units is the sum of capacity index of each unit and should be within the capacity index of the outdoor unit.

Note:

1. * For more capacity information, refer to the combination tables.

2. The combination of indoor and outdoor units should be determined so that the sum of indoor unit capacity index is smaller than the max. combination capacity of the outdoor unit. Refer to the combination table.

3. At least two indoor units should be connected.
