9.2.1. Accessories packed in indoor unit container
• The following parts are supplied as accessories with each outdoor unit.
Check that all accessory parts are present before installing the outdoor unit.
9.2.2. Selecting the location for the indoor unit
Provide a check port on the piping side ceiling for repair and maintenance.
• Install the indoor unit once the following conditions are satisfied and after receiving the customer approval.
1. The indoor unit must be within a maintenance space.
2. The indoor unit must be free from any obstacles in path of the air inlet and outlet, and must allow spreading of air
throughout the room.
*If the height from the floor to ceiling exceeds three meters, air flow distribution deteriorates and the effect is decreased.
3. The installation position must be able to support a load four times the indoor unit weight. Warnings
4. The indoor unit must be away from heat and steam sources, but avoid installing it near an entrance.
5. The indoor unit must allow easy draining.
6. The indoor unit must allow easy connection to the outdoor unit.
7. Place the indoor unit easy water drainage. (Suitable dimension “H” is necessary to get slop to drain as figure.)
8. The indoor unit must be from at least 3m away from any noise-generating equipment. The electrical wiring must be
shielded with a steel conduit.
9. If the power supply is subject to noise generation, add a suppressor.
10. Do not install the indoor unit in a laundry. Electric shocks may result.
Wiring shall be connected securely using specified cables and
fix them securely so that external force of the cables may not
transfer to the terminal connection section.
Imperfect connection and fixing leads to fire, etc.
Cautions
Carry out Earthing work.
Do not connect the Earth return to the gas pipe,
water line pipe, lightning rod and telephone lines.
Imperfection in Earth return may lead to electric
shock.
Drain piping should be made to ensure secure drainage
according to the manual for installation work and carry out the
thermal insulation to prevent the occurrence of condensation.
Imperfection in piping work leads to water leakage and may
cause the house and property, etc. to become wet.
Do not install the unit at the place where the possibility of
inflammable gas leakage exists. If such gas leakages should
arise and the gas builds up around the unit, such situation may
lead to ignition.
Position the indoor unit, outdoor unit, power cords and indoor/
outdoor unit connection cables in a way so that they are at least 1
meter away from televisions and radios.
This is to avoid problem such as interference with picture and/or
sound. (However, note that depending on the electromagnetic
wave conditions, interference may still occur even if the
separation distance is more than 1 meter.)
Mounting of the earth leakage circuit breaker is required.
Omission in mounting of the earth leakage circuit breaker may
lead to electric shock.
