10.4.1. Accessories packed in the indoor unit container
10.4.2. Selecting the location for 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 according to the height from the ceiling shown in the illustration below.
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.
Wiring shall be connected 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 lead 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 gas leakage should arise and the
gas builds up around the unit, such situation may lead to ignition.
Position the indoor unit and 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.
