Instruction
11.1 Indoor Unit
11.1.1 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.
3 Mount with the lowest moving parts at least 8 ft (2.4 m) above floor or grade level.
* If the height from the floor to ceiling exceeds three meters, air flow distribution deteriorates and the effect is
decreased.
4 The installation position must be able to support a load four times the indoor unit weight.
5 The indoor unit must be away from heat and steam sources, but avoid installing it near an entrance.
6 The indoor unit must allow easy draining.
7 The indoor unit must allow easy connection to the outdoor unit.
8 Place the indoor unit according to the height from the ceiling shown in the illustration below.
9 The indoor unit must be from at least 9.8 ft (3 m) away from any noise-generating equipment. The electrical
wiring must be shielded with a steel conduit.
10 If the power supply is subject to noise generation, add a suppressor.
11 Do not install the indoor unit in a laundry. Electric shocks may result.
Note
Thoroughly study the following installation locations
1 In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the turbo
fan, the fin of the heat exchanger and the drain pump, resulting in heat exchange reduction, spraying,
dispersing of water drops, drain pump malfunction, etc.
In these cases, take the following actions:
o
Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capacity so
that it draws oily steam which should not flow into the suction of the air conditioner.
o
Make enough distance from the cooking room to install the air conditioner in such place where it may not
suck in oily steam.
2 Avoid installing the air conditioner in such
circumstances where cutting oil mist or iron
powder exist especially in factories, etc.
3 Avoid places where inflammable gas is
generated, flows-in, contaminated, or leaked.
4 Avoid places where sulphurous acid gas or
corrosive gas can be generated.
5 Avoid places near high frequency generators.
