Earth
This equipment must be properly earthed.
Earth line must not be connected to gas pipe, water pipe, lightning rod and telephone.
Otherwise, it may cause electrical shock in case the equipment breakdown or has leakage current.
Installation of Earth Leakage Current Breaker
This equipment must be installed with earth leakage current breaker.
Otherwise, it may cause electrical shock and fire in case the equipment breakdown or has leakage current.
When installing the product, take the necessary measures for typhoon, strong wind such as wind blowing between buildings and
earthquake.
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.
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.
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 problems 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.)
When fixing the product with an overturn prevention wire, care should be taken to choose a place where no one trips over the fixing wire.

10.2.2. Before Installation Work
• This product is using new refrigeration (R410A). The basic way of installation work is the same as usual, but water and impurities
should be controlled more strictly than before due to characteristic of refrigerating machine oil. Therefore, selection of materials
to use and processing, storing and brazing need appropriate construction and control.
1. Tools and materials.
There are tools and materials for both new refrigeration and usual refrigeration you can use together and for either two of
them you can use. Use the below for new refrigeration.
• Vacuum pump (with back flow preventor system)
• Gas leakage detection warning device
• Gauge manifold
• Charge hose
