Panasonic S-22KA1E5S Service Manual page 89

The appliance must be installed by technician, who takes into account the requirements given by ISO 5149 or eventual equivalent
requirements.
As to installation, request the distributor or vendor to perform it. Imperfection in installation caused by that having been carried out by the
customer himself may leads to water leakage, electric shock, fire, etc.
Carry out the installation work with reliability according to this manual for installation work.
Imperfection in installation lead to water leakage, electric shock, fire, etc.
Carry out the installation work with reliability on the place that can bear the weight of this unit sufficiently. Insufficient strength leads to
injury due to falling of the unit.
Carry out predetermined installation work in preparation for strong wind such as typhoon, earthquake. Imperfection in installation work
may lead to accidents arisen from overturn, etc.
The unit must be installed in accordance with applicable national and local regulations.
Any electrical work should only be carried out by qualified technician and use exclusive circuits without fail.
Presence of insufficient capacity in power circuit or imperfection in execution leads to electric shock, fire, etc.
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.
If installing inside a small room, measures should be taken to prevent refrigerant levels from building up to critical concentrations in the
event of a refrigerant leak occurring. Please discuss with the place of purchase for advice on what measures may be necessary to
prevent critical concentrations being exceeded. If the refrigerant leaks and reaches critical concentration levels, there is the danger that
death from suffocation may result.
Securely attach the protective covers for the outdoor unit connection cables and power cord so that they do not lift up after installation. If
the covers are not properly attached and installed, the terminal connections may overheat, and fire or electric shock may result.
Switch off all supplies before accessing any electrical part.
If refrigerant gas escapes during installation, ventilate the affected area. If the refrigerant gas comes into contact with sparks or naked
flames, it will cause toxic gases to be generated.
Improper fixing of screw may cause leakage current and electrical shock.
Must not use other parts except original optional parts described in catalog and manual.
Once installation work is completed, check that there are no refrigerant gas in the room that can come into contact with sparks or flames
from a fan heater, stove or kitchen range, which will cause toxic gases to be generated.
When performing piping work do not mix air except for specified refrigerant (R410A) in refrigeration cycle. It causes capacity down, and
risk of explosion and injury due to high tension inside the refrigerant cycle.
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.
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.
■ For this equipment, pump-down should not be performed.
It causes the compressor to break down.
■ During installation, ensure that the refrigerant piping is installed before operating the compressor.
Warning
(Do not install the refrigerant piping while the compressor is operating with the 2-way valve and 3-way valve opened, as
this leads to air intake and an abnormal high pressure in the refrigerant cycle which may cause an explosion and/or injury).
