Panasonic CU-J50DBE8 Service Manual page 49

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 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.
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.
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.
Mounting of the earth leakage circuit breaker is required. Omission
in mounting of the earth leakage circuit breaker may lead to electric
shock.

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 keep 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. The installation position must be able to support a load four times the indoor unit weight.
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. The indoor unit must allow easy connection to the outdoor unit.
8. The indoor unit must be 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.
Appearance Purpose
For fastening the heat
insulator
To protect the end surface
of the piping holes
Warnings
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.
Cautions
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
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.)
