Electrical Wiring - Panasonic CS-F14DB4E5 Service Manual

2. Precautions in high humidity circumstance.
This air conditioner has been tested according to the "JIS Standard Conditions with Mist" and have been confirmed that there
are no faults. However, if it is operated for a long time in high humid atmosphere (dew point temperature: more than 23°C),
water drops are liable to fall. In this case, add heat insulation material according to the following procedure:
• Heat insulation material to be prepared... Adiabatic glass wool with thickness 10 to 20 mm.
• Stick glass wool on all air conditioners that are located in ceiling atmosphere.
• In addition to the normal heat insulation (thickness: more than 8 mm) for refrigerant piping (gas piping: thick piping) and drain
piping, add a further of 10 mm to 30 mm thickness material.
Wall seal
• When the outdoor unit is installed on a higher position than the indoor unit, install the trap so as not to instill rain water into the
wall by transmitting in piping.
• Stuff the space among piping, the electric wire, and the drain hose with "Putty" and seal the penetration wall hole.
Make sure that rain water do not instill into the wall.

10.4.7. Electrical wiring

As to the main power source and cable size of outdoor unit, read the installation manual attached to the outdoor unit.
The units must be installed in accordance with applicable national and local regulations.
The units installed by a professional installer must be supplied from a dedicated electrical circuit.
All electric work must be carried out by a qualified technician according to proper technical standards for electrical work and
according to installation manual for installation work.
If circuits with insufficient capacity are used, or if electrical work is not carried out properly, electric shocks or fire may result.
Warning
Be sure to install a current leakage breaker or circuit breaker to the main power supply, otherwise electric shocks may result.
Be sure to connect the unit to secure earth connection. (with an earth resistance of 100Ω or less)
If the earthing work is not carried out properly, electric shock may result.
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.
1. Select a power source that is capable of supplying the current required by the air conditioner.
2. Feed the power source to the unit via a distribution switch board designed for this purpose, the switch should disconnected all
poles with a contact separation of at least 3 mm.
3. Always ground the air conditioner with a grounding wire and screw to meet the LOCAL REGULATIONS.
4. Be sure to connect the wires correctly to terminal board with connecting the crimp tyre ring terminal to the wires.
5. Be sure to turn off the main power before installing and connecting the remote controller.
If momentarily turning on the power supply for both the indoor and outdoor units, do not turn the power off after at least 1 minute
has passed. (for the system's automatic setting.)
Note
Turning off the power supply on the way may cause an abnormal operation.
• Use the standard power cord for Europe (such as HO5RN-F or HO7RN-F which conforms to CENELEC (HAR) rating specifica-
tions) or use the cable based on IEC standard. (245IEC57, 245IEC66)
