CHECKING
CORRECT EARTHING.
If the electric distribution circuit is not earthed or earthing does
not comply with the specications, an earthing system must be
installed. e corresponding accessories are not supplied with
the condensing unit.
1. Select an earth electrode compliant with the specications
indicated in gure 35.
2. Connect the exible hose to the coupling.
- Preferably on a hard or moist ground rather than sandy or grav-
elly due to the greater earth resistance.
- Away from structures or underground structures, such as gas
pipes, water pipes, telephone lines or buried cables.
- At least 2 m from a lightning conductor and from its cable.
- e earth wire for the telephone line cannot be used
to earth the condensing unit.
3. Finish by wrapping electrical tape around the pipes in the di-
rection of the outdoor unit.
4. Install a green/yellow earth wire:
- If the earth wire is too short, mechanically connect an extension
cable and wrap it with electrical tape (do not bury the connec-
tion).
- Secure the earthing cable in position with appropriate anchors.
- If the earth electrode is installed in an area with heavy
trac, its wire must be connected securely.
5. Carefully check the installation by measuring the earth re-
sistance with an ohmmeter. If the resistance is higher than the
required level, plant the electrode deeper into the ground or
increase the number of earth electrodes.
6. Connect the earthing cable to the electric components box
inside the outdoor unit
