Checking The Earthing Connection - Immergas AUDAX PRO 5 Instruction And Recommendation Booklet

CHECKING THE EARTH-
ING CONNECTION
Create a legally compliant earthing connection
if the building does not have one or the one it
has is not compliant. Whatever is needed to
earth the electrical system is not included in the
Immergas supply.
1 Get an earthing rod with the features shown in
figure 6-1.
2 Connect the hose to the corresponding cou-
pling.
- Moist, compact ground is preferable to sandy
or gravelly terrain, as the latter has a greater
electrical resistance.
- The earthing rod must be put in far from
the mains or underground water or gas
distribution structures, telephone networks
or underground cables
- The earthing rod must be put in at least two
metres away from connection cables and
lightning rods.
- N.B.: the unit's earthing connection must not
be made on telephone line earth connection
cables.
3 Completely wrap the connection lines to the
outdoor unit with electrical tape.
4 Connect a yellow/green cable to the earthing
rod:
- If necessary, the cable can be extended,
welding it to an extension cord and carefully
taping the junction (which, in any case, must
never be buried).
- Fasten the cable securely with hooks and clips
- N.B.: the heavier the traffic in the area where
the cable runs, the more securely fastened it
must be.
5 Check earthing connection efficiency using a
tester. If the resistance exceeds the necessary
value, you must push the earthing rod further
into the ground or add other earthing rods.
6 Connect the cable to the outdoor unit earthing
terminal.
