components containing
refrigerant are installed in
such a way as to minimise
the risk of exposure to
corrosive substances, or are
made of corrosion-proof
materials, or provided with
adequate corrosion
protection.
Checking and repairing
electrical components
The following safety measures
must be taken when repairing
and maintaining electrical
components. Do not supply the
system with voltage until any
faults that compromise safety
have been rectified. Find a
temporary solution if the system
cannot be stopped and there are
faults that cannot be rectified
immediately. Notify the system
owner of any such temporary
solutions.
Safety checks before starting
should include checking that:
• The condensers are
discharged (discharge with
safe, non-sparking method).
• No live parts or wires are
exposed during filling,
emptying or spooling of the
system.
• The earthing is intact.
Repair of sealed components
1. Disconnect the power supply
to sealed components before
they are opened.
If the work requires the
power to remain on there
must be a leakage detection
system at the most critical
points to trigger an alarm
immediately if risk situation
occurs.
2. Take care when working
with electrical components
not to damage the casings
and grommets etc. in order
to maintain the enclosure
rating.
• Pay attention to damaged
cables, terminals the deviate
from the original version,
damaged seals and
grommets etc.
• Check that electrical
components are firmly in
place and correctly
connected.
