Decommissioning & Safety
the solar system can operate at extremely high temperatures. Please do not attempt
to decommission the system yourself, as there is a risk of serious injury.
there is also a risk of electrocution from 240VAc electricity.
1. Always wear appropriate Personal Protective
Equipment such as gloves and eye protection.
2. Even if the pipework near the cylinder seems cool,
the panels can be at high temperature. Decommis-
sioning should therefore only be attempted when
there is no solar input, or the panels should be
covered with light proof covers and left for at least
5 hours.
3. Turn off the switched fused spur and remove the
fuse. Leave the fuse holder open and use a padlock
or similar to lock it open. Leave a conspicuous sign
stating the power should not be reconnected.
4. Connect a short length of hose to the drain point
situated at the lowest point of the system and place
in a suitably sized container – do not drain into the
public sewerage system. Antifreeze liquid must be
disposed of correctly.
5. Open the check valve.
6. Slowly open the drain tap. When the initial flow
created by pressure has stopped, open the air-vent
at the top of the solar panels.
7. When the fluid has finished draining, disconnect
the pipework starting at the upper part of the
system. Caution – there may still be fluid in the
pipework.
8. Dispose of any materials correctly.
9. Panels should only be removed by qualified
professionals using appropriate access and safety
equipment.
The law requires employers to appoint one or more competent persons to assist them in identifying and implementing the preventive and protective measures
required.
