7.3 Fitting/removing the cooling module
7.3.1 Decommissioning the cooling module
Work steps: decommissioning
1 Isolate the supply voltage
2 Isolate the water inlet to the cooling module
3 Open the bleeder valve on the cooling module
4 Open the drainage valve (external) and allow the pipes to drain until empty.
5 Disconnect water connections at the cooling module.
Note: place a suitable receptacle (approx. 6 litres) underneath.
6 Close the bleeder valve on the cooling module
7 Seal the water connections on the cooling module to prevent damage to
nearby components being caused by any leakage of residual cooling water.
Attention!
Under no circumstances should the cooling module be stored and transported
in contact with water. After removal the module should be laid on its side so
that any remaining cooling water can drain from the heat exchanger.
All water connections must be closed with suitable blind plugs to prevent
damage to nearby components caused by any leakage of cooling water from
the unit.
Where temperatures during storage or transport may fall below 0° C the heat
exchanger should be flushed with an appropriate antifreeze (ethylene glycol).
Attention!
If the water connections on the cooling module are isolated the heat exchanger
remains filled with water, since the inlet and return are situated on top of the
exchanger.
Attention!
Where temperatures may fall below 0° C following decommissioning the heat
exchanger should be flushed with an appropriate antifreeze (ethylene glycol).
