Cannot remove the GRI 181 filtration unit for pool liner renewal as Desjoyaux have cemented the unit to the support walls. What do you suggest I do to get round this problem?

To remove the Desjoyaux GR.I 181 filtration unit for pool liner renewal, follow these steps:

1. Build a form (e.g., using rigid cardboard) around the technical compartment during installation to allow space for removing the unit later.
2. Ensure that this formwork remains in place until the pool deck is laid.
3. When it's time to replace the liner, remove the filtration unit from the pool wall as it must be taken out before installing the liner.
4. Carefully detach the unit, avoiding damage to the liner or surrounding structures.

This process allows safe removal of the unit even if it is cemented in place, provided proper space was left during installation.
