If objects or hail fall on the unit, there is a risk that the finned

components may be damaged. Take appropriate steps to
protect it, by adding a protective screen, for example.

If the unit needs to be installed on a framework, this

structure must be calculated based on the weight of the
unit during service (full), equipped with all its
accessories.

Check that the sound level given in the technical instructions

or in the order acknowledgement receipt is compatible with the
permissible value for the site.

Similarly, it is recommended that personnel working close to

sources of high noise emission wear soundproof headphones.
Soundproof headphones should in no way impede the wearing
of other protective equipment.

The connection pipes and the regulation or insulation

equipment must be set up and supported so as to ensure they
do not exert any force on the unit's piping (pressure, torsion or
flexion).

Ensure that the unit is perfectly level so that the pipe bundle

can drain correctly. Also ensure that the unit is stable and
secured using all of its anchorage points.

Provide shut-off valves on the inlet and outlet pipes.

The unit must be fitted with an emergency stop device,

located very nearby; this device must be visible and 

accessible and must allow the electrical supply to the unit and
its accessories to be cut off completely.

Ensure that cutting off the electrical supply, whether

intentionally or accidentally, does not jeopardise the process.

For any accessories, refer to the 

specific guides.

Install suitably effective venting and draining devices.

Connect the pipes to earth in accordance with the overall

lightning protection study for the installation as a whole.

Ensure that the installation complies with the legal texts and

codes in force in the country of operation.

Electrical connections

Electrical connections must be carried out by personnel who

are qualified in accordance with current standards and
regulations.

Ensure sufficient devices are provided to guarantee

the protection of persons and property, and to enable
maintenance operations to be carried out in complete

safety.

Choose power and control cables based on the unit's

electrical specifications and the recommendations given in the
manuals provided with the accessories.
