All pipework and connections must be made in accordance with good refrigeration design and
installation practice.
Before performing the connection, ensure that no flammable gas is present in the system and in the
product.

attached to the walls/ceilings of the cold room and not only to the cooler itself. Pipework must be
adequately supported to prevent vibration or external load on the cooler headers, etc.
Components that may cause gas leaks (for example pressure points) must not be installed inside
the product. All refrigeration connections must be made by brazing.
Do not adapt headers position to the suction line.
Ensure the supply circuit is closed (no pressure)
before connecting the suction lines.
