Note: Machine must not be used on any other gas than originally specified. Utile Engineering must be consulted if
traces of any other gas are introduced into the machine.

Packaging

The packaging conforms to the relevant regulations. The symbols used on the
packages are shown on the right.
The machines are bolted down on a pallet and therefore should not move during
transportation and either cased or shrink wrapped for general protection. The
ancillary components are packed suitably within the case. The packaging and
contents should be received in good condition. When unpacking do not remove
the inlet/outlet protection covers.
The contents should be inspected against the advice note, notify Utile Engineering
within 3 days of any items, which are damaged or are missing, followed by a
written claim within seven days of the goods being delivered.

Storage

If the machine is not required for immediate installation, the machine should be stored in a clean, dry area
protected from the weather. The intake and discharge port covers must remain in position until the machine is
installed. We recommend that the shaft be turned a few revolutions by hand to ensure the machine is running free
every month until the machine is installed.
The green protective coating on the shaft remains effective for approximately 1 year. If the machine is stored for a
longer period of time, the coat must be renewed.
