If An Indirect Refrigerant Circuit Is Used, The Presence - Atlantic Explorer Installations- Und Bedienungsanleitung

No work (maintenance, repairs, servicing, etc.) other than leak
detection (see procedure) is permitted on the refrigerant circuit.
Failure to follow this procedure may lead to ignition or explosion
due to the flammable fluid.
1. Checking the refrigerant equipment
When replacing electrical components, they must be suitable for
use and meet the required specifications. The manufacturer's
maintenance and servicing directives must be followed. If in doubt,
contact the technical department for help.
The following checks must be applied for installations using
flammable refrigerant fluids:
• The actual refrigerant fluid is suited to the size of the room
in which the refrigerant circuit is installed
• The ventilation system and the openings operate correctly and
are not obstructed

• If an indirect refrigerant circuit is used, the presence

of refrigerant fluid in the secondary circuit must be checked;
• The markings on the equipment must always be visible and
legible. Any markings and identifications which are illegible
must be corrected.
• The pipework and the components of the refrigerant circuit are
installed in a position where it is unlikely that they are exposed
to substances likely to corrode components containing
refrigerant fluid, unless the components are designed from
materials which are naturally resistant to corrosion or suitably
protected from such corrosion
