1 - INTRODUCTION 1.2 - Installation safety considerations Prior to the initial start-up of the Aquaciat Caléo™ TD units, the people involved should be thoroughly familiar with these After the unit has been received, when it is ready to be installed instructions and the specific project data for the installation site.
When the unit is subjected to fire, safety devices prevent rupture due to over-pressure by releasing the refrigerant. CIAT recommends the following drafting for a logbook (the table The fluid may then be decomposed into toxic residues when below should not be considered as reference and does not...
• Recommissioning of the equipment. 2. Ensure that the refrigerant is never released to Consult CIAT Service for this type of test. CIAT mentions here the atmosphere during installation, maintenance only the principle of a test without removing the pressure switch: or equipment disposal.
