R410A is a fluorinatedgreenhouse gas covered by the Kyoto Pro-tocol, with a GWP of 1725 (GWP = GlobalWarming Potential). If it escapes into the at-mosphere, its impact is 1725 times strongerthan the natural greenhouse gas CO2.Before the heat pump is disposed of, thecoolant it contains must be completelydrained into a suitable vessel so that itcan then be recycled or disposed of inaccordance with the regulations.▶ Ensure that only officially certified com-petent persons with appropriate protectiveequipment carry out maintenance work onthe coolant circuit or access it.▶ Arrange for the coolant contained in theproduct to be recycled or disposed of byaccredited specialists in accordance withregulations.▶ Only use coolant R410A.▶ Only use a suitable R410A tool for thefilling, pressure measurement, vacuumgeneration and discharge.▶ Solder the lines using shielding gas. Checkthe lines for leak-tightness using nitrogen.▶ In the event of a repair or maintenancework, fill the coolant circuit with liquidcoolant.▶ If the coolant circuit is not leak-tight, checkwhich component must be repaired or re-placed.▶ Lower the negative pressure in the coolantcircuit to max. 10 mbar (1000 Pa).▶ When filling the coolant circuit, observe thevalues in the "Technical data" section.1.4 Regulations (directives, laws,standards)▶ Observe the national regulations, stand-ards, guidelines and laws.1.5 CE labelThe CE label shows that the products complywith the basic requirements of the applicabledirectives as stated on the identification plate.The declaration of conformity can be viewedat the manufacturer's site.1.6 ApprovalsThis product has been fully tested in accord-ance with:– BS EN 14511:20111.7 Local regulationsBenchmark places responsibilities on bothmanufacturers and installers.
