To facilitate maintenance and to allow access to the various components, we recommend that you provide sufficient space all around the hydraulic module. Be careful not to bring inflammable gas near to the heat pump during its installation, in particular when it requires brazing. The appliances are not fireproof and should not therefore be installed in a potentially explosive atmosphere. - (IU01-06) - Indoor unit / 3 phase
