It is advisable to create an adequately sized support base for the unit. The units transmit a small amount of vibrations to the ground: it is none- theless advisable to apply vibration dampers between the base frame and support surface. - Page 13 Model HPE R32 40 1200 1000 1000 1500 HPE R32 1200 1000 1500 1500 50 / 60 / 70 L min In the event of side-by-side units, the minimum Lmin distance be- tween them is 2200 m. Covering with canopies or placing near plants or walls should be avoid- In the event of winds stronger then 13,9-17,1 m/s the use of wind barriers is recommended.

It is advisable to use an external tap to fill the system, which is the responsibility of the installer. There is always a service tap in the unit to be used if it is necessary to top up/ discharge the amount of water in the system or adjust the percentage of glycol. If the unit must be completely drained,first close the manual inlet and outlet shutters (not supplied) and then disconnect the pipes on the water inlet and outlet so that the liquid in the unit can drain (to make this operation easier, it is advisable to install two external drain cocks between the unit and the manual shutters on the water inlet and outlet). -
