The unit’s hydraulic data are specific to your installation and are determined by the computer selection :
Water pressure drop / Waterflow. Refer to the selection to size the network, accessories, pump, etc.
The pipe connection to the coil must not impose mechanical, vibrational or thermal (expansion) stresses
on the coil.
The coils are delivered end-threaded.

When tightening the coils threads, hold the pipe in the counter direction, for example, with a Stillson type
wrench to prevent pipe damages by torsion.
The coils are connected to the network inside the unit. Respect the water inlet and outlet directions.
