4.2.3 Connecting the water circuit connections

If there are two connection pipes, the unit can be used for cooling or heating. If there are four connection pipes, the
outer pipes are used for cooling and the inner pipes for heating.
Connect the water circuit connections according to the design drawings. You can use, for example, push-fit fittings
or compression fittings. With compression fittings, to avoid damaging the pipes, use two wrenches to tighten the
fitting.
Note: It does not matter which way you connect the supply and return water connections. The flow direction in the
coil does not affect the performance of the unit.
