3.4 Water and direct expansion coil
Do not remove the protective caps until you are ready to connect the coils.
Coil with water supply
Always use two spanners when connecting or tightening the hydraulic couplings to avoid twisting the pipes and applying stress on
the welds. Check the tightness of the connections before installing heat insulation or filling the system with water.
If flanges are used, provide enough clearance for the frost protection sensor drawer or the droplet separator drawer.
The flanges should be offset.
Supplying the coils
Warning: water + glycol = risk of burns and toxic if ingested
Refer to your dimensional drawing for the diameters of the connections and their positions.
Check the connections for leaks after 24 hours.
