delivery)
Thermoguard coils:
• are marked with inlet and outlet, respectively, on the fluid side, as well as air direction.
• delivered, as standard, for vertical assembly (horizontal air stream).
• must always have the possibility of pressure relief via the coil return line out to the expan-
sion vessel, regardless of whether the control valve is open or closed. This applies to all
kinds of control valves, shunt couplings and the like.

For duct assembly see "12 DUCT CONNECTION, DUCT ACCESSORIES”, page 39.
The cooling coil must be connected for horizontal air stream and so that the water flows
towards the air stream. The water trap must have a height of at least 100 mm (9) and be incre-
ased by 10 mm for every 100 Pa in addition to 1000 Pa.
