2-5 Fixture
The unit should be placed horizontally and fixed on foundation by bolts.
2-6 Connection of Air Duct
Generally, YCM air handling unit should be connected by supply air duct and return air duct (You don’t need to
connect return air duct if return air were connected by corridor). The arrangement and direction of supply air duct should
meet the specification and standard. In order to prevent acoustic noise regeneration when vibration is transmitted to air
duct, air duct should be connected with the unit by one 100~200mm length flexible duct. Such connection should be
good airproof and without any air leakage. The air duct itself should not be supported on the unit. It should be supported
by brace or hanger. Air duct should be equipped with good insulation to avoid condensation.
2-7 Connection of Water Pipe
Inlet/outlet pipe are connected with pipeline by screw connection. You should use two pipe pinchers (see Diagram 3).
Please take carefully so as not to damage screw and cause leakage. Pay attention to the flow direction of water in pipe
when connect them. Do not reverse them.
