• The following table gives a list of the types of thread for each UTV.
• For heat exchangers with threaded con-
nections, secure the coil manifold with
the appropriate tool when tightening the
threads. This will prevent the force from
being transmitted to the manifold, which
can damage it.

• Never use the unit as a support or weight-bearing structure for ductwork.
• Connect the unit to the air ducts using flexible connectors to prevent vibrations from
being transmitted to the duct system.
• Check to make sure air intake and flow are not being blocked and that there are no
obstacles impeding good air circulation. Failure to do so will affect the efficiency of the
system.
VERY IMPORTANT:
In the manufacturing process of the panels, fi lters and batteries, protective products
are used to increase corrosion protection. During the fi rst hours of operation after the
unit commissioning, especially in those units equipped with heating stage, unplea-
sant smells could be produced.
