Air Handlers Units
ClimaPac Series
Connecting the unit to the external system
Water remaining from the test run may escape when the protective caps are removed.
• Rinse thoroughly water lines of the external system to ensure water entering the water coil is clean
and free of particles.
• Remove the protective caps of the pipes inlet and outlet.
• Fix the lines of the external system to the lines of the unit. Water inlet/outlet and connection type
are indicated in the table above.
• Insulate the water pipes with the diffucion tight insulating material, to prevent the introduction of
ambient air heat and the formation of condensate at the pipes.
Make sure the external system lines don’t put mechanical stress on the ClimaPac
connection pipes.
Condensate drain
The condensate water drains must be provided with a siphon (see siphon calculation in
4.3.2
Connection of drains
and connected to local waste water system.
If the coil is designed to work with water, the use of an anti-freezing agent might
have an impact on the coil effi ciency.
4.3.5 Water quality
In all the components using water (water coils), and regardless of the type of treatment or added
agents that are used, the water must be perfectly clean.
Tap water can be used in the water coils, possibly adding an antifreeze agent.
For more information on the type of treatment and the quality of the water used, refer to the instruc-
tion manuals of the different components.
