10 - CONNECTIONS
When following these steps, please consult the dimensional drawing and connection diagram as well as the wiring diagram found
inside the vertical unit.
10.1 - Hydraulic connection
The hydraulic pipes must be routed through the plates provided for this purpose in the vertical unit frame. This is either done to
the right of the unit or directly underneath.
These plates must be drilled (water circuit + condensate draining) then refitted in place before the hydraulic pipes are routed through
them.
For the CW115 model, the pipes on the right are routed through a fixed insulated panel.
please see the dimensional drawing and connection diagram to locate the routing areas and connection positions.

Always use two spanners when connecting or tightening the hydraulic couplings to avoid twisting the pipes and applying stress on
the welds.
To avoid the risk of condensation, the hydraulic pipes and elements must be carefully insulated.
Before insulating, check the tightness of the couplings.
Warning: the operating pressure on the chilled or hot water network must not exceed 8 bar.
Once all the connections have been made, the access holes must be sealed.
Insulated flexible connections are available on request for carrying out hydraulic connections. Ensure these are not bent too acutely
to avoid pinching the inner tube and restricting the flow of water.
Condensate drain
The condensate drain pan should include a siphon to avoid any risk of overflowing. (See position and connection diameter on the
dimensional drawing).
In these vertical units, the pan is depressed due to its position in relation to the fan motor assembly.
To enable correct drainage, the height must be equal to at least twice the unit's depression.
