Dimension of pressure connection nipples
• Install first the pressure connection nipples (included in the scope of supply) onto the duct.
Use a Ø 7.5 mm drill.
• Connect the pressure hose (included in the scope of supply) first to the EE610 and then to the nipples
at the duct. Route the pressure hose for avoiding sharp bends which might lead to the hose
obstruction („Fig. 9 Pressure hose route“).

Pressure hose route
Important: Make sure to connect the higher pressure at the “+” pressure connector and the lower
pressure at the “-“ pressure connector. Inverted connection leads to “out of range” information on the
optional display and at the analogue outputs, see „4.1.6 Outputs“ and „7.2.3 Out of range“.
