We would recommend automatically terminating cooling operation, possibly with a shut-off valve, if the alarm contact is
triggered to prevent the condensation tray from overflowing.
Condensate drain
Drainage of condensation from the condensation pump has to be provided along a natural gradient with an adequate
cross-section (minimum 1/2"). Increase the cross-section of the line with longer condensation lines.
Check whether the condensation line needs to be insulated to prevent the build-up of condensation along the line.
Do not use a rigid transition to the on-site condensation drain, as this lengthens the pump's pressure hose. We would re-
commend free overflow into a trap.
Installation, cabling of the condensation pump (accessory)
The condensation pump needs a separate power supply 230 V/50 Hz. We would generally advise against connecting it via the
room thermostat, as residual condensation could be produced after it has been switched off. Additional wires are needed to
analyse the alarm contact.
Use the following types of cable:
Mains supply: NYM-J, 1.5 mm²
Alarm contact: The cable for the alarm contact depends on the kind of alarm analysis used (e.g. shielded cable).
Connecting the Condensate Pump
Push the suction hose as far as it will go and fix in place with a cable tie to prevent the pump from running dry.
