Condensate drain
NOTE
Backflowing condensate may damage the electronics in the switch cabinet
Internal temperatures below the dew point or defective switch cabinet seals lead to excessive condensation.
➢ Frequent checking of the seals helps to prevent heavy condensation build-up.
➢ Assemble the condensate drain hose without kinks and do not reduce the hose cross-section.
➢ Only lay the condensate drain hose on a gradient.
CAUTION
Danger of slipping due to incorrectly connected condensate drain
Condensate that drains off freely or improperly forms puddles of water that can pose a danger of slipping.
➢ Collect any condensate in a condensate collection bottle.
➢ Use condensate drain hose and regularly check connections for leaks.
Assembling condensate drain
Requirements
-
Air/water heat exchanger is mounted and without voltage.
-
Cooling water connections are assembled.
Required tools and materials
-
Assembly tool, condensate drain hose, hose clamp
Procedure
▪
Fit the condensate drain hose onto the pipe end (1) protruding from the unit.
▪
Secure condensate drain hose with hose clamp.
▪
Attach condensate drain bottle, see ordering of accessories.
▪
Check all connections for leaks.
Condensate drain is mounted.
Avoid excessive condensation:
• Adjust the cooling water temperature to the required cooling capacity.
• Only use the unit on leak-proof switch cabinets and housings.
• Set the target temperature as low as necessary, but avoid falling below the dew point.
