Condensate drain
NOTE
Condensate flowing back into the switch cabinet can damage the electronics
Internal temperatures below the dew point or damaged switch cabinet seals cause excessive accumulation of
condensate.
➢ Regular inspection of the seals assures protection against heavy condensate accumulation.
➢ Mount condensate drain hose free of bends and don't reduce hose cross-section.
➢ Only mount the condensate drain hose with a downward gradient.
CAUTION
Danger of slipping due to improperly connected condensate drain
Condensate flowing away freely or improper condensate drains can form water puddles and present danger of
slipping.
➢ Collect accumulating condensate in a condensate collecting bottle.
➢ Use pressure-resistant (>10 bar), elastic hoses and regularly check connection seals.
Install condensate drain
Requirements
-
Air/ water heat exchanger is assembled and de-energized.
-
Cooling water connections have been installed.
Required tools and material
-
Installation tool, pressure-resistant (>10 bar) hoses, hose clamps
Procedure
▪ Attach pressure-resistant, elastic hoses (>10 bar) to the pipe end (1) projecting out of the unit.
▪ Secure condensate drain hose with hose clamps.
▪ Attach condensate drain bottle, see Ordering
▪ Check seal of all connections.
Condensate drain is installed.
Avoiding excessive accumulation of condensate:
• Adjust cooling water temperature to the necessary cooling capacity.
• Only use unit with sealed switch cabinets and housings.
• Set rated temperature as low as possible, but avoid falling below the dew point.
• Installation of a door contact switch reduces the accumulation of condensate when the switch cabinet is open.
