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.
