Condensate drain
Important information
VP18 is supplied with a reinforced 20 mm condensate drain pipe with an integral water trap.
ATTENTION
Run the condensate drain to the nearest drain, allowing an even fall of at least 1 cm per m. The
overflow from the safety valve for domestic cold water must likewise be led to a visible drain.
ATTENTION
If the unit is positioned outside the climate screen, it is important to secure the condensate
drain against icing. Frost protection of the unit is the installer's responsibility.
The connection of the water trap must be air-tight, otherwise air will be sucked into the unit and
condensate water will remain in the unit. It could cause water damage if the condensate tray overflows
and condensate water runs out of the unit.
After installing the water trap, its function is tested as follows: Fill the condensate tray with water and
start the unit at the highest fan speed level. Allow it to run for several minutes. Check that there is no
water in the condensate tray when the test has been completed (the unit must be connected to the
duct system and the door must be closed during the test).
The water trap may dry out and prevent water from draining from the condensate tray, as air will then
blow into the unit. The water trap should therefore be checked regularly, especially at the end of the
summer, and it should be filled with water if necessary.
Do not cut the pipe
- it is used as water trap
The water trap has been built into the pipe from the factory. It runs from the condensate tray to the
drain.
