13.5 Maintenance of the Ultra for cooling
A float switch monitors the water level and switches the pump off
if the maximum condensation level is exceeded. An alarm contact is
triggered in the event of a malfunction of the condensation drain. We
would recommend automatically terminating cooling operation when the
maximum condensation level is reached to prevent the condensate tray
from overflowing.
Regular visual control and simple maintenance including cleaning the
external pump sump and float switch can be performed without removing
the housing cover! Simply remove the discharge slats in the discharge field.
This makes the pump sump, external condensation tray and float switch
accessible for visual control and simple maintenance.
Important:
The nuts used to fix the condensation tray and metal holding strips for the
float switch are what are known as plug-in nuts. When fitted, they can be
screwed in or plugged in and thus significantly shorten the installation time!
Simply unscrew the plug-in nuts upwards to loosen the holding strip
including float switch from the unit.
