15.5 CHECK AND CLEANING
CONDENSATE DRAINS
The condensate drainage pipes and sys-
tems must operate perfectly to ensure
proper operation of the plant. Check the
functioning at regular intervals.
Remove any deposits or blockages in the
discharge pipe and siphon.
The condensate drainage pipes are cleaned
by rinsing with lukewarm water.

A functional test of the condensate drain-
age system must be conducted after com-
pletion of cleaning. Fill the condensate tray
with sucient water to do this. Make sure
that the water in the tray flows safely into
the drain via the condensate drainage pipe.
Ensure that the system is watertight.
Fill the odour trap (siphon) with water
before switching the unit back on to prevent
unpleasant smells and leaks.

INSPECTION OF THE COOLING
CIRCUIT
Refrigerant circulation of the heat pumps is
basically maintenance-free. Certified tech-
nical sta should, however, regularly check
proper functionality of the apparatus in the
course of inspections.
