CONDENSATE DRAIN PAN MAINTENANCE
The condensate drain pan must be kept clean. Clean the plastic pan and its
connection fittings completely with water-based non-abrasive cleaners.
Cleaning must be carried out with the pan removed, by unscrewing the 2 side screws
and the 2 front screws from the pan (fig.20).
Also check periodically that the drain pipe is not blocked, bent or kinked, and has the
required gradient of -0°/+2 along its entire length.
Before starting up the unit, check that the water flows properly into the condensate
drain pan by pouring some water into it.
