CONDENSATE DRAINAGE
The drain pan is equipped with a drain pipe for condensate removal
outside the unit.
Connect the drain pipe, the U-trap (not included in the delivery set) and a
sewage system with metal, plastic or rubber drain hoses (Fig. 9). While laying
the hoses provide the slope downwards min. 3 %. Fill the system with water
prior to connecting it to power supply! During operation the U-trap must
always be filled with water. Provide free drainage for the condensed water,
otherwise it is accumulated inside the unit which may cause the equipment
damage and condensate outflow to the room.
The condensate drainage system is designed for normal operation in
premises with air temperatures above 0 °C!
If the expected ambient air temperatures are below 0 °C the
condensate drainage system must be equipped with heat insulation and
pre-heating facilities.
ATTENTION!
In case of several units mounting connect each unit to an individual U-trap.
Direct condensate drainage with no connection to the drain system is not allowed.
