the structure.

The amount of liquid varies substantially between
installations. The overflow drain needs to be
installed on all Centrex 2000 AF models as you
will have overflow in DC mode and with heavy use
on AC mode.
Check “heating not working”.
To get rid of these, fill the evaporation chamber
with very hot water. Leave overnight.
Drain all Liquid through the overflow drain by tip-
ping the unit up (make sure overflow is hooked
up first)
Connect overflow safety drain (See also increased
usage above)
Check and ensure that the unit is level or tilting
slightly towards the left by placing a 6mm -12mm
shim piece under the right side of the unit.
The fan is a continuously moving
part which will eventually have to be
changed. Do Not turn on and off
daily.
Install the safety drain. If the unit is
being used in DC mode there will be
very little evaporation.
Rake evaporating chamber vigor-
ously at spring startups for cottage
use, and once every other month for
residential use.
