the supply and return line of the heat pump. The
regulations of the trade associations must be
adhered to. If in doubt, contact the manufacturers of
the chemicals!
To prevent consequential damage it
is imperative that the water circuit be neutralized
after cleaning using appropriate agents.
Caution - Heating Engineers
Depending on the water quality and quantity, in
particular in the case of mixed installations and
plastic pipes, mineral deposits (rust sludge, lime)
may form impairing the proper functioning of the
heating installation. A cause of this is the water
hardness as well as oxygen dissolved in the filling
water as well as additional oxygen from the air which
may penetrate via valves, fittings and plastic pipes
(oxygen diffusion). As a preventive measure it is
recommended that a physical water conditioner such
as ELYSATOR be used.
8.3 Cleaning of Air Side
Evaporator, fan and condensate drain should be
cleaned of debris (leaves, branches, etc.) from time
to time. To this end, the front panel of the heat pump
should be opened first at the bottom and then at the
top.
Prior to opening the unit it must be
ensured that all electrical circuits are disconnected
from the power source.
The removal and reinstallation of the panel
assemblies to be performed as described in
Chapter 4.
When cleaning do not use any sharp or hard objects
so as to prevent any damage to the evaporator and
the condensate pan.
