8 Maintenance procedures
Follow all maintenance procedures given in
this chapter and in the user manual. If the
maintenance is not performed periodically
the performance of the ventilation system will
ultimately be compromised.
In this chapter you can find a separate subchapter
for each maintenance action which the user should
not perform. In the user manual you can find the
maintenance action which the user may perform.
You can reset the counter for the filter
change warning in the reset filter count
menu. (INSTALLER SETTINGS > MAIN BOARD
SETTINGS > FILTER SETTINGS > RESET FILTER
COUNT)
You can find the maintenance procedures of the
ancillaries connected to the unit in their relevant
manuals. You can get a copy of a Zehnder manual
from Zehnder.
If it is necessary to replace a part you can order a
service part from Zehnder. In the chapter about the
service parts you can see which special service sets
are available.
Always disconnect the power supply of the
unit before you start working on the ventilation
system. The unit can cause personal injury when
it is open while running. Make sure the unit
cannot switch back on by accident.
Always take ESD-inhibiting measures when
dealing with electronics, such as wearing an
antistatic wristband. The electronics can get
damaged by static charges.
Zehnder recommend that you employ a specialised
cleaning firm to clean the whole ventilation system.
