The refrigerant may not be discharged into the atmosphere, but must be returned to
the manufacturer, if it is not reused.
The ester oil in the compressor must also be disposed. As it contains dissolved
refrigerant, it cannot be disposed like usual oils, but must be returned to the oil
manufacturer.
If glycol or similar additives had been used, this liquid also has to be collected and
disposed in an appropriate manner and may under no circumstances be introduced in
the local waste water system.
9 Dismantling and disposal
The air handling unit can only be dismantled by qualified specialists.
Switch off the unit at the controller and at the master switch Switch off power con-
ducting cables to the unit and secure them against being switched on again Discon-
nect the chiller from the de-energized network
Dispose of the refrigerant in the unit in accordance with the disposal and safety regulations
applicable on site
Disconnect the unit from the external water circuit by closing the shut-off valves and drain the
water circuit of the unit.
Move the unit, as described in the chapter “transport”, with a lifting device of sufficient load-car-
rying capacity.
Dispose of the air handling unit in accordance with the disposal and safety regulations applica-
ble on site. We recommend a recycling company for this. The unit basically contains the follow-
ing raw materials:
• Aluminium (profiles, heat exchanger coils, plate heat exchanger).
• Stainless steel (condensing tray, adiabatic sump).
• Galvanized steel (frames, panels, roof).
• Zinc aluminium (panels).
• Copper (pipelines, wiring)
The electrical and electronical components installed in the electric cabinet must be separately
disposed of according to the European directive 2012/19/EU. The concerned components are
marked by the symbol of the crossed-out wheeled bin.
