ROUTINE CLEANING AND SERVICING

The cooling air for the refrigerating machine is sucked in through the liquefier in the base of

the housing (16). The liquefier should be cleaned from time to time. To do this, tip the

discharged unit onto its back. The fins of the black liquefier can now be cleaned using a

brush or vacuum cleaner. Never use pointed or sharp-edged tools for this purpose, however,

make sure the fins of the liquefier are not damaged or deformed as this will impair air flow.

Use a damp cloth (mild soap solution) to wipe clean the housing and surfaces of the unit.

Never use chlorine bleach or chlorine-based detergents, scouring agents,

ammonia, cleaning wool or cleaning agents with metallic components to clean

the unit, as these will damage the surfaces of the unit. The unit is maintenance-

free. Any repairs which may be necessary must be carried out by an authorized

Heidolph technician. To do so, Heidolph Instruments or your local Heidolph

Instruments Dealer will be happy to help.

DISMANTLING, TRANSPORT AND STORAGE

Dismantling

Switch off the unit and disconnect from the mains. Remove the rotary evaporator and

vacuum pump.

Drain off all the cooling liquid still in the unit (see ASSEMBLY).

Transport and storage

Pack the unit and parts in the original packing and make sure they are packed upright, as

indicated by the arrows on the packing. If the original packing is no longer available, make

sure adequate alternative is found and that the unit is transported upright (mark the packing

with arrows).

The ROTACOOL may not be tipped or laid on its side during transport.

DISPOSAL

Please make sure that any old units or defective parts are disposed of only by specialist

builders of refrigeration plant (environmental disposal of the refrigerant). Please also dispose

of the packing materials in an environment-friendly manner (sorting).
