Disposal
This unit contains refrigerant gas, which must NOT be discharged to the
atmosphere. At the end of the unit’s working life, either have the gas re-
moved safely by using refrigerant recovery equipment or return the unit to
us for disposal.
Ensure that the mains switch is easily accessible during use.
Ensure the cooling unit is placed on a firm level surface.
Do not block or restrict ventilation slots.
If liquid is spilt inside the unit, disconnect it from the power supply and have
it checked by a competent person.
It is the user’s responsibility to carry out appropriate decontamination if
hazardous material is spilt on or inside the equipment.
Before moving, disconnect at the power supply socket.
