To reduce the risk of fire, electrical shock and injury to persons, the following safety
instructions shall be used:
• This pump is intended for indoor use with water only (max 25°C).
This pump is NOT SUBMERSIBLE.
Disconnect ALL power supplies before starting installation, connection or
maintenance work.
This pump is provided with a grounding conductor. To reduce the risk of electric
shock, be certain that it is connected only to a properly grounded, grounding type
receptacle.
During electrical installation, make sure this condensate pump is connected to a
circuit having a switch with contact separation in all poles that provide full
disconnection from the power supply under over-voltage categories III.
During electrical installation, a fuse non-time delay (rated 250V 1A), shall be fitted
into the line, supply side, see electrical installation section.
The power cord is not replaceable. If the power cord is damaged then the entire
pump must be replaced.
Children should be supervised to ensure that they are not left unattended in the
area where the pump is in use.
Children or persons with reduced physical, sensory or mental capabilities which
