General Precautions
Explosion Prevention
In order to reduce the possibility of accidental explosions in atmospheres containing explosive gasses
and/or dust, the instructions under the ATEX symbol must be closely followed. ATEX certification is a
directive enforced in Europe for non-electrical and electrical equipment installed in Europe. ATEX
requirements are not restricted to Europe, and are useful guidelines for equipment installed in any
potentially explosive environment.
Special ATEX considerations
All installation and operation instructions in this manual must be strictly adhered to. In addition, care must be taken to
ensure that the equipment is properly maintained. This includes but is not limited to:
1. monitoring the pump frame and liquid end temperature
2. maintining proper bearing lubrication
3. ensuring that the pump is operated in the intended hydraulic range
Never apply heat to remove impeller. It may explode due to trapped
liquid
Never use heat to disassemble pump due to risk of explosion from
trapped liquid
Never operate pump without coupling guard correctly installed
Never operate pump beyond the rated conditions to which the pump was
sold
Never start pump without proper prime, or proper liquid level in self
priming pumps
Never run pump below recommended minimum flow or when dry
Always lock out power to the driver before performing pump maintenance
Never operate pump without safety devices installed
Never operate pump with discharge valve closed
Never operate pump with suction valve closed
Do not change conditions of service without approval of an authorized
