1. General Information and Safety 
Instructions 
The products supplied by SPP Pumps Ltd. have 
been designed with safety in mind. Where hazards 
cannot be eliminated, the risk has been minimised 
by the use of guards and other design features. 
Some hazards cannot be guarded against and the 
instructions below MUST BE COMPLIED WITH for 
safe operation. These instructions cannot cover all 
circumstances: YOU are responsible for using safe 
working practices at all times. 
1.1
SPP Pumps Ltd. products are designed for 
installation in designated areas, which are to 
be kept clean and free of obstructions that 
may restrict safe access to the controls and 
maintenance access points. 
A pump nameplate is fitted to each unit and 
must not be removed. Loss of this plate 
could make identification impossible. This in 
turn could affect safety and cause difficulty in 
obtaining spare parts. Should accidental loss 
or damage occur, contact SPP Pumps Ltd. 
immediately. 
1.2
Access to the equipment should be restricted 
to the personnel responsible for installation, 
operation and maintenance and they must be 
trained, adequately qualified and supplied with 
the appropriate tools for their respective tasks. 
1.3
SPP Pumps Ltd. requires that all personnel 
that are responsible for installation, operation 
or maintenance of the equipment, have 
access to and study the product instruction 
manual BEFORE any work is done and that 
they will comply with all local and industry 
based safety instructions and regulations. 
1.4
Ear defenders should be worn where the 
specified equipment noise level exceeds 
locally defined safe levels. Safety glasses or 
goggles should be worn where working with 
pressurised 
systems
and
hazardous
substances.
Other
personal
protection
equipment must be worn where local rules 
apply. 
1.5
Do NOT wear loose or frayed clothing or 
jewellery that could catch on the controls or 
become trapped in the equipment. 
1.6
Check and confirm that the manual is the 
relevant copy by comparing the serial number 
on the identification plate with that on the 
manual.
