WARNING! The design and configuration of the PK Series
Proportioner does not allow its use in potentially explosive
atmospheres, or the pressure and temperature limits
described in the technical specifications of this manual to be
exceeded.
Always use liquids and solvents that are compatible with the unit. If in doubt, consult your PMC
Distributor.
When working with the PK Series Proportioner, it is recommended that the operator wear suitable
clothing and elements of personal protection, including, without limitation, gloves, protective
goggles, safety footwear, and face masks. Use breathing equipment when working with the PK
Series Proportioner in enclosed spaces or in areas with insufficient ventilation. The introduction
and follow-up of safety measures must not be limited to those described in this manual. Before
starting up the PK Series Proportioner, a comprehensive analysis must be made of the risks
derived from the products to be dispensed, the type of application, and the working environment.
To prevent possible injury caused by incorrect handling of the raw
materials and solvents used in the process, carefully read the Safety
Data Sheet (SDS) provided by your supplier.
Deal with the waste caused according to current regulations.
To avoid damage caused by the impact of pressurized fluids, do not
open any connection or perform maintenance work on components
subject to pressure until the pressure has been completely eliminated.
Use suitable protection when operating, maintaining or being present
in the area where the equipment is functioning. This includes, but is not
limited to, the use of protective goggles, gloves, shoes and safety
clothing and breathing equipment.
The equipment includes components that reach high temperatures and
can cause burns. Hot parts of the equipment must not be handled or
touched until they have cooled completely.
To prevent serious injury through crushing or amputation, do not work
with the equipment without the safety guards installed on the moving
parts. Make sure that all the safety guards are correctly reinstalled at
the end of the repair or maintenance work of the equipment.
