To achieve maximum output from the PH Series Proportioner, a daily or regular mainte-
nance schedule is required.
To prevent possible injury caused by incorrect handling of the
raw materials and solvents used in the process, carefully read the
Material Safety Data Sheet (MSDS) provided by your supplier.
Deal with the waste caused according to current regulations.
Disconnect the unit from the power supply before carrying out
any operation inside the electrical console. The electrical main-
tenance of the machine must only be performed by a qualified
electrician.
To avoid damage caused by the impact of pressurized fluids, do
not open any connection or perform maintenance work on com-
ponents 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 in-
cludes, 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.
CAUTION! All repairs performed by unqualified personnel or
the use of parts other than supplied by PMC may cause damage
to the unit and put the operator at risk.
