WARNING!
Warning about personal and material damage
EX pumps only: When operating in EX areas, certain sub‐
jects must be observed.
– The chapter "Important supplements for metering pumps
in EX zones" of the "General Operating Instructions on
ProMinent
Accessories" must be observed in all cases.
CAUTION!
Possible environmental and material damage
The screw plug in the oil filler neck is factory-fitted and,
during operation, prevents any pressure equalisation
between the power end housing and the surroundings. This
ensure that oil can be pushed from the power end housing.
– Replace the screw plug on the oil filler neck by the air
vent plug supplied.
– Retain the sealing plug for subsequent transport of the
unit.
CAUTION!
Single head version only: Oil may escape
The screw plug in the oil filler neck is factory-fitted and,
during operation, prevents any pressure equalisation
between the drive housing and the surroundings. This
ensure that oil can be pushed from the drive housing.
– Ensure that the hole in the metal cap on the drive flange
is always clear - see "Overview of equipment, control
elements".
CAUTION!
Warning about personal and material damage
Also observe the "General Operating Instructions for ProMi‐
nent Motor-Driven Metering Pumps and Hydraulic Accesso‐
®
ries"!
Replace the sealing screw at the oil filler neck with the supplied vent screw
- see chapter "Overview of equipment and control elements".
When the pump is idle, check whether the pump oil level slightly covers
the lower oil inspection window.
This indicates that the pump has not lost oil and consequently been dam‐
aged.
When commissioning the unit, check whether the drive motor is rotating
correctly - check this against the arrow on the motor housing or the dia‐
gram in the chapter entitled "Electrical Installation."
