Rotation Direction; Starting Up; Preliminary Checks; Operation - FPZ SCL K07 MS Betriebsanleitung

When using the unit with a motor powered via an inverter,
follow the wiring instructions supplied
manufacturer carefully.
WARNING!
The performance of the unit powered via an inverter is
shown in the relevant tables that can be requested from
FPZ's assistance service.
4.2.3

ROTATION DIRECTION

The SCL K compressors – suction pumps must be used with the
rotation direction shown by the arrow on the fan guard for the
electric motor (see figure below).
To check the direction of rotation, switch on the motor very
briefly. If the rotation direction is incorrect, switch the position
of two of the three power supply conductors on the terminals.

STARTING UP

Any use other than the intended use of the
unit may cause serious injury and even
death!
The unit may only be started:
After having carefully read, fully understood, and complied
with this operating manual ("SAFETY STANDARDS" and
"INSTALLATION").
In conformity with the purposes laid down under
"INTENDED USE".
According to the
"CHARACTERISTIC DATA" table on page 3/4.
Danger due to rotating components (electric
motor fan, impeller, and shaft):
shearing of limbs, entanglement or trapping
of hair or clothing!
Danger due to excess pressure or vacuum:
Sudden ejection of process fluids (injury to
the skin and eyes), and sudden sucking in of
hair and clothing!
Danger due to process fluids that come out
and cause burns!
Danger due to burns caused by contact with
hot surfaces on the unit!
Electrical danger!
Danger due to the impeller seizing due to use
in an unsuitable
conveying fluids that are
Unsuitable
temperatures!
Danger resulting from the impeller seizing
due to the

exceeding the
openings closed!
Danger due to noise emitted by the unit!

PRELIMINARY CHECKS

Before finally starting up, carry out the following preliminary
checks:
If a lot of time has passed since the unit was last started
-
up, check its condition and check for and if necessary
remove dust deposited on the external surfaces.
Deactivate/open any closing elements on the piping
-
(closing valves, solenoid valves, etc.) before starting the
unit.
Do not allow the unit to be started and operate with
the suction and/or delivery openings obscured for any
reason!
Check that the ambient and suction temperatures for the
-
gas conveyed are between:
(+104°F).
Check the rotation direction as indicated previously in the
-
"INSTALLATION" chapter.
Check that the setting for the motor trip switch corresponds
-
to the motor's nominal current shown on the nameplate.
- Check that the safety valve is working correctly.

OPERATION

Having carried out all the preliminary checks, you can start with
final starting of the unit.
Start the unit by switching on the power supply to the electric
motor.
Check the operating pressure or vacuum and compare them to
the values indicated in the "CHARACTERISTIC DATA" table on
page 3/4. Load losses on the pipes are often underestimated
but are determining factors for the operating pressure
differential.
Measure the motor's absorption and check against the
nameplate value.

ROUTINE CHECKS

It is important that the units be checked routinely while running
by qualified personnel, using inspections to avoid faults that
to
may cause damage directly or indirectly.
When the unit is running, routinely carry out the following
checks:
- Delivery temperature
- Operating pressure and/or vacuum
Electric motor current absorption
-
Vibrations
-
State of the filter and related load loss.
-
Variations in normal working conditions (increases in power
absorbed, anomalous noise, vibrations, excess overheating of
the service fluid) indicate that the unit is not working correctly.
