Jesco MEMDOS E, Operation Manual

Page: 6 / 52

CAUTION!
If connections at the dosing head are loosened during operation, for venting or other reasons, leaking chem-
ical must be removed properly. This is the only way to avoid health hazards due to chemicals, and chemical
corrosion of the dosing pump. Leaking chemical may also damage the diaphragm at its mounting edge.
ATTENTION!
If changing the chemical, check the materials in the pump and other system parts for chemical resistance. If
there is a danger of chemical reaction between the different media, clean thoroughly beforehand.
IMPORTANT!
To operate the pump, mount the fan cowl in order to ensure sufficient cooling of the motor.
The protection class of the control unit is only ensured if the connection ports are protected by caps or the
standard connectors are inserted.
DANGER!
Fire hazard. Shock wave: parts may fly off and cause fatal injury. MEMDOS DX must never be used in areas
with a potentially explosive atmosphere.
CAUTION!
Under certain operating conditions, the drive motor of the DX version might heat up considerably. This may
cause burns to the hands. To avoid unintentional contact, provide an appropriate safety device.
WARNING!
Lethal voltage!
Adjustment work inside the ATE servomotor (optional for MEMDOS E) must be carried out carefully. Connec-
tions and internal limit switches might be live. Additional limit switches might be live even when the auxiliary
voltage is switched off (ATE servomotor). After installation work on the ATE servomotor, or before start-up,
re-attach the cover.
1.12 Transportation
No special devices are required for transportation of the dosing pumps. However, it is advisable to choose a
transport method appropriate for the weight of the dosing pumps (e.g. transport trolley). If transporting with
the oil drained, the dosing pump should preferably be placed in the horizontal position. Otherwise, stability
must be ensured by screwing it onto the transport frame.
1.13 Scope of delivery
IMPORTANT!
Carefully unpack the dosing pump and any accompanying accessories ordered, so that small parts are not
left inside the packaging. Compare the delivery content with the delivery note immediately. If there are any
discrepancies, find out the cause.
The following are part of the scope of delivery:
• MEMDOS dosing pump
• Suction and discharge side connections
• Gear oil
