Operation - Zoeller X6161 Manual De Propietario

GENERAL
Zoeller Engineered Products' pumps are lubricated and tested at the factory prior
to shipment and require minimum pre-start-up maintenance.
Maximum operating temperature of pump liquid must not exceed
104 °F (40 °C).
These units are not designed to handle liquids other than effluent: X6160 and
X6180 or sanitary sewage: X6280, X6290 and X6400. If pump is used to dewater
areas with contaminated liquids with heavy or abrasive materials, the warranty
will be voided.
NAMEPLATE DATA
The nameplate, located on the side of the pump, indicates specific information
about the construction of the pump. The model number and date code informa-
tion should be recorded on the front page in the "Owner's Information" section
of this manual.
SHORT TERM STORAGE
When not in use, the pump should be stored and the following is advised:
• Store pump inside whenever possible or cover with some type of protective covering.
• Tape or seal in plastic bag the terminal ends of wire leads.
• Spray coat unpainted surfaces with rust inhibiting oil.
• The impeller should be rotated every six months in order to keep the seals
lubricated and not develop a permanent set.
If panel is to be stored, the following is advised:
• Store the panel inside whenever possible and leave in the shipping box.
• All openings shall be sealed.
• Store in an upright position.
• Do not stack anything on top of panel.
START-UP PROCEDURE
Before placing the equipment into operation the following should be checked:
• Clean pit.
• Electrical boxes dry and securely installed.
• Floats positioned properly.
• Discharge valves open.
• 3/16" (4 mm) vent hole drilled in pipe between check valve and pump.
Once the previous has been verified proceed with the following checks:
• Pump power cables and control floats properly installed and voltage verified.
• Conduit connections to panel are properly sealed.
• After installing the pump into the containment area, with adequate submergence,
open the shut-off valve fully. Start the unit using manual controls. If flow is
appreciably less than rated performance, pump may be air locked. To expel
trapped air, jog the unit several times, using the manual controls.
• Have a qualified electrician take voltage and current measurements with the
pump running. Record these readings in the space provided in the "Owner's
Information" section on page 1 of this manual for future reference.

No adjustments are required.
Nonautomatic - Refer to the system drawing or to the panel wiring
schematic for the desired location of each float switch setting.
For non-automatic Class II, Div.1 (alternate Zone 20 designation) rated
models, the float switch "off" level must be set to a minimum of
10 inches for the X6160-X6190, X6280, X6290 series and 13 inches for
the X6400 series.
Discharge valves should be placed in the fully open position. Systems
should not be operated for extended periods of time with the discharge
valves partially closed due to damaging the valve.
If pit is to remain dry, then the pump can remain in the pit. With the
pump in the pit, it should be operated for five minutes once every three
months. If the pit is to remain wet, the pump should be removed and
stored as noted above.
The panel should have all openings sealed to prevent moisture and dust
from entering the enclosure. Prior to restarting system, the panel should
be inspected for presence of moisture and any loose connections.
Consult the valve/actuator supplier for information concerning these
systems components.
