OPERATION & MAINTENANCE
OPERATION
The shaft seal depends on water for lubrication and cooling. Do not
operate the pump unless it is submerged in water as the seal may be
damaged if allowed to run dry. Allowing the pump to run dry will void
the warranty.
An automatic overload protector in the motor will protect the motor
from burning out due to overheating/overloading. When the motor
cools down, the overload protector will automatically reset and start
the motor.
If the overload trips frequently, check for the cause. It could be a
stuck impeller, wrong/low voltage, or an electrical failure in the
motor. If an electrical failure in the motor is suspected, have it
serviced by a competent repairman.
The pump is permanently lubricated. No oiling or greasing is required.
Purchase vent and
discharge pipes locally.

MAINTENANCE
Hazardous voltage. Can shock, burn, or kill. Before
removing the pump from the basin for service, always disconnect
electrical power to the pump and the control switch. Do not lift the
pump by the power cord. See the "Cord Lift Warning" on Page 3.
Always wear gloves when handling the pump for service or
maintenance.
NOTICE: The pump should only be serviced by trained personnel.
There are no consumer serviceable parts inside the pump.
After removing the basin cover and the necessary discharge piping,
lift the pump out of the basin.
Disinfect the Pump
1. Place the pump in an area where it can be cleaned thoroughly.
Remove all scale and deposits on the pump.
2. Submerge the complete pump in a disinfectant solution (made
with chlorine bleach) for at least one hour before disassembling
the pump.
3. The pump motor housing contains a special lubricating oil which
should be kept clean and free of water at all times.
4. The sump basin and cover, pump, and piping should be protected
from freezing temperatures. If there is any danger of freezing
temperatures, the unit should be drained. Consult your pump
manual for instructions on how to drain the pump to protect it from
freezing.
